PURPOSE:To provide a coating film improved in smoothness, gloss, and water resistance while preventing environmental pollution by formulating specific fine polymer particles into an aq. compsn. CONSTITUTION:0.1-80 pts.wt ethylenically unsatd. monomer having a 2-oxo-1,3- dioxolan-4-yl group of the formula (wherein R , R , and R are each H or 1-4C alkyl) and another copolymerizable ethylenically unsatd. monomer are emulsion or dispersion-copolymerized in an aq. medium to give fine polymer particles, which are reacted with a compd. having a primary and/or a secondary amino group in an equivalent ratio of the amino groups in the compd. The cyclocarbonate groups in the polymer of 0.05-1.0 to give an aq. compsn. of internally cross-linked fine polymer particles, which is incorporated into the objective compsn. as the resin component.
