PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND ADHESIVE SHEET AND ADHESIVE OPTICAL COMPONENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a pressure-sensitive adhesive composition having both of durability and light leak-preventing properties; and to prepare an adhesive sheet and to provide an adhesive optical member using the adhesive composition.

SOLUTION: The pressure-sensitive adhesive composition contains (i) a copolymer (A) obtained by copolymerizing a (meth)acrylic ester with a functional group-containing monomer, and (ii) a copolymer (B) obtained by copolymerizing the (meth)acrylic ester with a radically polymerizable monomer having an isocyanate group in the molecule. The adhesive sheet and the adhesive optical member use the adhesive composition.
