ABSTRACT OF THE DISCLOSURE Lightweight coated paper products with improved properties are obtained by use of coating compositions employing as the binder component certain novel polymeric dispersions which comprise (A) a major proportion on a dry basis of an alkali-insoluble polymer and (B) a minor proportion (e.g., from 0.5 to 25 weight percent on a dry basis based upon the alkali-insoluble polymer) of certain alkali-soluble polymers. Exemplary of the alkali-insol- uble polymers employed are carboxylated and noncarboxy- lated addition polymerized synthetic polymers having a glass transition temperature of about 50°C or less. Exemplary of the alkali-soluble polymers are synthetic addition polymers comprising in polymerized form (1) about 40 to 90 weight percent of a vinyl ester of a carboxylic acid (e.g., vinyl acetate, vinyl propionate, etc.); (2) about 5 to 55 percent of the nitrile, C2-C4 hydroxyalkyl ester, or C1-C8 alkyl ester of a monoethyl- enically unsaturated carboxylic acid; and (3) about 5 to 15 percent of a monoethylenically unsaturated carboxylic acid. 27,846-F
