201228852 六、發明說明： 【發明所屬之技術領域】 本揭示内容係關於安全結構，且更特定言之係關於併入 多層驗證特徵之安全結構，諸如護照。 【先前技術】 安全結構（例如，安全證件）之驗證持續受到關注以用於 多種目的，舉例而言邊境安全。為了防止證件的偽造，已 採取多種方法包含舉例而言目視驗證方法。此等目視驗證 方法可包含在一證件上提供不透明度經修飾之區，例如浮 水印及/或偽浮水印。 EP A 1 122 360描述產生一網印淡浮水印，即具有較淡 區域之浮水印（每單位面積密度低於片材之一證件紙區 域）。 已結合浮水印使用額外光學安全特徵。舉例而言，德國 申請案DE 10 2005 022 5 18描述一種包括一浮水印及印刷 墨之安全紙，該印刷墨係經組態以在被紫外（UV)光照射時 發光。安全紙僅在浮水印區域對VU光透明。 此外，已將諸如舉例而言電子裝置（例如，電子晶片）之 電子方法引入安全結構中以實現此等結構之更高級別的驗 證。此等電子裝置可含有當特殊設備可用於擷取電子裝置 上所儲存之資訊時可被讀取之資訊（例如，RFID)。舉例而 言，Rawson之美國專利第5 949 059號描述具有目視及電 子驗證構件之一標藏。但是，用於驗證此資訊之此電子設 備可能十分昂貴且因此許多驗證機構難以獲得。 156632.doc 201228852 國際申請案WO 2007/034129揭示一種護照及製作此一證 件之方法。其中所述與一護照之製作有關之技術有助於理 解此製作。 存在改良安全結構之安全方面同時維持合理成本且無須 用於執行驗證之昂貴系統之結構的需要。 亦須提高安全結構（舉例而言護照）之驗證之冗餘。 亦須改良篡改安全結構之企圖之證據。 因此，本揭示内容之一目標係提供一種實現驗證之安全 結構。 【發明内容】 特定言之一種諸如 本揭示内容之實施例提供一種結構 -護照的安全證件。結構包含一第一層，丨包括不透明度 經修飾之U少—額外層，其係相對於第-層固定； 及-發光劑’其係相對於至少一額外層及第一層定位使得 在發光劑激發時發光劑所產生之光傳播穿過第一層以變得 可觀察到且清晰呈現不透明度經修飾之區之特徵(例如一 設計輪廟及/或圖案）。不透明度經修飾之區在從安全結構 :任何側透射的光中不可見。該結構較佳A「撓性」，其 思未著可彎曲及/或可摺疊，如舉例而言***、ID卡、 護照、鈔票、票、及其他安全證件。 在產生此一結構時，當一機構具有有限方法但認為2級 驗證足夠時可實現驗證，可僅基於透制—預定形式之電 輻射(例如、红外及’或紫外光)照射而觀察不透明度經修 飾之區而進行驗證。 156632.doc 201228852 此外’可在結構上隱藏不透明度經修飾之區之存在，藉 此可防止偽造者發現如何實現結構複製，此外，因第一層 在不透明度經修飾之區内可具有一減小厚度，故試圖將第 一層與至少一額外層分開可能至少對不透明度經修飾之該 區造成損壞’這可易於透過發光劑之照射簡單地識別，藉 此提供額外的防篡改β 不透明度經修飾之區較佳為不透明度減小之一區。且較 佳係不透明度減小之區至少部分疊加在發光劑上。 發光劑可藉由紫外光及紅外光之至少一者激發。 發光劑可佈置在一安全帶上。在一些實施例中，安全帶 可位在至少一額外層與第一材料層之間。安全帶較佳由纖 維材料（較佳紙）製成。安全帶可具有小於至少一額外層之 一表面積之一表面積，藉此可導致結構製造方面的成本節 省。 在本揭示内容之例示性實施例中，安全帶從部分意義而 言僅延伸在至少一額外層之表面積之一部分上方。在此情 況下，安全帶較佳延伸在足以置於第一層之不透明度經修 飾之區下之至少一額外層之一區域上方。 在例示性實施例中’不透明度經修飾之區足夠透明以容 許照射光能夠在發光劑激發時透射穿過第一層。特定言 之’當實施不透明度減小之一區時，該區可具有為第一層 之厚度之約10%至約90%之一最大深度。 不透明度經修飾之區可為一浮水印及/或一偽浮水印β 不透明度經修飾之區較佳為不透明度減小之一區。浮水印 I56632.doc ，6 - 201228852 較佳為一淡浮水印，其在面向至少一額外層之第一層之側 上具有凹部。舉例而言，淡浮水印可為如EP 1 122 36〇中 所揭示之一網印浮水印。當不透明度經修飾之區之不透明 度增大時，證件紙足夠透明故不透明度經修飾之區之特徵 出現（例如，負相）。 、’’σ構可包含與第一材料層相接觸之一層壓保護層。 第一材料層可包含一纖維材料，較佳紙。此外，至少一 額外層可包括一不透明層，該不透明層在其整個表面區域 上不透明。不透明度經修飾之區僅在發光劑激發期間對裸 眼可見。 第一層及至少一額外層皆可接合在一起或經選擇之層可 個別地彼此接合β可舉例而言使用層壓執行接合。可接合 第層與至少一額外層使得試圖脫離（舉例而言藉由撕毀） 對不透明度經修飾之區造成損壞。這可提供篡改之證據。 至少该第一層較佳包含一安全紙。紙之重量可舉例而言 處於70克/平方米（g/m2)至18〇 g/m2之範圍中。 發光劑指的是回應於外部刺激/激發而發射光之物質。 舉例而言，發光劑可回應於光刺激發射光（即光致發光）、 化學刺激發射光（即化學發光）、電刺激發射光（即電致發 光）、及/或機械刺激發射光（即摩擦發光）。 發光劑較佳為回應於光刺激之一光致發光劑，舉例而言 紫外（UV)及/或紅外線，且更特定言之—uv發光劑。 發光劑可包含一發光墨、一發光纖維、一發光顏料、一 發光平坦安全7L件（諸如一「防偽標識（planchette)」）及一 156632.doc 201228852 發光黏合劑之至少一者。舉例而言，在黏合諸層時，可將 發光劑與所使用之一黏著劑混合。舉例而言，發光劑可以 乾重量計至多50%與一黏著劑混合。 結構可包含至少部分佈置在至少一額外層内之一電子裝 置。電子裝置可經組態以提供與結構及結構之所有者之至 少一者相關之資訊。 至少一額外層可包括一第二層及一中間層。 電子裝置可為舉例而言一 RFID裝置。此外，電子裝置 可包括至少部分接觸中間層之一天線，天線因試圖將第一 層從另一接合層上脫離而損壞。這提供額外的篡改證據。 可將電子裝置至少部分佈置在第二層中。 可將發光劑佈置在中間層上及/或一中間材料層内。 第一層及/或至少一額外層可包括一可壓縮紙，舉例而 5諸如歐洲專利申請案EP 2 174 270所揭示之紙。 結構較佳為一護照且包含一護照封面，第一層及至少一 額外層為該濩照封面之部分。此外，第一材料層可形成護 照封面之正面頁或背面頁之一者。第一層最初為多頁小冊 子之。卩刀，其隨後舉例而言膠合至至少一額外層以形成護 照封面之正面頁或背面頁。 激發光可傳播穿過不透明度經修飾之區以激發發光劑。 在本揭不内容之另一實施例中提供一種製作如上所述 之、’·。構之方法。方法可包含在第一材料層内形成不透明 度經修飾之—Fτ、* ^ 將不透明度經修飾之區至少部分疊加在 發光劑之至少—邱八L丄 夕 刀上方，及接合第一層與至少一額外 156632.doc 201228852 層。 接合步騎可包含層壓及/或可包含施加一黏著劑。黏著 劑可包含一或多個發光劑。 材料之至少一額外層及第一層可在不同於其他層之一製 造位置製造。 不透明度經修飾之一區可為在製作期間蝕刻在或壓入一 纖維層中之一設計。舉例而言，可藉由在一圓網抄紙機上 製作纖維層時產生厚度減小或增大之紙漿區域而產生此不 透明度經修飾之一區’這藉由在圓網籠之成形網中之一外 凸或内凹的印痕而達成。 不透明度經修飾之一區亦可來自已藉由一加浮水印滾筒 (其包含钱刻為浮雕之不透明度經修飾之區）而抵著一平台 長網造紙機（Fourdrinier machine)壓著纖維層藉此生效之區 域’同時在機器之潮濕部分中用力壓著纖維層之特定區域 並因此擠出纖維中所含之水而形成纖維層。 可藉由施加特定物質而藉由機械及/化學方法在一製成 纖維層中製作不透明度經修飾之一區，此設計透明度仍可 見。 舉例而言，可藉由將一組合物放置或印刷在纖維層之經 決定區域而製作不透明度經修飾之一區，該組合物修飾纖 維層之透明度，尤其用以提供與浮水印之淡區域及暗區域 類似之淡區域及暗區域，而不會得到使其能夠獲得可比擬 於一習知浮水印之精度及變色之精度及變色之結果。 舉例而言，可藉由施加例如一大致脂肪組合物至製成纖 156632.doc 201228852 維層之經決定區域而使製成纖維層更透明，該組合物使得 纖維層永久性地更加透明，諸如舉例而言如美國專利第2 〇21 141號所述之由油及一透明礦物質材料組成之一組合 物’或舉例而言如美國專利第1 479 337號所述之缫結合一 >谷劑之形式之一組合物。 亦可藉由如美國專利第5 118 526號所述藉由熱傳遞而局 部施加一蠟、如GB 1 489 084所述可在輻射下聚合之一流 體透明化組合物、或如DE 3 920 378所述藉由印刷而施加 之基於聚醚、脂肪族異氰酸酯、及乙醇之一組合物而使製 成纖維層更透明。 ^ ^使用包含一熱溶材料（諸如舉例而言如EP 〇 203 499 所述之聚乙烯）之一纖維層，該纖維層在局部熱作用下經 受透明度之變化。 可例如如專利申請案FR 2 353 676所述藉由在經決定區 域中施加一不透明劑以增大纖維層之不透明度而將第一纖 維層製作為更加不透明而不製作為對照射光完全不透明。 舉例而言，不透明劑可為一顏料或一填充物之一水懸浮液 或一化學組合物、一有色組合物或一染料之一溶液。可在 製作第一層的同時及在將第一層從織物上移除前將該劑施 加至第一層上使得該劑滲入片材之孔隙中並在乾燥後產生 片材之不透明度之修飾用於在所選擇區域中處理。製作技 術具有需要用於施加該劑之特殊滾動裝置，及為獲得更好 效果而需要使用一吸氣裝置使該劑滲入片材之孔隙中之缺 點。 156632.doc •10- 201228852 亦使用 W. Walenski 之文獻「Watermarks and those that are not」Druckspiegel 52 第 3冊：66 頁-68 頁（1997年3月）中 所述之方法製作不透明度經修飾之_區。該文獻描述一種 在未塗佈紙上製作一偽浮水印之方法，方法包含用熱及之 壓力抵著一張再濕潤之紙施加表示偽浮水印之圖案之一標 記件。 亦可藉由用熱及壓力在紙之一或多個經決定區域上施加 一再濕潤溶液以在經決定區域中使溶液蒸發並使紙密化而 在未塗佈紙上製作不透明度經修飾之一區。 國際專利申請案WO 97/Π493亦描述製作包含偽浮水印 之經塗佈紙，偽浮水印因施加在經決定區域中之層之重量 之變化藉此產生其中塗層重量減小或增大之此等區域中之 厚度及不透明度之變化。 