Abstract UV filter combinations comprising benzylidene malonates Disclosed is the use of a UV filter combination, comprising (a) a first UV filter selected from benzylidene malonates of formula , wherein Ri methyl ethyl propyl or n-butyl if ^ is methyl, then R is tert. butyl ■ a radical of formula (1a) radical of forumula (1b) wherein R2 and R3, independently from each other are hydrogen or methyl R4 is methyl ethyl or n-propyl R5 and R6 independently from each other are hydrogen or C1-C3alkyl if R1 is ethyl propyl or n-butyl, then R is isopropyl and (b) a second UV filter selected from (b-i) Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (b2) Butyl Methoxydibenzoylmethane (b3) Diethylhexyl Butamido Triazone (b4) Ethylhexyl Triazone (b5) Diethylamino Hydroxy Benzoyl Hexyl Benzoate (b6) Ethylhexyl Methoxycinnamate (b7) Ethylhexyl Salicylate (b8) Homosalate (b9) Octocrylene (b10) micronized Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (b-i-i) Phenylbenzimidazole Sulfonic Acid (bi2) Titanium Dioxide (b13) micronized Tris-Biphenyl Triazine and (b14) micronized (2-{4-[2-(4-Diethylamino-2-hydroxy-benzoyl)-benzoyl]-piperazine-1- carbonyl}-phenyl)-(4-diethylamino-2-hydroxy-phenyl)-methanone (bi5) benzoic acid,4,4-[[3-[1,3,3,3-tetramethyl-1 -[trimethylsilyl)oxy]-1 -disiloxanyl]pro- pyl]amino]-1,3,5-triazine-2,4-diyl]diimino]bis-, dibutyl ester wherein the UV filter combination comprises at least 2 UV filters of component
