-15- ABSTRACT OF THE DISCLOSURE Rubber compositions and articles such as tires having improved metal adhesion and metal adhesion retention to brass and brass plated metallic reinforcement. The improvement comprises admixing from about 0.2 to about 600 parts per hundred rubber (phr) of a compound selected from the group consisting of 3-amino-2-carboxy-4-chlorobenzo- phenone, 3-hydroxy-2-methyldiphenylamine and 5-amino-2- methyl-N-phenylbenzensulfonamide and mixtures thereof with a vulcanizable rubber composition prior to embedding the metallic reinforcement therein and curing. A method for improving the metal adhesion and metal adhesion retention between a vulcanizable rubber and brass or brass-plated metallic reinforcement includes the step of dispersing from about 0.2 to about 6.0 phr of a compound selected from the group consisting of 3-amino-2-carboxy-4-chlorobenzophenone, 3-hydroxy-2-methyldiphenylamine and 5-amino-2-methyl-N- phenylbenzenesulfonamide and mixtures thereof in a vulcanizable rubber composition prior to curing.
