Quaternary ammonium halides

Abstract

Abstract The invention provides a process for increasing the affinity for anionic dyes of undyed water-insoluble high molecular weight organic compounds containing groups which can be alkylated, which process comprises reacting the high molecular weight compound with an ammonium salt of the formula: ##EQU1## in which X signifies chlorine or bromine. Y signifies a radical of formula --CH=CH-- or a phenylene radical which is unsubstituted or substituted by up to a total of 2 alkyl groups which may be methyl or ethyl, R 1 , r 2 and R 3 , independently signify hydrocarbon radicals consisting of aromatic and/or saturated aliphatic units, or Two of R 1 , R 2 and R 3 jointly with the N atom form a heterocyclic ring, which is selected from heterocyclic rings containing one nitrogen atom, two nitrogen atoms and one nitrogen atom and one oxygen atom, and the other signifies a hydrocarbon radical as defined above or a further bond when the ring is unsaturated, The total number of carbon atoms in R 1 , R 2 and R 3 not being greater than 20, and the N atom not being bound directly to more than one aromatic radical. The invention also provides novel compounds included within the above formula, but with the proviso that (i) when Y signifies --CH=CH-- or a 1,4-phenyl radical and two of R 1 , R 2 and R 3 signify methyl, the other does not signify phenyl, or (ii) when Y signifies --CH=CH-- then R 1 , R 2 and R 3 do not all signify methyl.
