Process for dyeing or printing fibrous material using quaternary polymerized ammonium salts as assistants

Claim 1

A process for dyeing or printing organic fibrous material using a dyeing or printing assistant which contains, as quaternary ammonium salt, (a) a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted 1,2-ethylenediamine or 1,3-propylenediamine, in which the substituents are alkyl of 1 to 4 carbon atoms or together with the nitrogen atom form a 5- or 6-membered ring which optionally contains an oxygen atom as second heteroatom, (b) a homopolymer of a 4-vinylpyridine which is unsubstituted or substituted at a ring carbon atom by methyl or ethyl, (c) a copolymer of the above vinylpyridine and styrene, and the reaction product (a), the homopolymer (b) and the copolymer (c) are quaternised with an alkyl or alkenyl halide containing up to 6 carbon atoms alone, or with a halomethylnaphthalene, halomethyldiphenyl, chloroacetamide, chloroacetonitrile, or with a haloacetic acid or an alkali metal salt or alkyl ester of haloacetic acid containing 1 to 12 carbon atoms in the alkyl moiety, or with a benzyl halide which is unsubstituted or substituted by halogen, methyl or ethyl, alone or in admixture with each other or with an alkyl or alkenyl halide containing up to 4 carbon atoms, or (d) a homopolymer of a 2- or 4-vinylbenzyl chloride which is quaternised with a tertiary monoamine containing up to 20 carbon atoms, whilst two substituents of the monoamine are alkyl of 1 to 4 carbon atoms or together with the nitrogen atom form a 5- or 6-membered ring which optionally contains an oxygen atom as second heteroatom, and the third substituent of the monoamine is alkyl, alkenyl or aryl containing up to 18 carbon atoms which is unsubstituted or substituted by alkyl or alkylene.
