於個人電腦、行動設備終端(PDA)、遊戲機、電視(TV)、汽車導航系統、觸控面板、手寫板等的圖像顯示裝置、例如電漿顯示器(PDP)、液晶顯示器(LCD)、有機EL顯示器(OLED)、無機EL顯示器、電泳顯示器(EPD)、干擾調變顯示器(IMOD)等平面型或使用具有曲面之圖像顯示面板之圖像顯示裝置中,為了確保視認性或防止破損等,未於各構成構件間設置空隙並利用黏著片材或液狀黏著劑將各構成物材間貼合而一體化。 例如,於具備於液晶模組之視認側與表面保護面板之間***有觸控面板而成之構成之圖像顯示裝置中,於表面保護面板與液晶模組之視認側之間配置黏著片材或液狀黏著劑,將觸控面板與另一構成構件、例如將觸控面板與液晶模組、觸控面板與表面保護面板貼合而一體化。 觸控面板通常具備由摻錫之氧化銦(ITO)、銦-鎵-鋅複合氧化物(IGZO)、摻Ga之氧化鋅(GZO)等金屬氧化物或銀、銅、鉬等金屬材料形成之微細配線或具有由銀奈米線、奈米碳管等形成之透明導電層之上部電極板及下部電極板。又,為了彙集透明導電層所檢測出之手指或觸摸筆等之位置資訊並進行通信,將由金屬材料形成之導體圖案(配線圖案)形成於透明導電層與IC(Integrated Circuit,積體電路)等控制機構之間。該等由各種材料形成之透明導電層或導體圖案通常係以表面與黏著劑相接之方式固定。該透明導電層或導體圖案存在如下顧慮:對腐蝕脆弱,於高溫或濕熱環境下會因黏著材之釋氣或源自溶出成分之酸成分等而腐蝕,視情形會斷線等。 因此,例如於專利文獻1中揭示有含有苯并***及/或其衍生物作為金屬腐蝕防止劑之金屬貼附用黏著片材。 又,例如於專利文獻2中揭示有如下黏著劑組合物:其包含將丙烯酸烷氧基烷基酯及具有可交聯之官能基之丙烯酸系單體作為必需成分而構成之丙烯酸系聚合物及交聯劑,並且丙烯酸系聚合物中實質上不包含含羧基單體。揭示有根據該黏著劑組合物,藉由使用特定量之脂肪族系異氰酸酯交聯劑及含有複數個羥基之胺系化合物而抑制黃變,又,藉由使丙烯酸系聚合物採用交聯結構,即便不包含含羧基單體成分,亦可滿足高溫下之耐發泡、剝落性。 [先前技術文獻] [專利文獻] [專利文獻1]日本專利特開2006-45315號公報 [專利文獻2]日本專利特開2009-079203號公報Image display devices such as a personal computer, a mobile device terminal (PDA), a game machine, a television (TV), a car navigation system, a touch panel, a tablet, etc., such as a plasma display (PDP), a liquid crystal display (LCD), In order to ensure visibility or prevent breakage in an image display device such as an organic EL display (OLED), an inorganic EL display, an electrophoretic display (EPD), an interference modulation display (IMOD), or an image display device having a curved surface display panel For example, voids are not provided between the respective constituent members, and the respective constituent materials are bonded and integrated by an adhesive sheet or a liquid adhesive. For example, in an image display device having a touch panel formed between a viewing side of a liquid crystal module and a surface protection panel, an adhesive sheet is disposed between the surface protection panel and the viewing side of the liquid crystal module. Or a liquid adhesive, the touch panel and the other constituent members, for example, the touch panel and the liquid crystal module, the touch panel and the surface protection panel are integrated and integrated. The touch panel is usually formed of a metal oxide such as tin-doped indium oxide (ITO), indium-gallium-zinc composite oxide (IGZO), Ga-doped zinc oxide (GZO), or a metal material such as silver, copper or molybdenum. The fine wiring or the upper electrode plate and the lower electrode plate of the transparent conductive layer formed of a silver nanowire, a carbon nanotube or the like. In addition, in order to collect and communicate the position information of a finger or a touch pen detected by the transparent conductive layer, a conductor pattern (wiring pattern) formed of a metal material is formed on the transparent conductive layer and an integrated circuit such as an IC (integrated circuit). Between control agencies. The transparent conductive layer or conductor pattern formed of various materials is usually fixed in such a manner that the surface is in contact with the adhesive. The transparent conductive layer or the conductor pattern has the following disadvantages: it is fragile to corrosion, and is corroded by the outgas of the adhesive material or the acid component derived from the eluted component in a high-temperature or moist heat environment, and may be broken as the case may be. For example, Patent Document 1 discloses an adhesive sheet for metal attaching containing benzotriazole and/or a derivative thereof as a metal corrosion preventing agent. Further, for example, Patent Document 2 discloses an adhesive composition comprising an acrylic polymer comprising an alkoxyalkyl acrylate and an acrylic monomer having a crosslinkable functional group as an essential component, and A crosslinking agent, and the acrylic polymer does not substantially contain a carboxyl group-containing monomer. It is disclosed that, according to the adhesive composition, yellowing is inhibited by using a specific amount of an aliphatic isocyanate crosslinking agent and an amine compound containing a plurality of hydroxyl groups, and by using a crosslinked structure of the acrylic polymer, Even if it does not contain a carboxyl group-containing monomer component, it can satisfy foaming and peeling resistance at high temperatures.

