Abstract: A surface modified, U.V. stabilized translucent or opaque polyvinyl chloride resin article and process for making same is described. The article includes a colored pigment, and is characterized by the substantial absence of titanium dioxide therein. The modified surface is substantially free of residual stabilizer and solvent, and its appearance and degree of surface perfection is substantially the same as unmodified side of the article. The process of the invention is characterized by the steps of immersing the polyvinyl chloride article in a suitable liquid media, contacting with a solution of an ultraviolet light stabilizer in a suitable organic solvent, and displacing residual stabilizer and solvent in a nonevaporative environment, that is, without contacting the air.
