    Abstract: The fastness properties of basic dyeings on cellulosic substrates are improved by treating the substrate with a fixing agent comprising a precondensate or mixture of(A) the reaction product of an amine with cyanamide, dicyandiamide, guanidine or biguanidine, or,(B) a quaternary polyalkylene polyamine with(C) formaldehyde and/or,(D) an N-methylol compound optionally together with(E) a catalyst, e.g. MgCl.sub.2.The fixing agents are normally applied as an aftertreatment, with a subsequent heat-curing step.

    Abstract: A process for improving the fastness properties of a sulphur dyestuff on a substrate comprising hydroxy group-containing fibres by applying to the dyed or printed substrate the reaction product (R) of(A) the product of reacting a mono- or polyfunctional primary or secondary amine with cyanamide, dicyanodiamide, guanidine or bi-guanidine; said product containing reactive hydrogen atoms bound to nitrogen, and(B) an N-methylol derivative of a urea, melamine, guanamine, triazinone, urone, carbamate or acid amidein the presence of (C) a catalyst for the crosslinking of N-methylol compounds of the type (B) above, and subsequently carrying out a heat-curing step.These compounds are useful for the aftertreatment of textile material.