[發明所欲解決之問題] 用於圖像顯示裝置之構成構件包含於高溫或高濕環境下經時產生氣體(亦稱為「釋氣」)之構件,故而於利用黏著片材貼合該等圖像顯示裝置之構成構件之情形時,該黏著片材亦需要具有可充分地對抗釋氣之氣壓之耐發泡可靠性。 上述專利文獻1之含有金屬腐蝕防止劑之兩面黏著片材存在金屬腐蝕防止劑於照射紫外線之耐久性試驗中發泡而使光學特性降低等問題點。 根據上述專利文獻2之黏著劑組合物,即便為不包含丙烯酸等含羧基單體之丙烯酸系聚合物,亦可滿足高溫下之耐發泡、剝落性,但由於無法防止作為腐蝕之因素之水分滲入至黏著劑中,故而就金屬腐蝕防止性之觀點而言,未必滿足。 因此,本發明所欲解決之問題在於提供一種不會腐蝕導電構件且具有耐發泡可靠性及良好之硬化特性之導電構件用黏著片材。更具體而言,提供一種即便與透明導電層之導電層面或由金屬材料形成之導體圖案(配線圖案)直接貼合,亦不會腐蝕該等,又,即便隔著絕緣保護膜(鈍化膜)與透明導電層之導電層面貼合,亦不會腐蝕透明導電層之導電構件用黏著片材。 [解決問題之技術手段] 本發明之主要特徵在於具有包含含有(甲基)丙烯酸系共聚物及1,2,3-***之黏著劑組合物之黏著劑層。 [發明之效果] 本發明之導電構件用黏著片材可具有針對導電構件之耐腐蝕可靠性,並且亦可具有作為黏著片材之耐發泡可靠性及良好之硬化特性。因此,本發明之導電構件用黏著片材可用作適合貼合具有透明導電層及/或由包含銅或者銀之金屬材料形成之導體圖案之導電構件等各種導電構件。尤其可較佳地用作具有觸控面板之圖像顯示裝置用之黏著片材。[Problems to be Solved by the Invention] The constituent members for the image display device include members that generate gas (also referred to as "gassing") over time in a high-temperature or high-humidity environment, and thus are bonded to each other by using an adhesive sheet. In the case of a constituent member of an image display device, the adhesive sheet is also required to have a foaming reliability which is sufficiently resistant to the gas pressure of the outgassing. In the double-sided adhesive sheet containing the metal corrosion preventing agent of the above-mentioned Patent Document 1, there is a problem that the metal corrosion preventing agent is foamed in the durability test against ultraviolet rays to lower the optical characteristics. According to the adhesive composition of the above-mentioned Patent Document 2, even if it is an acrylic polymer which does not contain a carboxyl group-containing monomer such as acrylic acid, it can satisfy the foaming resistance and peeling property at a high temperature, but it cannot prevent moisture as a factor of corrosion. Since it penetrates into an adhesive, it is not necessarily satisfying from the viewpoint of metal corrosion prevention. Therefore, the problem to be solved by the present invention is to provide an adhesive sheet for a conductive member which does not corrode a conductive member and which has foaming reliability and good hardening properties. More specifically, it is provided that even if it is directly bonded to a conductive layer of a transparent conductive layer or a conductor pattern (wiring pattern) formed of a metal material, it does not corrode, and even if an insulating protective film (passivation film) is interposed therebetween Adhesive sheet for conductive members that adheres to the conductive layer of the transparent conductive layer and does not corrode the transparent conductive layer. [Technical means for solving the problem] The main feature of the present invention resides in an adhesive layer comprising an adhesive composition containing a (meth)acrylic copolymer and 1,2,3-triazole. [Effects of the Invention] The adhesive sheet for a conductive member of the present invention can have corrosion resistance reliability with respect to the conductive member, and can also have foaming reliability and good hardening characteristics as an adhesive sheet. Therefore, the adhesive sheet for a conductive member of the present invention can be used as various conductive members suitable for bonding a conductive member having a transparent conductive layer and/or a conductor pattern formed of a metal material containing copper or silver. In particular, it can be preferably used as an adhesive sheet for an image display device having a touch panel.

