Abstract
Abstract Novel aqueous adhesive and coating compositions composed of (1) an aqueous emulsion (latex) or dispersion of a polymer or interpolymer of one or more vinyl monomers such as an emulsion of a copolymer of vinyl acetate and butyl acrylate and (2) an aqueous emulsion or dispersion of a polyisocyanate which has at least partially reacted with an alcohol having the formula ROH wherein R is a hydrocarbon radical having at least one carbon atom and wherein the dispersion or emulsion (2) is stabilized with a combined surfactant and alcohol having the formula R' wherein R' is a hydrocarbon radical having at least one carbon atom are described.
