2.黏著性層疊體 2. Adhesive laminate

本發明中，所謂黏著性層疊體是包含基材及黏著劑層 的層疊體，意味著黏著片之剝離片以外的部份。 In the present invention, the so-called adhesive laminate includes a substrate and an adhesive layer The laminated body means the part other than the release sheet of the adhesive sheet.

以下，針對黏著性層疊體的構成元件的基材及黏著劑層說明。 Hereinafter, the base material and the adhesive layer of the components of the adhesive laminate will be described.

(1)基材 (1) Substrate

本發明的基材，尤其不加以限制，以往，可從作為黏著片的基材所使用的塑膠薄膜、紙基材、不織布等之中適當選擇來使用。 The substrate of the present invention is not particularly limited, and conventionally, it can be suitably selected from plastic films, paper substrates, non-woven fabrics, etc. used as the substrate of the adhesive sheet.

例如，只要是塑膠薄膜，即可舉例如聚對苯二甲酸乙二醇酯、聚對苯二甲酸丁二醇酯、聚萘二酸乙二醇酯等的聚酯薄膜、聚乙烯薄膜、聚丙烯薄膜、聚氯乙烯薄膜、聚偏氯乙烯薄膜、聚乙烯醇薄膜、乙烯-乙酸乙烯酯共聚物薄膜、聚苯乙烯薄膜、聚碳酸酯薄膜、聚甲基戊烯薄膜、聚碸薄膜、聚醚醚酮薄膜、聚醚碸薄膜、聚苯硫醚薄膜、聚醚亞胺薄膜、聚醯亞胺薄膜、含氟樹脂薄膜、聚醯胺薄膜、丙烯酸樹脂薄膜、降冰片烯系樹脂薄膜、環烯羥樹脂薄膜等。 For example, as long as it is a plastic film, for example, polyester film such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyethylene film, and poly Propylene film, polyvinyl chloride film, polyvinylidene chloride film, polyvinyl alcohol film, ethylene-vinyl acetate copolymer film, polystyrene film, polycarbonate film, polymethylpentene film, polyvinyl chloride film, polyvinyl Ether ether ketone film, polyether sulfide film, polyphenylene sulfide film, polyetherimide film, polyimide film, fluorine-containing resin film, polyamide film, acrylic resin film, norbornene resin film, ring Alkenyl resin film, etc.

並且，基材的膜厚通常是設10~300μm的範圍內的值為佳，以設20~150μm的範圍內的值更佳。 In addition, the film thickness of the substrate is usually preferably set to a value in the range of 10 to 300 μm, and more preferably set to a value in the range of 20 to 150 μm.

(2)黏著劑層 (2) Adhesive layer

本發明的黏著劑層，尤其不加以限制，可使用習知的丙烯系、矽系、尿烷系、橡膠系等的黏著劑。 The adhesive layer of the present invention is not particularly limited, and conventional acrylic, silicon, urethane, rubber, etc. adhesives can be used.

又，黏著性的型式也可以使用活化能射線硬化型或熱 熔型的黏著劑。 In addition, the adhesive type can also use active energy ray hardening type or heat Melting adhesive.

並且，相關黏著劑層的膜厚，通常是以1~200μm的範圍內的值為佳，並以5~50μm的範圍內的值更佳。 In addition, the film thickness of the relevant adhesive layer is usually preferably in the range of 1 to 200 μm, and more preferably in the range of 5 to 50 μm.

(3)其他的層 (3) Other layers

並且，也可以在黏著性層疊體加上基材及黏著劑層，層疊中間層或易接著層等的其他的層。 In addition, a base material and an adhesive layer may be added to the adhesive laminate, and other layers such as an intermediate layer or an easily bonding layer may be laminated.

(4)黏附體貼附用部份 (4) Adhesive part for attachment

本發明的黏著性層疊體，其特徵為：具有貼附於黏附體用的黏附體貼附用部份。 The adhesive laminate of the present invention is characterized by having an adhesive body attaching part for attaching to an adhesive body.

