Abstract

Abstract The present invention relates to quaternized polyamines having the basic structure of formula I, <IMAGE> I in which each R independently, is (C10-22)alkyl, (C10-22)alkenyl, phenyl(C1-3)alkyl or naphthyl(C1-3)alkyl, each R1, independently, is phenyl(C1-3)alkyl or naphthyl (C1-3)alkyl, z, is 1 to 5, each y1, independently is an integer from 2 to 8, y2, is an integer from 2 to 8, with the proviso that when z=1,y1 NOTEQUAL y2 and when z>1 and the y1's are the same y2 NOTEQUAL y1 and wherein an average of 0.5 to 2.0 nitrogen atoms are quaternized with alkyl radicals containing from 1 to 6 carbon atoms and mixtures of such quaternized polyamines with further quaternized polyamines, such polyamines and mixtures being useful as dye retarders/levelling agents.
