PURPOSE:To simplify soln. preparing work by mixing a concd. soln. for a replenisher consisting of a part contg. a dialdehyde type hardener and an alkaline part contg. a specified 3-pyrazolidone type developing agent before replenishment and by replenishing the mixed soln. optionally together with water in accordance with the progress of processing of a sensitive material. CONSTITUTION:A concd. soln. for a replenisher consisting of a part contg. a dialdehyde type hardener and an alkaline part contg. a developing agent represented by formula I is mixed before replenishment. A sensitive material is processed by replenishing the mixed soln. optionally together with water in accordance with the progress of processing of the sensitive material. In the formula I, R is aryl group, each of R1-R4 may be the same or different and is H atom, alkyl, aryl or aralkyl group, and when R is unsubstd. phenyl group, R1-R4 are not simultaneously H atom. Thus, soln. preparing work can be further facilitated. |
