Water-borne paints having an ASTM 60&deg; gloss value of at least 10 are formulated with a latex of a copolymer of vinyl acetate and ethylene or alkyl acrylate having a dry glass transition temperature (T ) below 20&deg; C. and a latex of a polymer of vinyl acetate having a dry T above room temperature but a T when wet below 23&deg; C. so that it is film-forming from the latex at room temperature. These paints are suitable for service as satin, semi-gloss or high gloss coatings but preferably are used as semi-gloss paints. The addition of the higher T polymer of vinyl acetate to the lower T copolymer provides a paint free with low to no volatile organic content but exhibiting improved blocking resistance without significant reduction in gloss.
