A reinforcing cord which strongly adheres to a mixednrubber comprising a hydrogenated acrylonitrile-butadienenrubber having excellent flex resistance and heat resistance andna hydrogenated acrylonitrile-butadiene rubber havingndispersed therein zinc methacrylatte, and a treating materialnfor forming a coating layer on the cord. n The reinforcing cord comprises a fiber for reinforcingna rubber, a first coating layer formed on the surface of thenfiber, obtained by coating a treating material comprising anresorcin/formalin condensate and a rubber latex on the surfacenthereof, and a second coating layer formed on the first coatingnlayer, obtained by coating another treating material comprisingna rubber compound, a vulcanizing agent and one member selectednfrom the group consisting of a silane coupling agent, anmaleimide type vulcanization assistant and a dimethacrylatentype vulcanization assistant. |
