Abstract

PURPOSE: To form a cured film having an excellent matte surface, by adding a benzophenone compd. and an aminobenzoate ester as photopolymerization initiators to a known ultraviolet curing resin compsn. and irradiating the mixture with ultraviolet light having a specified wave range.
CONSTITUTION: 0.1W15wt% benzophenone compd. (A) such as benzophenone and 0.1W15wt% aminobenzoate ester compd. (B) of the formula (wherein R1, R2 are each a 1W3C alkyl; R3 is a 1W12C alkyl) such as amyl p-dimethylaminobenzoate as photopolymerization initiators are added to a compsn. contg. an ultraviolet curing acrylate prepolymer such as an acrylic polyurethane and a reactive diluent such as 1,6-hexanediol diacrylate. The resulting compsn. is irradiated with ultraviolet light having a wave range of 180W600nm. There can be obtd. a cured film having an excellent matte surface without adding any matting agents. Components A and B are used in a proportion such that A≥B (by weight).