國際專利申請案购99/〇14433亦描述在經塗佈紙上藉由 知行八中將ϋ濕潤溶液施加至經塗佈紙之至少一面上之 -或多個經決定區域及在經塗佈紙之該等區域中施加壓力 及在其中相對於紙之其餘部分蒸發溶液及使經塗佈紙 在化之步驟’而製作_偽浮水印之另一方法(該方法涉及 在緊隨最後塗佈操作 = 、乍之乾煤步驟後在紙中製作一影像）。 最後，如專利DE 1 71。>· π 、 1 8 452所述可藉由在纖維層之經決 定區域中機械式浮雕 _ 製作彳示記從而機械式製作不透明度 經修飾之一區。 殂合物 亦可籍由施加適於修飾聚合物層之透明度之 在-聚合物層中製作不透明度經修飾之一區。 156632.doc -11· 201228852 申請案WO 91/07285描述在一合成介質上印刷一組合 物，.該組合物修飾支撐物之不透明度且含有至少一礦物質 填料及至少一接合劑及一可溶或顏料著色劑。在經決定區 域中施加該組合物且隨後使用熟習此項技術者所知之塗佈 方法用一可印刷顏料組合物塗佈介質之整個表面。 美國專利第4 307 899號描述一種驗證卡，其包括藉由印 刷部分疊加之有色層而在一介質（較佳一塑膠介質）上形成 之一印痕。印有一單層之區域在透射光中看起來淡且在反 射光中看起來暗，且印有複數個疊加層之區域在透射光中 看起來暗且在反射光中看起來淡，藉此產生一浮水印效 果。藉由修飾層數可獲得多色調效果。 亦可藉由使用機械式方法在一聚合物層中製作不透明度 經修飾之一區。 舉例而言’如EP 0 655 3 16所述可藉由使片材在兩個滾 筒間穿過而在一片聚合物材料上製作一偽浮水印，滾筒之 一者攜載浮雕狀之一内凹或外凸圖案以形成一印記。隨後 藉由將片材拉伸而使片材定向使得圖案在透射光中看似黑 色及白色’對應於藉由滾筒而標記為凸部或凹部之區域。 國際專利申請案WO 2007/016148亦描述適於變形之一塑 膠層，特定言之藉由浮雕或壓凹而衝壓以形成看似一浮水 印之一影像且隨後被層壓而不損壞已形成之影像。 此外，可藉由使甩電磁輻射（舉例而言一雷射）而在一聚 合物層上製作不透明度經修飾之一區。舉例而言，申請案 EP 1 518 661描述一種藉由電磁輻射特定區域及藉由拉伸片 156632.doc •12- 201228852 材以獲得呈現對應於被輻射區域之透明區域之一經拉伸片 材而在一卷聚合物片材上製作一偽浮水印之方法。 可使用上述方法之任意者及/或此項技術中已知且本文 中未描述之任何其他方法製作第一層之不透明度經修飾之 一區。 至少一額外層可包括一單層或複數個層。 至少-額外層可為一纖維層或可包括一或多個纖維層。 舉例而言，纖維層可基於纖維素纖維（特定言之棉花纖維） 或合成纖維（諸如舉例而言聚醯胺）及/或聚醋纖維。特 定言之，中間層可為一半透明描圖紙。 第一層及/或至少一額外層可為纖維或聚合物層。

構1之一截面之例示圖。如圖丨A所示，安全結構i可包含一 多頁證件，諸如一護照，其具有一封面7(其具有正面頁及 背面頁）及諸頁35(亦稱作「簽證頁」）。此等護照可包含一 資料頁，其包括與護照持有人相關之資料以及提供安全結 構1上所呈現之各種其他安全特徵之接取。 第一層4包含根據上述技術而形成之不透明度經修飾之 一或多個區40，不透明度經修飾之一或多個區4〇為適於一 特定應用之任何所要形狀及大小。舉例而言，不透明度經 修飾之區40可形如頒發一護照證件之一國家之一形狀或可 經辨識為與安全結構1之一頒發實體相關聯之特定形狀。 可在第一層4上提供任何所要數量之不透明度經修飾之區 40，其中不透明度經修飾之此區4〇係位在第一層4上之任 何所要位置處。舉例而言，可能需要提供經對齊以在第一 層4上形成一特定形狀，或成一直線或任何其他組態之不 透明度經修飾之一或多個區40。 如圖所示，不透明度經修飾之區4〇較佳係位在第—層4 之一底部表面上以面向一中間層3〇。換言之，一旦與其他 層裝配，不透明度經修飾之區4〇係位在第一層4之一内部 156632.doc •15- 201228852 部分上。當不透明度經修飾之區40以此方式定向，其不會 顯現在第一層4之一表面上，藉此實現不透明度經修飾之 區40之額外隱藏。應/主意，不透明度經修飾之區4〇足夠透

根據一些實施例，中間層30可包括一可壓縮材料，例如 一可壓縮紙，其使得額外元件可添加在第一層4與_間層 30之間及/或中間層30及/或第二層6而不大體上增大與安^ 結構1相關之一厚度。中間層3〇包括一紙材料且更特定言 之的一可壓縮紙材料，紙材料層3〇較佳包括以重量計至少 百分之15的合成纖維及/或以重量計至少在百分之5與2〇間 之現有乳夥（諸如丙稀酸醋）。需要此組合物之紙張係基於 其連同其他7〇件之添加而縮，藉此關或免除結構之厚 度隨此等元件之添加而增大之能力。舉例而言，如下文更 詳細之描述實施一安全帶45，須使用可壓縮材料之此一令 間層3 0。 中間層30可進—步經組態為具有與第一層4大體上類似 之表面區域’具有此等類似長度及寬度部分。此一組態使 156632.doc •16- 201228852 中間層30可與第一層4大體上對準。 根據本揭示内容之—些實施例，中間層30可包括一發光 劑37，其係佈置在中間層3〇之一表面及/或散佈在中間層 之整個厚度上。舉例而言’當中間層3()包括—纖維材料 (例如紙）時，可在在絲網上成形前及/或在製造期間之任何 其他適當時點將發光劑37添加至配料中。在此等實施例 中，舉例而言，如圖1C所示，發光劑37可大體上存在在中 間層夂整個表面上。或者，如圖丨A所示，當發光劑37沈積 在中間層30上時，可舉例而言，基於不透明度經修飾之區 4〇之一位置選擇特定位置用於此沈積。較佳，不透明度經 修飾之區40至少部分疊加在發光劑37上。 發光劑37可包含舉例而言一黃色發光顏料，諸如 HONEYWELL公司所供應之Lumilux⑧D14〇。 可能需要為與至少一些纖維材料本身相關聯之纖維提供 一發光劑37。或者，可根據需要在製作（例如在絲網上成 形或乾燥）後或任何其他適當時點將發光劑37施加至中間 層30之一表面。 圖1B及圖5繪示一例示性實施例之圖解，其中作為中間 層30之補充或取代中間層3〇將發光劑37與一安全帶45相關 聯此文全帶4 5可包括任何適當物質（例如，纖維、聚 5物質等）且尤其包含發光劑37。發光劑37可散佈安全帶 45之整個厚度及/或佈置在安全帶45之一或多個表面上。 在此等實施例中，安全帶45係經組態以位在第一層4與中 間層30之間（例如與第一層4及中間層30兩者接觸），使得安 156632.doc •17- 201228852 全帶45之至少部分置於不透明度經修飾之區4〇之至少部分 下。 安全帶45具有小於第一層4及中間層3〇之表面積之一表 面積。舉例而言，在一些實施例中，安全帶45可具有為與 第一層4相關聯之表面積之5〇%或更小之一表面積。根據 一些貫施例，安全帶45之表面積可為第一層4之表面積之 25%、或10%或甚至更小。因發光劑僅存在在安全帶上， 故此一組態可至少舉例而言在製造安全結構丨辩間導致成 本節省。 結合可壓縮材料之中間層30實施安全帶45，較佳在安全 帶45之位置上厚度未感知到增大。這有助於隱藏安全結構 1之安全性且進一步使其偽造更複雜。 雖然有將發光劑37包含在安全結構丨（例如，中間層3〇、 安全帶45、第一層4與封面7之其他部分之間之黏著劑等） 内之方法’但是發光劑37應定位使得發光劑37之至少一部 分置於第一層4上存在之不透明度經修飾之一或多個區4〇 下。以此方式，發光劑37之至少一部分係經定位使得穿過 第一層4(例如穿過不透明度經修飾之區4〇)之光撞擊在發光 劑3 7上，藉此激發發光劑3 7並導致照射光之發射。發光劑 3 7所產生之照射光傳播.穿過第一層以變得可觀察到並藉此 清晰呈現不透明度經修飾之區4〇之特徵（例如，一設計輪 廓或一圖案）。 舉例而言，如圖5所示，當實施一安全帶45時，安全帶 45在一位置上覆蓋中間層3〇使得在將第一層4對應於中間 156632.doc •18· 201228852 層3 0及女全帶45放置時，不透明度經修飾之區4〇覆蓋安全 帶45。類似地，當未實施安全帶45時，發光劑3 7可存在於 中間層30上及/或中之與第一層4之不透明度經修飾之區 相關聯之位置。 中間層30可包含實現電子裝置17之至少一部分之***之 一或多個空腔52。此等空腔52可包含適於接收電子裝置17 之所有或部分之一通孔或一盲孔。舉例而言，如圖4所 示可在中間層30中形成一通孔，可在中間層3〇内將電子 裝置17之一部分至少部分***該通孔。根據一些實施例， 如圖3B所示，可在中間層30内形成一凹部53，凹部53係經 組態以接收一電子裝置17。在又其他實施例中，一凹部可 存在在第二層6及中間層30兩者中，致使各層可接收電子 裝置17之一部分。根據需要可使用許多此等組態以導致如 本文所述之一安全結構丨而不脫離本揭示内容之範圍。電 子裝置17可包含實現安全結構丨之2級別的驗證之任何適當 裝置。舉例而言’電子裝置17〇可包含構成一 RFID裝置之 一電子晶片。 電子裝置17可攜載其自有天線或意欲在與嵌體所攜载之 一放大天線耦合之一天線。 與電子裝置17相關聯之一天線64可靜置於中間層3 〇、第 二層ό、或安全結構丨内所存在之其他層之部分上及/或 内。舉例而言，如圖4所示，在***電子裝置17後但在裴 配中間層30與第二層6之前可能需要將天線64固定至中間 層30使得在層之間接合時，天線64亦被固定在安全結構i 156632.doc •19· 201228852 内。 如圖所示，第二層6可受限於護照封面之一不透明外層

