201011081 六、發明說明：【發明所屬之技術領域】本發明係關於一種光學薄膜用黏著劑組成物、附有該黏著劑之光學薄膜、及該黏著劑組成物的製造方法，該黏著劑組成物係用於將偏光膜、相位差膜等的光學薄膜黏貼於液晶胞等被黏著物。更詳細而言，本發明係關於一種光學薄膜用黏著劑組成物、附有該黏著劑之光學薄膜、及該 # 黏著劑組成物的製造方法，該黏著劑組成物在高溫高濕下也有優良的耐久性，同時具有難以產生白缺陷（white defect)之特.性。【先前技術】液晶顯示裝置，通常是由在2片玻璃等的支撐基板之間夾有以規定方向配向之液晶成分的液晶胞、以及偏光膜參或相位差膜、亮度提升膜等光學薄膜所構成，而在將光學薄膜彼此之間予以積層、或是將光學薄膜黏貼在液晶胞上之際，大多是使用黏著劑。液晶顯示裝置被作為個人電腦或電視、衛星導航系統等的顯示裝置而使用於廣大範圍。隨之而來的則是要求有一種黏著劑，即使在高溫高濕下的嚴苛環境下使用，其耐久性仍優良，亦即，即使是長期的使用也不會發生剝落或產生氣泡等。而且，在高溫高濕下的嚴苛的環境下，光學薄膜會有很大的收縮、膨脹之類的尺寸變化，黏著劑層無 201011081 法緩和由於此尺寸變化而產生的應力，則光學薄膜的殘留應力變得不均勻。結果’光自液晶顯示裝置的周邊部泡漏而變白’而成為所謂的Γ白缺陷J的問題。為了解決此種問題，提案有一種黏著劑，其因為添加 - 低分子量聚合物於黏著劑組成物中，而具有應力緩和性。例如，在專利文獻丨（曰本特開平10_279907號公報）中，揭示有一種偏光板用黏著劑組成物，其係由高分子量丙稀酸 φ 系共聚物、重量平均分子量是3萬以下之低分子量丙烯酸系共聚物、多官能化合物所構成，並記載著該黏著劑組成物會追隨偏光板的尺寸變化而難以產生白缺陷。然而，專利文獻1所記載的黏著劑組成物，由於重量平均分子量.是 3萬以下之低分子量丙烯酸系共聚物的添加量多，所以難以防止高溫高濕下的發泡或剝落。又’專利文獻2(日本特開2006-133606號公報）揭示一種黏著劑組成物’其係由：含官能基單體〇5重量。/()以下之 • 低玻璃轉移溫度（Tg)丙烯酸系共聚物與含官能基單體6 重量％以上之高Tg丙烯酸系共聚物的混合物、以及可與官能基反應的交聯劑和異氰酸酯所構成；其凝膠分率小於30 重量％。此黏著劑組成物，是藉由在高Tg丙烯酸系共聚物的分子内形成交聯結構，並將低Tg丙烯酸系共聚物的分子間以異氰酸醋化合物之多聚體（multimer)拘束在一起，而表現凝集力。然而，此黏著劑組成物雖然藉由在分子間幾乎未形成交聯構造而難以產生白缺陷，但其在高溫下的凝集力低，在耐久性評價中難以抑制發泡或剝落的產生。 201011081 又，專利文獻3(日本特開20〇4_224873號公報）則揭示 -種黏著劑組成物’其添加〇.3〜3重量份之異氰酸酯化合物於具有羧基和羥基之丙烯酸系共聚物中，並記載著該黏著劑組成物的耐久性及白缺陷抑制性優良。此黏著劑組成 . 物，用於上述公開公報的實施例中的小型液晶顯示裝置 • 時，其耐久性及白缺陷抑制性優良。然而，用於大型液晶顯示裝置時，則耐久性及白缺陷抑制性不良，因而謀求能 • 有一種黏著劑組成物，其具有更優良的耐久性及更高水準的白缺陷抑制性。近年來，隨著液晶顯示裝置的大型化，光學薄膜的尺寸也變得較大。由於光學薄膜的尺寸越大，光學薄膜的膨脹或收縮之類的尺寸變化也會越大，所以謀求較高的耐久性及白缺陷抑制性。已揭示有一種黏著劑組成物其係一種即使用於大畫面的液晶顯示裝置也能滿足耐久性之黏著劑，且凝集力高。例如，專利文獻4(曰本特開平籲號公報）揭示有一種偏光板用黏著劑組成物，其係於以2〇 /80〜50/ 50的重量比將含有羧基或酿胺基而未含有羥基之丙烯酸系共聚物（A)、以及含有羧基或醯胺基和羥基之丙烯酸系共聚物（B)混合而成之混合物中，調配異氱酸酯化合物而成。然而，此專利文獻4所記載的黏著劑組成物，即使能抑制在高溫高濕下的發泡或剝落，也會由於應力緩和性不足而容易產生白缺陷β [專利文獻1]曰本專利特開平1〇_2799〇7號公報 [專利文獻2]日本專利特開之⑽卜〗336〇6號公報 5 201011081 [專利文獻3] [專利文獻4] 曰本專利特開2004_224873號公報曰本專利特開平9-113724號公報【發明内容】 [發明所欲解決之問題] •㈣專敎獻1〜4之黏著劑組成物，如同上述，難以提供兼具耐久性及白缺陷抑制性的光學薄膜。例如，用於籲 *有大畫面之液晶顯示裝置的光學薄膜其尺寸於近年來[Technical Field] The present invention relates to an adhesive composition for an optical film, an optical film with the adhesive, and a method for producing the adhesive composition, the adhesive composition It is used to adhere an optical film such as a polarizing film or a retardation film to an adherend such as a liquid crystal cell. More specifically, the present invention relates to an adhesive composition for an optical film, an optical film with the adhesive, and a method for producing the composition of the adhesive, which is excellent also under high temperature and high humidity. Durability, while having the difficulty of producing white defects. [Prior Art] A liquid crystal display device in which a liquid crystal cell having a liquid crystal component aligned in a predetermined direction is interposed between support substrates such as two sheets of glass, and an optical film such as a polarizing film or a retardation film or a brightness enhancement film is usually used. In the configuration, when the optical films are laminated to each other or the optical film is adhered to the liquid crystal cells, an adhesive is often used. The liquid crystal display device is used in a wide range as a display device such as a personal computer, a television, or a satellite navigation system. Along with this, an adhesive is required, which is excellent in durability even in a severe environment under high temperature and high humidity, that is, it does not peel off or generate bubbles even after long-term use. Moreover, under the severe environment of high temperature and high humidity, the optical film has a large dimensional change such as shrinkage and expansion, and the adhesive layer does not have the 201011081 method to alleviate