ABSTRACT:
A process of producing a nonaqueous resin dispersion, particularly useful for a liquid developer in electrostatic photographic, which comprises subjecting to photopolymerization a system containing at least a monomer (A) having one polymerizable double bond, which is soluble in a nonaqueous solvent but becomes insoluble upon polymerization thereof, and at least a dispersion stabilizing resin (P) which is a polymer having a weight average molecular weight of from 1.times.10.sup.4 to 1.times.10.sup.6 and containing a specific repeating unit represented by formula (I) in an amount of at least 50% by weight based on the weight of the polymer and has a specific functional group represented by formula (II) bonded to the side chain of the polymer and/or only one terminal of the main chain of the polymer, the photopolymerization reaction being carried out in the nonaqueous solvent by irradiating the system with ultraviolet rays having a wavelength of not longer than 400 n.m.: ##STR1##