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present disclosure relates to security structures and, more particularly, to security structures incorporating multi-layer authentication features, such as passports. [Prior Art] Verification of security structures (e.g., security documents) continues to receive attention for a variety of purposes, such as border security. In order to prevent the forgery of documents, various methods have been adopted including, for example, visual verification methods. Such visual verification methods may include providing an opaque modified area on a document, such as a watermark and/or a pseudo watermark. EP A 1 122 360 describes the creation of a screen printing pale watermark, i.e. a watermark with a lighter area (density per unit area being lower than one of the document areas of the sheet). Additional optical security features have been used in conjunction with watermarking. For example, the German application DE 10 2005 022 5 18 describes a security paper comprising a watermark and a printing ink which is configured to emit light when illuminated by ultraviolet (UV) light. The security paper is transparent to the VU light only in the watermark area. In addition, electronic methods such as, for example, electronic devices (e.g., electronic wafers) have been introduced into security structures to achieve higher levels of authentication of such structures. Such electronic devices may contain information (e.g., RFID) that can be read when special devices are available to capture information stored on the electronic device. For example, U.S. Patent No. 5,949,059 to Rawson, which is incorporated herein by reference. However, this electronic device used to verify this information can be very expensive and therefore difficult for many verification agencies to obtain. 156632. Doc 201228852 International Application WO 2007/034129 discloses a passport and a method of making the same. The technique described in connection with the production of a passport helps to understand the production. There is a need to improve the safety aspects of the safety structure while maintaining reasonable cost and without the structure of expensive systems for performing verification. It is also necessary to increase the redundancy of the verification of the security structure (for example, a passport). Evidence of attempts to tamper with the safety structure must also be improved. Accordingly, it is an object of the present disclosure to provide a security architecture that implements verification. SUMMARY OF THE INVENTION One embodiment, such as an embodiment of the present disclosure, provides a structure-passport security document. The structure comprises a first layer comprising opaque modified U-less-extra layer, which is fixed relative to the first layer; and - the illuminant' is positioned relative to at least one additional layer and the first layer such that it is illuminated Light generated by the illuminant as the agent is excited propagates through the first layer to become observable and clearly exhibits features of the opaque modified region (eg, a design wheel temple and/or pattern). The opaque modified area is not visible in the light transmitted from the security structure: any side. The structure is preferably A "flexible" which is not bendable and/or foldable, such as, for example, credit cards, ID cards, passports, banknotes, tickets, and other security documents. In the production of such a structure, when a mechanism has a limited method but it is considered that the level 2 verification is sufficient, verification can be performed, and the opacity can be observed only based on the permeation-predetermined form of electric radiation (for example, infrared and 'or ultraviolet light) illumination. Validated by the modified area. 156632. Doc 201228852 In addition, the existence of the opaque modified area can be hidden in the structure, thereby preventing the counterfeiter from discovering how to achieve structural replication, and in addition, since the first layer can have a reduced thickness in the opaque modified region Therefore, attempting to separate the first layer from at least one additional layer may cause damage to at least the opaque modified region. This can be easily identified by illumination of the illuminant, thereby providing additional tamper-proof beta opacity. The zone is preferably a zone of reduced opacity. Preferably, the region of reduced opacity is at least partially superimposed on the luminescent agent. The illuminant can be excited by at least one of ultraviolet light and infrared light. The illuminant can be disposed on a safety belt. In some embodiments, the seat belt can be positioned between at least one additional layer and the first material layer. The seat belt is preferably made of a fibrous material (preferably paper). The seat belt may have a surface area that is less than one surface area of at least one additional layer, thereby resulting in cost savings