ACTIVE ENERGY RAY-CURABLE RESIN COMPOSITION AND USE THEREOF

摘要

[PROBLEMS] To provide a resin composition which can be cured with an active energy ray such as ultraviolet ray or the like to form a stiff film or molded material. [MEANS FOR SOLVING PROBLEMS] Disclosed is an active energy ray-curable resin composition which is a phenol-aralkyl type epoxy resin having a structure to which at least a glycidoxybenzene or a glycidoxynaphthalene is bound through an aralkyl group as a bond and a structure of the formula (1): (1) and comprises an epoxy resin (A) satisfying the requirement shown by the formula (a) below and a compound (B) having an unsaturated double bond that can react by irradiation with an active energy ray: 100 = (X/Y)xZ = 1100 ··· (a) wherein X (g/eq.) represents a hydroxyl equivalent of the phenol-aralkyl type epoxy resin; Y (g/eq.) represents an epoxy equivalent of the epoxy resin; and Z (ºC) represents a softening point of the epoxy resin.
