ADHESIVE COMPOSITION FOR POLARIZING PLATE, POLARIZING PLATE WITH ADHESIVE, AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition for a polarizing plate, which can reduce an ageing time while maintaining a sufficient pot life and which is excellent in durability.SOLUTION: The adhesive composition for a polarizing plate comprises: a (meth)acrylic copolymer including a structural unit derived from a monomer having a hydroxyl group, with a content percentage of 0.5 mass% to 8 mass%, and a structural unit derived from an alkyl (meth)acrylate; and a polyvalent isocyanate compound having a partial structure derived from an aromatic diisocyanate compound and an isocyanurate cyclic structure; and an N-substituted imidazole compound having a specific structure. In the composition, the content of the polyvalent isocyanate compound and the content of the N-substituted imidazole compound are 0.01 parts by mass to 0.3 parts by mass and 0.02 parts by mass to 0.2 parts by mass, respectively, with respect to 100 parts by mass of the (meth)acrylic copolymer.
