ABSTRACT:
A process for producing adhesive film comprising coating on a filmlike substrate a composition comprising (i) a copolymer having a glass transition temperature of -30.degree. C. or lower and obtained from one or more monomers (a) such as alkyl acrylates or methacrylates, or the like, and another monomers (b) containing at least one carboxyl, alcoholic hydroxyl, or glycidyl group, (ii) a crosslinking agent having at least two crosslinkable functional groups which can react with the monomers (b), (iii) one or more monofunctional addition polymerizable monomers having a boiling point of 200.degree. C. or higher, (iv) one or more polyfunctional addition polymerizable monomers having a boiling point of 200.degree. C. or higher, and (v) a photochemical initiator, and irradiating said composition with actinic light, is advantageous in that the amount of solvent to be removed after coating the composition on the substrate can be reduced remarkably without lowering properties of the resulting adhesive film.