本發明的黏附體貼附用部份的樣態，尤其不加以限制，但是在以下記載中，實際上有特性不同的黏著性層疊體的複數黏著片混同的場合，即使測量黏著力等的特性進行辨識，會有使用黏附體貼附用部份的特性測量尤其變得困難的樣態，即在辨識黏著片時，例示如後述之辨識用部份尤其變得有需要的樣態進行說明。 The aspect of the part for sticking of the adhesive body of the present invention is not particularly limited. However, in the following description, if there are actually multiple adhesive sheets of an adhesive laminate with different characteristics, even if the characteristics such as adhesive force are measured For identification, it is particularly difficult to measure the characteristics of the sticking part using the adhesive. That is, when the sticky sheet is recognized, it will be explained by exemplifying the situation where the identification part described later becomes particularly necessary.

(4)-1面積 (4)-1 area

首先，使用黏附體貼附用部份的特性測量尤其變得困難的第1樣態是如第1(a)圖表示，例舉黏附體貼附用部份12的形狀的面積為400mm2以下的值的樣態。 First of all, the first aspect that makes it particularly difficult to measure the characteristics of the part for sticking using the adhesive is as shown in Figure 1(a). For example, the area of the part 12 for sticking to the sticky body is 400 mm 2 or less. The way.

此一理由為當黏附體貼附用部份的平面形狀的面積成為400mm2以下的值時，面積變得不足，即使以黏附體貼 附用部份作為直接試樣的場合，或加工製成試樣的場合，使用黏附體貼附用部份的特性測量會變得困難。 The reason for this is that when the area of the planar shape of the part for application of the adherend becomes less than 400 mm 2 , the area becomes insufficient, even if the part for application of the adherend is used as a direct sample or processed into a sample In the case of using the adhesive body to measure the characteristics of the attached part will become difficult.

又，黏附體貼附用部份的平面形狀在第1(a)圖是形成圓形，但尤其不加以限制，也可配合用途，例如橢圓形或長方形的任意形狀。 In addition, the planar shape of the part for attaching the adhesive body is circular in Fig. 1(a), but it is not particularly limited, and it can be any shape such as an ellipse or a rectangle.

再者，本發明中的「平面形狀」是如第1(a)圖表示，意味著從基材側的上方眺望黏著片時的形狀。 In addition, the "planar shape" in the present invention is as shown in Fig. 1(a), and means the shape when the adhesive sheet is viewed from above the substrate side.

(4)-2非接觸部 (4)-2 non-contact part

又，作為使用黏附體貼附用部份的特性測量尤其變得困難的第2樣態是如第2(a)~(c)圖表示，黏附體貼附用部份12的黏著劑層4可舉例有一部份不與黏附體100接觸的非接觸部50的樣態。 In addition, as the second aspect that makes it particularly difficult to measure the characteristics of the part for attaching using an adhesive, as shown in Figures 2(a) to (c), the adhesive layer 4 of the part 12 for attaching the adhesive can be exemplified There is a non-contact portion 50 that does not contact the adherend 100.

其理由為黏附體貼附用部份具有非接觸部的場合，測量結果會被非接觸部的特性所影響，使得使用黏附體貼附用部份的特性測量會變得困難。 The reason is that when the part for attaching the adhesive body has a non-contact part, the measurement result will be affected by the characteristics of the non-contact part, making it difficult to measure the characteristics of the part for attaching using the adhesive body.

並且，具有如上述非接觸部的黏附體貼附用部份是例如使用於組裝如數位相機的透鏡單元的精密零組件時，貼附保護薄膜以使得黏著劑層不與透鏡部份直接接觸的場合等。 In addition, the part for attaching the adhesive body with the non-contact part as described above is used for assembling precision components such as the lens unit of a digital camera, when a protective film is attached so that the adhesive layer does not directly contact the lens part. Wait.

因此，對於非接觸部的平面形狀、立體形狀、配置及個數等，尤其不加以限制，但大致的例是可舉例如第2(a)~(c)圖表示的樣態。 Therefore, the planar shape, the three-dimensional shape, the arrangement, and the number of the non-contact parts are not particularly limited, but a rough example is the aspect shown in Figs. 2(a) to (c).

又，非接觸部是例如進行黏附體貼附用部份衝切加工 的同時，可以上側模框的凹部及下側模框的凸部進行壓力加工形成。 In addition, the non-contact part is for example a partial punching process for attaching the adhesive body At the same time, the concave part of the upper mold frame and the convex part of the lower mold frame can be formed by pressing.

