摘要：
A homogeneous composition for forming on firing a film of precious metal, which is one or more of platinum, palladium, gold and silver, on a substrate, for instance to decorate table ware, comprises polymeric resin and a solution, in water and a co-solvent, of thiolate of the precious metal, the composition containing 3-22% by weight of the precious metal as the thiolate, and the co-solvent, resin and thiolate being such that as the composition on a substrate dries and is progressively heated in firing, the water evaporates off to leave a homogeneous composition of the resin and thiolate in the co-solvent, then the co-solvent evaporates off to leave a homogeneous composition of the thiolate in the resin, and then the thiolate decomposes to the precious metal while the resin volatilise.
