Abstract
An adhesive sheet including an adhesive composition disposed on at least one face of a film of acetyl cellulose, the adhesive sheet being produced by coating a solution of the adhesive composition on the face of the film and drying the solution to form a laminate, the adhesive composition containing (A) a copolymer of (meth)acrylic esters,(B) a crosslinking agent and (C) a phenol compound. The adhesive composition in the adhesive sheet serves to suppress degradation of easily hydrolyzable materials by hydrolysis, improve durability and provides excellent stress relaxation without using plasticizers.
