US 4,141,868 A · Water-based coating compositions

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".

Dependent claims

A composition adapted to coat and/or impregnate a substrate comprising an aqueous dispersion of a vinyl addition polymer, about 1% to 200% by weight, based on the weight of dispersed polymer, of an ester-ether monomer of formula I herein, and from 0.0005% to 2% by weight, based on the weight of formula I monomer component, of a drier, formula I being as follows:

##STR2## wherein R is H or CH.sub.3, and
R.degree. is an alkylene group having 2 to 12 carbon atoms or an oxaalkylene group having at least 4 to 12 carbon atoms and having at least one oxygen atom joining distinct segments of the alkylene group, each such segment having at least 2 carbon atoms.
