An active energy beam-curable composition comprises an epoxy compound, an oxetane compound, a photo-cationic polymerization initiator, a pigment as a coloring agent, and a pigment dispersing agent. The pigment dispersing agent contains an active ingredient of a comb-shaped polymer in which an anchor is a base and which is liquid at room temperature. Therefore, the adhesion performance is satisfactory even on a base material such as polycarbonate on which it has been impossible to obtain any satisfactory adhesion performance with any conventional active energy beam-curable composition.
