An aqueous coating composition comprising a resin in a water-soluble or water-dispersible form as a film-forming component, said resin being a copolymer of (A) a fatty acid-modified acrylic monomer comprising the reaction product of an unsaturated fatty acid having at least two non-conjugated double bonds with a hydroxyl-containing acrylic or methacrylic ester, (B) an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and (C) an unsaturated monomer having a Q value, determined by the Q-e theory, of at least 0.1.

An aqueous coating composition comprising as film-forming components

An aqueous resin composition cross-linkable by oxidation and prepared by dissolving a radical-polymerizable poly-functional monomer in an aqueous solution of at least one of water-soluble resins having a drying oil fatty acid group or semi-drying oil fatty acid group and neutralized maleates of synthetic petroleum resins having an unsaturated bond of the vinyl or non-vinyl type, and polymerizing the monomer in the solution.

Aqueous resin composition cross-linkable by oxidation

An emulsion composition prepared by the emulsion polymerization of a polymerizable vinyl monomer in the presence of an emulsifier characterized in that the emulsifier is a neutralized copolymer of (A) a monomer prepared by being allowed at least one glycidyl ester of arcylic acid and methacrylic acid to react with at least one fatty acid of drying oil fatty acid and semi-drying oil fatty acid, (B) .alpha.,.beta.-ethylenically unsaturated acid and (C) an unsaturated monomer containing substantially no carboxyl group and having a Q value of at least 0.1 as determined by Q-e theory.

Emulsion composition

An emulsion composition prepared by the emulsion polymerization of a polymerizable vinyl monomer in the presence of an emulsifier characterized in that the emusifier is a neutralized maleate, partial maleate, fumarate or partial fumarate of an addition polymerization polymer having as a side chain a drying oil fatty acid residue and/or semi-drying oil fatty acid residue linked to the main chain of the polymer by an ester bond.

Emulsion compositions
