| description | To provide a polarizing plate with an adhesive layer that, in addition to conventional required performance including durability, display unevenness resistance, and reworkability, can satisfy wet heat whitening resistance and crystal deposition prevention performance, which are required when an adhesive is used for a polarizing plate using a protective film other than a TAC film.SOLUTION: A polarizing plate with an adhesive layer has an adhesive layer (X) that is formed of an adhesive composition containing an acrylic resin (A) obtained by copolymerizing a copolymerizable component including a hydroxyl group monomer, a carboxyl group-containing monomer, and an amide group-containing monomer, an ionic compound (B), and an isocyanate cross-linking agent (C). The polarizing plate with an adhesive layer has a layer structure including the adhesive layer (X), a protective film (Y), a polarizer, and a protective film (Z). The protective film (Y) is a triacetylcellulose film. The protective film (Z) is one selected from a cycloolefin film, a polyester film, and an acrylic film.SELECTED DRAWING: None
【課題】 耐久性、耐表示ムラ性、リワーク性といった従来からの要求性能に加えて、ＴＡＣフィルム以外の保護フィルムを使用した偏光板に用いる場合に必要となる、耐湿熱白化性、更には結晶析出抑制性能をも満足することができる粘着剤層付偏光板を提供することを目的とする。【解決手段】 水酸基モノマーとカルボキシル基含有モノマーとアミド基含有モノマーを含む共重合性成分を共重合してなるアクリル系樹脂（Ａ）とイオン性化合物（Ｂ）とイソシアネート系架橋剤（Ｃ）を含有する粘着剤組成物からなる粘着剤層（Ｘ）を有する粘着剤層付偏光板であり、粘着剤層（Ｘ）／保護フィルム（Ｙ）／偏光子／保護フィルム（Ｚ）の層構成を有し、保護フィルム（Ｙ）がトリアセチルセルロール系フィルム、保護フィルム（Ｚ）がシクロオレフィン系フィルム、ポリエステル系フィルム及びアクリル系フィルムから選ばれる１種であることを特徴とする粘着剤層付偏光板。【選択図】 なし |