the stress due to the dimensional change, and the optical film is The residual stress becomes uneven. As a result, "light is bubbled from the peripheral portion of the liquid crystal display device and becomes white", which is a problem of the so-called chalkiness defect J. In order to solve such a problem, it is proposed to have an adhesive which has stress relaxation property by adding a low molecular weight polymer to the adhesive composition. An adhesive composition for a polarizing plate, which is composed of a high molecular weight acrylic acid φ-based copolymer and having a weight average molecular weight of 30,000 or less, is disclosed in Japanese Laid-Open Patent Publication No. Hei 10-279907. It is composed of a molecular weight acrylic copolymer or a polyfunctional compound, and it is described that the adhesive composition tends to follow the dimensional change of the polarizing plate and is less likely to cause white defects. However, in the adhesive composition described in Patent Document 1, since the amount of the low molecular weight acrylic copolymer having a weight average molecular weight of 30,000 or less is large, it is difficult to prevent foaming or peeling under high temperature and high humidity. Further, Patent Document 2 (JP-A-2006-133606) discloses an adhesive composition which is composed of a functional group-containing monomer 〇5 by weight. /() below • a mixture of a low glass transition temperature (Tg) acrylic copolymer and a high Tg acrylic copolymer containing more than 6% by weight of the functional group monomer, and a crosslinking agent and isocyanate reactive with the functional group Composition; its gel fraction is less than 30% by weight. The adhesive composition is formed by forming a crosslinked structure in the molecule of the high Tg acrylic copolymer, and binding the molecules of the low Tg acrylic copolymer to the multimer of the isocyanate compound. Together, it shows agglutination. However, this adhesive composition is less likely to cause white defects by forming a crosslinked structure between molecules, but its cohesive force at a high temperature is low, and it is difficult to suppress the occurrence of foaming or peeling in durability evaluation. Further, Patent Document 3 (Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei.

This adhesive composition is excellent in durability and white defect suppressability when used in the small liquid crystal display device of the embodiment of the above publication. However, when it is used in a large-sized liquid crystal display device, durability and white defect suppression are poor, and therefore it is possible to have an adhesive composition which has more excellent durability and a higher level of white defect suppressing property. In recent years, with the increase in size of liquid crystal display devices, the size of optical films has also become large. Since the size of the optical film is larger, dimensional changes such as expansion or contraction of the optical film are also increased, so that high durability and white defect suppressing properties are obtained. An adhesive composition which is an adhesive which satisfies durability even in a liquid crystal display device for a large screen has been disclosed, and has high cohesive force. For example, Patent Document 4 (Japanese Unexamined Patent Publication Publication No. Publication No. Publication No.---------------- An isophthalic acid ester compound is prepared by mixing a hydroxy acrylic copolymer (A) and a mixture of a carboxyl group or a hydrazide group and a hydroxyl group-containing acrylic copolymer (B).