in structural manufacturing. In an exemplary embodiment of the present disclosure, the seat belt extends in a partial sense over only a portion of the surface area of at least one additional layer. In this case, the seat belt preferably extends over an area of at least one of the additional layers below the opacity-modified area of the first layer. In an exemplary embodiment, the opaque modified region is sufficiently transparent to allow illumination light to be transmitted through the first layer upon excitation of the luminescent agent. Specifically, when a region of reduced opacity is implemented, the region can have a maximum depth of from about 10% to about 90% of the thickness of the first layer. The area in which the opacity is modified may be a watermark and/or a pseudo watermark. The opacity of the opacity is preferably a region of reduced opacity. Watermark I56632. Doc, 6 - 201228852 is preferably a pale watermark having a recess on the side facing the first layer of at least one additional layer. For example, the pale watermark can be a screen printing watermark as disclosed in EP 1 122 36. When the opacity of the opaque modified area is increased, the document paper is sufficiently transparent that the characteristics of the opaque modified area appear (for example, a negative phase). The ''sigma structure' may comprise a laminated protective layer in contact with the first material layer. The first material layer may comprise a fibrous material, preferably paper. Additionally, at least one additional layer can include an opaque layer that is opaque over its entire surface area. The opaque modified area is only visible to the naked eye during luminescence excitation. The first layer and at least one additional layer may be joined together or the selected layers may be bonded to each other individually. For example, lamination may be performed using lamination. The first layer and the at least one additional layer are engageable such that an attempt is made to break away (for example by tearing) damage to the opaque modified area. This can provide evidence of tampering. At least the first layer preferably comprises a security paper. The weight of the paper can be, for example, in the range of 70 g/m 2 (g/m 2 ) to 18 〇 g/m 2 . A luminescent agent refers to a substance that emits light in response to an external stimulus/excitation. For example, the illuminant can respond to light stimulating emitted light (ie, photoluminescence), chemically stimulating emitted light (ie, chemiluminescence), electrically stimulating emitted light (ie, electroluminescent), and/or mechanically stimulating emitted light (ie, Frictional illumination). The luminescent agent is preferably one of photoluminescent agents in response to light stimuli, such as ultraviolet (UV) and/or infrared, and more specifically uv luminescent agents. The illuminating agent may comprise a luminescent ink, a luminescent fiber, a luminescent pigment, a illuminating flat security 7L piece (such as a "planchette") and a 156632. Doc 201228852 At least one of the luminescent adhesives. For example, when bonding the layers, the luminescent agent can be mixed with one of the adhesives used. For example, the illuminant can be mixed with an adhesive up to 50% by dry weight. The structure can include an electronic device at least partially disposed within at least one additional layer. The electronic device can be configured to provide information relating to at least one of the owners of the structure and structure. At least one additional layer can include a second layer and an intermediate layer. The electronic device can be, for example, an RFID device. Additionally, the electronic device can include an antenna that at least partially contacts the intermediate layer, the antenna being damaged by attempting to detach the first layer from the other bonding layer. This provides additional evidence of tampering. The electronic device can be at least partially disposed in the second layer. The illuminant can be disposed on the intermediate layer and/or within an intermediate material layer. The first layer and/or the at least one additional layer may comprise a compressible paper, for example, a paper such as that disclosed in European Patent Application No. EP 2 174 270. The structure is preferably a passport and includes a passport cover, the first layer and at least one additional layer being part of the reference cover. Additionally, the first layer of