An aqueous coating composition comprising (A) an aqueous medium, (B) at least one water soluble or dilutable resin which has a water tolerance of 4 or more and whose 1% by weight aqueous solution shows a surface tension of 51 dyne/cm or less, and (C) fine particles of resinous solution of water insoluble resin in a hydrophobic solvent, the particles being uniformly dispersed in the combination of said aqueous medium (A) and the water soluble or dilutable resin (B) and having a mean diameter of 1 mu or less, which is characterized in that the absolute value of difference in solubility parameter (¦ DELTA Sp¦) between said resinous solution and said water soluble or dilutable resin is within a range of ¦ DELTA Sp¦<2. The present coating composition is excellent in storage stability and application characteristics, resulting a coating with excellent gloss and surface smoothness. |
