Abstract: The invention provides a novel method for obtaining a shaped article of a vinyl chloride-based resin which is markedly insusceptible to the undesirable phenomenon of exudation or bleeding of the plasticizer and other additive ingredients contained therein on to the surface of the article. The method comprises formulating the resin composition for the fabrication of the shaped article with an epoxy compound containing, preferably, at least 2% by weight of the oxirane oxygen in the molecule in an amount of at least 0.05% by weight based on the vinyl chloride-based resin and irradiating the shaped article with ultraviolet light having a substantial energy distribution in the wavelength region of 200 nm or shorter. The shaped article obtained by the inventive method is remarkably insusceptible to the plasticizer bleeding even after prolonged outdoor exposure or irradiation with ultraviolet light having wavelengths longer than 290 nm.
