<p>PROBLEM TO BE SOLVED: To obtain a compsn. having a high sensitizing effect and excellent in development resistance by adding a water-soluble compd. contg. an atom having an external double atomic effect in each molecule. SOLUTION: This compsn. contains a water-soluble azido compd., a water-soluble high molecular compd. and a water-soluble compd. contg. an atom having an external double atomic effect in each molecule. The azido compd. is preferably sodium 4,4'-diazidostilbene-2,2'-disulfonate. The high molecular compd. is preferably polyvinylpyrrolidone or an acrylamide-diacetonacrylamide copolymer. The water-soluble compd. is not especially limited if it contains an atom such as Cl, Br or I and is soluble in water, and tetramethylammonium iodide is, e.g. used.</p> |
