ABSTRACT:
A method for surface coloring plastic objects after manufacture. The method consists of a first step for impregnating a printed paper substrate, whereon pigments of the family known as disperse inks and/or sublimatic inks are deposited within the printing inks, with an aqueous solution of a solvent which activates the print and is capable of activating the surface of the plastic to be treated. Another step consists in covering the parts of the object to be treated with the paper substrate and in then removing the substrate and drying the parts. The final step consists of introduction into an atmosphere of vapors of a product which is a solvent for the pigments, for a time sufficient to fix the pigments to the surface.