再者，第2(a)圖為本發明的黏著片的上視圖，以第2(b)圖是以通過第2(a)圖的線B-B的平面裁斷黏著片時的剖視圖，第2(c)圖是表示將第2(b)圖表示之黏著片的黏附體貼附用部份貼附於黏附體的狀態的圖。 Furthermore, Figure 2(a) is a top view of the adhesive sheet of the present invention, Figure 2(b) is a cross-sectional view when the adhesive sheet is cut through a plane passing through the line BB of Figure 2(a), and Figure 2(b) c) Figure is a diagram showing a state where the part for attaching the adhesive body of the adhesive sheet shown in Figure 2(b) is attached to the adhesive body.

(5)辨識用部份 (5) Identification part

本發明的黏著性層疊體，其特徵為：具有辨識黏著性層疊體的特性用的辨識用部份。 The adhesive laminate of the present invention is characterized by having an identification part for identifying the characteristics of the adhesive laminate.

其理由為黏附體貼附用部份的平面形狀雖然相同或類似，但如有黏著力等的特性不同的場合，仍可明確辨識從黏附體貼附用部份的平面形狀上辨識困難的複數種的黏著片。 The reason is that although the planar shape of the adhesive part is the same or similar, if there are different characteristics such as adhesive force, it can still be clearly distinguished from the planar shape of the adhesive part. Adhesive sheet.

以下，針對辨識用部份具體說明。 The following is a specific explanation for the identification part.

(5)-1辨識對象特性 (5)-1 Identify the characteristics of the object

作為辨識用部份所辨識對象的特性尤其不加以限制，但可舉例如黏著層的膠凝部份、儲存彈性率或基材或黏著性層疊體整體的黏著力、保持力、全光線穿透率、霧度值等。 The characteristics of the identified object as the identification part are not particularly limited, but for example, the gel part of the adhesive layer, the storage elastic modulus or the adhesive force of the substrate or the adhesive laminate as a whole, retention force, and total light penetration Rate, haze value, etc.

(5)-2形狀 (5)-2 shape

以從長方形、第1(a)圖、如第2(a)圖表示的大 致長方形、橢圓形、大致橢圓形、圓形、大致圓形、三角形、大致三角形、五角形、大致五角形、星形、英文字母及數字所成的群中選擇至少一種作為辨識用部份的平面形狀為佳。 From the rectangle, Figure 1(a), as shown in Figure 2(a) At least one of the group consisting of rectangle, ellipse, roughly ellipse, circle, roughly circle, triangle, roughly triangle, pentagon, roughly pentagon, star, English letters, and numbers is selected as the plane shape of the identification part Better.

其理由是設辨識用部份的平面形狀為該等形狀時，使用辨識用部份，可更為明確進行辨識。 The reason is that when the plane shape of the identification part is such a shape, the identification part can be used for more clear identification.

並藉著將辨識用部份的平面形狀設成該等形狀，即使從黏附體貼附用部份測量黏著性層疊體之黏著力等的特性困難的場合，仍可使用辨識用部份，更為容易且正確進行特性的測量。 And by setting the plane shape of the identification part to these shapes, even if it is difficult to measure the adhesive force of the adhesive laminate from the adhesive body attaching part, the identification part can still be used. It is easy and accurate to measure characteristics.

並且，以設辨識用部份的平面形狀如第3(a)表示的數字或第3(b)圖表示的英文字母的文字資訊為佳。 In addition, it is better to set the planar shape of the recognition part as the number shown in Figure 3(a) or the text information of the English alphabet shown in Figure 3(b).

其理由是只要如上述的文字資訊，即可更明確辨識黏著性層疊體的特性。 The reason is that the characteristics of the adhesive laminate can be more clearly recognized as long as the above-mentioned text information.

再者，第3(a)~(b)圖為本發明的黏著片的上視圖。 Furthermore, Figures 3(a)~(b) are top views of the adhesive sheet of the present invention.

(5)-3大小 (5)-3 size

並且，以設辨識用部份的平面形狀的最大直徑在20~300mm的範圍內的值為佳。 In addition, it is preferable to set the maximum diameter of the planar shape of the identification part within the range of 20 to 300 mm.