於欲獲得凝集力較高之黏著組合物之情形時,就分子量越大,越可藉由分子鏈之交聯而獲得凝集力之觀點而言,(甲基)丙烯酸系(共)聚合物之質量平均分子量較佳為70萬以上且150萬以下,尤佳為80萬以上或者130萬以下。另一方面,於欲獲得流動性或應力緩和性較高之黏著組合物之情形時,質量平均分子量較佳為10萬以上且70萬以下,尤佳為15萬以上或者60萬以下。 另一方面,於使黏著片材等成形時不使用溶劑之情形時,由於不易使用分子量較大之聚合物,故而(甲基)丙烯酸系(共)聚合物之質量平均分子量較佳為10萬以上且70萬以下,尤佳為15萬以上或者60萬以下,其中,尤佳為20萬以上或者50萬以下。 (金屬腐蝕防止劑) 本組合物含有1,2,3-***。 1,2,3-***具有作為對導電構件之導電層之金屬腐蝕防止劑之功能。1,2,3-***由於對銅之耐銅腐蝕可靠性及作為黏著片材之耐發泡可靠性優異,因此含有1,2,3-***之本組合物可較佳地用作具有透明導電層及由包含銅之金屬材料形成之導體圖案(配線圖案)之導電構件。其原因在於推測藉由於由包含銅之金屬材料形成之導體圖案表面形成銅原子與1,2,3-***之分子化學鍵結而成之保護皮膜而防止腐蝕。又,於具有由包含銀之金屬材料形成之導體圖案之導電構件中,亦可同樣地實現利用1,2,3-***所得之保護皮膜之效果。 再者,存在1,2,4-***作為1,2,3-***之異構物。該1,2,4-***係熔點約為120℃之固體,另一方面,1,2,3-***之熔點約為20℃,於室溫下大致為液體狀態。因此,1,2,3-***具有混合於黏著劑組合物中時之分散性優異而可均勻地混合,又,容易母料化等優異之優勢。 於本組合物中,就金屬腐蝕防止劑之滲出或金屬腐蝕防止效果等觀點而言,較佳為以相對於(甲基)丙烯酸系(共)聚合物100質量份為0.01質量份以上且5質量份以下之比率含有1,2,3-***,其中,進一步較佳為以0.1質量份以上或者1質量份以下之比率含有1,2,3-***,其中,進一步較佳為以0.2質量份以上或者0.5質量份以下之比率含有1,2,3-***。 再者,本組合物中亦可將1,2,3-***與1,2,4-***併用。 (亞磷酸酯化合物) 本組合物可進而含有亞磷酸酯化合物。 亞磷酸酯化合物不僅其本身不具有腐蝕性,而且亦可使羧基等酸成分穩定。因此,藉由於包含特定之(甲基)丙烯酸系(共)聚合物之本組合物中調配亞磷酸酯化合物,即便本組合物包含酸成分,亦可防止作為被黏著體之導電構件之氧化劣化,於本組合物不包含酸成分之情形時,當然可防止作為被黏著體之導電構件之氧化劣化。 因此,若由含有亞磷酸酯化合物之本組合物形成黏著片材,則可具有對導電構件(典型而言,具有包含ITO之透明導電層及/或由包含銅或銀之金屬材料形成之導體圖案之導電構件)之耐腐蝕可靠性,並且可防止導電構件之氧化劣化。因此,例如可較佳地用作具有觸控面板之圖像顯示裝置用之黏著片材。 本組合物可含有之亞磷酸酯化合物並無限定。尤其較佳為下述式(1)所示之亞磷酸酯化合物。 式(1)      P[-OR]3

其中,作為本組合物所含有之亞磷酸酯化合物,例如若考慮到與本組合物之相溶性,則較佳為脂肪族亞磷酸酯(例如,作為實施例2-2之亞磷酸酯化合物之亞磷酸三癸酯或實施例2-3之3,9-雙(癸氧基)-2,4,8,10-四氧雜-3,9-二磷雜螺[5.5]十一烷等)。又,若考慮到耐水解性,則較佳為芳香族亞磷酸酯(例如,作為實施例2-1之亞磷酸酯化合物之亞磷酸三(2,4-二第三丁基苯基)酯等)。又,若考慮到溶解性與耐水解性之平衡性,則較佳為亞磷酸二苯酯單(十三烷基)酯等兼具脂肪族酯基與芳香族酯基之亞磷酸酯。 於本組合物中,關於亞磷酸酯化合物之含有比率,就無損黏著性能且可更有效地抑制ITO等之導電構件之氧化劣化之觀點而言,較佳為以相對於(甲基)丙烯酸系(共)聚合物100質量份為0.0001(1×10-4 )質量份以上且2.0質量份以下之比率含有亞磷酸酯化合物,其中,進一步較佳為以0.0005質量份以上或者0.8質量份以下之比率含有亞磷酸酯化合物,其中,進一步較佳為以0.001質量份以上或者0.7質量份以下之比率含有亞磷酸酯化合物,尤其進一步較佳為以0.01質量份以上或者0.6質量份以下之比率含有亞磷酸酯化合物。 (其他金屬腐蝕防止劑) 於本組合物中,除1,2,3-***及亞磷酸酯化合物以外,亦可併用1,2,4-***、苯并***及其衍生物等其他金屬腐蝕防止劑。 (交聯劑) 本組合物亦可視需要包含交聯劑。 例如,作為使上述(甲基)丙烯酸系(共)聚合物進行交聯之方法,可列舉:添加可與導入至(甲基)丙烯酸系(共)聚合物中之羥基或羧基等反應性基化學鍵結之交聯劑,並藉由加熱或熟化使之反應之方法;或添加作為交聯劑之具有2個以上之(甲基)丙烯醯基之多官能(甲基)丙烯酸酯及光聚合起始劑等反應起始劑,並藉由紫外線照射等使之交聯之方法。其中,就不會因反應而消耗本組合物中之羧基等極性官能基而可維持源自極性成分之較高之凝集力或黏著物性之觀點而言,較佳為藉由紫外線等光照射之交聯方法。 作為上述交聯劑,例如可列舉具有選自(甲基)丙烯醯基、環氧基、異氰酸酯基、羧基、羥基、碳二醯亞胺基、㗁唑啉基、氮丙啶基、乙烯基、胺基、亞胺基、醯胺基、N-取代(甲基)丙烯醯胺基、烷氧基矽烷基中之至少1種交聯性官能基之交聯劑,可使用1種,或亦可將2種以上組合使用。再者,交聯性官能基亦可由可脫保護之保護基保護。 其中,就交聯反應之控制之容易性之觀點而言,較佳為多官能(甲基)丙烯酸酯。 作為此種多官能(甲基)丙烯酸酯,例如可列舉:1,4-丁二醇二(甲基)丙烯酸酯、1,6-己二醇二(甲基)丙烯酸酯、1,9-壬二醇二(甲基)丙烯酸酯、聚伸烷基二醇二(甲基)丙烯酸酯、新戊二醇二(甲基)丙烯酸酯、甘油二(甲基)丙烯酸酯、季戊四醇三(甲基)丙烯酸酯、季戊四醇四(甲基)丙烯酸酯、二季戊四醇六(甲基)丙烯酸酯、三季戊四醇五(甲基)丙烯酸酯、三羥甲基丙烷三(甲基)丙烯酸酯、異氰尿酸三(丙烯醯氧基乙基)酯等紫外線硬化型之多官能單體類,以及聚酯(甲基)丙烯酸酯、環氧(甲基)丙烯酸酯、(甲基)丙烯酸胺基甲酸酯、聚醚(甲基)丙烯酸酯等多官能丙烯酸系低聚物類或多官能丙烯醯胺等。 又,作為具有2種以上之交聯性官能基之交聯劑,例如可列舉:(甲基)丙烯酸縮水甘油酯、α-乙基丙烯酸縮水甘油酯、(甲基)丙烯酸-3,4-環氧丁酯、4-羥基丁基(甲基)丙烯酸酯縮水甘油醚等含環氧基單體;(甲基)丙烯酸2-異氰酸酯基乙酯、異氰酸2-(2-(甲基)丙烯醯氧基乙氧基)乙酯、(甲基)丙烯酸2-(0-[1'-甲基亞丙基胺基]羧基胺基)乙酯、(甲基)丙烯酸2-[(3,5-二甲基吡唑基)羰基胺基]乙酯等含異氰酸酯基或封端異氰酸酯基之單體;乙烯基三甲氧基矽烷、乙烯基三乙氧基矽烷、3-縮水甘油氧基丙基三甲氧基矽烷、3-(甲基)丙烯醯氧基丙基甲基二乙氧基矽烷、3-(甲基)丙烯醯氧基丙基三乙氧基矽烷、N-2-(胺基乙基)-3-胺基丙基甲基二甲氧基矽烷、3-異氰酸酯基丙基三乙氧基矽烷等各種矽烷偶合劑。 具有2種以上之交聯性官能基之交聯劑亦可採用使一官能基與(甲基)丙烯酸系(共)聚合物反應而鍵結於(甲基)丙烯酸系(共)聚合物所成之結構。藉由採用此種結構,可使例如(甲基)丙烯醯基或乙烯基等雙鍵性之交聯性官能基化學鍵結於(甲基)丙烯酸系(共)聚合物。又,藉由使交聯劑鍵結於(甲基)丙烯酸系(共)聚合物,有可抑制交聯劑之滲出或本黏著片材之意外之塑化之傾向。又,藉由使交聯劑鍵結於(甲基)丙烯酸系(共)聚合物而促進光交聯反應之反應效率,因此有可獲得凝集力更高之硬化物之傾向。 本組合物亦可進而含有可與交聯劑之交聯性官能基反應之單官能單體。