ABSTRACT Surface-treated vinyl chloride polymer material including an adhering hydrophilic layer. A corona -discharge surface treated vinyl chloride polymer material including an adhering hydrophllic layer, characterized in that the bare vinyl chloride polymer surface has been treated with a corona discharge to bring its wetting behaviour expressed as surface tension measured by a test T as described to a value of at least 50 mN/m, and that on said treated surface a hydrophilic layer containing dispersed in a hydrophilic colloid binder colloidal silica in a weight ratio range of 5/1 to 1/2 has been applied.
