An adhesive composition comprising (A) a copolymer ofn(meth)acrylic esters, (B) a crosslinking agent and (C) a phenol derivative;nan adhesive composition comprising (D) a copolymer of (meth)acrylic estersnhaving a weight-average molecular weight (Mw) of 500,000 to 2,500,000 orn(D') a mixture of the copolymer (D) and an oligomer of (meth)acrylic estersnhaving Mw of 1,000 to 10,000 (100:5 to 100:100 by weight), (E) ancrosslinking agent and (F) a radical scavenger; and an adhesive opticalncomponent comprising a layer of the adhesive composition disposed atnleast on one face of an optical component. n Degradation of easily hydrolyzable materials by hydrolysis isnsuppressed and durability is improved by application of the formerncomposition. Excellent stress relaxation is provided without plasticizersnand degradation of an easily hydrolyzable material by hydrolysis andndegradation of the composition itself are suppressed by application of thenlatter composition. |
