Abstract
A curable aqueous coating composition in which dicyandiamide or a salt of guanidine is mixed and dissolved in an aqueous solution of a salt of a copolymer of an acrylic monomer mixture containing an unsaturated carboxylic acid monomer and a hydroxyalkyl acrylate or methacrylate monomer.
Claims6
A curable aqueous coating composition comprising dicyandiamide and/or a water soluble salt of guanidine dissolved in an aqueous solution of a water soluble salt of a copolymer comprising about 5 to about 30 wt% of one or more unsaturated carboxylic acid monomers, about 10 to about 50 wt% of one or more hydroxyalkyl (alkyl carbons:
- 2-8) acrylate or methacrylate monomers and about 20 to about 85 wt% of one or more (C.sub.1 -C.sub.18) alkyl acrylate monomers, where the amount of the dicyandiamide and/or the water soluble salt of guanidine is about 0.1 to about 1.0 mol equivalent per 1 mol of hydroxyl group containing monomers in the copolymer.
