Summary: | 1,234,172. Radiation indicator paints. " MEDIMPEX " GYOGYSZERKULKERESKEDELMI VALLALAT. 13 Jan., 1969 [18 Jan., 1968], No. 1983/69. Heading C3P. [Also in Division H5] A radiation dose indicator paint for hydrophobic surfaces, e.g. polyethylene, comprises an aqueous emulsion of a vinyl chloride copolymer and 0À5-10% by weight based on the emulsion of the yellow dye 41-aniline-azobenzene-msulphonic acid. In the examples are used vinyl chloride-vinyl acetate copolymer emulsion containing glycerol and vinyl chloride-vinylidene chloride-methyl acrylate copolymer emulsion containing also vinyl chloride-vinyl acetate pearl copolymer and chlorobenzene.
