Ambient or low-temperature curable solutions or aqueous dispersions of (1) a polymer containing units polymerized from a monomer mixture of (a) from about 0.25% to about 30% by weight of a polymerizable aldehyde, and (b) at least one copolymerizable mono-ethylenically unsaturated monomer, with (2) a curing agent selected from the group of dicarboxylic acid bis-hydrazides, dicarboxylic acid bis-hydrazones, and acrylic oligomers and low molecular weight acrylic solution polymers containing a plurality of pendant hydrazide or hydrazone groups. The solutions or dispersions are useful as general industrial coatings, maintenance coatings, furniture and appliance coatings, heavy transportation coatings, automobile refinishes and plastics coatings. |
