Definitions
- This invention relates to a method of treatment of a photographic light-sensitive material, in particular, by the use of an improved developer.
- a chelating agent such as ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), 1,3-diamino-Z-propanoltetraacetic acid as disclosed in United States Pat. 2,875,049, or condensed polyphosphoric acid, for example, as sold under the trade name of Calgon.
- EDTA ethylenediaminetetraacetic acid
- NTA nitrilotriacetic acid
- condensed polyphosphoric acid for example, as sold under the trade name of Calgon.
- this attempt is unsatisfactory because although the addition of the known chelating agents to a developer results in a softening of hard water, the addition does not prevent stains.
- some of these chelating agents accelerate catalytically the oxidation of a developing agent thus shortening the life of the developing solution (see Photographic Science and Engineering 3, 49 (1959)), and accordingly, the use of chelating agents is limited considerably.
- inositolpolyphosphoric acids or their alkali metal salts used in this invention are the following compounds:
- the compound of this invention is added in a proportion of from 10 mg. to 10 g. for each 1000 ml. of a developing solution. Preferably from 0.1 to 3 g. is used.
- the inositolpolyphosphoric acid or its alkali metal salt of the invention can be used together with the above described known compounds.
- a developing solution containing the additive of this invention is applicable to any photographic light-sensitive materials, in particular, color photographic lightsensitive materials, in particular, color photographic lightsensitive materials, containing the yellow coupler described in United States Pat. 3,409,439 and British Pat. No. 1,113,038, the magenta coupler described in United States Pat. 3,337,344 and British Pat. No. 1,142,553 and the cyan coupler described in United States Pats. 2,423,730, 2,474,- 293, and 2,801,171 and the light-sensitive material de scribed in French Pat. No. 1,576,417.
- EXAMPLE 1 A color photographic printing paper having, on a baryta paper as a support, a blue-sensitive silver iodobromide emulsion layer containing benzoylaceto-Z-chlorO-S- dodecyloxycarbonylanilide as a yellow coupler, a gelatin intermediate layers, a green-sensitive silver chlorobromide emulsion layer containing 1-phenyl-3-[3-(N-butylcaprylamidepropionamide) ]--pyrazolone as a magenta coupler, a gelatin intermediate layer, a red-sensitive silver chlorobromide emulsion layer containing 1-hydroxy-2-[3-(2, 4"-di-t-amyl-phenoxy)propyl]naphthamide as a cyan coupler and a gelatin protective layer was treated with the developing solution described in The British Journal of Photography, Sept. 27, 1968, p. 838, while adding the compound of the invention or ferric sulf
- Developer-2 0.1 g. of ferric sulfate was added to 1000 ml. of Developer-1.
- Developer-3 0.1 g. of ferricsulfate and 2 g. of Calgon (trade name) were added to 1000 ml. of Developer-l.
- Developer-4 0.1 g. of ferric sulfate and 2 g. of EDTA- 2Na were added to 1000 ml. of Developer-1.
- Developer-5 0.1 g. of ferric sulfate and 2 g. of NTA were added to 1000 ml. of Developer-1.
- Developer-6 0.1 g. of ferric sulfate and 2 g. of Compound 1 were added to 1000 m1. of Developer-l.
- EDTA-2Na disodium ethylenediaminetetraacetate.
- NTA nitrilotriacetic acid
- Developer-2 to Developer6 were also adjusted to pH 10.6.
- the stop-fixing bath contains ammonium thiosulfate
- the bleaching bath contains potassium ferricyanide
- the hardener fixing bath contains ammonium thiosulfate and formalin
- the stabilizing bath contains sodium metaborate.
- the following table shows the degree of staining when treated with Developer-1 to Developer-6. Since the stain formed by this treatment was brown, it was shown by the blue optical density on a non-exposed area.
- a color light-sensitive material having, on an acetate film support, a blue-sensitive silver iodobromide emulsion layer containing a yellow coupler, a gelatin intermediate layer, a red-sensitive silver chlorobromide emulsion layer containing a cyan coupler, a gelatin intermediate layer, a green-sensitive silver chlorobromide emulsion layer containing a magenta coupler and a gelatin protective layer was treated at 21 C. for 12 minutes with the developing 4 solution described in Journal of the SMPTE 61, 12, 667
- Developer-8 2 g. of hydroxylamine (hydrochloride) was added to 1000 ml. of Developer-7.
- Developer-10 1 g. of Compound 4 was added to 1000 ml.
- Developer-11 1 g. of Compound 5 was added to 1000 ml.
- Developer-l2 1 g. of Compound 6 was added to 1000 ml.
- Developer-8 to Developer-12 were also adjusted to pH of 10.65.
- the treatment was carried out in the order of prebath rinse development rinse fixing washing leaching washing fixing washing -stabilizing drying.
- the prebath contained caustic soda and the bleaching bath contained potassium dichroir iate.
- the other baths were similar to those of Example 1.
- the following table shows the degree of fog formed when treated with Developer-7 to Developer-12. This treatment was carried out using a tray.
- the aerial fog appearing in any of the cyan, magenta and yellow layers, particularly strong in the cyan layer, is represented by the red optical density on a non-exposed area.
- Developer No. Red optical density
- Developer-8 there was a considerable air for inhibiting effect but not so suflicient and the sensitivity was less than in using Developer-7.
- Developer-9 to Developer-l2 containing the additives of the invention was substantially free from aerial fog, had no influence upon the photographic properties and was so stable that decomposition did not occur.
- EXAMPLE 3 A photographic printing paper having a silver chlorobromide emulsion layer on baryta paper was treated at 20* C. for seconds with each of the following Developer-l3 to Developer-16.
- Developer-14 0.2 g. of ferric sulfate' was added to 1000 m1. of Developer-13.
- Developer-15 0.2 g. of ferric sulfate and 0.5 g. of Compound 1 were added to 1000 m1. of Developer-13.
- Developer-16 0.2 g. of ferric sulfate and 0.5 g. of Compound 3 were added to 1000 ml. of Developer-'13.
