ULTRAVIOLET RAY-CURABLE ADHESIVE AGENT COMPOSITION, ADHESIVE FILM, AND PRODUCTION METHOD FOR ADHESIVE FILM

摘要

The present invention addresses the issue of providing an ultraviolet ray-curable adhesive agent composition whereby an adhesive film having excellent conformability to level differences and excellent cutting properties can be obtained. The present invention provides an ultraviolet ray-curable adhesive agent composition characterized by containing a urethane (meth) acrylate (A), a photopolymerizable initiator (B), and an organic solvent (C), said urethane (meth) acrylate (A) being obtained by reacting: a polyol composition (a1) including both a chain extender (a1-1) having a hydroxyl group and other polyols, said polyol composition (a1) having a hydroxyl group equivalent of no more than 400 g/eq; a polyisocyanate (a2); and a (meth) acrylic compound (a3) having an isocyanate group or a hydroxyl group. In addition, the present invention provides an adhesive film characterized by being obtained by drying and ultraviolet-irradiating said ultraviolet ray-curable adhesive agent composition.
