Definitions

the invention relates to a bleaching bath which is suitable for processing color photographic silver halide materials and which is particularly environmentally friendly.
Iron complex salts of aminopolycarboxylic acids for example the iron ammonium complex salt of ethylenediaminetetraacetic acid, are usually used to bleach the silver formed during the development of color photographic materials. This and similar complexing agents that are also used are only very slowly biodegradable.
bleaching baths containing iron complexes of readily biodegradable complexing agents such as nitrilotriacetic acid are used for bleaching color photographic materials under the usual conditions at pH 6 to 8, they lack sufficient bleaching capacity.
the object of the invention was to provide a bleaching bath which is suitable for processing color photographic silver halide materials and which contains readily biodegradable constituents and has a sufficient bleaching effect.
Preferred compounds within the formula I are nitrilotriacetic acid and nitrilomonopropionediacetic acid of the formulas N- (CH2COOH) 3 and (HOOC) -CH2) 2-N-CH2-CH2-COOH.
complexing agent can be conventional complexing agents such as ethylenediaminetetraacetic acid or propylenediaminetetraacetic acid. Only the complexing agents according to the invention are preferably used.
bleaching baths also contain a halide for rehalogenating the silver.
the halides of the bleaching baths are in particular the chlorides and bromides of sodium, potassium and ammonium.
the bleach bath When ready for use, the bleach bath contains 0.05 to 1.5 mol / l halide.
the bleaching bath according to the invention is particularly suitable for color photographic silver halide recording materials whose silver halide emulsions consist predominantly of AgBr, AgBrI, AgBrCl or AgCl.
the color photographic material preferably contains on a reflective or transparent support (for example paper coated on both sides with polyethylene or cellulose triacetate film) at least one blue-sensitive, at least one green-sensitive and at least one red-sensitive silver halide emulsion layer, to which at least one yellow coupler, at least one magenta coupler and at least one cyan coupler in the order given assigned.
the bleaching bath according to the invention is used within the usual processing method for color photographic silver halide materials, which consists of the steps of imagewise exposure, development, optionally stopping, bleaching, fixing or bleach-fixing, watering, optionally stabilizing and drying, the watering being omitted if at the end of Processing a stabilizing bath is applied.
the processing method can be carried out continuously with constant regeneration of the individual processing baths.
the bleaching baths listed in the examples were examined for their bleaching behavior (residual silver in the processed material).
the exposed step wedge of the photographic material which was subsequently processed as described below, was examined for residual silver in the image blackness using an infrared silver detector PM 8030 from Photo-Matic, Denmark.
a color photographic recording material was produced by applying the following layers in the order given to a support on paper coated on both sides with polyethylene. The quantities given relate to 1 m 2 . For the silver halide application, the corresponding amounts of AgNO3 are given.
a step wedge was exposed on the photographic material described above and processed as follows: The individual processing baths had the following composition: For the result of the residual silver determination, see Tab. 1.
Example 1 The exposure and processing were carried out as described in Example 1.
the developer had the same composition as in Example 1. Fixing bath as in example 1
Example 1 The exposure and processing were carried out as described in Example 1.
the developer had the same composition as in Example 1. Fixing bath as in example 1
Table 1 shows the good bleaching action of the bleaching bath A according to the invention, which contains a biodegradable complexing agent.
the bleaching effect corresponds to that of the usual bleaching bath C, which contains the biodegradable EDTA.
the bleaching bath B which is composed essentially like bleaching bath A, but lies in the pH range prescribed for EDTA bleaching baths, on the other hand only bleaches insufficiently.
a step wedge was exposed on the photographic material described above and processed as follows:
the processing baths had the following composition:
the result with regard to residual silver is shown in Table 2 below.
the color image produced was of the type.
the bleaching action of the bleaching bath D according to the invention with a biodegradable complexing agent corresponds to the bleaching action of the customary bleaching bath F with the biodegradable complexing agent EDTA.
the bleaching bath E which is composed essentially like bleaching bath D, but has a pH value customary for EDTA bleaching baths, on the other hand only bleaches insufficiently.
the bleaching tests carried out showed that the bleaching bath D according to the invention does not lead to the formation of leuco blue-green dye, while in a conventional bleaching bath with EDTA there are significant losses of blue-green dye at the corresponding pH.