作為此種單官能單體,例如可列舉:丙烯酸甲酯等(甲基)丙烯酸烷基酯;(甲基)丙烯酸羥乙酯、(甲基)丙烯酸羥丙酯、(甲基)丙烯酸羥丁酯、聚伸烷基二醇(甲基)丙烯酸酯等含羥基(甲基)丙烯酸酯;(甲基)丙烯酸、2-(甲基)丙烯醯氧基乙基六氫鄰苯二甲酸、2-(甲基)丙烯醯氧基丙基六氫鄰苯二甲酸、2-(甲基)丙烯醯氧基乙基鄰苯二甲酸、2-(甲基)丙烯醯氧基乙基順丁烯二酸、2-(甲基)丙烯醯氧基丙基順丁烯二酸、2-(甲基)丙烯醯氧基乙基琥珀酸、2-(甲基)丙烯醯氧基丙基琥珀酸、丁烯酸、反丁烯二酸、順丁烯二酸、伊康酸等含羧基單體;順丁烯二酸酐、伊康酸酐等含酸酐基單體;(甲基)丙烯酸四氫糠酯、甲氧基聚乙二醇(甲基)丙烯酸酯等含醚基(甲基)丙烯酸酯;(甲基)丙烯醯胺、二甲基(甲基)丙烯醯胺、二乙基(甲基)丙烯醯胺、(甲基)丙烯醯基嗎啉、異丙基(甲基)丙烯醯胺、二甲胺基丙基(甲基)丙烯醯胺、苯基(甲基)丙烯醯胺、N-甲氧基甲基(甲基)丙烯醯胺、N-丁氧基甲基(甲基)丙烯醯胺等(甲基)丙烯醯胺系單體等。 其中,就提高對被黏著體之密接性或濕熱白化抑制之效果之觀點而言,較佳為使用含羥基(甲基)丙烯酸酯或(甲基)丙烯醯胺系單體。 關於交聯劑之含量,就使本組合物之柔軟性與凝集力平衡之觀點而言,較佳為以相對於上述(甲基)丙烯酸系(共)聚合物100質量份而為0.01以上且10質量份以下之比率調配,其中,尤佳為0.05質量份以上或者8質量份以下,其中,尤佳為0.1質量份以上或者5質量份以下。 再者,於本黏著片材為多層之情形時,關於構成黏著片材之層中之中間層或成為基材之層,交聯劑之含量亦可超過上述範圍。中間層或成為基材之層中之交聯劑之含量較佳為以相對於上述(甲基)丙烯酸系(共)聚合物100質量份而為0.01以上且40質量份以下之比率調配,其中,尤佳為1質量份以上或者30質量份以下,其中,尤佳為2質量份以上或者25質量份以下。 (光聚合起始劑) 於藉由光照射進行交聯之情形時,較佳為含有光聚合起始劑。 基於光聚合起始劑之自由基產生機構被分為2大類,有將自身之單鍵裂解並分解而產生自由基之α裂解型、及自系統中之化合物中使氫激發而產生自由基之脫氫型。該等之中,較佳為使用脫氫型光交聯起始劑。 其中,於使用具有(甲基)丙烯醯基之有機系交聯劑作為交聯劑之情形時,尤佳為進而添加光聚合起始劑。原因在於藉由光照射產生自由基而成為系統中之聚合反應之起點。 光聚合起始劑可適當使用目前公知者。其中,就交聯反應之控制之容易性之觀點而言,較佳為感應到波長380 nm以下之紫外線之光聚合起始劑。 另一方面,就可獲得較高之光反應性之方面及所感應之光容易到達至本黏著片材之深部之方面而言,較佳為感應到長於波長380 nm之波長之光之光聚合起始劑。 光聚合起始劑根據自由基產生機構而被分成2大類,大致分成可將光聚合起始劑自身之單鍵裂解分解而產生自由基之裂解型光聚合起始劑、及經光激發之起始劑與系統中之氫供與體形成激發錯合物並可使氫供與體之氫轉移之脫氫型光聚合起始劑。 該等中之裂解型光聚合起始劑於藉由光照射產生自由基時會分解而成為另一化合物,一旦被激發,則會失去作為交聯起始劑之功能。因此,不會以活性種之形式殘存於交聯反應結束後之黏著材中,從而不可能使黏著材產生意外之光劣化等,故而較佳。 另一方面,脫氫型光聚合起始劑於藉由紫外線等活性能量線照射產生自由基之反應時,不會產生如裂解型光聚合起始劑之分解物,因此就反應結束後不易成為揮發成分,從而可降低對被黏著體之損傷之方面而言有用。 作為上述裂解型光聚合起始劑,就對光之感應性較高且反應後成為分解物並脫色之方面而言,較佳為雙(2,4,6-三甲基苯甲醯基)-苯基氧化膦、2,4,6-三甲基苯甲醯基二苯基氧化膦、(2,4,6-三甲基苯甲醯基)乙氧基苯基氧化膦、雙(2,6-二甲氧基苯甲醯基)2,4,4-三甲基戊基氧化膦等醯基氧化膦系光聚合起始劑。 作為上述脫氫型光聚合起始劑,例如可列舉:二苯甲酮、4-甲基-二苯甲酮、2,4,6-三甲基二苯甲酮、4-苯基二苯甲酮、3,3'-二甲基-4-甲氧基二苯甲酮、4-(甲基)丙烯醯氧基二苯甲酮、4-[2-((甲基)丙烯醯氧基)乙氧基]二苯甲酮、4-(甲基)丙烯醯氧基-4'-甲氧基二苯甲酮、2-苯甲醯苯甲酸甲酯、苯甲醯甲酸甲酯、二乙二醇雙(2-苯基-2-側氧基乙酸酯)、4-(1,3-丙烯醯基-1,4,7,10,13-五氧雜十三烷基)二苯甲酮、9-氧硫&#134079;□、2-氯-9-氧硫&#134079;□、3-甲基-9-氧硫&#134079;□、2,4-二甲基-9-氧硫&#134079;□蒽醌、2-甲基蒽醌、2-乙基蒽醌、2-第三丁基蒽醌、2-胺基蒽醌、樟腦醌或其衍生物等。 該等之中,較佳為二苯甲酮、4-甲基-二苯甲酮、2,4,6-三甲基二苯甲酮、4-苯基二苯甲酮、3,3'-二甲基-4-甲氧基二苯甲酮、4-(甲基)丙烯醯氧基二苯甲酮、4-[2-((甲基)丙烯醯氧基)乙氧基]二苯甲酮、4-(甲基)丙烯醯氧基-4'-甲氧基二苯甲酮、2-苯甲醯苯甲酸甲基、苯甲醯基甲酸甲基。 再者,上述所列舉之光聚合起始劑既可使用任1種或其衍生物,亦可將該等之2種以上組合使用。 進而,除光聚合起始劑以外,亦可使用增感劑。作為增感劑,並無特別限定,只要為光聚合起始劑所使用之增感劑,則可無問題地使用。例如可列舉:芳香族胺或蒽衍生物、蒽醌衍生物、香豆素衍生物、9-氧硫□衍生物、酞菁衍生物等或二苯甲酮、&#134079;酮、9-氧硫&#134079;□、米其勒酮、9,10-菲醌等芳香族酮及該等之衍生物等。 再者,光聚合起始劑或增感劑亦可以鍵結於(甲基)丙烯酸系(共)聚合物之狀態包含。作為使光聚合起始劑或增感劑鍵結於(甲基)丙烯酸系(共)聚合物之方法,可採用與使上述交聯劑鍵結於(甲基)丙烯酸系(共)聚合物之情形時相同之方法。

本黏著片材具有對導電構件、尤其是透明導電層或由包含銅之金屬材料形成之導體圖案之防腐性。因此,可將利用以下之(1)~(2)之方法所測得之ITO電阻值之變化率[((Ω/Ω0)-1)×100]設為未達5%,其中,可設為未達3%。又,可將利用以下之(3)~(4)之方法所測得之銅電阻值之變化率[((Ω/Ω0)-1)×100]設為未達20%,其中,可設為未達10%,進而可設為未達5%,尤其可設為未達3%。 (1)將導電構件用黏著劑組合物(本組合物)製膜成厚度150 μm之片狀而製成黏著片材,並將上述黏著片材貼合於包含氧化銦(ITO)之ITO配線形成於玻璃基板上而成之評價用ITO玻璃基板而製作附黏著片材之ITO配線。 (2)預先測定上述附黏著片材之ITO配線中之ITO配線之室溫下之電阻值(Ω0),並於65℃・90%RH環境下將上述附黏著片材之ITO配線保管500小時,測定上述附黏著片材之ITO配線中之ITO配線之上述保管後之電阻值(Ω)。 (3)將導電構件用黏著劑組合物(本組合物)製膜成厚度150 μm之片狀而製成黏著片材,並將上述黏著片材貼合於銅配線形成於玻璃基板上而成之評價用銅玻璃基板而製作附黏著片材之銅配線。 (4)預先測定上述附黏著片材之銅配線中之銅配線之室溫下之電阻值(Ω0),並於65℃・90%RH環境下將上述附黏著片材之銅配線保管500小時,測定上述附黏著片材之銅配線中之銅配線之上述保管後之電阻值(Ω)。 (透明性) 本黏著片材較佳為光學透明。即,較佳為透明黏著片材。此處,所謂「光學透明」,意在總光線透過率為80%以上,較佳為85%以上,更佳為90%以上。 (厚度) 本黏著片材之厚度較佳為10 μm以上且500 μm以下,其中,更佳為15 μm以上或者400 μm以下,其中,尤其進而較佳為20 μm以上或者350 μm以下。 <導電構件用黏著片材之用途> 本黏著片材於例如個人電腦、行動設備終端(PDA)、遊戲機、電視(TV)、汽車導航系統、觸控面板、手寫板等圖像顯示裝置、例如電漿顯示器(PDP)、液晶顯示器(LCD)、有機EL顯示器(OLED)、無機EL顯示器、電泳顯示器(EPD)、干擾調變顯示器(IMOD)等使用圖像顯示面板之圖像顯示裝置中,適合貼合各構成構件、其中導電構件、其中具有透明導電層及/或由包含銅之金屬材料形成之導體圖案之導電構件。