发明名称 Photographic wash solution and process
摘要 A photographic washing bath comprises a chamber containing a wash solution for a silver halide photographic material having a pH of less than 7 and comprising water having dissolved therein an oxidizing agent, said oxidizing agent having an oxidizing potential of at least 1 volt and being in a concentration of from 0.05 to 2 Molar. The oxidation potential of the oxidizing agent is preferably at least 1.2 volts and may be hydrogen peroxide or a source of hydrogen peroxide, a persulphate, a perborate, a bromate, or an iodate. A washing process using the invention is suitable for being carried out in same chamber as the development and fixing stages in which case hydrogen peroxide is the preferred oxidizing agent because any peroxide remaining at the end of the wash stage can be removed by evaporation, thereby avoiding risk of contamination of the next stage to be carried out in the chamber..
