A method an composition for the bonding fibres to rubbers. The method comprising the steps of the fibres with a primer, treating the fibres with a resorcinol/formalin/latex preparation and curing the rubber in intimate contact with the treated fibres, wherein the primer comprises a ring-opened, maleinised polybotadiene and a phenolic derivative comprising electron-withdrawing groups. The composition can be the primer alone or in combination with the primer alone or in combination with the resorcinol/formalin/latex preparation.
