Abstract
An adhesive composition comprising a crosslinked product of (A) a copolymer of (meth)acrylic esters and (B) a crosslinking agent, and (C) a phenol derivative. An adhesive composition comprising a crosslinked product of (D) a copolymer of (meth)acrylic esters having a weight-average molecular weight of 500,000 to 2,500,000 or (D′) a mixture of the copolymer (D) and an oligomer of (meth)acrylic esters having a weight-average molecular weight of 1,000 to 10,000 in a ratio of amounts of 100:5 to 100:100 by weight and (E) a crosslinking agent, and (F) a radical scavenger. An adhesive optical component comprising a layer of the adhesive composition disposed on at least one face of an optical component. The adhesive composition serves to suppress degradation of easily hydrolyzable materials by hydrolysis, improve durability and provide excellent stress relaxation without plasticizers.
