Abstract
Abstract The fastness of direct dyes on cellulose substrates is improved by after-treatment with the reaction product of a quaternary polyalkylene polyamine with an N-methylol resin precursor, and heat curing in the presence of a catalyst. The unfixed portion of reactive dyes substantive to cellulose may also be given improved wet and light fastness by this treatment.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
133 words
A process for improving the fastness properties of a direct or reactive dyestuff on a substrate comprising cellulose fibers, which process comprises applying to a substrate dyed or printed with such a dyestuff (1) a water-soluble product of reacting in aqueous solution either (A) a quaternary polyalkylene polyamine having at least one --NH--, --NH 2 or --OH group in each recurring unit and (B) an N-methylol derivative of a urea, melamine, guanamine, triazine, urone, carbamate or acid amide, or (A) and (B), as defined above, and (A') the product of reacting a mono- or polyfunctional primary or secondary amine with cyanamide, dicyanodiamide, guanidine or biguanidine, said component (A') containing reactive hydrogen atoms bound to nitrogen, and (2) a catalyst (C) for crosslinking component (B), and subjecting the thus-treated substrate to a heat-curing step.
Claim 2
Dependent Claim
133 words
A process for improving the fastness properties of a direct or reactive dyestuff on a substrate comprising cellulose fibers, which process comprises applying to a substrate dyed or printed with such a dyestuff (1) a water-soluble product of reacting in aqueous solution either (A) a quaternary polyalkylene polyamine having at least one --NH--, --NH 2 or --OH group in each recurring unit and (B) an N-methylol derivative of a urea, melamine, guanamine, triazine, urone, carbamate or acid amide, or (A) and (B), as defined above, and (A') the product of reacting a mono- or polyfunctional primary or secondary amine with cyanamide, dicyanodiamide, guanidine or biguanidine, said component (A') containing reactive hydrogen atoms bound to nitrogen, and (2) a catalyst (C) for crosslinking component (B), and subjecting the thus-treated substrate to a heat-curing step.
Claim 3
Dependent Claim
17 words
A process according to claim 1 wherein, in component (A), each recurring unit contains an --OH group.
Claim 4
Dependent Claim
