Curable coating compositions containing polystyrene microparticles

Abstract

A curable top coating composition essentially including (A) a hydroxyl-containing vinyl type resin containing 45 to 55% by weight of styrene monomer as a copolymerized unit of the resin, (B) at least one member selected from among amino resins and (blocked) polyisocyanate compounds, and (C) a microparticulate polymer having an average particle diameter within the range of 0.01 to 1 .mu.m and containing 40 to 60% by weight of styrene monomer as a copolymerized component of each particle, wherein the cured film from the coating composition contains the styrene-derived benzene ring in a proportion of 13 to 40% by weight of the total resin solids; a coating method using the above coating composition, and a coated article obtainable by using the above coating composition.
