Use of new and known bicyclic and tricyclic enamines as UV filters in cosmetic and pharmaceutical preparations is new. Also new is their use for the protection of plastics. Use of bicyclic and tricyclic enamines as UV filters in cosmetic and pharmaceutical preparations is new. R<1> and R<2> = CN; alkylcarbonyl; alkoxycarbonyl; aryloxycarbonyl; or optionally substituted aminocarbonyl; R<3> = H; 1-20C alkyl; 3-20C cycloalkyl; or -CH2-CH2-SO3<->M<+>; M<+> = cation; X = -O-; -S-; or -N(R<3>)-; Z' = group of formula (ii) or (iii): R<4> = H; alkyl, cycloalkyl, alkoxy, cycloalkoxy, alkoxycarbonyl, alkyl-NH-CO-, (alkyl)2-NH-CO-, alkyl-NH- or (alkyl)2N- (each with up to 20C); CN; NH2; or SO3<->M<+> and more than 1 R<4> can be present. Independent claims are also included for: (1) the use of compounds (I) as light screening agents for the protection of plastics; (2) (I; Z' = (iii); and (3) (I; Z' = (ii); R4 = R40; R1, R2 = R10, R20 respectively) R<10> and R<20> = CN or 2-10C alkoxycarbonyl optionally substituted with -(CH2)n-SO3<->M<+>; R<30> = H; CH3; or -(CH2)n-SO3<->M<+>; R<40> = H; 1-8C alkyl; 1-8C alkoxy; or -SO3<->M<+>; n = 2 or 3; M = H or HN(R<5>)(R<6>)(R<7>)<+>; R<5>-R<7> = H lower alkyl optionally substituted with OH; or a metal cation; but at least one -(CH2)n-SO3<->M<+> or -SO3<->M<+> must be present. |