material may form one of the front or back pages of the protective cover. The first layer was originally a multi-page booklet. The file, which is then glued, for example, to at least one additional layer to form the front or back page of the protective cover. The excitation light can propagate through the opaque modified region to excite the luminescent agent. In another embodiment of the present disclosure, a fabrication as described above is provided. The method of construction. The method may comprise forming an opacity modified in the first material layer - Fτ, *^, and at least partially superimposing the opacity-modified region on at least a portion of the illuminant - Qiu Ba L丄 刀 knife, and bonding the first layer with At least one extra 156632. Doc 201228852 layer. The step ride can include lamination and/or can include applying an adhesive. The adhesive may comprise one or more luminescent agents. At least one additional layer of the material and the first layer can be fabricated at a different manufacturing location than the other layers. One area of opacity modified may be one designed to be etched or pressed into a fibrous layer during fabrication. For example, the opacity-modified region can be produced by creating a pulp layer on a cylinder paper machine that produces a reduced or increased thickness of the pulp layer. This is done in a forming wire of a round cage. A convex or concave impression is achieved. One area of opacity modification may also come from a pressured fiber layer that has been pressed against a platform Fourdrinier machine by means of a watermarking roller (which contains the opaque modified area of the embossed money). The zone in which this takes effect is simultaneously formed by pressing a specific area of the fiber layer in the wet portion of the machine and thereby extruding the water contained in the fiber. The opacity-modified region can be made in a fiber layer by mechanical and/or chemical means by applying a specific substance, and the design transparency is still visible. For example, an opaque modified region can be made by placing or printing a composition on a determined region of the fibrous layer, the composition modifying the transparency of the fibrous layer, particularly to provide a light region with a watermark And the dark areas and dark areas similar to the dark areas, without the result of being able to obtain precision and discoloration comparable to the precision and discoloration of a conventional watermark. For example, the fiber 156632 can be made by applying, for example, a substantially fat composition. Doc 201228852 The determined layer of the stratification layer makes the fiber layer more transparent, the composition making the fiber layer permanently more transparent, such as, for example, oil and transparent as described in U.S. Patent No. 2,211,141 A composition of one of the mineral material compositions' or a composition of one of the formulas described in U.S. Patent No. 1,479,337, incorporated herein by reference. A fluid-clearing composition can be polymerized by irradiation, as described in US Pat. No. 5,118,526, by heat transfer, as described in GB 1 489 084, or as DE 3 920 378 The fiber layer is made more transparent by the composition based on one of a polyether, an aliphatic isocyanate, and an ethanol applied by printing. ^ ^ A fibrous layer comprising a hot-melt material, such as, for example, the polyethylene described in EP 203 203 499, which undergoes a change in transparency under localized heat. The first fiber layer can be made more opaque without being made completely opaque to the illumination light, for example by applying an opacifying agent in the determined region to increase the opacity of the fibrous layer, as described in the patent application FR 2 353 676. For example, the opacifying agent can be a pigment or an aqueous suspension of one of the fillers or a chemical composition, a colored composition or a solution of one of the dyes. The agent can be applied to the first layer while the first layer is being formed and before the first layer is removed from the fabric such that the agent penetrates into the pores of the sheet and produces an opacity modification of the sheet after drying. Used to process in the selected area. The fabrication technique has the special need for a special rolling device for applying the agent, and the need to use a getter device to penetrate the pores of the sheet for better results. 156632.

