Definitions
- This invention relates to photographic rinse baths for removing color developer stains from azine dyestuif images following color forming development with ZA-diaminoaniline developing agents.
- azine dyestuif images are produced by color developing silver halide emulsions containing azine color formers with a ZA-diaminoaniline developing agent. The procedure of this process is fully described in U. S. P. 2,486,440.
- the ZA-diaminoaniline developing agents employed therein possess one disadvantage which causes a somewhat serious problem.
- the disadvantage occurs in the development of the multilayer color film of the azine type and is manifested especially when the aromatic trianiino developing solution is old and badly oxidized by leaving a developer stain in the processed film.
- This stain in most cases is quite substantive to gelatin but can under certain circumstances be to some extent removed by excessively long water washing after color development.
- This developer stain is observed particularly in the highlights or Whites of the processed film. In the color developed areas of the film, it produces a serious loss in color brilliance and a degradation of color rendition.
- the developer contributes in no small degree to the loss of storage stability of the final color image, including both the socalled light, humidity, and heat fading characteristics.
- rinse baths consisting of aqueous solutions of water soluble open-chain mono-, di-, and tribasic acids, such as acetic,
- the above objects are accomplished by treating an azine multilayer color film, after color forming development with an aqueous rinse bath containing from 0.1 to 10% of formaldehyde and from 0.1 to 10% of a Water-soluble acid, such as hydrochloric, phosphoric, acetic, maleic, citric, acrylic, oxalic, tartaric, and the like.
- a Water-soluble acid such as hydrochloric, phosphoric, acetic, maleic, citric, acrylic, oxalic, tartaric, and the like.
- the pH of the resulting rinse bath is immaterial and in these concentrations, and in the presence of formaldehyde, the acid does not form an insoluble complex with the residual ZA-diaminoaniline developing agent retained by the film, i. e., does not precipitate it upon the film or in the layers thereof.
- the color formers utilized contain a group rendering them non-migratory in the emulsion. Examples of such compounds are:
- Color formers capable of producing magenta dyestuff images are also described in the above identified application and in USP 2,524,741.
- these color formers are 6-halogen-8-hydroxyquinolines, and particularly those which are non-migratory in the emulsions.
- Examp1es of the latter type compounds are:
- Color formers for the cyan image are also described in USP 2,570,1 6, issued October 2, 1951, and in USP 2,445,252, issued July 13, 1948.
- these color formers are aryl-J-acid derivatives, particularly those containing a group rendering the color former non-migratory in the emulsion.
- Examples of the latter compounds are: dodecyl urethane of fi-sulfoethyl-J-acid tetradecyl urethane of p-anisyl-J-acid Z-hexadecyl urethane of phenyl-J-acid 4-stearoylamino-J-acid, and the like.
- Example I A red sensitive emulsion containing phenyl-J- acid-N-octadecyl urethane was exposed and the latent image developed in a black and white developer, re-exposed, and the residual silver halide developed in a solution of the following composition:
- the film was washed, bleached in a ferricyanide bleach, and fixed in an acid hardening solution. There is obtained a cyan positive dye image completely free from stain and stable against accelerated adverse storage conditions.
- Example I I Grams Sodium carbonate (monohydrate) 40 Sodium sulfite 60 Potassium bromide 5 Pyridine 16 Benzylamine 1 4 (B hydroxyethylamino) 6 phenyl amino-metanilic acid 5 Water to make 1000 cc.
- the film was washed, bleached in a ferricyanide bleach, and fixed in an acid hardening fixer solution. There was obtained a multicolor film containing stain-free positive dye images of excellent brilliance and freedom from color degradation.
- Example III An integral tripack of essentially the same composition as in Example II was exposed and color developed for minutes to a negative image in a solution of the following composition:
- Hydroxylamine hydrochloride 1 4 4,8 hydroxyethylamino) -6-benzylamin0- metanilic acid 6 Water to make 1000 cc.
- the film was washed, bleached in a ierricyanide bleach, and fixed in an acid hardening hypo solution. There was obtained a brilliant negative dye image completely free from stain and color degradation. The negative did not acquire additional stain nor become subject to color degradation during three weeks accelerated aging at relative humidity and F.
