Abstract
Abstract Paint compositions for indicating irradiation dose are prepared from chlorine-combined polyester, 5 to 30 percent by weight of a reductive discoloring substance or a mixture of said substances, and/or 0.005 to 2.0 percent by weight of a reducing dyestuff or a mixture of said dyestuffs, in which said chlorine-combined polyester is obtained by a chlorinated dibasic acid or its anhydride as an acid component or a part of an acid component selected from a group consisting of 3-chlorophthalic acid, 4chlorophthalic acid, dichlorinated phthalic acid, tetrachlorophthalic acid, 1,4,5,6,7,7-hexachlorobicyclo-(2,2,1)5-heptene-2,3-dicarboxylic acid, 4-chloro-4-cyclohexene-1,2dicarboxylic acid and the anhydrides corresponding to said acids.
