Abstract
Abstract The invention provides nickel and cobalt chelate complexes of a nickel or cobalt salt and a succinosuccinate of the formula I <IMAGE> (I) , wherein R represents a substituted or unsubstituted hydrocarbon radical of aliphatic or aromatic character. These complexes are excellent adhesion promoters for vulcanized rubber on metal surfaces.
