Abstract: Surface-decorating method for articles made of a plastic material, comprising the steps of applying a layer of lacquer or resin on said plastic material, in which said lacquer or resin becomes receptive at a temperature (Tf) that is lower than the softening point of the plastic material and applying a support comprising the decoration onto the plastic material. The assembly constituted by the support and the plastic material is subsequently heated up in an ambient at pressure is lower than or equal to the atmospheric one, until a temperature is reached, at which the lacquer or resin becomes receptive.

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.
