摘要： PURPOSE:To obtain a two-component type diazo photosensitive material giving an azo dye image with superior fastness and fixablility even by semidry development by adding a photodegradable diazonium salt, a specified coupling component and an acid stabilizer. CONSTITUTION:A photodegradable diazonium salt (A) such as 4-diazo-2,5-dibutoxy-N,N-diethylaniline is mixed with a coupling component (B) represented by formula I (where R1 is lower alkylene; each of R2, R3 and R4 is lower alkyl; R3 and R4 may bond to each other to form a heterocyclic ring together with N; and X is an anion) and an acid stabilizer (C) such as maleic acid, and the mixture is applied to a substrate to obtain the desired two-component type diazo photosensitive material. The component B is easily prepd. by reacting amine represented by formula II with an alkylating agent such as alkyl iodide or alkyl ester of p-toluenesulfonic acid.

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.
