PURPOSE:To form acid-resistant, water-resistant and water-repellent image by coating a soln. dissolving water-soluble polyacrylamide (including a copolymer of the same and vinyl acetate etc.) and formaline condensate of diazo-diphenylamines on an Al plate or the like then drying the same. CONSTITUTION:The photosensitive composition prepd. by mixing a suitable amount of an aqueous soln. contg. about 40% the condensate of diazo-diphenylamines and formalin with an aqueous soln. of about 10-40% a water-soluble polyacrylamide or water-soluble copolymer of vinyl acetate, acrylic ester, etc. and acrylamide and further adding a suitable amount of water thereto is coated on a metal or resin plate or the like and is dried, whereby a photosensitive image forming material is manufactured. In this way, the acid-resistant, water-resistant and water- repellent images which can form images by rinsing after exposure is obtained without using any Cr compound etc. which are sources for pollution. |
