    摘要： A method of forming a dye image in a photographic silver halide element containing a dye-providing compound and having in a layer thereof an imagewise distribution of catalytic silver which comprises the step of treating the material with a redox amplifying solution comprising a reducing agent and a redox amplification oxidant characterized in that the redox amplification oxidant is removed from the solution after use and the so-treated solution is re-used after the addition of fresh redox amplification oxidant.

    摘要： A process for the redox development of an imagewise exposed photographic recording material comprises developing the photographic material in a redox developer/amplifier solution containing peroxide as an oxidizing agent, hydroxylamine as an antioxidant, and to improve the stability of the solution under aeration conditions, an effective amount of a mono or di-N-substituted hydroxylamine. The molar ratio of hydroxylamine to N-substituted hydroxylamine may be from 1:200 to 100:1. The substituents in the mono- or di-N-substituted hydroxylamine may be substituted or unsubstituted monovalent organic groups having 1 to 12 carbon atoms.

    摘要： A method of color processing in which an imagewise exposed color photographic silver halide material is processed by a procedure which comprises treating it with a color developer solution and then with a developer/amplifier solution containing a color developing agent and hydrogen peroxide in which said solutions are replenished so that the overflow from the developer/amplifier solution is treated to remove hydrogen peroxide and used to form the sole replenisher for the color developer solution while the overflow from said color developer solution is disposed of as the net overflow of the two processing solutions.

    摘要： A method for processing photographic silver halide color negative film and color negative paper each through its own color developing solutions wherein the paper color developing solution is replenished and the overflow from this replenished solution is used to replenish the film color developing solution and wherein (a) the color paper is based on substantially pure silver chloride emulsions and contains no more than 1% molar silver bromide based on total silver halide and (b) both color developing solutions and the replenisher are free from benzyl alcohol.Apparatus for carrying out the above-described method comprises a series of processing stations and means for advancing the photographic material being processed through the apparatus wherein there is provided means for collecting the overflow from the paper developer station and means for passing it directly or indirectly to the film processing station.

    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.
