Patent number: 5243047Abstract: A compound contains a ligand group and at least one group of the general formula --XR.sub.n where X is a linking group which contains at least one hetero-atom, R is a saturated hydrocarbyl group containing at least six carbon atoms or is an unsaturated hydrocarbyl group containing at least three carbon atoms. The ligand group can be a polyhydroxyhydrocarbyl, a triazole, an imidazole, an indazole, a thiazole, an oxazole, a carbamate, an xanthate or a phthalazine. The compounds can be used to improve bonding between a metal and a coating material in contact with the metal surface. The metal may be a tire cord and the coating material rubber or a rubber composition.Type: GrantFiled: November 16, 1990Date of Patent: September 7, 1993Assignee: Imperial Chemical Industries PLCInventor: John R. Lawson
