Abstract
A dispersion of fine particles of a gelled polymer obtainable by copolymerizing and crosslinking a vinyl monomer mixture containing at least 0.5% by weight each of at least two vinyl monomers in the presence of a macromonomer A, which has a molecular chain of poly(12-hydroxystearic acid) and has at least about one polymerizable unsaturated double bond per molecule in average, and a macromonomer B, which is a copolymer of an ethylenic unsaturated monomer and has a solubility parameter value of from 7.5 to 9.2 and about 1.0 to about 1.5 in average of polymerizable unsaturated double bonds, in an organic solvent which is capable of dissolving the macromonomers A and B but is substantially incapable of dissolving a polymer from said vinyl monomer mixture; and a curable resin composition comprising a dispersion of fine particles of the above-described gelled polymer, a base resin which is non-compatible with the macromonomer A but is compatible with the macromonomer B and which forms a continuous phase, and at least one crosslinking agent selected from the group consisting of an amino resin and a polyisocyanate compound.
