<P>PROBLEM TO BE SOLVED: To provide an adhesive composition which causes neither cloudiness of an adhesive layer nor lifting and peeling of the adhesive layer from an adherend when durability test is conducted with the use of an oven under environmental conditions at a high temperature and high humidity is conducted and even after taken out of the oven, and also to provide an adhesive film. <P>SOLUTION: A process for producing an adhesive composition including an acrylic polymer containing a hydroxyl group as a functional group comprises (1) obtaining a main agent polymer with the use of a mixed solvent solution containing at least one of an acrylic monomer, (2) thereafter preparing an adhesive raw material composition containing the main agent polymer, at least one monomer of a hydroxyl group-containing (meth)acrylate, a photopolymerization initiator, and a difunctional crosslinking agent in an amount of not greater than 0.1 equivalent amount per crosslinking point of the polymer, and (3) subjecting the adhesive raw material composition to polymerization reaction by photoirradiation and crosslinking reaction by aging to obtain the adhesive composition. <P>COPYRIGHT: (C)2011,JPO&INPIT |
