ABSTRACT:
A process for dyeing or printing organic fibrous material made e.g. of polyamide, polyester or polyacrylonitrile, and also of cellulose, said process comprising the use of a dyeing or printing assistant which contains a quaternary ammonium salt. The salt is a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted n-alkylenediamine, a homopolymer of a vinylpyridine, or a quaternized copolymer of a vinylpyridine and styrene. The reaction product, the homopolymer, and the copolymer are quaternized with e.g. benzyl chloride. The ammonium salt can also be a homopolymer of a vinylbenzyl chloride which is quaternized with a tertiary monoamine. The fibrous material dyed or printed with e.g. direct or disperse dyes or with cationic dyes has excellent levelness, good penetration of the dye, and good wetfastness properties. It is also possible to obtain multi-shade effects by printing the material patchwise with a reserve paste and then dyeing it.
