Abstract
A composition for irradiation with an ionizing radiation, characterized by comprising: (a) 0.01 to 30 parts by weight of a soluble aniline polymer which comprises one or both of the repeating units represented by the following general formulae (1) and (2), said repeating units being included at least 80% of the total repeating units, possesses a weight average molecular weight of not less than 10,000, and is solid at room temperature; and (b) 100 parts by weight of a solvent, ##STR1## wherein R.sup.1 to R.sup.4 represent an electron-donating group, Y.sup.1 to Y.sup.4 represent --SO.sub.3 -- or --COO--, and M.sup.1 to M.sup.4 represent a hydrogen ion, an ammonium ion, an a1kyl ammonium ion with 1 to 8 carbon atoms, an aromatic ammonium ion, or a quaternary ion of an aromatic heterocyclic ring.
