Abstract: An aqueous polyurethane dispersion and thermosetting compositions containing them. The aqueous polyurethane dispersion includes an aqueous medium with dispersed polyurethane-acrylate particles, which include the reaction product obtained by polymerizing a pre-emulsion formed from hydrophobic polymerizable ethylenically unsaturated monomers, a crosslinking monomer, and an active hydrogen-containing polyurethane acrylate prepolymer, which is a reaction product obtained by reacting a polyol, a polymerizable, ethylenically unsaturated monomer containing at least one hydroxyl group, a compound that includes an alkyl group having at least one hydroxyl group and optionally a carboxylic acid group, and a polyisocyanate.

Abstract: A latex emulsion that includes crosslinked polymeric microparticles dispersed in an aqueous continuous phase. The microparticles are prepared from a monomer mix of a crosslinking monomer, a monomer having hydrophilic functional groups, and one or more other monomers. Also disclosed is a thermosetting composition that includes a first reactant that has reactive functional groups; a curing agent that has at least two functional groups reactive with the functional groups of the first reactant; and the latex emulsion of crosslinked polymeric microparticles dispersed in an aqueous continuous phase. The thermosetting composition may be used to coat a substrate. The coating may be a multi-layer composite coating that includes a base coat layer deposited from a pigmented film-forming base coat composition containing the thermosetting composition; and a substantially pigment free top coat layer deposited over a portion of the base coat layer from a substantially pigment free top coat composition.
