ABSTRACT:
The invention discloses thermosetting water-based paint comprising water-dispersible acrylic polymer particles which are obtained through multi-stage emulsion polymerization of radical polymerizable unsaturated monomers using a specific reactive emulsifying agent, said monomers comprising amido-containing radical polymerizable unsaturated monomer having at least 2 radical polymerizable unsaturated groups per molecule, methacrylic acid and hydroxyl-containing radical polymerizable unsaturated monomer; and coating film-forming methods which use the thermosetting water-based paint.
