Aqueous coating composition

Aqueous paint composition, comprising

• 1) a latex which is a film-forming latex polymer having anionic property, where the solubility of the monomers to form the polymer, excluding the monomers having anionic property, is 0.01-1.50 g per 100 g of water, and
• (2) water-soluble or water-dispersible polyvalent metal.

Aqueous paint composition, comprising a latex which is a film-forming latex polymer having anionic property, modified by water-soluble or water-dispersible polyvalent metal, where the solubility of the monomers to form the polymer, excluding the monomers having anionic property, is 0.01-1.50 g per 100 g of water reacted with a water-soluble or water-dispersible polyvalent metal.

• (2) water-soluble or water-dispersible polymer, formed from a monomer mixture containing at least 20 weight % of amine functional group-containing monomer, and
• (3) from one to four equivalents of a volatile base selected from the group consisting of ammonia, morpholine, alkylamines, 2-dimethylaminoethanol, N-methyl morpholine, ethylenediamine and their mixtures, based on a titrated amount of latex acid and polyamine.
