Abstract
Autocrosslinking aqueous dispersions characterized by an MFT of from 0.degree. to about 50.degree. C. include at least one carbonyl-containing soft latex polymer having an MFT of below about 20.degree. C., at least one hard latex polymer having an MFT of above about 25.degree. C., and at least one polyfunctional carboxylic hydrazide. The aqueous polymer dispersions are used as binders for non-blocking, scratch-resistant and chemical-resistant coatings and as binders for clear coat and pigmented coating systems.
