Abstract
Disclosed are aqueous, single-package or two-package coating compositions having pH above 7.0 that contain as the binder a polyurea which is the product of a polyisocyanate and an anionic amino polymer synthesized in water from olefinically unsaturated monomers including primary or secondary amine containing monomers, the monomers being substantially free of acid groups. The polymerization of the amino polymer is carried out in the presence of an azo initiator dispersed in water by neutralization of acid groups present on the initiator.
