ABSTRACT:
A rubber composition containing reinforcing pigment some of which is preferably silica pigment, sulfur, a vulcanization accelerator, litharge, and a cobalt salt, when coated on brass plated steel cords and vulcanized, adheres tenaciously and permanently to the cords, without the erratic adhesion previously obtained or loss of adhesion in humid atmospheres. A further improvement in adhesion is obtained by including a resorcinol resin in the composition.
