Abstract
An aqueous coating composition which comprises at least one aqueous resin selected from polyester, alkyd, acrylic, acryl modified--polyester and acryl modified--alkyd resins, and at least one water--insoluble resinous particles obtained by the polymerization or copolymerization of .alpha., .beta.--ethylenically unsaturated monomers, which is characterized by that said resinous particles are composed of mixture of (A) group of particles having a mean grain diameter of 0.3.about.6.mu. and (B) group of particles having a mean grain diameter of 0.01.about.0.1.mu., in weight ratio of (A)/(B)=99.9/0.1.about.40/60 and that the solid weight ratio of said aqueous resin to water insoluble resinous particles is 99/1.about.15/85. The coating composition is well balanced in application characteristics and in film performance as gloss and surface smoothness and hence is quite useful as a top coat.
