Abstract
A gloss emulsion paint having improved gloss and flow properties is achieved by incorporating in the latex at least two gloss improving film forming copolymers of an unsaturated monocarboxylic acid with an unsaturated monocarboxylic acid ester, one of the copolymers having an average molecular weight of from 10,000 to 20,000 and containing 5 to 20 mole percent of the acid units and the other having an average molecular weight of 50,000 to 150,000 and containing from 5 to 40 mole percent of the acid units.
