摘要

Composition comprising at least one protective system in a physiologically acceptable support, characterized by comprising: (a) at least one UV protector of the type dibenzoylmethane derivative; and (b) at least one sulfone derivative merocyanine of Formula (6): wherein: R2 represents H, an alkyl radical C1-C22, a cycloalkyl radical of C3-C8, an aryl radical of C6-C20, R3 It represents a carboxyl group, -COOR4, -CONHR4, -COR4, -CONR1R4, -CN or -SO2R4; R4, which may be identical or different, represent an alkyl radical C1-C22, a cycloalkyl radical of C3-C8 or an aryl radical of C6-C20; R, which may be identical or different, represents an alkyl radical of C1-C20 linear or branched which may be optionally halogenated, an aryl radical of C6-C12 or an alkoxy group of C1-C10; a = 0 to 3; A is a divalent radical selected from methylene, ethylene or a group having one of the following formulas (7), (8) or (9): wherein: Z is an alkylene radical of C1-C6 linear or branched, saturated or unsaturated, optionally substituted with a hydroxyl radical or an alkyl radical of C1-C8 linear or branched, saturated or unsaturated; W represents a hydrogen atom, a hydroxyl radical or an alkyl radical of C1-C8 linear or branched, saturated or unsaturated; p is 0 or 1; f = 1 or 2.
