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.
Claims7
A composition of matter comprising a mixture of an aqueous latex emulsion or dispersion of
- (a) a member selected from the group consisting of a homopolymer of a vinyl monomer and an interpolymer of two or more vinyl monomers, and
- (b) a polyisocyanate which has undergone at least partial reaction of some of its isocyanate groups with a monohydroxy alcohol.
A process comprising applying to at least one surface of a material a mixture of an aqueous latex, emulsion or dispersion of
- (a) a member selected from the group consisting of a homopolymer of a vinyl monomer and an interpolymer of two or more vinyl monomers, and
- (b) a polyisocyanate which has undergone at least partial reaction of some of its isocyanate groups with a monohydroxy alcohol.
A process which comprises (1) treating at least one surface of a material with a mixture of an aqueous latex, emulsion or dispersion of (a) a member selected from the group consisting of a homopolymer of a vinyl monomer and an interpolymer of two or more vinyl monomers, and (b) a polyisocyanate which has undergone at least partial reaction of some of its isocyanate groups with a monohydroxy alcohol, and (2) adhering another surface of the same or a different material to said treated surface.
