Fine particles of high heat resistant polymer prepared by copolymerizing at least one epoxy ester (C) having two or more unsaturated double bonds in one molecules and at least one reactive monomer (D) having at least one vinyl group in one molecule, the at least one epoxy ester (C) being obtained by adding at least one unsaturated monobasic acid (B) to at least one epoxide (A-1) having at least one glycidyl group in one molecule and a monocyclic hydrocarbon and/or to at least one epoxide (A-2) having at least one cycloaliphatic epoxy group in one molecule. The fine polymer particles have excellent heat resistance and solvent resistance, and an aqueous or alcoholic dispersion of such fine polymer particles is produced therefrom. Also, the epoxy ester used as an intermediate material provides a uniform emulsion for preparing the fine polymer particles.