又,亦適合貼合包含含有ITO或者IGZO之透明導電層及/或具有由包含銅或銀之金屬材料形成之導體圖案之透明導電層之導電構件。 <導電構件積層體> 本發明之導電構件積層體(以下,亦省略後稱為「本積層體」)可藉由將本黏著片材與導電構件、例如透明導電層之導電層面貼合而獲得。 本積層體只要具有至少將本黏著片材之任一黏著劑層面與透明導電層之導電層面貼合而成之構成即可。 於本黏著片材為兩面黏著片材之情形時,本積層體亦可具有將本黏著片材之兩黏著劑層面與透明導電層之導電層面貼合而成之構成。 上述透明導電層亦可以覆蓋其導電膜之導電層面之方式形成利用烯烴系聚合物、胺基甲酸酯系聚合物、環氧系聚合物、丙烯酸系聚合物、聚矽氧系聚合物、或者無機玻璃等而形成之絕緣保護膜(鈍化膜)。 於此情形時,本黏著片材並未與透明導電層面直接貼合(並未與透明導電層面直接相接)。本黏著片材即便源自本組合物之成分(尤其是酸成分)浸透而自該絕緣膜到達至透明導電層,亦可藉由1,2,3-***之作用防止透明導電層腐蝕。尤其是由於1,2,3-***之水溶性較高,於本黏著片材於濕熱環境下吸濕時容易移動至透明導電層,故而可實現優異之金屬腐蝕防止效果。 如此,根據本黏著片材,不論有無絕緣保護膜,不僅可實現被黏著體之金屬離子所導致之黏著劑層之變色或變質防止效果,亦可實現針對被黏著體之優異之金屬腐蝕防止效果。 與導電層面貼合所得之本積層體可較佳地用於觸控面板。作為觸控面板,可列舉電阻膜方式、靜電電容方式、電磁感應方式等方式者,較佳為靜電電容方式。 作為上述透明導電層,只要為至少於單面之表層具有導電層者即可,可列舉藉由蒸鍍或濺鍍、塗佈等於透明基材之表層設置有導電物質而成之透明導電層。 透明導電層之導電層所使用之導電物質並無特別限定,具體而言,除氧化銦、銦-鎵-鋅複合氧化物、摻錫之氧化銦(ITO)、氧化鋅、氧化鎵、氧化鈦等金屬氧化物以外,亦可列舉銀、銅、鉬、鋁等金屬材料。其中,可較佳地使用透明性優異之摻錫之氧化銦(ITO)及銦-鎵-鋅複合氧化物(IGZO)。又,就導電性優異之觀點而言,亦可較佳地使用銅或銀。於透明導電層中,作為欲利用導電物質形成圖案之基材,並無特別限定,可列舉玻璃、樹脂膜等。 典型而言,透明導電層至少於單面之表層具有導電層。又,典型而言,於透明導電層以引繞周邊部之方式形成有將銅或銀作為主成分之導體圖案(配線圖案)。1,2,3-***對其中之銅之耐腐蝕可靠性較高,因此包含其之本黏著片材可尤其較佳地用於具備由包含銅之金屬材料形成之導體圖案之導電構件。 作為其他本積層體之具體例,例如可列舉:脫模膜/本黏著片材/觸控面板、脫模膜/本黏著片材/保護面板、脫模膜/本黏著片材/圖像顯示面板、圖像顯示面板/本黏著片材/觸控面板、圖像顯示面板/本黏著片材/保護面板、圖像顯示面板/本黏著片材/觸控面板/本黏著片材/保護面板、偏光膜/本黏著片材/觸控面板、偏光膜/本黏著片材/觸控面板/本黏著片材/保護面板等構成。又,於上述構成中,可列舉於本黏著片材與和其相鄰之觸控面板、保護面板、圖像顯示面板、偏光膜等構件之間介置有上述導電層之所有構成。但是,並不限定於該等積層例。 再者,上述觸控面板亦包含使觸控面板功能內置於保護面板而成之結構體或使觸控面板功能內置於圖像顯示面板而成之結構體。 <圖像顯示裝置> 本發明之圖像顯示裝置(以下,亦省略後稱為「本裝置」)至少具有本積層體、圖像顯示面板及表面保護面板作為構成構件。 更具體而言,可列舉將本黏著片材與透明導電層之導電層面貼合而得之本積層體***至圖像顯示面板與表面保護面板之間之構成之圖像顯示裝置。此時,於圖像顯示面板側亦使用本黏著片材。 作為表面保護面板之材質,除玻璃以外,亦可為丙烯酸系樹脂、聚碳酸酯系樹脂、環烯烴聚合物等脂環式聚烯烴系樹脂、苯乙烯系樹脂、聚氯乙烯系樹脂、酚系樹脂、三聚氰胺系樹脂、環氧系樹脂等塑膠。 圖像顯示面板係由除偏光膜以外之相位差膜等其他光學膜、液晶材料及背光光源系統構成(通常,本組合物或黏著物品對圖像顯示面板之被接著面成為光學膜),根據液晶材料之控制方式而存在STN(Super Twisted Nematic,超扭轉向列)方式或VA(Vertical Aligned,垂直配向)方式或IPS(In-Plane Switching,橫向電場效應)方式等,可為任何方式。 作為本圖像顯示裝置,例如可構成液晶顯示器、有機EL顯示器、無機EL顯示器、電子紙、電漿顯示器及微機電系統(MEMS)顯示器等圖像顯示裝置。 <語句之說明> 於本說明書中,於表述為「X~Y」(X、Y為任意之數字)之情形時,只要未特別說明,則包含「X以上且Y以下」之意義,並且包含「較佳為大於X」或者「較佳為小於Y」之意義。 又,於表述為「X以上」(X為任意之數字)或者「Y以下」(Y為任意之數字)之情形時,包含「較佳為大於X」或者「較佳為未達Y」之意圖。 一般而言,所謂「片材」,於JIS中之定義中,係指較薄、其厚度小於長度與寬度之商且平坦之製品,一般而言,所謂「膜」,係與長度及寬度相比厚度極小且最大厚度被任意地限定之較薄且平坦之製品,通常係指以輥之形供給者(日本工業標準JIS K6900)。然而,片材與膜之交界並不確定,於本發明中,無需於語言上對兩者進行區別,因此,於本發明中,於稱為「膜」之情形時亦包含「片材」,於稱為「片材」之情形時亦包含「膜」。 [實施例] 以下,藉由實施例及比較例進而詳細地進行說明。但是,本發明並不限定於該等實施例。 <(甲基)丙烯酸系(共)聚合物> (甲基)丙烯酸系(共)聚合物使用以下者。

g代替1,2,3-***作為金屬腐蝕防止劑,除此以外,以與實施例1-1相同之方式製作黏著片材積層體。針對該黏著片材積層體,進行下述各種評價。結果示於表1。 [比較例1-3] 使用甲苯并***(4-甲基苯并***與5-甲基苯并***之混合物)(Shipro Kasei公司製造,商品名「SEETEC TT-R」)5 g代替1,2,3-***作為金屬腐蝕防止劑,除此以外,以與實施例1-1相同之方式製作黏著片材積層體。針對該黏著片材積層體,進行下述各種評價。結果示於表1。 [比較例1-4] 使用2,5-二巰基-1,3,4-噻二唑(TOYOBO公司製造,商品名「MTD」)5

Å之銅膜依序積層而成之金屬膜之往返線,並且於該往返線之兩末端形成2 mm見方之正方形而形成銅圖案(長度約97 cm),製作耐腐蝕可靠性評價用銅玻璃基板(參照圖1(A))。 將上述實施例及比較例中製作之黏著片材積層體(黏著片材厚度150 μm)之單面之剝離膜剝離,並利用手壓輥將聚對苯二甲酸乙二酯(PET)膜(東洋紡織公司製造,商品名「COSMOSHINE A4100」,125 μm)貼附於其露出面。繼而,將上述附PET膜之黏著片材切成52 mm×45 mm後,將剩下之剝離膜剝離,如圖1(B)所示,以將金屬膜之往返線上被覆之方式利用手壓輥將該黏著片材貼附於耐腐蝕可靠性評價用銅玻璃基板,進而,隔著PET膜,以實施例1-1及比較例1-1~1-4之波長365 nm之累計光量成為3000 mJ/cm2 、實施例1-2及1-3之波長365 nm之累計光量成為2000 mJ/cm2 之方式利用高壓水銀燈照射紫外線,使之進行紫外線交聯,製作耐腐蝕可靠性評價用樣品(附黏著片材之銅配線)(參照圖1(D))。 預先測定該耐腐蝕可靠性評價用樣品(附黏著片材之銅配線)中之銅配線之室溫下之電阻值(Ω0)。 另一方面,將該耐腐蝕可靠性評價用樣品(附黏著片材之銅配線)於65℃・90%RH環境下保管500小時,保管後測定耐腐蝕可靠性評價用樣品(附黏著片材之銅配線)中之銅配線之電阻值(Ω)。 並且,算出銅電阻值、即線末端間電阻值之變化率(%)[((Ω/Ω0)-1)×100],於表1中表示成「電阻值變化」。 