Abstract
A novel polymer mordant which is represented by the general formula (I): ##STR1## wherein A represents a monomer unit produced by copolymerization of copolymerizable monomers having at least two ethylenically unsaturated groups; B represents a monomer unit produced by copolymerization of copolymerizable ethylenically unsaturated monomers; R.sup.1 represents a hydrogen atom or a C.sub.1-6 alkyl group; L represents --CH.sub.2 O--, --CH.sub.2 N(R.sup.6)--, ##STR2## in which R.sup.6 and R.sup.7 each represents a hydrogen atom or an alkyl group; M represents a C.sub.1-12 divalent group; R.sup.2, R.sup.3 and R.sup.4, which may be the same or different, each represents a C.sub.1-20 alkyl group or a C.sub.7-20 aralkyl group and at least two of R.sup.2, R.sup.3 and R.sup.4 may be connected to each other to form a cyclic structure together with the nitrogen atom; R.sup.5 represents a C.sub.1-20 alkyl group, a substituted C.sub.1-20 alkyl group, a C.sub.1-20 alkoxy group, a C.sub.1-20 acylamino group, or a halogen atom; X.crclbar. represents an anion; x represents 10 to 80 mol %; y represents 0 to 90 mol %; z represents 10 to 100 mol %; and n represents an integer of 0, 1, or 2.
