Abstract
The present invention is a composition comprising a) an aqueous dispersion of TiOparticles encapsulated with an encapsulating acrylic or styrene-acrylic polymer comprising from structural units of diacetone acrylamide; and b) adipic acid dihydrazide. The composition is useful in coatings applications and shows a surprising improvement in gloss over compositions that do not include diacetone acrylamide functionalized encapsulating polymer and adipic acid dihydrazide.
