An aqueous dispersion coating composition comprising at least one kind of resin, wherein any one of said resin or resins has at least one functional group selected from an active hydrogen-containing group, a substituted acylamide group and a water dispersible or water-soluble group, and wherein the resin composition as a whole contains each of the above described kinds of functional groups.

Aqueous dispersion coating composition

Resin dispersion type aqueous coating composition comprising

A water-borne coating composition, having excellent storage stability and coating appearance, containing a specific graft polymer.

Water-borne coating composition

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 (.vertline..DELTA.Sp.vertline.) between said resinous solution and said water soluble or dilutable resin is within a range of .vertline..DELTA.Sp.vertline.&lt;2. The present coating composition is excellent in storage stability and application characteristics, resulting a coating with excellent gloss and surface smoothness.
