Abstract

Dyeings on cellulose with direct or reactive dyestuffs are given improved wet fastness properties by aftertreatment with a reaction product or mixture of a polybasic amino compound (A) with an N-methylol compound (B) or with formaldehyde or a formaldehyde donor and optionally a crosslinking catalyst (C). Particularly good results are obtained when the dyestuff and the polybasic amino compound (A) are such that when mixed together in aqueous solution they give a precipitate which, after washing and drying does not redissolve in aqueous alkali at pH>/=12 at room temperature.
