Abstract
Abstract Quaternary N-(2,3-epoxyalkyl)-ammonium compounds of the formula ##STR1## IN WHICH Y represents a sulphur atom, a CH 2 group, a simple C-C bond or especially an oxygen atom, R 1 represents a C 1 -C 4 -alkyl group, a C 2 -C 4 -alkyl group substituted by an OH group or preferably the methyl group, R 2 represents hydrogen or methyl, X n ( - ) represents an anion and n represents 1, 2 or 3 Are used as fixing agents for substantive dyestuffs on cellulose fibre materials.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
In a process for dyeing cellulose fiber materials with substantive dyestuffs, the improvement comprising employing a quaternary N-(2,3-epoxyalkyl)-ammonium compound of the formula ##STR5## in which Y is an oxygen atom or sulphur atom, a --CH 2 -- group or a direct bond, R 1 is a C 1 -C 4 -alkyl group or a C 2 -C 4 -alkyl group unsubstituted or substituted by an OH group, R 2 is hydrogen or methyl, X n ( - ) is an anion, and n is 1, 2 or 3 as a fixing agent for the dyestuffs.
Claim 2
Dependent Claim
95 words
In a process for dyeing cellulose fiber materials with substantive dyestuffs, the improvement comprising employing a quaternary N-(2,3-epoxyalkyl)-ammonium compound of the formula ##STR5## in which Y is an oxygen atom or sulphur atom, a --CH 2 -- group or a direct bond, R 1 is a C 1 -C 4 -alkyl group or a C 2 -C 4 -alkyl group unsubstituted or substituted by an OH group, R 2 is hydrogen or methyl, X n ( - ) is an anion, and n is 1, 2 or 3 as a fixing agent for the dyestuffs.
Claim 3
Dependent Claim
