The use is described of merocyanine derivatives of formula (1), wherein R1 and R2 are each independently of the other hydrogen; C1-C22alkyl; cyclo-C3C8alkyl; or unsubstituted or C1-C5alkyl- or C1-C5alkoxy-substituted C6-C20aryl; orl; or R1 and R2 together with the nitrogen atom linking them form a -(CH2)m- ring which is uninterrupted or. interrupted by -O- or by -NH-; R3 is a cyano group; -COOR5; -CONHR5; -COR5; or -SO2R5; R4 is a cyano group; -COOR6; -CONHR6; -COR6; or -SO2R6; R5 and R6 are each independently of the other C1-C22alkyl; or unsubstituted or C1-C 5alkyl substituted C6-C 20aryl; or R3 and R4 together or R5 and R6 together form a 5- to 7-membered, monocyclic, carbocyclic or heterocyclic ring; Z1, and Z2 are each independently of the other a -(CH2),- group which is uninterrupted or interrupted by -O-, -S-, or by -NR7-, and/or is unsubstituted or substituted by C,1-C 5 alkyl; R7 is C1C5alkyl; I is from 1 to 4; m is from 1 to 7; n is from 1 to 4; when n = 2, R1, R 5 or R6 is a bivalent alkyl group; or R1, and R2 together with the 2 nitrogen atoms linking them form a -(CH2)m- ring; when n = 3, R1, R5 or R6 is a trivalent alkyl group; when n = 4, R1, R5 or R6 is a tetravalent alkyl group; and R1, and R2 in formula (1) are not simultaneously hydrogen, in protecting human and animal hair and skin from UV radiation.
本发明描述了公式(1)的merocyanine衍生物的用途,其中R1和R2分别独立地为氢;C1-C22烷基;环C3C8烷基;或未取代或C1-C5烷基或C1-C5烷氧基取代的C6-C20芳基;或R1和R2与连接它们的氮原子一起形成一个-(CH2)m-环,该环未中断或被-O-或-NH-中断;R3是氰基;-COOR5;-CONHR5;-COR5;或-SO2R5;R4是氰基;-COOR6;-CONHR6;-COR6;或-SO2R6;R5和R6分别独立地为C1-C22烷基;或未取代或C1-C5烷基取代的C6-C20芳基;或R3和R4一起或R5和R6一起形成一个5-至7-成员的单环、环碳氢化合物或杂环;Z1和Z2分别独立地为未中断或被-O-、-S-或-NR7-中断的-(CH2)-基团,并且/或未取代或取代为C1-C5烷基;R7是C1-C5烷基;I为1至4;m为1至7;n为1至4;当n = 2时,R1、R5或R6为二价烷基;或R1和R2与连接它们的2个氮原子一起形成一个-(CH2)m-环;当n = 3时,R1、R5或R6为三价烷基;当n = 4时,R1、R5或R6为四价烷基;并且在公式(1)中R1和R2不能同时为氢,用于保护人类和动物的头发和皮肤免受紫外线辐射的影响。
