An agent (e.g. a primer) for treating the surfaces of metals, in which a polymerizable monomer containing a thiophosphoric acid dichloride group is dissolved in an organic solvent in an amount of 0.001 to 10% by weight. By applying this agent to the surfaces of noble metals, much more durable and increased bond strength is obtained. The monomer used is of formula (I) or (II): <IMAGE> |