關於耐腐蝕可靠性,將電阻值之變化率為20%以上者判定為「×(poor)」,將未達20%者判定為「○(good)」。結果示於表1。 (2)耐發泡可靠性 將實施例及比較例中製作之黏著片材積層體(厚度150 μm)之單面之剝離膜剝離,並利用手動輥貼合於鈉鈣玻璃板(150×200 mm,厚度0.55 mm)。進而,將剩餘之剝離膜剝離,一面使化學強化玻璃板(180×220 mm,厚度0.6 mm)對齊,一面利用手動輥貼合。 繼而,將貼合品於60℃、0.2 MPa環境下進行20分鐘高壓釜處理。使用金屬鹵化物燈照射裝置(牛尾電機公司製造,型號UVC-0516S1,LAMP UVL-8001M3-N),以每照射1次而波長365 nm下之照射量成為3000 mJ/cm2 之方式調整輸送帶速度、放射照度,針對該樣品照射15次後,觀察外觀之變化。 關於耐發泡可靠性,於對外觀進行觀察時,將與紫外線照射前不存在變化者判定為「○(good)」,將產生氣泡者判定為「×(poor)」。結果示於表1。 (3)紫外線硬化特性 (紫外線硬化前儲存彈性模數G') 紫外線硬化前之儲存彈性模數係藉由如下而求出:將將使實施例及比較例中製作之黏著片材以成為1~2 mm厚度之方式積層而成者沖裁成直徑20 mm之圓狀而成者作為測定試樣,並使用流變儀(英弘精機股份有限公司製造之「MARS」),以黏著治具:Φ25 mm平行板、應變:0.5%、頻率:1 Hz、溫度:-50~200℃、升溫速度:3℃/min測定-50℃~200℃下之動態儲存彈性模數G',並讀取125℃下之儲存彈性模數值。結果示於表1。 (紫外線硬化後儲存彈性模數G') 紫外線硬化後之儲存彈性模數係以如下方式進行測定。 利用高壓水銀燈隔著PET膜對實施例及比較例中製作之黏著片材照射紫外線而使之進行紫外線交聯。此時,關於實施例1-1及比較例1-1~1-4,以波長365 nm之累計光量成為3000 mJ/cm2 之方式進行照射,實施例1-2及1-3係以該積層光量成為2000 mJ/cm2 之方式進行照射。將使以如上方式進行紫外線交聯後之黏著片材以成為厚度1~2 mm之方式積層並沖裁成直徑20 mm之圓狀而成者作為測定試樣。 使用流變儀(英弘精機股份有限公司製造,商品名「MARS」)以黏著治具:Φ25 mm平行板、應變:0.5%、頻率:1 Hz、溫度:-50~200℃、升溫速度:3℃/min測定-50℃~200℃下之該測定試樣之動態儲存彈性模數G',並讀取125℃下之儲存彈性模數值,藉此求出紫外線硬化後之儲存彈性模數。結果示於表1。 關於紫外線硬化特性,對紫外線硬化前儲存彈性模數G'與紫外線硬化後儲存彈性模數G'進行比較,將硬化後之值明顯上升者判定為「○(good)」,將值幾乎未變化者判定為「×(poor)」。結果示於表1。 [表1] (評價結果) 實施例1-1~1-3之黏著片材含有1,2,3-***作為金屬腐蝕防止劑,藉此,銅配線之電阻值之變化較少,且耐腐蝕可靠性優異。又,耐發泡可靠性、紫外線硬化特性亦良好。 另一方面,比較例1-1不包含金屬腐蝕防止劑,而耐腐蝕可靠性較差。 比較例1-2雖包含苯并***作為金屬腐蝕防止劑,但因苯并***之特性而耐發泡可靠性較差。 比較例1-3雖包含甲苯并***作為金屬腐蝕防止劑,但因甲苯并***之特性而耐發泡可靠性較差。 比較例1-4雖包含二巰基噻二唑作為金屬腐蝕防止劑,但由於二巰基噻二唑會吸收紫外線,故而黏著片材之紫外線硬化特性較差。 根據以上之結果可知,1,2,3-***由於熔點約為20℃,且於常溫下幾乎為液體,故而於黏著片材之實際製造步驟中,容易添加至黏著主劑中,又,向黏著主劑之分散性亦優異。 又,亦明確1,2,3-***由於水溶性較高,於黏著片材於濕熱環境下吸濕時,容易移動至金屬層(銅配線)之表面,故而可發揮優異之金屬腐蝕防止效果。 又,亦明確1,2,3-***由於在波長300~400 nm之分光光度下不存在吸收,故而不會阻礙UV(Ultraviolet,紫外線)硬化特性。 如上所述,發現1,2,3-***與先前之金屬腐蝕防止劑相比具有優異之特性,尤其有效地用於導電構件用之黏著片材。 <實施例2> [實施例2-1] 向(甲基)丙烯酸系(共)聚合物(A-1)1 kg中添加丙氧化季戊四醇聚丙烯酸酯(新中村化學工業公司製造,商品名「ATM-4PL」)200

(Metal corrosion inhibitor) The composition contains 1,2,3-triazole. 1,2,3-triazole has a function as a metal corrosion preventing agent for a conductive layer of a conductive member. 1,2,3-triazole is preferably used as a composition containing 1,2,3-triazole because of its copper corrosion resistance to copper and excellent foaming reliability as an adhesive sheet. A conductive member having a transparent conductive layer and a conductor pattern (wiring pattern) formed of a metal material containing copper. The reason for this is that corrosion is prevented by forming a protective film in which copper atoms are chemically bonded to molecules of 1,2,3-triazole by a surface of a conductor pattern formed of a metal material containing copper. Further, in the conductive member having the conductor pattern formed of the metal material containing silver, the effect of the protective film obtained by using 1,2,3-triazole can be similarly achieved. Further, 1,2,4-triazole is present as an isomer of 1,2,3-triazole. The 1,2,4-triazole is a solid having a melting point of about 120 ° C. On the other hand, the melting point of 1,2,3-triazole is about 20 ° C, and it is substantially in a liquid state at room temperature. Therefore, the 1,2,3-triazole has an advantage that it is excellent in dispersibility when mixed in an adhesive composition, can be uniformly mixed, and is excellent in master batching. In the present invention, it is preferably 0.01 parts by mass or more and 5 parts