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.
