Definitions
- the present invention relates to a process for processing colorv photographic elements and more particularly to an improved processing method in color photography for controlling the gradation of dye images and the graininess thereof.
- a conventionally employed process for processing the usual silver halide, color photographic elements, after exposure, for obtaining color images includes the step of processing the exposed color photographic element in an alkaline solution.
- the solution contains a primary aromatic amine type color developer in the presence of a coupler and forms a color image by the reaction of the coupler and the thus formed oxidation product of the color developer.
- the density of the color photographic image obtained by the abovementioned color development is generally extremely high, by the high extinction coefiicient of the dye, and the gradation thereof is generally hard. Accordingly the phenomenon of hardening in gradation of the color image, incidental to color development for color photographic elements, must be settled.
- the simplest method for overcoming such a difficulty is to reduce the quantity of silver halide in the emulsion layer of the color photographic element to control the gradation to a normal state. Therefore, the content to silver halide in a color photographic element is usually markedly less than that which is practical and general in a black and white photographic element. However, it is not preferable to reduce the quantity of silver halide, since there are substantial drawbacks, namely, graininess becomes coarser and resolving power becomes lower.
- the grain size of the silver halide may be fined.
- the fining of the silver halide particle is inevitably accompanied by a reduction in sensitivity, which makes the employment of such a process dilficult except for a specific purpose.
- German Pat. 1,155,- 675 compounds having a substituted-type active methylene are effective for such a purpose.
- a main object of this invention is to provide a novel gradation controlling compound having better properties than known gradation controlling compounds.
- the inventors have found that the compounds shown by the following general structural formulas have not only very excellent effects in the control of gradation, the improvement of graininess and the increase of resolving power, but also are capable of enlarging effectively the range of gradation control, which contribute to the improvement of the qualities of photographic dye images more effectively than conventional gradation controlling compounds.
- I fi coon 3 wherein X represents H, OH or NH and M represents H, Na, K, NH 01' other mono-valent positive atom or atomic group.
- the optimum amount in which the compound should be used as an additive is influenced by the kind and the concentration of the coupler to be employed, the kind of developing agent, the pH of the processing solution, and the extent of gradation to be controlled, but, in general, the amount of 0.1-3 g. of the compound per one liter of color developer is applicable.
- an amount of the compound less than the above range gives only a poor effect and an amount more than this range tends to reduce the color density too much.
- an amount of 0.8-1.2 g./ liter is preferable.
- the compound of this invention may be applicable for processing a color photographic film or a color photographic printing paper of the type wherein a coupler is incorporated in the emulsion layer of the color photographic element, as well as a color photographic film of the type in which a coupler is incorporated in a processing solution.
- EXAMPLE 1 To a film support of cellulose acetate were applied a red-sensitive gelatino silver bromo-iodide emulsion, a green-sensitive gelatino bromo-iodide emulsion, a yellow filter layer composed of colloidal silver capable of absorbing blue light, and a blue-sensitive gelatino silver bromoiodide emulsion, successively, in this order to provide a multi-layer color photographic film, which was exposed by means of a sensitometer and subjected to the following processings:
- the gradation is shown by the average gradient of the line passing through the points on the characteristic curve corresponding to density 0.4 and density 2.0 and the increase in latitude is shown by the increase in relative value of the difference between the exponential exposure amounts corresponding to density 0.3 and density 2.5 to the value of the standard development. Further, the addition amount is the optimum amount.
- the sensitivity of the magenta coupling layer is increased, the formation of undesirable coupling which results in color contamination is prevented and excellent color reproduction can be obtained.
- EXAMPLE 2 The multi-color photographic film, as in Example 1, was processed after exposure as in Example 1, but in this case the composition of the magenta developer was varied as follows:
- Formula A Formula B Composition A further added with 1 g./liter of sodium 4-amino-salicyalate. The results are shown in the following table.
- the gradation of the magenta color image can be softened, the latitude can be enlarged and high sensitivity is obtained.
- EXAMPLE 3 A gelatino silver bromo-iodide emulsion containing a cyan coupler was applied to a film of cellulose acetate Color development6 min. at 24 C.
- Formula (A) having added to it 1 g./liter of sodium 4-oxysalicylate.
- Formula (A) having added to it 0.8 g./liter of sodium 4-aminosalicylate.
- Formula (A) having added to it 1 g./liter of l-hydroxy-2-naphthoic acid.
- Formula (A) having added to it 0.8 g./ liter of sodium l-hydroxy-6-amino-2-naphthoate.
- EXAMPLE 4 Water to make; .liter. a v I r I To a film of cellulose acetate were appliedared se I I: a result 'of ineasurement after processing it was tive silver bromo-iodide emulsion containing-.21 cyan couobserved that the gradation was improved, the latitude pler, a green-sensitive silver bromo-iodide emulsion .co nenlarged and the colorcontamination was reduced taining a magenta-coupler, a yellow filter layercontaining as. shown in the ,tollowing table.
- First developer same as the first developer in,Example 1 Stopping solution: I Sodium acetateg, Acetic acid-3 ml. Water to make 1 liter.
- a process for processing'color photographic elements employing a color developer containing a member selected from the group consisting of p-phenylenediamine and a derivative thereof, the improvement which comprises controlling the gradation of dye images obtained therein by processing with a developer additionally incorporating at least one member selected from the group consisting of compounds having the formula wherein X is a member selected from the group consisting of H, OH and NH and M is a member selected from the group consisting of H, Na, K, NH other monovalent positive atoms and mono-valent atomic groups.
