    • 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.
    • 包含分散在水相连续相中的交联聚合物微粒的胶乳乳液。 微粒由交联单体,具有亲水性官能团的单体和一种或多种其它单体的单体混合物制备。 还公开了一种热固性组合物,其包括具有反应性官能团的第一反应物; 具有至少两个与第一反应物的官能团反应的官能团的固化剂; 和分散在水性连续相中的交联聚合物微粒的胶乳乳液。 热固性组合物可用于涂覆基材。 涂层可以是多层复合涂层,其包括由含有热固性组合物的着色成膜底涂层组合物沉积的底涂层; 以及从基本上不含颜料的面漆组合物沉积在基底涂层的一部分上的基本上无颜料的顶涂层。
