Abstract
An actinic energy ray curable adhesive contains a urethane resin (D) and a epoxy resin (E). The urethane resin (D) is prepared by reacting a diol ingredient (A1) having no (meth)acryloyl group, an optional diol ingredient (A2) having no (meth)acryloyl group, no carbonate structure and no alicyclic structure, a polyol ingredient (B) having a (meth)acryloyl group and two or more hydroxyl groups in a molecule, and a polyisocyanate ingredient (C) together. The ingredient (A1) is selected from a diol (a1) having a carbonate structure and an alicyclic structure in a molecule, a combination of a diol (a2) having no alicyclic structure but having a carbonate structure, and a diol (a3) having no carbonate structure but having an alicyclic structure, and a combination of a diol (a1) and at least one of the diol (a2) and the diol (a3).
