Disclosed is the use of the compounds of formula (1) wherein R1 and R2 independently of one another are hydrogen; unsubstituted or substituted C1-C12 alkyl; unsubstituted or substituted C3-C12 cycloalkyl; unsubstituted or substituted C6-C20 aryl; or unsubstituted or substituted C2-C20 alkenyl; R3 is PO3R1R2; COOR6; COR7; CONR7R8; —SO2R6; CN; unsubstituted or substituted C6-C20 aryl; R4 is unsubstituted C6-C20 aryl; or C6-C20 aryl which is substituted by at least one C1-C18 alkyl, C1-C18 alkoxy, C3-C12 cycloalkyl, hydroxy, amino, mono- or di-C1-C18 alkylamino, —NR10COR11 or the radical of formula (1a) or unsubstituted or substituted C4-C20 heteroaryl; R5 is hydrogen; substituted or unsubstituted C1-C20 alkyl; unsubstituted or substituted C3-C12 cycloalkyl; unsubstituted or substituted C6-C20 aryl; or unsubstituted or substituted C4-C20 heteroaryl; or R4 and R5 form a cycloaliphatic ring; R6, R7 and R8 independently from each other are hydrogen; C1-C18 alkyl or C3-C12 cycloalkyl, which may be substituted by one or more E and/or interrupted by one or more D; or C6-C20 aryl, which may be substituted by G; or R7 and R8 together form a five or six membered ring; D is —CO—; —COO—; —S—; —SO; —SO2—; —O—; —NR9—; SiR12R13—; —POR14—; —CR15═CR16—; or —C≡C—; E is —OR17; —SR17; —NR10R11; —NR10COR11; —COR11; —COOR11; —CONR10R11; —CN; halogen; SO3R18; SO2R18; PO3 (R18)2; or PO2(R18)2; G is E; C1-C18 alkyl, which is optionally interrupted by D; C1-C18 perfluoroalkyl; C1-C18 alkoxy, which is optionally substituted by E and/or interrupted by D; wherein R9, R10 and R11, independently of each other are hydrogen; C6-C18 aryl which is optionally substituted by C1-C18 alkyl or C1-C18 alkoxy; C1-C18 alkyl, which is optionally interrupted by —O—; or R10 and R11 together form a five or six membered ring; R12 and R13 independently of each other are hydrogen; C1-C18 alkyl; or C6-C18 aryl which is optionally substituted by C1-C18 alkyl; R14 is C1-C18 alkyl; or C6-C18 aryl, which is optionally substituted by C1-C18 alkyl; R15 and R16 independently of each other are hydrogen; C6-C18 aryl which is optionally substituted by C1-C18 alkyl or C1-C18 alkoxy; or C1-C18 alkyl which is optionally interrupted by —O—; R17 is H; C6-C18 aryl which is optionally substituted by C1-C18 alkyl or C1-C18 alkoxy; or C1-C18 alkyl which is optionally interrupted by —O—; and R18 is hydrogen; C6-C18 aryl, which is optionally substituted by C1-C18 alkyl or C1-C18 alkoxy; or C1-C18 alkyl, which is optionally interrupted by —O—; for the protecting of human and animal hair and skin from UV radiation. The UV filters of the present invention represent oil-soluble substances which advantageously absorb in the UV-A and UV-B region.
