Claim:
A water-soluble substituted s-triazine compound having the formula (1): in which two of the radicals R 1 , R 1 ′ and R 1 ″ are of the formulae: and the other radical, which may be identical or different, is either: (i) a chromophore group of one of the following formulae: in which: R 2 is a linear or branched C 1 -C 8 alkyl radical n is 0, 1 or 2; the radicals A, which may be identical or different, are each an alkali metal cation, an ammonium group, a C 1 -C 20 mono-, di- or trialkylammonium radical, a C 2 -C 20 mono-, di- or trialkanolammonium radical, or a C 5 -C 8 quaternary nitrogen-containing heterocyclic ring member; R 3 is a linear or branched C 1 -C 20 alkyl radical, or a linear or branched C 2 -C 20 alkenyl radical, said radicals optionally containing one or more oxygen atoms, silicon atoms or trisiloxane groups; R 4 is a linear or branched C 1 -C 20 alkyl radical, a linear or branched C 2 -C 20 alkenyl radical, or a linear or branched C 1 -C 20 alkoxy radical, said radicals optionally containing one or more oxygen atoms, silicon atoms or trisiloxane groups; R 5 is hydrogen or OH, and X is O, S or NR 6 , wherein R 6 is H or a linear or branched C 1 -C 4 alkyl radical; or (ii) an OH; a linear or branched C 1 -C 20 alkoxy radical, or a linear or branched C 1 -C 20 mono- or dialkylamino radical, said radicals optionally containing one or more oxygen atoms, silicon atoms or trisiloxane groups.
