Properties of poly (vinyl chloride) membranes containing cadmium pigments, irradiated with UV radiation

Abstract The cadmium pigments were yellow, orange and red pigments. They consisted of cadmium sulphide and cadmium sulphide with zinc sulphide as well as cadmium sulphide with cadmium selenide. Their quantitative composition and specific surface area were examined. The pigments were used to color th...
