Abstract
Abstract The present invention is concerned with film-forming polymer dispersions, especially in aqueous systems, such as aqueous solutions of polymers of monoethylenically unsaturated monomers as well as latices or dispersions in an aqueous medium of water-insoluble particles of polymers, such as those obtained by emulsion polymerization. It involves the addition to such aqueous polymer systems in order to improve hardness, blocking-resistance and film-formation at room temperature or below, of a non-volatile, reactive monomer comprising dicyclopentenyl acrylacte or methacrylate to serve as an air-curing coalescent.