This document describes a method of making a pseudo watermark on uncoated paper by applying a mark representing a pseudo watermark pattern against a piece of rewet paper with heat and pressure. One of the opacity modifications may be made on the uncoated paper by applying a rewet solution to one or more of the determined areas of the paper by heat and pressure to evaporate the solution in the determined area and densify the paper.

International Patent Application No. WO 97/Π493 also describes the production of coated paper comprising a pseudo watermark, the pseudo watermark being varied by the weight of the layer applied in the determined zone thereby producing a reduction or increase in the weight of the coating. Changes in thickness and opacity in these areas. International Patent Application No. 99/〇 14433 also describes the application of a wetting solution to at least one side of coated paper by Zhixing Bazhong on coated paper, or a plurality of determined areas and coated paper. Another method of making a pseudo watermark in the areas where pressure is applied and in which the solution is evaporated relative to the remainder of the paper and the coated paper is being processed (this method involves following the final coating operation = And make an image in paper after the dry coal step). Finally, as patent DE 1 71. >· π , 1 8 452 can be mechanically made opacity by mechanically embossing the embossed in the determined area of the fiber layer.

Doc -11· 201228852 Application WO 91/07285 describes printing a composition on a synthetic medium. The composition modifies the opacity of the support and comprises at least one mineral filler and at least one binder and a soluble or pigmentary colorant. The composition is applied in the determined zone and the entire surface of the media is then coated with a printable pigment composition using a coating method known to those skilled in the art. U.S. Patent No. 4,307,899 describes a verification card which comprises forming a print on a medium, preferably a plastic medium, by printing a partially superimposed colored layer. A region printed with a single layer looks light in transmitted light and appears dark in reflected light, and a region printed with a plurality of superimposed layers appears dark in transmitted light and looks light in reflected light, thereby generating A watermark effect. A multi-tone effect can be obtained by modifying the number of layers. One of the regions modified by opacity can also be made in a polymer layer by using a mechanical method. For example, as described in EP 0 655 3 16, a pseudo watermark can be made on a piece of polymer material by passing the sheet between two rollers, one of the rollers carrying one of the reliefs Or a convex pattern to form an imprint. The sheet is then oriented by stretching the sheet such that the pattern appears black and white in transmitted light' corresponding to the area marked as a protrusion or recess by the roller. International Patent Application No. WO 2007/016148 also describes a plastic layer suitable for deformation, in particular by stamping or embossing to form an image that appears to be a watermark and subsequently laminated without damaging the formed layer. image. In addition, one region of opacity modification can be made on a polymer layer by electromagnetic radiation (e.g., a laser). For example, the application EP 1 518 661 describes a specific area by electromagnetic radiation and by stretching a sheet 156632. Doc • 12-201228852 A method for producing a pseudo watermark on a roll of polymer sheet by presenting a stretched sheet corresponding to one of the transparent regions of the irradiated region. The opacity-modified region of the first layer can be made using any of the methods described above and/or any other method known in the art and not described herein. At least one additional layer may comprise a single layer or a plurality of layers. At least the additional layer can be a fibrous layer or can include one or more fibrous layers. For example, the fibrous layer can be based on cellulosic fibers (specifically cotton fibers) or synthetic fibers (such as, for example, polyamide) and/or polyester fibers. In particular, the middle layer can be half transparent tracing paper. The first layer and / or at least one additional layer may be a fiber or polymer layer.

Additional objects and advantages of the disclosure are set forth in the description which follows. The above summary, as well as the following detailed description, are intended to be illustrative and illustrative and not restrictive. [Embodiment] The present invention is incorporated in and constitutes a part of the specification of the present disclosure.

Reference will now be made in detail to the exemplary embodiments of the present disclosure. Wherever practicable, the same reference symbols are used in the drawings to refer to the same or similar parts. 1A through 1C are illustrations of a cross section of one of the security structures 1 consistent with embodiments of the present disclosure. As shown in Figure A, the security structure i can include a multi-page document, such as a passport, having a face 7 (having a front page and a back page) and pages 35 (also referred to as a "visa page"). Such passports may contain a data page that includes information relating to the passport holder and access to various other security features presented on the security structure 1. The first layer 4 comprises one or more regions 40 modified by opacity formed in accordance with the techniques described above, the opacity being modified to modify one or more of the regions 4 to any desired shape and size for a particular application. For example, the opacity modified area 40 can be shaped as one of the countries that issued one of the passport documents or can be identified as a particular shape associated with one of the security entities 1 issuing entity. Any desired number of opaque modified regions 40 may be provided on the first layer 4, wherein the opacity modified regions 4 〇 are at any desired location on the first layer 4. For example, it may be desirable to provide one or more zones 40 that are aligned to form a particular shape on the first layer 4, or that are opaque in a straight line or any other configuration. As shown, the opaque modified region 4 is preferably located on one of the bottom surfaces of the first layer 4 to face an intermediate layer 3〇. In other words, once assembled with other layers, the opacity-modified area 4〇 is inside one of the first layers 4 156632. Doc •15- 201228852 section. When the opaque modified region 40 is oriented in this manner, it does not appear on one of the surfaces of the first layer 4, thereby achieving additional hiding of the opaque modified region 40. It is desirable/independent that the opaque modified region 4 is sufficiently transparent that the illuminating light can be transmitted through the opaque modified region 40 during excitation of the luminescent agent 37. The first layer 4 is interfaced with the intermediate layer 30, which in turn is positioned between the first layer 4 and a second layer 6. The intermediate layer 3 can comprise any suitable material, as desired. For example, the intermediate layer 30 can comprise a fibrous material, a polymeric material, and/or any combination of materials. According to some embodiments and as illustrated in Figure 2, the intermediate layer 30 itself may comprise one or more layers of material. The layers comprising the intermediate layer 30 may be of similar or different materials, as desired. According to some embodiments, the intermediate layer 30 may comprise a compressible material, such as a compressible paper, such that additional elements may be added between the first layer 4 and the interlayer 30 and/or the intermediate layer 30 and/or second Layer 6 does not substantially increase one of the thicknesses associated with structure 1.

