ABSTRACT:
A coating material having excellent adhesion to the surfaces of substrates including metals and excellent flexibility, durability, chemical-resistance and rust-preventive property which comprises water, a water-soluble organic solvent and a water-soluble, thermosetting resin as substantial film-forming component, said resin being obtained by (A) adding an amine to 100 parts by weight of a copolymer consisting of (1) 50 to 80.5 parts by weight of at least one polymerizable, unsaturated monomer free from hydroxyl group, (2) a total of 19.5 to 50 parts by weight of an .alpha.,.beta.-ethylenically unsaturated acid and an epoxy resin having at least two epoxy groups in the molecule, the proportion of said epoxy resin being 0.01 to 0.5 equivalent with respect to the carboxyl group contained in said .alpha.,.beta.-ethylenically unsaturated acid, said .alpha.,.beta.-ethylenically unsaturated acid having been reacted with 10 % or more of the epoxy groups of said epoxy resin, and (3) 0 to 30 parts by weight of at least one polymerizable, unsaturated monomer having a hydroxyl group in the molecule, the total amount of the (1), (2) and (3) components being 100 parts by weight, the amount of said amine being 0.5 to 2.0 equivalent with respect to the carboxyl group in the copolymer, thereby converting said copolymer into a water-soluble salt; and (B) adding, to said water-soluble salt, 4 to 50 parts by weight of a water-soluble amino resin.
