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, print-resistance and film-formation to yield coherent films at room temperature or below, of a non-volatile, reactive monomer comprising a (meth)acrylic acid ester of a monohydroxy diolether of dicyclopentenyl alcohol to serve as an air-curing coalescent. |
