PURPOSE: To obtain a non-film-forming resin emulsion which can protect the skin by screening ultraviolet rays, does not irritate the skin and excels in adhesion thereto by emulsion-polymerizing a radical-polymerizable monomer with a polymerizable unsaturated reactive ultraviolet absorber. n CONSTITUTION: The title emulsion is produced by emulsion-copolymerizing a radical-polymerizable monomer with at least one polymerizable unsaturated reactive ultraviolet absorber selected from compounds of formulas I-III, compounds of formulas V-VIII and a compound of formula IV. In the formulas, Q 1 is vinyl, a group of formula IX or 1-20C alkyl; R 1 is H, methoxy or vinyl; R 2 is amino or a group of formula X, XI or XII; R 3 is H or vinyl; R 4 is a group of formula XIII or vinyl; R 5 and R 6 are each H, methyl, isopropyl, t-butyl or methoxy; R 7 is a group of formula IX or vinyl; R 8 and R 9 are each H, methyl or vinyl; R 10 is a group of formula XIII or vinyl; R 11 is H, methyl, isopropyl, t-butyl or methoxy; R 12 and R 13 are each H, vinyl or the like; and R 14 and R 15 are each H, vinyl, 1-20C alkyl or the like. n COPYRIGHT: (C)1991,JPO&Japio |
