Abstract
It is an object of the present invention to provide a friction transmission belt which is superior in adhesive properties such as dynamic adhesion and heat resistant adhesion on repeated flexing of a friction transmission belt or on running under heating conditions around an engine, and is also superior in desired performance such as heat resistance, abrasion resistance and an abnormal noise-preventing property. The present invention pertains to a friction transmission belt formed by laminating an adhesive rubber layer in which core cords are embedded along the longitudinal direction of the belt and a compressed rubber layer, wherein the above-mentioned adhesive rubber layer is formed by crosslinking an ethylene-α-olefin elastomer compound with organic peroxide, the above-mentioned compressed rubber layer is formed by crosslinking an ethylene-α-olefin elastomer compound, and the above-mentioned core cord is subjected to an adhesive treatment by a resorcin-formalin-latex adhesive composition containing a 2,3-dichlorobutadiene-containing polymer latex.