by mass based on 100 parts by mass of the (meth)acrylic (co)polymer, from the viewpoint of the leaching of the metal corrosion preventing agent or the metal corrosion preventing effect. The ratio of the parts by mass or less is 1,2,3-triazole, and it is further preferable to contain 1,2,3-triazole in a ratio of 0.1 part by mass or more or 1 part by mass or less, and further preferably The ratio of 0.2 parts by mass or more or 0.5 parts by mass or less contains 1,2,3-triazole. Further, 1,2,3-triazole may be used in combination with 1,2,4-triazole in the present composition. (Phosphite compound) The composition may further contain a phosphite compound. The phosphite compound is not only not corrosive in itself, but also stabilizes an acid component such as a carboxyl group. Therefore, by formulating the phosphite compound in the present composition containing a specific (meth)acrylic (co)polymer, even if the composition contains an acid component, oxidative degradation of the conductive member as the adherend can be prevented. When the composition does not contain an acid component, it is of course possible to prevent oxidative degradation of the conductive member as the adherend. Therefore, if an adhesive sheet is formed from the present composition containing a phosphite compound, it may have a conductive member (typically, a transparent conductive layer containing ITO and/or a conductor formed of a metal material containing copper or silver) The conductive member of the pattern has corrosion resistance reliability and can prevent oxidative degradation of the conductive member. Therefore, for example, it can be preferably used as an adhesive sheet for an image display device having a touch panel. The phosphite compound which the composition may contain is not limited. Particularly preferred is a phosphite compound represented by the following formula (1). Formula (1) P[-OR] 3 (wherein R is a hydrocarbon, specifically, a substituted or unsubstituted aromatic, an aliphatic ring, an alkyl group, etc.; and a plurality of R may be the same or different Further, a plurality of adjacent R groups may be bonded to each other to form a saturated or unsaturated ring structure. Further, it may be a compound containing two or more structural units represented by the above formula (1). The various phosphite compounds represented by the above formula (1) are blended in the present composition containing a specific (meth)acrylic (co)polymer and 1,2,3-triazole, and as a result, any sub-Asian compound is confirmed.

Into the structure. By adopting such a structure, a double bond crosslinkable functional group such as a (meth) acrylonitrile group or a vinyl group can be chemically bonded to a (meth)acrylic (co)polymer. Further, by binding the crosslinking agent to the (meth)acrylic (co)polymer, there is a tendency to suppress the bleeding of the crosslinking agent or the unexpected plasticization of the present adhesive sheet. Further, since the crosslinking agent is bonded to the (meth)acrylic (co)polymer to promote the reaction efficiency of the photocrosslinking reaction, a cured product having a higher cohesive strength tends to be obtained. The composition may further comprise a monofunctional monomer which is reactive with the crosslinkable functional groups of the crosslinking agent.

