Definitions
- This application describes a colour development process for colour silver halide photographic material, wherein the material after development is treated with a bleachfix solution which contains a mild oxidising agent, a silver halide solvent and as a bleach-fix accelerator a watersoluble complex consisting of a specified metal and selenourea, a specified N-alkyl substituted selenourea or a specified selenosemicarbazide.
- a bleachfix solution which contains a mild oxidising agent, a silver halide solvent and as a bleach-fix accelerator a watersoluble complex consisting of a specified metal and selenourea, a specified N-alkyl substituted selenourea or a specified selenosemicarbazide.
- This invention relates to the processing of photographic material comprising silver halide emulsion layers to yield material having colour dye images therein.
- a developable silver salt image is developed with an aromatic primary amino developing agent of the paraphenylene diamine type (a so-called colour developer) in the presence of a compound (a so-called colour coupler) which will combine with the oxidation products of the colour developer to form an azomethine or quinoneimine dye.
- the dye is thus formed in situ with the developed silver image.
- the product must be treated with a bleach bath and a fixing bath or a combined bleach-fix bath thereby to remove silver and any residual silver halide or other silver salt, leaving in the product only the dye image.
- the photographic material comprises at least one silver halide emulsion layer which includes as a dispersion therein an organic dyestulf or the type which can be destroyed (or bleached) by finely divided silver in a suitable treatment bath.
- the organic dyestulf is usually an azo dye.
- Most commonly three such silver halide emulsion layers are present, each of which is sensitive to a different region of the visible spectrum and each of which contains a different azo dye.
- the usual processing sequence for the production of a dye image in the material is after an imagewise exposure to develop the material in a black and white developer. The development is then stopped and the unexposed silver halide is fixed out.
- the material is treated in a dye-blech bath which oxidises the silver image and simultaneously reduces (bleaches) the dye in the region of the silver image.
- the silver salts and any residual silver must then be removed. This is usually accomplished by washing the material after its treatment in the dye-bleach bath and then treating it in a bleach bath followed by a fixing bath or treating it in a combined bleach-fix bath.
- the photographic material then contains a dye image only; this dye image being usually a direct positive reproduction of the original.
- the amount of residual silver left after the dye-bleach ice step is not negligible because this material requires to be processed so that the dye-bleach step is terminated before all the image silver has been used in reducing the dye.
- an elfective silver bleach step succeeds the dye-bleach step in order to ensure that the residual silver is removed as completely as possible from the material.
- a bleach-fix bath comprises a mild oxidising agent for example a ferric chelate complex, a cupric complex a salt or a cobalt (III) complex together with a silver halide solvent or fixing agent for example a watersoluble thiosulphate or a water-soluble thiocyanate.
- a mild oxidising agent for example a ferric chelate complex, a cupric complex a salt or a cobalt (III) complex
- a silver halide solvent or fixing agent for example a watersoluble thiosulphate or a water-soluble thiocyanate.
- Strong oxidising agents cannot be used because they tend to oxidise the silver halide solvent.
- Stable bleach-fix solutions comprising ferric chelate complexes and sodium thiosulphate may be obtained but because of the weak oxidising power of the ferric chelate complex such bleach-fix baths can only be used commercially for the processing of photographic materials with a fairly low silver content.
- selenourea certain N-alkyl substituted selenoureas and certain substituted selenosemicarbazides as bleach-fix accelerators in a bleach-fix step which can be used in the processing of colour photographic material which have a relatively high silver content, for example colour negative material and colour reversal material. It has now been found that certain metal complexes of these compounds may be used instead of the compounds as bleach-fix accelerators.
- a bleach-fix step which comprises treating the photographic material with a stable bleach-fix bath which comprises an aqueous solution of a mild oxidising agent and a silver halide solvent which is either a water-soluble thiosulphate or a water-soluble thiocyanate in the presence of a bleach-fix accelerator which comprises a water-soluble complex consisting of a metal selected from iron, cobalt, nickel, copper, zinc, palladium, silver, cadmium, indium, tin, antimony, platinum, gold mercury, lead and bismuth and (a) selenourea, (b) an N-alkyl substituted selenourea of the general Formula I:
- R R and R are hydrogen atoms or alkyl groups, at least one of them being a hydrogen atom, or (c) a selenosemicarbazide of the general Formula II:
- stable bleach-fix bath which comprises an aqueous solution of a mild oxidising agent and a silver halide solvent is meant a bleach-fix bath wherein the oxidising agent is strong enough to bleach the silver but is not strong enough to oxidise the silver halide solvent, i.e. the thiocyanate or the thiosulphate, to an appreciable degree.