其理由為該最大直徑小於20mm的值時，目視辨識用部份的平面形狀變得困難，會有降低辨識性的場合。另一方面，該最大直徑大於300mm的值時，可平面配置在相 同剝離片上的黏附體貼附用部份的面積會有受到過度限制的場合。 The reason is that when the maximum diameter is less than 20 mm, it becomes difficult to visually recognize the planar shape of the part for identification, and the visibility may be reduced. On the other hand, when the maximum diameter is greater than 300mm, it can be arranged in a plane The area of the part for attaching the adhesive body on the release sheet may be excessively restricted.

再者，本發明的最大徑是意味著描繪外切於辨識用部份的平面形狀的圓時之該外切圓的直徑。 Furthermore, the maximum diameter in the present invention means the diameter of the circumscribed circle when a circle circumscribed to the plane shape of the identification part is drawn.

又，在設辨識用部份的平面形狀為長方形、大致長方形、橢圓形或大致橢圓形的場合，並從容易且正確測量黏著性層疊體的特性的觀點進入，設其長軸方向的長度在20~300mm的範圍內的值為佳，以在30~250mm的範圍內的值更佳，並以在45~200mm的範圍內的值最佳。 Furthermore, when the planar shape of the identification part is rectangular, substantially rectangular, elliptical, or substantially elliptical, and from the viewpoint of easy and accurate measurement of the characteristics of the adhesive laminate, the length in the major axis direction is assumed to be The value in the range of 20 to 300 mm is preferable, the value in the range of 30 to 250 mm is more preferable, and the value in the range of 45 to 200 mm is the most preferable.

並且，設其短軸方向的長度(寬度)在1~30mm的範圍內的值為佳，以在1.5~28mm的範圍內的值更佳，並以在2~25mm的範圍內的值最佳。 In addition, the length (width) in the minor axis direction is preferably in the range of 1 to 30 mm, and the value in the range of 1.5 to 28 mm is more preferable, and the value in the range of 2 to 25 mm is the best. .

(5)-4配置 (5)-4 configuration

並且，本發明是如第1(a)圖、第2(a)圖、第3(a)~(b)圖表示，其特徵為：黏附體貼附用部份12與辨識用部份14是平面配置在相同的剝離片2之上。 In addition, the present invention is shown in Fig. 1(a), Fig. 2(a), Fig. 3(a)~(b), and is characterized in that the part 12 for sticking and the part 14 for identification are The plane is arranged on the same release sheet 2.

其理由為藉如以上的構成，將黏附體貼附用部份具有的特性，表示於平面配置在相同的剝離片上的辨識用部份，可確實防止產生與其他黏著片的混同。 The reason is that with the above-mentioned structure, the characteristics of the part for sticking of the adhesive body are expressed in the part for identification that is arranged on the same release sheet on a plane, which can surely prevent confusion with other adhesive sheets.

又，黏附體貼附用部份的平面配置的樣態，基本上是與不具有辨識用部份之以往的黏著片的場合相同，如第1(a)圖、第2(a)圖、第3(a)~(b)圖表示，以在不降低使用時的操作性的範圍內，平面配置使成 形面積成為最大為佳。 In addition, the plane arrangement of the part for sticking of the adhesive body is basically the same as in the case of the conventional adhesive sheet without the part for identification, as shown in Fig. 1(a), Fig. 2(a), and Fig. 3(a)~(b) shows that the plane layout is used in a range that does not reduce the operability during use The shape area is preferably the largest.

另一方面，辨識用部份的平面配置的樣態是例如第1(a)圖、第2(a)圖表示，以沿著黏著片的任意的一邊的位置，或如第3(a)~(b)圖表示圍繞兩邊的角部附近，平面配置在平面配置著黏附體貼附用部份的部份的外側為佳。 On the other hand, the planar configuration of the identification part is shown in Fig. 1(a) and Fig. 2(a), with a position along any side of the adhesive sheet, or as in Fig. 3(a) ~(b) The figure shows the vicinity of the corners around the two sides, and it is better to arrange the plane on the outside of the part where the adhesive body is placed on the plane.

其理由為，如上述藉平面配置，可抑制黏附體貼附用部份之平面配置受到阻礙，並且也可抑制使用黏附體貼附用部份時之操作性的降低。 The reason is that, as described above, the planar arrangement can suppress the hindrance of the planar arrangement of the adhesive body sticking part, and can also suppress the decrease in operability when using the adhesive body sticking part.

