An adhesive composition for bonding metal to natural or synthetic rubber, composed of a latex, an aromatic nitroso compound, and a polymaleimide compound. The adhesive composition may be formed by ballmilling the latex and the polymaleimide compound into a masterbatch of the aromatic nitroso compound. Bonded articles may be formed by applying the adhesive composition to a metal and contacting the metal surface with the rubber to effect bonding.
