Claim:
A washing product comprising a surfactant and a dye transfer inhibitor selected from the group consisting of triazine derivatives of the general formulae I, II, III and combinations thereof: T(NH—Ar(SO 3 Na) a ) b Hal c (I) X(NH-T(NH—Ar(SO 3 Na) a ) e Hal f ) 2 (II) X(NH-T(NH—Ar(SO 3 Na) d —NH-T(NH—Ar(SO 3 Na) a )Hal)Hal) 2 (III) wherein the product comprises at least one triazine derivative of the general formulae II, wherein T represents a 1,3,5-triazinyl residue; each Ar independently represents a naphthalene or benzene moiety; X represents a divalent hydrocarbyl moiety selected from the group consisting of linear or branched C 1-20 hydrocarbon groups which optionally may include one or more —N(H)— carbon chain interruptions, stilbene groups and biphenyl groups which optionally may be mono- or poly-SO 3 Na-substituted; each Hal independently represents a halogen selected from the group consisting of chlorine, bromine, and iodine; each of a and d independently represents 1, 2 or 3; b and c each represent 1 or 2 such that b+c=3; e represents 1 or 2 and f represents 0 or 1 such that e+f=2; and wherein the triazinyl residue substituents are located at the 2, 4 and 6 positions of the 1,3,5-triazinyl residue; and wherein the triazine derivative of the general formula II is prepared by a process comprising reacting two equivalents of a triazine derivative of the general formula I with one equivalent of an amino compound selected from the group consisting of C 1-20 diaminoalkanes, diaminostilbenes, diaminobiphenyls, and mixtures thereof; wherein the amino compound comprises a diaminoalkane selected from the group consisting of oligo-ethyleneimines and poly-ethyleneimines of the general formula NH 2 —CH 2 CH 2 —(NH—CH 2 CH 2 —) n NH 2 , wherein n represents a number of 1 to 9.
