Abstract:
A polyurethane hybrid dispersion comprising:(a) 10 to 95 weight percent of a carboxylated polyurethane dispersion with at least 0.6 milliequivalents of carboxyl per gram of polyurethane, which is the reaction product comprising(I) at least one diisocyanate;(II) at least one polyester diol; and(III) at least one carboxylated diol; and(b) 5 to 90 weight percent of a functionalized polymer which is the emulsion polymerization product comprising at least one ethylenically unsaturated monomer and from 0.1 to 5 pphm of at least one ureido functional comonomer, wherein the functionalized polymer is prepared in the presence of the carboxylated polyurethane dispersion, and wherein the weight percents of the carboxylated polyurethane dispersion (a) and functionalized polymer (b) are based on the total solids of the polyurethane hybrid dispersion.
