Description
本発明は粘着シートに関する。 The present invention relates to an adhesive sheet.
従来、携帯電話やタッチパネル等の液晶表示装置においては、表示画面に関する液晶表示モジュールユニットとバックライトユニットとの間に、遮光性層を有する粘着シートが用いられている。上記遮光性層はバックライト光が液晶表示モジュール側に漏れることを防ぎ、視認性を向上する効果を発揮する。 Heretofore, in liquid crystal display devices such as mobile phones and touch panels, a pressure-sensitive adhesive sheet having a light shielding layer is used between a liquid crystal display module unit related to a display screen and a backlight unit. The light shielding layer prevents the backlight light from leaking to the liquid crystal display module side, and exhibits the effect of improving the visibility.
このような遮光性層を備えた粘着シートとして、プラスチック基材上に黒色の印刷層を設けた積層基材に粘着剤層を設けた構成が知られている（例えば、特許文献１参考）。 As an adhesive sheet provided with such a light shielding layer, the structure which provided the adhesive layer in the lamination | stacking base material which provided the black printing layer on the plastic base material is known (for example, refer patent document 1).
上記のような粘着シートに用いられる積層基材では、通常、印刷層とプラスチック基材との接着性を向上させるため、印刷層とプラスチック基材との間にプライマー層を設ける。しかし、プライマー層は、その表面が平滑ではないため、その上に積層される印刷層の厚さにバラツキが生じ得る。このため、使用形態によっては、印刷層が薄い部分から光が漏れる場合がある。 In the laminated substrate used for the above-mentioned adhesive sheet, in order to improve the adhesiveness of a printing layer and a plastic substrate, a primer layer is usually provided between a printing layer and a plastic substrate. However, since the surface of the primer layer is not smooth, variations may occur in the thickness of the printing layer laminated thereon. For this reason, depending on the use form, light may leak from the thin portion of the print layer.
そこで本発明の目的は、プライマー層を設けた場合であっても、粘着特性を悪化させることなく、遮光性により優れた粘着シートを提供することにある。 Therefore, an object of the present invention is to provide a pressure-sensitive adhesive sheet which is more excellent in the light shielding property without deteriorating the adhesion property even when the primer layer is provided.

The primer layer is characterized by containing a colorant.
ここに開示される粘着シートにおいては、上記プライマー層における着色剤の含有量が０．０１〜６０重量％であることが好ましい。 In the pressure-sensitive adhesive sheet disclosed herein, the content of the colorant in the primer layer is preferably 0.01 to 60% by weight.
また、ここに開示される粘着シートにおいては、上記着色層が黒色であることが好ましい。 In the pressure-sensitive adhesive sheet disclosed herein, the colored layer is preferably black.
さらには、ここに開示される粘着シートにおいては、上記着色剤が黒色であることが好ましい。 Furthermore, in the pressure-sensitive adhesive sheet disclosed herein, the colorant is preferably black.
また、ここに開示される粘着シートにおいては、上記粘着剤層が、アクリル系粘着剤から形成された粘着剤層であることが好ましい。 In the pressure-sensitive adhesive sheet disclosed herein, the pressure-sensitive adhesive layer is preferably a pressure-sensitive adhesive layer formed of an acrylic pressure-sensitive adhesive.
本発明によると、プライマー層を設けた場合であっても、粘着特性を悪化させることなく、遮光性により優れた粘着シートを提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, even when it is a case where a primer layer is provided, the adhesive sheet excellent by light-shielding property can be provided, without deteriorating an adhesion characteristic.

温度計、攪拌機、窒素導入管および環流冷却管を備えた反応器に、アクリル酸ｎ−ブチル７０重量部、アクリル酸２−エチルヘキシル２７重量部、アクリル酸３重量部、アゾビスイソブチロニトリル０．２重量部および重合溶媒として酢酸エチル２３５重量部を投入し、窒素ガスを導入しながら１時間攪拌した。このように、重合系内の酸素を除去した後、６３℃に昇温し、１０時間反応させた。その後、室温まで冷却し、固形分濃度３０重量％のアクリル系ポリマー溶液を得た。このアクリル系ポリマー溶液１００重量部（固形分換算）に４官能エポキシ系架橋剤（三菱ガス化学社製「テトラッドＣ」）０．０５重量部を加え、透明なアクリル系粘着剤を調製した。
Example 1
(Acrylic adhesive)
70 parts by weight of n-butyl acrylate, 27 parts by weight of 2-ethylhexyl acrylate, 3 parts by weight of acrylic acid, 0 parts of azobisisobutyronitrile, in a reactor equipped with a thermometer, a stirrer, a nitrogen introducing pipe and a reflux condenser .2 parts by weight and 235 parts by weight of ethyl acetate as a polymerization solvent were charged, and the mixture was stirred for 1 hour while introducing nitrogen gas. Thus, after removing oxygen in the polymerization system, the temperature was raised to 63 ° C., and the reaction was carried out for 10 hours. Thereafter, it was cooled to room temperature to obtain an acrylic polymer solution having a solid concentration of 30% by weight. A transparent acrylic adhesive was prepared by adding 0.05 parts by weight of a tetrafunctional epoxy-based crosslinking agent ("Tetrad C" manufactured by Mitsubishi Gas Chemical Co., Ltd.) to 100 parts by weight (in terms of solid content) of this acrylic polymer solution.
