Composition of Claim 1, wherein dibenzoylmethane derivative is 4-isopropyldibenzoylmethane. 5. Composition of any Claim 1-4, wherein dibenzoylmethane derivative is present in composition in quantity from 0,1 to 8% by weight as per total mass of the composition. 6. Composition of Claim 5, wherein dibenzoylmethane derivative is present in composition in quantity from 0,2 to 5% by weight as per total mass of the composition. .7. Composition of any Claim 1-6, wherein alkyl-β, β'-diphenylacrylate derivative is selected from 2-ethylhexyl-α-cyano-β, β'-diphenylacrylate and ethyl α-cyano-β, β'-diphenylacrylate. 8. Composition of any Claim 1-6, wherein alkyl-β, β'-diphenylacrylate derivative is 2-ethylhexyl-α-cyano-β,β'-diphenylacrylate. 9. Composition of any Claim 1-8, wherein alkyl-β, β'-diphenylacrylate derivative is present in composition in quantity from 0.1 to 20% by weight as per total mass of the composition. 10. Composition of Claim 9, wherein alkyl-β, β'-diphenylacrylate derivative is present in composition in quantity from 0.1 to 20% by weight as per total mass of the composition. 11. Composition of any Claim 1-10, wherein benzotriazole is selected from compounds of general formula (1) in which radicals B are selected from radicals R. 12. Composition of Claim 11, wherein benzotriazole is selected from compounds having, at least, one the following characteristics: -R is alkyl and more preferably methyl; -r is an integer from 0 to 15 inclusively; -s is an integer from 1 to 10 inclusively; -n is not nil and preferably 1; and Y is selected from methyl, tret-butyl or alkoxy having 1-4 carbon atoms -Z is hydrogen of methyl; -m is 0 or (m=1 and X=0); -p is 1. 13.
