Abstract
A coating composition comprising PA1 (A) a film-forming binder resin, PA1 (B) a volatile organic liquid diluent dissolving the film-forming binder resin (A) and PA1 (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, and PA1 the fine polymer particles (C) being fine particles of gelled polymer obtained by emulsion polymerization of PA1 (a) a polymerizable monomer having at least two radical-polymerizable unsaturated groups in the molecule, and PA1 (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.
