Abstract:
The process for producing a cationic emulsion according to claim 1, wherein the polymer A1 contains a polymerizable prepolymer E2 having a polymerizable double bond having both an amino group and an acid group wherein said E2 is obtained byfirst preparing a prepolymer E1 having a weight average molecular weight of 1,000 to 30,000 by copolymerizing an amino group-containing, polymerizable compound with a compound copolymerizable therewith in the presence of a terminal carboxyl group-containing polymerization initiator, and reacting said prepolymer E1 with an epoxy group-containing compound represented by the general formula (I) in a proportion of 0.1 to 1.0 equivalent per equivalent of the amino groups of said amino group-containing, polymerizable compound.