但是，只要是不阻礙黏附體貼附用部份的平面配置，且不損及其操作性的範圍內，也可以平面配置通過平面配置著黏附體貼附用部份的部份之中。 However, as long as it does not hinder the planar arrangement of the part for attaching the adhesive body and does not impair its operability, it can also be arranged in a plane through the planar arrangement in the part of the part for attaching the adhesive body.

〔第2實施形態〕 [Second Embodiment]

本發明的第2實施形態是作為第1實施形態的黏著片的製造方法，其特徵為：包含下述步驟(I)~(II)的黏著片的製造方法。 The second embodiment of the present invention is a method of manufacturing an adhesive sheet as the first embodiment, and is characterized by a method of manufacturing an adhesive sheet including the following steps (I) to (II).

(I)準備至少層疊基材、黏著劑層及剝離片所成之成形加工前的黏著片的步驟，及(II)將包含基材及黏著劑層所構成的黏著性層疊體，在剝離片上成形加工成貼附於黏附體用的黏附體貼附用部份與辨識黏著性層疊體的特性用的辨識用部份，並將黏附體貼附用部份與辨識用部份平面配置在相同的剝離片上以獲得黏著片的步驟， 以下，以和第1實施形態不同的點為中心，一邊參閱圖示並具體說明本發明的第2實施形態。 (I) A step of preparing an adhesive sheet before forming and processing formed by laminating at least a base material, an adhesive layer and a release sheet, and (II) Put an adhesive laminate composed of a base material and an adhesive layer on the release sheet Forming and processing into the part for sticking to the sticky body and the part for distinguishing the characteristics of the adhesive laminate, and the part for sticking to the sticky body and the part for distinguishing are placed in the same plane and peeled off On the film to obtain the adhesive film, Hereinafter, the second embodiment of the present invention will be specifically described with reference to the drawings, focusing on the differences from the first embodiment.

1.步驟(I)：黏著片的準備步驟 1. Step (I): Preparation steps of the adhesive sheet

步驟(I)為準備至少層疊基材、黏著劑層及剝離片所成之成形加工前的黏著片的步驟。 Step (I) is a step of preparing an adhesive sheet before forming processing formed by laminating at least a base material, an adhesive layer and a release sheet.

上述步驟是可藉以往習知的方法進行。 The above steps can be carried out by conventionally known methods.

更具體而言，舉例如使用丙烯酸系的非活化能射線硬化型的黏著劑組成物的場合說明時，以使黏著劑組成物相對於剝離片進行塗抹暨乾燥形成黏著劑層之後，將基材層疊於所獲得的黏著劑層為佳。 More specifically, for example, when an acrylic non-active energy ray-curable adhesive composition is used, the adhesive composition is applied to the release sheet and dried to form an adhesive layer, and then the substrate It is better to laminate on the obtained adhesive layer.

並且，成形加工前的黏著片是預先製造帶狀的連續體，必要時，在以後的成形加工後，可以各預定間隔裁斷成單張。 In addition, the adhesive sheet before the forming process is a strip-shaped continuous body manufactured in advance, and if necessary, after the subsequent forming process, it can be cut into individual sheets at predetermined intervals.

1.步驟(II)：成形加工步驟 1. Step (II): forming processing steps

又，步驟(II)是如第4(a)~(e)圖表示，將包含基材6及黏著劑層4所構成的黏著性層疊體10，在剝離片2之上成形加工成黏附體貼附用部份12與辨識用部份(未圖示)，並將黏附體貼附用部份12與辨識用部份(未圖示)平面配置在相同的剝離片2之上獲得黏著片20的步驟。 In addition, step (II) is as shown in Figures 4(a) to (e), forming the adhesive laminate 10 composed of the base material 6 and the adhesive layer 4 on the release sheet 2 into an adhesive sticker The attachment part 12 and the identification part (not shown), and the adhesive body attachment part 12 and the identification part (not shown) are planarly arranged on the same release sheet 2 to obtain the adhesive sheet 20 step.

上述成形加工是可藉以往習知的方法進行，例如第4(a)~(b)圖表示的衝切加工或雷射加工等所成形。 The above-mentioned forming process can be performed by a conventionally known method, such as punching process or laser process as shown in Fig. 4(a) to (b).

