Photographic processing liquid for reversal processing, and positive picture forming method using the same



PROBLEM TO BE SOLVED: To make reducible or substantially eliminable a fault of a chemical fogging agent by incorporating a specified compd. and a bi-nucleophilic agent. SOLUTION: In the soln., the compd. expressed by the formula and the bi- nucleophilic agent are incorporated. In the formula, (A) is a group which can be adsorbed on the surface of halogenated silver, L is a connecting group, (r) is 0 or 1, R1 and R2 are independently an alkyl or aryl group. The R1 and R2 may be independently a substd. or unsubstd. 1-12C alkyl group. The linear or branched, unsubstd. or substd. alkyl group or cycloalkyl group are exemplified as the alkyl group. The R1 and R2 may be independently a 1-4C alkyl group as a desirable situation. The bi-nucleophilic agent is the agent containing two active nucleophilic sites. The bi-nucleophilic agent is, for example, hydroxylamine, hydrogen peroxide, hydrazine or substd. hydrazine.
