ABSTRACT:
A coating composition capable of producing a coating film having excellent water-proof property, solvent-resistant property, chemical-resistant property, thermal stability and hardness, which comprises water, a water-soluble solvent and a water-soluble, thermosetting resin as essential, film-forming component, which resin is prepared by (A) adding an amine to 100 parts by weight of a copolymer obtained by the copolymerization of (1) 5 to 30 parts by weight of an .alpha.,.beta.-ethylenically unsaturated acid component, (2) 5 to 50 parts by weight of an addition product component containing hydroxyl group and a tertiary aliphatic group having 4 to 26 carbon atoms, (3) 40 to 90 parts by weight of a hydroxy-free, polymerizable, unsaturated monomer component and (4) up to 20 parts by weight of a polymerizable unsaturated monomer component having a hydroxyl group in its molecule, the amount of said amine being 0.5 to 2.0 equivalent with respect to the carboxyl group in said copolymer, to form a water-soluble salt; and (B) adding to said salt 4 to 50 parts by weight of a water-soluble amino resin. A process for preparing the coating composition and an article coated with the composition are provided.