並且，第4(a)~(b)圖是表示衝切加工步驟的側方剖視圖。 In addition, 4(a) to (b) are side cross-sectional views showing a punching process.

又，作為成形加工，如第4(a)~(b)圖表示，以使用具有對應黏附體貼附用部份12的平面形狀的第1加工手段214，及對應辨識用部份(未圖示)的平面形狀的第2加工手段(未圖示)的衝切加工機200，進行衝切加工為佳。 In addition, as the forming process, as shown in Figs. 4(a)~(b), the first processing means 214 having a plane shape corresponding to the part 12 for attaching the adhesive body is used, and the corresponding part for identification (not shown) The punching machine 200 of the second processing means (not shown) having a planar shape of) preferably performs punching processing.

其理由為只要是使用如上述衝切加工機的衝切加工，即可將辨識用部份與黏附體貼附用部份同時進行成形加工。 The reason is that as long as the punching process is performed using the punching machine as described above, the identification part and the adhesive body attaching part can be simultaneously formed.

並且，第4(a)~(b)圖表示的衝切加工中，如第2(a)~(c)圖表示的黏附體貼附用部份12的黏著劑層4為製造具有一部份不與黏附體100接觸之非接觸部50的樣態的黏著片20。 In addition, in the punching process shown in Figures 4(a)~(b), the adhesive layer 4 of the adhesive body attaching part 12 shown in Figures 2(a)~(c) is made to have a part The adhesive sheet 20 is in the form of a non-contact part 50 that does not contact the adhesive body 100.

以下，針對第4(a)~(b)圖表示的衝切加工具體說明。 Hereinafter, the punching process shown in Fig. 4(a) to (b) will be described in detail.

亦即，如第4(a)圖表示，成形加工前的黏著片20’在衝切加工機200的上側模框210及下側模框220分開的狀態下，以一定的移送間距朝著移送方向E移送之後，如第4(b)圖表示，在其移送期間中為上側模框210及下側模框220所加壓而進行衝切加工。 That is, as shown in Fig. 4(a), the adhesive sheet 20' before forming is transferred at a certain transfer pitch with the upper mold frame 210 and the lower mold frame 220 of the punching machine 200 separated After the transfer in the direction E, as shown in FIG. 4(b), the upper mold frame 210 and the lower mold frame 220 are pressurized and punched during the transfer period.

更具體而言，如第4(c)~(e)圖表示，相對於包含基材6及黏著劑層4所構成的層疊體之黏著性層疊體10，藉上側模框210的第1加工手段214形成與黏 附體貼附用部份12的平面形狀對應的切口的同時，藉上側模框210的第2加工手段(未圖示)形成與辨識用部份14的平面形狀對應的切口。 More specifically, as shown in Figs. 4(c) to (e), with respect to the adhesive laminate 10 including the laminate composed of the base material 6 and the adhesive layer 4, the first processing of the upper mold frame 210 Means 214 Formation and Stickiness The second processing means (not shown) of the upper mold frame 210 is used to form a notch corresponding to the planar shape of the identification part 14 along with the notch corresponding to the planar shape of the part 12 for attachment.

再者，第4(c)圖是藉第4(a)~(b)圖表示的衝切加工步驟所獲得的黏著片的上視圖，第4(d)圖是以通過第4(c)圖的線X-X的平面裁斷黏著片時的剖視圖，第4(e)圖是以通過第4(c)圖的線Y-Y的平面裁斷黏著片時的剖視圖。 Furthermore, Fig. 4(c) is a top view of the adhesive sheet obtained by the punching processing steps shown in Figs. 4(a)~(b), and Fig. 4(d) is a top view of the adhesive sheet obtained through the step 4(c) A cross-sectional view when the adhesive sheet is cut on the plane of line XX in the figure, and Fig. 4(e) is a cross-sectional view when the adhesive sheet is cut on a plane passing through the line YY of Fig. 4(c).

又，與此同時，藉上側模框210的凹部212與下側模框220的凸部222，相對於和成形加工前的黏著片20’的黏附體貼附用部份12相當位置的一部份形成拱形狀，藉此在黏附體貼附用部份12形成非接觸部50。 At the same time, with the concave portion 212 of the upper mold frame 210 and the convex portion 222 of the lower mold frame 220, a portion corresponding to the portion 12 for attaching the adhesive body of the adhesive sheet 20' before the forming process By forming an arch shape, a non-contact portion 50 is formed in the adhesive body attaching part 12.

