Good adhesion of rubber to metal is very important in rubber articles containing metal reinforcement. For example, in a steel belted tire good adhesion between the tire rubber and the metal tire cord is of utmost importance. Good metal to rubber adhesion is also of great importance in a variety of other rubber products, including power transmission belts, conveyor belts, and rubber hoses containing metal reinforcements. This invention reveals the use of certain adhesion promoters that are useful in rubber products containing metal reinforcements. More specifically, this invention discloses the use of allyl phosphite esters, allyl phosphate esters, 5-nitro isatoic anhydride, iminodiacetic acids, N-substituted iminodiacetic acids, salts of N-substituted iminodiacetic acids, and salts of iminodiacetic acids as adhesion promoters in composites containing rubber and metal.
