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, 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.
The designation (meth)acrylic acid is intended to refer to either acrylic acid or methacrylic acid and also generically to both. Similarly, (meth)acrylate, if and when used in the specification and claims herein, is intended to generically refer to an "acrylate" and a "methacrylate".
