Abstract
Compositions comprising at least one acrylic, vinyl acetate or epoxide polymer or copolymer as a film-forming ingredient and an ester of benzoic acid wherein the alcohol portion of the ester is alkyl and contains eight carbon atoms exhibit unexpected improvements in film-forming and applied film properties. In preferred compositions this alcohol portion is 2-ethylhexyl. Additionally, the preferred benzoic acid ester frequently interacts synergistically with benzoic acid esters derived from oligomeric ethylene glycols.
