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

反転処理用写真処理溶液およびその処理溶液を用いるポジ画像形成方法

Abstract

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.
