Coating composition comprising particles of an emulsion polymerized gelled polymer

A coating composition comprising

• (A) a film-forming binder resin,
• (B) a volatile organic liquid diluent in an amount sufficient for dissolving the film-forming binder resin (A) and
• (C) fine particles of a polymer which does not dissolve in a solution of the binder resin (A) in the diluent (B) but are dispersed stably in said solution the amount of said fine polymer particles (C) being 0.1 to 30 parts by weight per 100 parts by weight of said binder resin (A), and
• the fine polymer particles (C) being fine particles of gelled polymer obtained by emulsion polymerization of
• (a) a polymerization monomer having at least two radical-polymerizable unsaturated groups in the molecule, and
• (b) a radical polymerizable unsaturated monomer other than the monomer (a),
• in the presence of a reactive emulsifier having an allyl group in the molecule.