Invention name: (Chinese) Adhesive composition, optical film and adhesive composition manufacturing method Weng II, Chinese invention Abstract: The object of the present invention is to provide an adhesive composition for an optical film and an optical film with an adhesive for adhering an optical film, even in a high-temperature and high-humidity environment. It also has excellent durability and can suppress the generation of white defects. The present invention is an adhesive composition comprising: an acrylic copolymer containing a reactive functional group; and 5 parts by weight or more based on 1 part by weight of the acrylic copolymer (A) 3 parts by weight or less of the Φ-based ester compound (B). III. SUMMARY OF THE INVENTION Abstract: The present invention relates to an adhesive composition for an optical film, an optical film with the adhesive, and a method for producing the adhesive composition. The adhesive composition is used to adhere an optical film such as a polarizing film or a retardation film to an adherend such as a liquid crystal cell. More specifically, the present invention relates to an adhesive composition for an optical film, an optical film with the adhesive, and a method for producing the adhesive composition, which has a high temperature and high humidity. Excellent durability and at the same time it is difficult to produce white defects. [Prior Art] A liquid crystal display device is usually composed of a liquid crystal cell in which a liquid crystal component is aligned in a predetermined direction between a support substrate such as two sheets of glass, and an optical film such as a polarizing film, a retardation film, or a brightness enhancement film. When the optical films are laminated to each other or the optical film is adhered to the liquid crystal cells, an adhesive is often used. The liquid crystal display device is used in a wide range as a display device such as a personal computer or a television or a satellite navigation system. What follows is the requirement for an adhesive that is excellent in durability even in harsh environments with high temperatures and high humidity, ie, no peeling or gas generation even for long-term use. Wait. Moreover, under the severe environment of high temperature and high humidity, the optical film s has a large dimensional change such as shrinkage and expansion, and the adhesive layer has no 201011081 method to alleviate the stress caused by this dimensional change. ", the film remains, and the peripheral portion of the liquid display device is whitened and turned white, which is a problem of so-called "white defects."丨丨鲁 This problem has a proposal for an adhesive, which is stress-relieving because of the addition of a knife to the adhesive composition. For example, in the patent document 丨 (Japanese Patent Laid-Open No. 1 〇〇 799 〇胄胄胄 ) ) ) ) ) ) ) 揭示揭示揭示揭示揭示揭示揭示揭示偏偏偏偏偏偏偏偏偏偏偏偏偏偏偏偏偏偏偏偏It is composed of a low molecular weight acrylic acid copolymer or a polyfunctional compound of 10,000 or less, and it is described that the adhesive composition tends to follow the dimensional change of the polarizing plate, and it is difficult to cause white defects. However, in the adhesive composition described in Patent Document 1, since the addition amount of the low molecular weight acrylic copolymer having a weight average molecular weight of 30,000 or less is large, it is difficult to prevent foaming or peeling under high temperature and high humidity. Further, Patent Document 2 (JP-A-6-11-3606) discloses an adhesive composition which is composed of a functional group-containing monomer 〇 5 weight. /. a low glass transition temperature (Tg) acrylic-based well polymer and a mixture of a high Tg acrylic copolymer containing 6 wt% or more of a functional group-containing monomer, and a crosslinker and an isocyanate reactive with a functional group; The gel fraction is less than 30% by weight. The adhesive composition is formed by forming a crosslinked structure in a molecule of a high Tg acrylic copolymer and interposing a molecule of a low Tg acrylic copolymer with a multimer of an isocyanate compound. Performance agglutination. However, this adhesive composition is difficult to produce white defects by forming almost no crosslinked structure between molecules, but its cohesive force at a high temperature is low, and it is difficult to suppress the occurrence of foaming or peeling in the evaluation of durability. Further, Patent Document 3 (JP-A-2004-224873) discloses an adhesive composition in which 0.3 to 3 parts by weight of an isocyanate compound is added to an acrylic copolymer having a carboxyl group and a hydroxyl group, and the adhesive is described. The composition is excellent in durability and white defect suppressing property. When the adhesive composition is used in the small liquid crystal display device of the examples disclosed in the above publication, it is excellent in durability and white defect suppressing property. However, when it is used in a large-sized liquid crystal display device, durability and white defect suppressability are poor, so that it is possible to have an adhesive composition which has more excellent durability and a higher level of white defect suppressing property. In recent years, with the increase in size of liquid crystal display devices, the size of optical films has also become large. Since the size of the optical film is larger, dimensional changes such as expansion or contraction of the optical film are also increased, so that high durability and white defect suppressing properties are obtained. There has been disclosed an adhesive composition which is an adhesive which satisfies durability even in a liquid crystal display device for a large screen, and has high cohesive force. For example, Patent Document 4 (Japanese Unexamined Patent Publication No. Hei No. Hei No. Hei No. Hei No. Hei No. Hei 9-113) discloses an adhesive composition for a polarizing plate which is contained in a weight ratio of 20 / 80 to 50 / 50 and which contains a carboxyl group or a mercapto group. An isocyanate compound is prepared by mixing an acrylic copolymer (A) having no hydroxyl group and an acrylic copolymer (B) containing a carboxyl group or a mercapto group and a hydroxyl group. However, the adhesive composition described in Patent Document 4 can easily cause white defects due to insufficient stress relaxation properties even if foaming or peeling under high temperature and high humidity can be suppressed.
