Claim:
A polysubstituted s-triazine compound having the following formula (I): in which the radicals R 1 , R 2 and R 3 , which may be identical or different, are each a saturated or unsaturated and linear or branched C 1 -C 10 alkyl radical optionally substituted with one or more halogen atoms, or a phenyl radical; p is equal to 0 or 1; A is hydrogen, a saturated or unsaturated and linear or branched C 1 -C 8 alkyl radical, a phenyl radical, a Si(CH 3 ) 3 group, with the proviso that, when A is Si(CH 3 ) 3 , then p=0 and R 1 , R 2 and R 3 are each methyl radicals; W is a saturated or unsaturated and linear or branched C 1 -C 8 alkylene radical optionally substituted by a hydroxyl group; Z is —(C═O)OR 4 , —(C═O)R 5 , —(C═O)NR 6 R 7 , —SO 2 R 8 , —CN or —(C═O)YCHA(W) p SiR 1 R 2 R 3 ; the R 4 radical is hydrogen, a saturated or unsaturated and linear or branched C 1 -C 20 alkyl radical; the R 5 radical is a linear or branched, optionally cyclic, C 1 -C 20 alkyl radical, or a C 6 -C 12 aryl radical; the R 6 and R 7 radicals, which may be identical or different, are each hydrogen, or a linear or branched C 1 -C 20 alkyl radical; Y is —O— or —NR 7 —; the R 8 radical is a linear or branched C 1 -C 20 alkyl radical, or a C 6 -C 12 aryl radical; and B 1 is a chromophoric group selected from among the group consisting of para-aminobenzalmalonate, aminobenzimidazole, benzimidazole, aminobenzoate, aminosalicylate, anthranilate, aminobenzylidenecamphor, aminobenzotriazole, aminobenzoxazole, para-aminophenylbenzoxazole substituents, a linear or branched C 1 -C 20 aminoalkyl radical, or a C 6 -C 20 aryl radical which can be unsubstituted or substituted by alkyl, hydroxyl and/or alkoxy radicals.