- ferric chelate complex is meant a co-ordination compound of the ferric ion and a compound which comprises nitrogen and/or oxygen-containing co-ordinating groups.
- the most important co-ordinating groups are amino, heterocyclic nitrogen, carboxyl and carbonyl groups.
- the preferred ferric chelate complex for use in the bleach-fix step of the present invention is a ferric ethylenediaminetetraacetic acid complex. It is to be understood that this compound may be usedas such in the preparation of a bleach-fix bath or it may be formed in situ in a bleach-fix bath by ethylenediaminetetraacetic acid reacting with a ferric salt, e.-g. ferric chloride. In Example I which follows the ferric ethylenediaminetetraacetic acid complex has been formed in situ.
- ferric chelate complexes which may be used in the present invention are for example pyridine-2:6 dicarboxylateferrate (III) complex, iminodiacetatoferrate (III) complex and nitrilo-triacetate-ferrate (III) complex.
- R R R HN CSe M] zy wherein R R R are each hydrogen atoms or alkyl groups, at least one of them being a hydrogen atom, M is one of the metals in the list hereinbefore set forth, Z is an anion, z is the valency of the anion and y is the valency of the complex cation.
- the bleach-fix accelerators may be present in the wash bath which succeeds the dye-bleach treatment bath and precedes the bleach-fix bath but the bleach-fix accelerators should not be present during the dye-bleach treatment as they can interfere with this treatment step. Thus the bleach-fix accelerators should not be present initially in the silver-dye-bleach photographic material.
- bleach-fix accelerators of use in the present invention are not soluble in water unless the water comprises a thiosulphate.
- the bleach-fix accelerators of use in the present invention are added to a bleach-fix bath which comprises thiosulphate or to a stop-fix bath which comprises thiosulphate.
- a stable bleach-fix bath which comprises an aqueous solution of a mild oxidising agent, as hereinbefore defined, a water-soluble thiosulphate and a bleach-fix accelerator which is either a selenosemicarb azide-metal complex as hereinbefore defined or a selenourea-metal complex as hereinbefore defined.
- the mild oxidising agent is a ferric chelate complex or a diaquo-tetraamine-cobalt (III) complex.
- the concentration of selenosemicarbazide-metal complex or selenourea-metal complex present in the bleach-fix bath is greater than 1 mg. per litre of bleach-fix bath.
- the most preferred amount being t1)5'0hmg. of bleach-fix accelerator per litre of bleach-fix
- the concentration of selenosemicarbazide-metal complex or selenourea-metal complex present in the stop-fix bath, stop bath or in a wash bath is greater than 1 mg. per litre of the solution.
- the selenourea-metal complexes of use in the present invention are more resistant to air oxidation and photochemical decomposition than the selenoureas from which they are prepared.
- the metal-complex compounds may be stored under normal conditions and dry-packed with only a minimum risk of the compounds deteriorating. On the other hand selenoureas stored under normal conditions or dry-packed soon turn first pink and then black probably 10 same time showed no analytically detectable decompo- 20 sition.
- Selenosemicarbazide metal complexes offer similar advantages.
- the selenourea-metal complexes may be prepared as follows.
- a given volume of a 0.1 molar solution of the metal salt is prepared by dissolving the required quantity of metal salt in water or in a relatively strong acid solution.
- An acid solution is necessary when salts of easily hydrolysed metal ions are involved, e.g. bismuth and antimony).
- This solution of the metal salt is added to a volume of 0.3 molar solution of the selenourea in 2 normal acid.
- the volume of the selenourea solution used is such that the molar ratio between the selenourea and the metal ion should be slightly greater than 2. This addition is carried out at 40 C. and, in the case of easily oxidised metals, all the preparation should be carried out under nitrogen.
- the complex salt precipitates soon or a few minutes after cooling.
- the selenosemicarbazide metal complex ie the complexes formed between the list of metals hereinbefore set forth and the compound of Formula II, may be prepared similarly except that the molar ratio between the selenosemicarbazide and the metal ion may be greater than 1.
