Coloration process

Claim 1

A process for the colouration of cellulose or wool textile materials which comprises applying a dyestuff containing one or more s-triazinyl groups bearing a quaternary nitrogen substituent, or the precursors of such a dyestuff, in the absence of an acid-binding agent and heating the treated textile material to 150° C. or higher to fix the dyestuff to the cellulose or wool, the dyestuff being selected from the group consisting of (a) dyestuffs of the formula: ##STR30## where D is a chromophoric group; A is Cl, Br or F; B is a substituent unreactive to cellulose and ##STR31## is derived from a tertiary amine selected from trimethylamine, triethylene diamine, pyridine, a methyl pyridine or a carboxy pyridine of the formula: ##STR32## where n=0 or 1 and m=1 or 2, and (b) dyestuffs derived from a halotriazinyl dyestuff of the formula: ##STR33## where A, B and D have the meanings given above and Dm is a diamine residue linking the triazine nuclei by its two amino groups, and from a tertiary amine as defined for dyestuff (a).
