Abstract: 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.