（両面粘着テープ）
透明ポリエチレンテレフタレート（ＰＥＴ）フィルム（東レ社製「ルミラー」）（厚さ：４．５μｍ）の一方の面に、着色プライマー組成物（黒色インク（大日精化工業社製「ＮＢ−３００墨」）とウレタン系樹脂とを３０：７０の混合比で混合したもの)をグラビア印刷法により塗布してプライマー層を形成した。
(Double-sided adhesive tape)
On one side of a transparent polyethylene terephthalate (PET) film (“Lumirror” manufactured by Toray Industries, Inc.) (thickness: 4.5 μm), a colored primer composition (black ink (“NB-300 black” manufactured by Dainichi Seika Kogyo Co., Ltd.) And a urethane resin were mixed at a mixing ratio of 30:70 by a gravure printing method to form a primer layer.
上記プライマー層の上に、黒色インク（大日精化工業社製「ＮＢ−３００墨」）を、グラビア印刷法により５回重ね塗りして、総厚さ５μｍの黒色印刷層（５層）を着色層として形成し、透明ＰＥＴ基材／プライマー層／黒色印刷層（５層）の積層構成の積層体（厚さ：１０μｍ）を得た。 A black ink ("NB-300 ink" manufactured by Dainichi Seika Kogyo Co., Ltd.) is overcoated five times by the gravure printing method on the above primer layer to color a black print layer (five layers) having a total thickness of 5 μm. It formed as a layer and obtained the layered product (thickness: 10 micrometers) of layered composition of transparent PET base material / primer layer / black printing layer (5 layers).
この積層体の両面に上記アクリル系粘着剤を粘着剤層の厚さが１０μｍとなるように塗布し、厚さ３０μｍの両面粘着テープを得た。 The acrylic pressure-sensitive adhesive was applied to both sides of this laminate so that the thickness of the pressure-sensitive adhesive layer was 10 μm, to obtain a double-sided pressure-sensitive adhesive tape with a thickness of 30 μm.
〔比較例１〕
プライマーに顔料を添加していないこと以外は実施例１と同様の操作を行い、両面粘着テープを得た。
Comparative Example 1
The same operation as in Example 1 was carried out except that no pigment was added to the primer, to obtain a double-sided pressure-sensitive adhesive tape.
（光漏れ評価）
実施例１、比較例１で得た両面粘着テープについて、下記のように評価を行った。
評価方法：暗室でＬＥＤランプ（２０Ｗ）を高さ２０ｃｍの筒（直径７５ｍｍ）の下部にセットし、筒上部に得られた両面粘着テープを置く。ＬＥＤランプを照射した際に両面粘着テープから光漏れが発生しないかどうかを目視で確認する。
(Light leak evaluation)
The double-sided pressure-sensitive adhesive tapes obtained in Example 1 and Comparative Example 1 were evaluated as follows.
Evaluation method: An LED lamp (20 W) is set in the lower part of a 20 cm high cylinder (diameter 75 mm) in a dark room, and the double-sided adhesive tape obtained is placed on the upper part of the cylinder. When irradiating the LED lamp, visually check whether light leakage occurs from the double-sided adhesive tape.
その結果、比較例１で得られたテープでは、直径約０．５ｍｍ以上の光漏れが肉眼で確認されたが、実施例１で得られたテープでは、肉眼で判断できる光漏れはなかった。 As a result, in the tape obtained in Comparative Example 1, light leakage with a diameter of about 0.5 mm or more was observed with the naked eye, but in the tape obtained in Example 1, there was no light leakage that could be judged with the naked eye.