The paper material layer 3 〇 preferably comprises at least 15 percent by weight of synthetic fibers and/or at least in percent by weight. An existing nipple between 5 and 2 (such as acrylic acid vinegar). The paper requiring this composition is based on its association with the addition of other 7 elements, thereby off or eliminating the ability of the structure to increase with the addition of such elements. For example, to implement a seat belt 45 as described in more detail below, the intervening layer 30 of compressible material must be used. The intermediate layer 30 can be configured to have a surface area substantially similar to the first layer 4 having such length and width portions. This configuration makes 156632.

In accordance with some embodiments of the present disclosure, the intermediate layer 30 can include a luminescent agent 37 disposed on one surface of the intermediate layer 3 and/or interspersed throughout the thickness of the intermediate layer. For example, when the intermediate layer 3() comprises a fibrous material (e.g., paper), the luminescent agent 37 can be added to the furnish prior to forming on the screen and/or at any other suitable point in time during manufacture. In such embodiments, for example, as shown in Figure 1C, luminescent agent 37 can be present substantially throughout the surface of the intermediate layer. Alternatively, as shown in Fig. A, when the luminescent agent 37 is deposited on the intermediate layer 30, for example, a specific position is selected for this deposition based on the position of the opaque modified region. Preferably, the opaque modified region 40 is at least partially superimposed on the luminescent agent 37. The illuminant 37 may comprise, for example, a yellow luminescent pigment such as Lumilux 8D14® supplied by HONEYWELL. It may be desirable to provide a luminescent agent 37 for the fibers associated with at least some of the fibrous material itself. Alternatively, illuminant 37 may be applied to one surface of intermediate layer 30 after fabrication (e.g., forming or drying on a screen) or at any other suitable point as desired. 1B and 5 illustrate an illustration of an exemplary embodiment in which the illuminant 37 is associated with a security strip 45 as a supplement or replacement of the intermediate layer 30. The full strip 45 may include any suitable material. (for example, fibers, poly5 substances, etc.) and in particular luminescent agent 37. The illuminant 37 can spread the entire thickness of the seat belt 45 and/or be disposed on one or more surfaces of the seat belt 45. In such embodiments, the seat belt 45 is configured to be positioned between the first layer 4 and the intermediate layer 30 (e.g., in contact with both the first layer 4 and the intermediate layer 30) such that the 156632. Doc •17- 201228852 At least part of the full belt 45 is placed under at least part of the opaque modified area. The seat belt 45 has a surface area smaller than that of the first layer 4 and the intermediate layer 3〇. For example, in some embodiments, the seat belt 45 can have a surface area of 5% or less of the surface area associated with the first layer 4. According to some embodiments, the surface area of the seat belt 45 can be 25%, or 10% or even less of the surface area of the first layer 4. Since the illuminant is only present on the seat belt, this configuration can result in cost savings, at least for example, in the manufacture of a security structure. The seat belt 45 is implemented in conjunction with the intermediate layer 30 of compressible material, preferably at a location where the belt 45 is not perceived to increase in thickness. This helps to hide the security of the security structure 1 and further complicates its forgery. Although there is a method of including the illuminant 37 in a security structure 例如 (for example, an intermediate layer 3 〇, a safety belt 45, an adhesive between the first layer 4 and other portions of the cover 7 and the like), the illuminant 37 should be positioned. The opacity of at least a portion of the illuminant 37 placed on the first layer 4 is modified to modify one or more of the zones. In this manner, at least a portion of the illuminant 37 is positioned such that light passing through the first layer 4 (e.g., through the opaque modified region 4) impinges on the luminescent agent 37, thereby exciting the luminescent agent 3 7 And cause the emission of the illuminating light. The illuminant 3 7 produces illumination light propagation. The first layer is passed through to become observable and thereby clearly exhibit the characteristics of the opaque modified area (e.g., a design outline or a pattern). For example, as shown in FIG. 5, when a seat belt 45 is implemented, the seat belt 45 covers the intermediate layer 3 at a position such that the first layer 4 corresponds to the middle 156632. Doc •18· 201228852 When the layer 30 and the female full belt 45 are placed, the opacity-modified area 4〇 covers the safety belt 45. Similarly, when the seat belt 45 is not implemented, the illuminant 3 7 may be present on the intermediate layer 30 and/or in a position associated with the opaque modified region of the first layer 4. The intermediate layer 30 can include one or more cavities 52 that enable insertion of at least a portion of the electronic device 17. These cavities 52 may include one or more of the through holes or a blind hole adapted to receive all or part of the electronic device 17. For example, as shown in Fig. 4, a through hole may be formed in the intermediate layer 30, and a portion of the electronic device 17 may be at least partially inserted into the through hole in the intermediate layer 3''. According to some embodiments, as shown in Fig. 3B, a recess 53 may be formed in the intermediate layer 30, the recess 53 being configured to receive an electronic device 17. In still other embodiments, a recess may be present in both the second layer 6 and the intermediate layer 30 such that the layers may receive a portion of the electronic device 17. Many such configurations can be used as needed to result in a security structure as described herein without departing from the scope of the present disclosure. The electronic device 17 may comprise any suitable device that implements a level 2 verification of the security structure. For example, an electronic device 17A can include an electronic wafer that constitutes an RFID device. The electronic device 17 can carry its own antenna or an antenna intended to be coupled to an amplifying antenna carried by the inlay. An antenna 64 associated with the electronic device 17 can be placed on and/or within portions of the intermediate layer 3, the second layer, or other layers present within the security structure. For example, as shown in FIG. 4, after inserting the electronic device 17, but before the intermediate layer 30 and the second layer 6 are provided, it may be necessary to fix the antenna 64 to the intermediate layer 30 so that when the layers are joined, the antenna 64 is also Is fixed in the safety structure i 156632. Doc •19· 201228852. As shown, the second layer 6 can be limited to one of the opaque outer layers 9 of the passport cover. For