ABSTRACT:
In the inventive method, shaped articles of a plasticized polyvinyl chloride resin are subjected to the surface treatment by with low temperature plasma so that the undesirable phenomenon of bleeding of the plasticizer on the surface can be effectively prevented when the plasticizer for plasticizing the resin is a compound having at least one aromatic nucleus in a molecule or a combination of two or more of plasticizers including 10% by weight or more of a plasticizer which is a compound having at least one aromatic nucleus in a molecule.
