摘要： PURPOSE:To enhance image quality, by incorporating an acid stabilizer, a metallic ion sequestering agent, a water holding agent, and a phytic acid exhibiting a superior action as a color tone stabilizer, etc. in a photosensitive layer contg. a photosensitive diazonium salt, a coupler, etc. CONSTITUTION:0.5-7pts.wt. phytic acid is incorporated in 1pt.wt. photosensitive diazonium salt, such as 4-diazo-N,N-dimethylaniline or 4-diazo-N-ethyl-N-beta-hydroxyethylaniline. When needed, further, a coupler, such as pyrocatechol or resorcinol, a stabilizer adjuvant, and a dye are added, and the mixture is dissolved or dispersed in water or the like solvent to prepare a photosensitive compsn. A base, such as tissue paper or coated paper, is coated with said photosensitive compsn. with a roll, a sprayer, or the like, and dried to obtain the intended diazo photosensitive material.
