A layer is provided for bonding a conductive plating to a substrate which substrate normally does not provide firm bonding of plating directly thereto. The bonding layer forms a matrix in which are dispersed ultrafine metal particles. The bonding layer is formed in situ on the substrate surface with the metal particles being maintained unaggregated in the matrix as it is formed on the surface. Plating subsequently formed on the outer surface of the bonding layer is effectively firmly bonded to the substrate through the intermediary of the matrix and metal particles distributed therein. The bonding layer includes a fixative formed of an organic compound including a metal and an organic solvent. The bonding layer may further include a film strengthener.

A polymer composite contains colorant molecules dispersed therein. The colorant molecules can be dispersed in the polymer or bound to the polymer molecules. When the polymer is a polyamide, the polyamide is in a noncrystalline state due to the inhibition of crystallization imparted by the size and shape of the colorant molecules because the colorant is separated on a molecular level. A high colorant availability is obtained. A method of producing the polymer composite includes the steps of forming a metastable polymer resin layer, applying a film of colorant to the layer, stabilizing the layer, dissolving the stable layer in a solvent, aspirating the solution to remove impurities and aggregates and then removing the solvent. A polymer composition can be produced by mixing the polymer composite with a polymer.