example, the additional layer 9 can be a polymeric strengthening layer. The first layer 6 can comprise a fiber and/or polymeric material and can be woven, non-woven or any combination thereof. In some embodiments, as shown in Figures 3A, 3C, and 4, the second layer 6 can also include one or more cavities 58 configured to receive a portion of the electronic device ^ 7 ^, for example, A via or a blind via may be provided in the second layer 6 to facilitate receipt of at least a portion of the electronic device 17. In some embodiments, the electronic device 17 can be located substantially away from the opaque modified region 40 and the luminescent agent 37. Alternatively, for example, when space is limited, the electronic device 17 can be located in a region (10) that is relatively close to the opacity modified region and that can be partially modified by the opacity. Additionally, the electronic device 17 can be adhered to one or more layers by way of example of an adhesive. These techniques allow the electronic device 17 to be installed at many points during the construction of the security structure. According to an embodiment of the present disclosure, the first layer 4 is fixed relative to the second layer 6, and the intermediate layer 30 such that an attempt is made to separate the first layer 4, the second layer 6, and/or the intermediate layer 30 from each other at least for opacity The modified area causes damage (e.g., tearing due to reduced thickness on the opaque modified area 40), and thus indicates tampering. The layer 4, the first layer 6, and/or the intermediate layer 3 may be achieved, for example, by lamination or other suitable process that results in a fixed alignment of the first layer 4, the second layer 6, and the intermediate layer 30. fixed. According to some embodiments, the introduction of an adhesive between the layers results in a first layer 4, a medium of 56632. Doc •20· 201228852 Interlayer 30, and the joint between each of the second layer 6. According to these embodiments' and when the seat belt 45 is implemented, the adhesive also causes engagement between the seat belt 45 and the first layer 4 and the intermediate layer 6. Light is prevented from transmitting through the security structure 1 at least in the region surrounding the opaque modified region 40. Although light may be transmitted through other areas of the security structure 1 (eg, where there are other security features at a distance from the area of reduced opacity), the opacity modified area 4 and its associated The features are not observable in light transmitted through either side of the security structure 1 (i.e., any light emitted other than the illuminant 37). For example, one of the security structures 1 as described above does not reveal the opaque warped region 40 in ambient transmitted light. But 'when the first layer 4 of the security structure 1 is placed such that the light that causes the illuminant 4 to excite (by transmissive through the opaque modified region 4〇) impinges on the luminescent agent 37, the luminescent agent 37 will be excited. Thereby, the light re-emitted by the illuminant 37 allows the opacity-modified region to be observed. As shown in FIG. 5, the security structure exposed to light via the first layer 4 (e.g., a passport) is modified when the illuminant 37 associated with the seat belt 45 is exposed to illuminate the cover tape 45 based on the excitation of the emitted light. One of the 4 图案 patterns. When the female full structure 1 is a passport, the outer side of the cover layer 9 prevents light from transmitting through any portion of the security structure 1, except for the light emitted by the illuminant 37 and transmitted through the first layer. 4 light outside. 6 is a flow chart illustrating a method for fabricating a security structure consistent with embodiments of the present disclosure. An opacity modified zone 40 is formed in and/or on the first layer 4 (step 605). The opacity modified region 40 can be formed during or after the formation of the first layer 4. 156632. Doc - 21 - 201228852 The first layer 4 is then aligned (e.g., superimposed) with at least one additional layer such that at least a portion of the luminescent agent 37 is placed under the first layer 4 (step 61 〇). By way of example, the illuminant can be associated with a seat belt 45 and/or an intermediate layer 3A. The insertion of an electronic device 17, if any, can be performed at any point during the assembly of the security structure (for example during the manufacture of the inlay) and can occur at a manufacturing location different from the manufacturing location of the first layer 4. Engagement of the intermediate layer 3 and the safety belt 45 (if present) may be performed between the first layer 4 and the second layer 6 (step 620). For example, the bonding can be performed by lamination. 7 is an illustrative flow diagram of one method for verifying a security structure in accordance with an embodiment of the present disclosure. The user can first illuminate the first layer 4 with a violet and/or infrared light (step 705). The user can then inspect the document to determine whether the opaque modified region 40 and/or its features are visible via illumination light from the excitation of the illuminant 37. Although the disclosure describes light as impinging on the first layer 4 In order to excite the illuminant 3 7 'in some embodiments, a waveguide for guiding light from the edge of the security structure 1 to the region in which the illuminant 37 is present may be introduced. In this manner, the opacity-modified region 40 becomes visible when light from the waveguide impinges on the luminescent agent 37. In addition, although the reduced embodiment has been generally described with reference to a region having opacity with reduced opacity, according to some embodiments not shown, one region of opacity modified may have an increase. transparency. In other words, the region of the first layer 4 can have additional material deposited on the first layer 4 thereby creating a "dark watermark". In these embodiments, an example is 156632. Doc -22· 201228852 ll, when the illuminant 37 has been provided on the entire surface of one of the intermediate layers 30, the excitation light can pass through the surrounding portion of the first layer 4 to impinge on the luminescent agent 37, resulting in emission of the illuminating light. . The emitted illumination light then passes through the first layer and can then be characterized by the dark watermark of (4); for example, the watermark wheel (4) becomes a daily request, not a document paper (rather than having a document paper larger than the document paper) The thicker area of the dark watermark of the thickness is transparent to the illumination light. The structure fabricated in accordance with an embodiment of the present disclosure enables at least a visual verification and at the expense of electronic verification based on electronic methods. When electronic methods are not available ‘depending solely on the level of complexity associated with visual verification devices, an organization can still use visual verification to determine the authenticity of a document.
