Abstract
An aqueous polymer emulsion latex is claimed composed of particles comprising a vinyl polymer and a surfactant containing at least one hydrophobic moiety and at least one hydrophilic moiety and also carrying silicon moieties and amido functionalities. Also claimed are coating compositions containing the aqueous polymer emulsion latex, processes for preparing the aqueous polymer emulsion latex wherein ethylenically unsaturated monomers are polymerized in the presence of a surfactant containing a silicon moiety and amido functionality, and substrates carrying a coating composition containing the aqueous polymer emulsion latex.
