ABSTRACT OF THE DISCLOSURE An aqueous binder dispersion for use in the produc- tion of composite bodies by vulcanizing a vulcanizable rubber composition on a substrate which is stable under vulcanization conditions comprising water and at least one emulsifier and a solids content of from 20% to 50% by weight of a solids composition of, (a) per 1000 parts by weight of a polymer selected from the group consisting of polyvinylidene chloride, vinylidene chloride/alkyl acrylate copolymers,butadiene/ acrylonitrile copolymers and mixtures thereof, (b) from 100 to 500 parts by weight of at least one aromatic poly-C-nitroso compound, (c) from 50 to 300 parts by weight of masked polyfunctional isocyanates, (d) from 20 to 100 parts by weight of a water- soluble polymer selected from the group consisting of polyvinyl pyrrolidone and water-soluble copolymers of vinyl pyrrolidone, and (e) from 5 to 500 parts by weight of customary fillers and pigments, adhesion-improving resins based on formaldehyde condensation products, adhesion-improving condensation products based on epichlorohydrin condensation products, emulsifiers and antifoam agents; as well as the method of bonding rubbers to solid sub- strates employing said aqueous binder dispersion. -A-
