PURPOSE:To improve adhesion of film to metal, by using a specified compound as a reactive diluent in a composition which consists mainly of a base resin, a reactive diluent and a photopolymerization initiator and forms a film by irradiation with ultraviolet rays. CONSTITUTION:The purpose ultraviolet-curing resin composition is obtained by using a base resin (A) (e.g., polyester polyvinyl compound), a reactive diluent partially or entirely consisting of a compound (B) of formula I and a photopolymerization initiator (C) (e.g., benzophenone). By applying this composition to a substrate and irradiating it with ultraviolet rays, a film having excellent adhesion to the substrate can be formed. The compound of formula I can be advantageously produced by esterifying the spiroglycol diglycidyl ether of formula II with acrylic acid.