之後，上側模框210及下側模框220一旦分開時，黏著片20及加工前的黏著片20’的連續體僅以一定的移送間距量被朝著移送方向E移送，重複以上的步驟。 After that, once the upper mold frame 210 and the lower mold frame 220 are separated, the continuum of the adhesive sheet 20 and the pre-processed adhesive sheet 20' is transferred in the transfer direction E by a certain transfer pitch, and the above steps are repeated.

並且，將以上步驟重複所獲得的黏著片20的連續體裁斷成單張，可獲得第4(c)~(e)圖表示最終的黏著片20。 Moreover, the continuum of the adhesive sheet 20 obtained by repeating the above steps is cut into a single sheet, and the final adhesive sheet 20 shown in Figures 4(c) to (e) can be obtained.

再者，如第4(c)~(e)圖表示最終的黏著片20為剝離除去黏著性層疊體10的黏附體貼附用部份12及辨識用部份14以外的部份。 Furthermore, as shown in Figs. 4(c) to (e), the final adhesive sheet 20 is a part other than the adhesive body attaching part 12 and the identification part 14 from which the adhesive laminate 10 is peeled and removed.

藉以上的進行，在黏著片的使用時，可容易將黏附體貼附用部份或辨識用部份剝離。 Through the above process, when the adhesive sheet is used, it is easy to peel off the sticking part or the identification part.

上述剝離除去步驟可在衝切加工起至裁斷或捲繞步驟 為止的任意時間點執行，也可根據場合而省略執行。 The above peeling and removing step can be from the punching process to the cutting or winding step It is executed at any point in time so far, and execution may be omitted depending on the occasion.

另外，其中一例，雖已具體說明第4(a)~(b)圖表示的衝切加工步驟，但是黏附體貼附用部份及辨識用部份成形用的衝切加工、形成非接觸部用的凹凸加工及裁斷成單張的裁斷加工的順序尤其不加以限制。 In addition, in one example, although the punching steps shown in Figures 4(a) to (b) have been described in detail, the punching process for forming the part for attaching the adherend and the part for identification is used for forming non-contact parts. The order of the concave-convex processing and the cutting into a single sheet is not particularly limited.

因此，例如，也可在將成形加工前的黏著片裁斷成單張之後，藉凹凸加工形成非接觸部，最後進行衝切加工。 Therefore, for example, after the adhesive sheet before the forming process is cut into a single sheet, the non-contact portion may be formed by uneven processing, and finally punching processing may be performed.

或者，也可以將成形加工前的黏著片進行衝切加工之後，裁斷成單張，最後藉凹凸加工形成非接觸部。 Alternatively, after punching the adhesive sheet before the forming process, it is cut into a single sheet, and finally the non-contact part is formed by uneven processing.

或者，也可以將成形加工前的黏著片進行衝切加工之後，藉凹凸加工形成非接觸部的同時裁斷成單張。 Alternatively, after punching the pressure-sensitive adhesive sheet before forming processing, the non-contact portion may be formed by uneven processing and cut into a single sheet.

〔產業上的可利用性〕 〔Industrial availability〕

以上如詳述，根據本發明的黏著片，藉著將包含基材及黏著劑層所構成的黏著性層疊體，在剝離片上，加工形成為貼附於黏附體用的黏附體貼附用部份，及辨識黏著性層疊體的特性用的辨識用部份，並將黏附體貼附用部份與辨識用部份平面配置在相同的剝離片上，藉此不論黏著性層疊體(黏附體貼附用部份)的形態為何，皆可明確辨識黏著性層疊體的特性。 As described in detail above, the adhesive sheet according to the present invention is formed by processing an adhesive laminate composed of a base material and an adhesive layer on a release sheet into an adhesive body attaching part for attaching to an adhesive body , And the identification part for identifying the characteristics of the adhesive laminate, and the adhesive attachment part and the identification part are arranged on the same release sheet in the same plane, so that regardless of the adhesive laminate (adhesive attachment part Whatever the form of the part), the characteristics of the adhesive laminate can be clearly recognized.
