<p>PROBLEM TO BE SOLVED: To provide an active energy ray-curable adhesive composition for a plastic film or the like which has low viscosity, excellent curability, excellent adhesion to various plastic films even if the atmospheric humidity during coating and curing is high, and excellent colorless transparency.SOLUTION: There is provided an active energy ray-curable adhesive composition for a plastic film or a sheet comprising the following components (A) to (D) as essential components. Component (A): a polymer which is obtained by polymerization of (a1) a compound having an epoxy group and an ethylenically unsaturated group and (a2) a compound having an ethylenically unsaturated group other than the (a1) compound and has a glass transition temperature of 20°C or more and a weight average molecular weight of 1000 to 30000, Component (B): a polyglycidyl ether of a polyol having 2 to 10 carbon atoms, Component (C): a compound having an alicyclic epoxy group and a molecular weight of 500 or less, and Component (D): a photo-cationic polymerization initiator.</p> |
