-23- ABSTRACT OF THE DISCLOSURE Rubber compositions and metal-reinforced rubber ply members have improved metal adhesion and metal adhesion retention to brass and brass-plated metallic reinforcement. The improvement comprises admixing from about 0.5 to about 12.5 parts per hundred rubber (phr) of an organic salt of nickel and at least about 3.0 phr of a thermoplastic resin derived from crude wood rosin containing carboxylic acid groups or carboxylic acid ester groups with a vulcanizable rubber composition prior to embedding the metallic rein- forcement therein and curing. A method for improving the metal adhesion and metal adhesion retention between a vul- canizable rubber and brass or brass-plated metallic rein- forcement includes the steps of dispersing from about 0.5 to about 12.5 phr of an organic salt of nickel in a vulcanizable rubber composition and dispersing at least about 3.0 phr of the aforementioned thermoplastic resin in the same rubber composition prior to curing.