(Photopolymerization initiator) In the case of crosslinking by light irradiation, it is preferred to contain a photopolymerization initiator. The radical generating mechanism based on the photopolymerization initiator is classified into two types, an α-cleavage type which cleaves and decomposes one's own single bond to generate a radical, and generates a radical by exciting hydrogen from a compound in the system. Dehydrogenation type. Among these, a dehydrogenation type photocrosslinking initiator is preferably used. In the case where an organic crosslinking agent having a (meth)acryl fluorenyl group is used as the crosslinking agent, it is particularly preferred to further add a photopolymerization initiator. The reason is that the radicals are generated by light irradiation to become the starting point of the polymerization reaction in the system. The photopolymerization initiator can be suitably used by those currently known. Among them, from the viewpoint of easiness of control of the crosslinking reaction, a photopolymerization initiator which induces ultraviolet rays having a wavelength of 380 nm or less is preferred. On the other hand, in terms of obtaining a higher photoreactivity and inducing light to easily reach the deep portion of the adhesive sheet, it is preferred to initiate photopolymerization of light having a wavelength longer than 380 nm. Agent. The photopolymerization initiator is classified into two broad categories according to a radical generating mechanism, and is roughly classified into a cleavage type photopolymerization initiator which can cleave and decompose a single bond of a photopolymerization initiator itself to generate a radical, and is activated by light. The starter and the hydrogen donor in the system form a dehydrogenation type photopolymerization initiator which excites the complex and transfers the hydrogen to the hydrogen of the body. The cleavage type photopolymerization initiator in these forms decomposes into a compound upon generation of a radical by light irradiation, and once excited, loses the function as a crosslinking initiator. Therefore, it does not remain in the form of an active species in the adhesive material after the completion of the crosslinking reaction, and it is not preferable to cause an unexpected light deterioration or the like of the adhesive material. On the other hand, when the dehydrogenation type photopolymerization initiator is subjected to a reaction for generating a radical by irradiation with an active energy ray such as ultraviolet rays, a decomposition product such as a cleavage type photopolymerization initiator does not occur, so that it is difficult to become a reaction after completion of the reaction. The volatile component is useful in reducing the damage to the adherend. The cleavage type photopolymerization initiator is preferably bis(2,4,6-trimethylbenzylidene) in terms of high sensitivity to light and decomposition to decomposed after the reaction. -phenylphosphine oxide, 2,4,6-trimethylbenzimidyldiphenylphosphine oxide, (2,4,6-trimethylbenzylidene)ethoxyphenylphosphine oxide, double ( A fluorenylphosphine-based photopolymerization initiator such as 2,6-dimethoxybenzylidene) 2,4,4-trimethylpentylphosphine oxide.

In addition, any one of the above-mentioned photopolymerization initiators or a derivative thereof may be used, or two or more of them may be used in combination.

Further, the photopolymerization initiator or the sensitizer may be contained in a state of being bonded to a (meth)acrylic (co)polymer.

The metal halide lamp irradiation device (manufactured by Oxtail Electric Co., Ltd., model UVC-0516S1, LAMP UVL-8001M3-N) was used to adjust the conveyor belt in such a manner that the irradiation amount at a wavelength of 365 nm became 3000 mJ/cm 2 per irradiation. The speed and irradiance were observed after 15 times of irradiation on the sample. Regarding the foaming reliability, when the appearance is observed, it is judged as "○ (good)" in the case where there is no change before the ultraviolet irradiation, and "× (poor)" is determined in the bubble generation. The results are shown in Table 1. (3) Ultraviolet curing property (Storage elastic modulus G' before ultraviolet curing) The storage elastic modulus before ultraviolet curing is obtained by: making the adhesive sheet produced in the examples and the comparative examples into 1 In the case of a thickness of ~2 mm, a laminate of 20 mm in diameter was used as a measurement sample, and a rheometer ("MARS" manufactured by Hidehiro Seiki Co., Ltd.) was used to adhere the jig: Φ25 mm parallel plate, strain: 0.5%, frequency: 1 Hz, temperature: -50 to 200 ° C, heating rate: 3 ° C / min, the dynamic storage elastic modulus G' at -50 ° C to 200 ° C is measured, and read Storage elastic modulus values at 125 °C. The results are shown in Table 1. (Storage elastic modulus G' after ultraviolet curing) The storage elastic modulus after ultraviolet curing was measured as follows. The adhesive sheets produced in the examples and the comparative examples were irradiated with ultraviolet rays by a high pressure mercury lamp through a PET film to be subjected to ultraviolet crosslinking. At this time, in Example 1-1 and Comparative Examples 1-1 to 1-4, the integrated light amount at a wavelength of 365 nm was irradiated at 3000 mJ/cm 2 , and Examples 1-2 and 1-3 were used. Irradiation was carried out so that the amount of laminated light became 2000 mJ/cm 2 . The adhesive sheet which was subjected to the ultraviolet crosslinking as described above was laminated to a thickness of 1 to 2 mm and punched into a circular shape having a diameter of 20 mm as a measurement sample. Using a rheometer (manufactured by Yinghong Seiki Co., Ltd., trade name "MARS") to adhere the jig: Φ25 mm parallel plate, strain: 0.5%, frequency: 1 Hz, temperature: -50 to 200 ° C, heating rate: 3 The dynamic storage elastic modulus G' of the measurement sample at -50 ° C to 200 ° C was measured at ° C / min, and the stored elastic modulus value at 125 ° C was read, thereby determining the storage elastic modulus after ultraviolet curing. The results are shown in Table 1.

On the other hand, Comparative Example 1-1 did not contain a metal corrosion inhibitor, and corrosion resistance was poor. Although Comparative Example 1-2 contains benzotriazole as a metal corrosion preventing agent, the foaming reliability is inferior due to the characteristics of benzotriazole. In Comparative Example 1-3, toluene triazole was used as the metal corrosion preventing agent, but the foaming reliability was inferior due to the characteristics of tolyltriazole. Although Comparative Example 1-4 contains dimercaptothiadiazole as a metal corrosion preventing agent, since the dimercaptothiadiazole absorbs ultraviolet rays, the ultraviolet curing property of the adhesive sheet is inferior. According to the above results, since 1,2,3-triazole has a melting point of about 20 ° C and is almost liquid at normal temperature, it is easily added to the adhesive main component in the actual manufacturing step of the adhesive sheet, and The dispersibility to the adhesive main agent is also excellent. Further, it is also clear that 1,2,3-triazole is highly water-soluble, and when the adhesive sheet absorbs moisture in a hot and humid environment, it easily moves to the surface of the metal layer (copper wiring), thereby exhibiting excellent metal corrosion prevention. effect. Further, it is also clear that 1,2,3-triazole does not hinder UV (Ultraviolet) hardening characteristics because it does not absorb at a spectrophotometer of a wavelength of 300 to 400 nm. As described above, it has been found that 1,2,3-triazole has excellent characteristics as compared with the prior metal corrosion inhibitor, and is particularly effective for an adhesive sheet for a conductive member. <Example 2> [Example 2-1] To a 1 kg of a (meth)acrylic (co)polymer (A-1), a pentaerythritol polyacrylate (manufactured by Shin-Nakamura Chemical Co., Ltd., trade name "ATM-4PL") 200 g as a crosslinking agent, and a mixture of 4-methylbenzophenone and 2,4,6-trimethylbenzophenone (manufactured by Lamberti Co., Ltd., trade name "Esacure TZT") 10 g was used as a photopolymerization initiator and uniformly mixed to obtain a resin composition for an intermediate layer.
