Description

Description: FIELD OF THE INVENTION The present invention relates to a color image forming method using a silver halide color light-sensitive material, and in particular, an improved method of using a color coupler allows the use of benzyl alcohol. And a color image forming method in which the processing time is shortened.

(Prior Art) A silver halide color light-sensitive material has a multi-layered photosensitive layer consisting of three types of silver halide emulsion layers selectively sensitized to have sensitivity to blue light, green light and red light. It is coated on the support. For example, so-called color photographic paper (hereinafter referred to as color paper) has a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer, which are coated in order from the normally exposed side, and further between each photosensitive layer. Etc., an intermediate layer and a protective layer which prevent color mixing and absorb ultraviolet rays are provided.

In order to form a color photographic image, photographic couplers of three colors of yellow, magenta and cyan are contained in the photosensitive layer, and the exposed light-sensitive material is color-developed with a so-called color developing agent. An oxidation product of an aromatic primary amine gives a color-forming dye by a coupling reaction with a coupler, but the coupling rate at this time is as high as possible, and a coloring property that gives a high coloring density within a limited developing time is obtained. Good ones are preferred. Furthermore, the coloring pigment is
All of them are required to give a color photographic image having good color reproducibility with a fresh cyan, magenta, and yellow dye having little secondary absorption.

On the other hand, the formed color photographic image is required to have good storability under various conditions. In order to meet this requirement, the fading or discoloration speed of the chromophores of different hues should be slow, and the fading speed should be as uniform as possible over the entire image density, and the color balance of the residual dye image should not change. is important.

In order to solve these problems, a so-called oil-soluble coupler has been proposed as a coupler, which is dissolved in an organic solvent having a high boiling point or a low boiling point, emulsified and dispersed and contained in an emulsion layer. When these couplers are used, the lipophilicity of the color developing agent is low, so that it is difficult for the color developing agent to penetrate into the oil droplets dispersed in the coupler, and the color density is lowered. For this reason, various developing agent penetrants have been investigated, and particularly, a method of adding benzyl alcohol to a color developing solution to accelerate color development has a large effect of promoting color development, and therefore color photographic light-sensitive materials, particularly color paper Widely used in processing.

However, when benzyl alcohol is used, since it has low water solubility, diethylene glycol, triethylene glycol, alkanolamine, etc. are required as a solvent. However, since these compounds including benzyl alcohol have high pollution load values of BOD and COD, it is preferable to remove benzyl alcohol for the purpose of reducing the pollution load.

Further, even if the solvent is used, it takes time to dissolve the benzyl alcohol. Therefore, it is better not to use benzyl alcohol for the purpose of reducing the preparation work.

Further, when benzyl alcohol is brought into a bleaching bath or a bleach-fixing bath which is a post-bath, it causes the formation of a leuco dye which is a cyan dye, which causes a decrease in color density. Further, since the washing-out speed of the developer component is delayed, the image storability of the processed light-sensitive material may be adversely affected. Therefore, it is preferable not to use benzyl alcohol for the above reasons.

In the conventional color development, it was generally processed in 3 to 4 minutes, but it is desired that the processing time be shortened due to the recent shortening of delivery time for finishing and reduction of lab work. Was there.

However, when benzyl alcohol, which is a color-forming accelerator, is removed and the development time is shortened, it is inevitable that the color density is remarkably lowered.

In order to solve this problem, various color development accelerators (for example, US Pat. Nos. 2,950,970 and 2,515,147) are used.

As described above, no method has been found for obtaining a sufficient color image in a short time using a color developing solution that does not substantially contain benzyl alcohol.

(Problems to be Solved by the Invention) An object of the present invention is to provide a color image forming method in which a color photosensitive material using an oil-soluble coupler is treated in a short time with a color developer containing substantially no benzyl alcohol. Further, it is to provide a color image forming method having good color reproducibility and good image storability.

As the average particle diameter, a value measured based on the dynamic light scattering method is used. An example of the measuring device is Nanosizer manufactured by Coulter, England.

In the general formula [I] or [II], those having a total sum of carbon atoms of W ₁ and W ₂ or W ₁ and W ₂ and W ₃ of about 8 or more have a dielectric constant of 4.00 or more (25 ° C., 10 KHz). The permittivity is based on the transformer bridge method (Ando Electric TRS-
It can be easily obtained by measuring at 10T. When these W ₁ , W ₂ and W ₃ further have a substituent, the substituent may be 1 or 2 or more. It may be a group containing a linking group selected from —CON, —R ⁸ N (R ⁸ represents a divalent to hexavalent group formed by removing a hydrogen atom from a phenyl group) and —O—.

In the general formula [I] or [II], the alkyl group represented by W ₁ , W ₂ or W ₃ may be linear or branched. For example, methyl group, ethyl group, propyl group, butyl group, pentyl group, hexyl group, heptyl group, octyl group, nonyl group, decyl group, undecyl group, dodecyl group,

The substituents permissible for these alkyl groups will be described by taking the case of the above-mentioned general formula [I] as an example. Examples thereof include a halogen atom, a cycloalkyl group, an aryl group and an ester group. for example halogen (F, Cl, Br) substituted product _{(-C 2 HF 4, -C 5} H 3 F 8, -C 9 H 3 F 16, -C 2 H 4 Cl, -C 3 H 6 C

Preferably, these high boiling point organic solvents substituted with W ₁ , W ₂ , or W ₄ substituents have a dielectric constant of 5.0 at 25 ° C.
It is preferable that the viscosity is 0 or more and the viscosity at 25 ° C. is 20 Cp or more. It is surprising that a compound satisfying this condition improves the color developability without impairing the absorption and other properties of the color forming dye, and the reason is not clear, but it is probably high boiling point organic solvent having a high dielectric constant. Is considered to be due to the large uptake of the color developing agent, and the high boiling organic solvent having a medium viscosity weakens some adverse effects of the coupler and the silver halide in the oil droplet.

In the present invention, the high boiling point organic solvent represented by the general formula [I] or [II] may be used in any amount depending on the kind and the amount of the coupler to be used. The organic solvent / coupler ratio is preferably 0.05 to 20.

If necessary, a low boiling point solvent or a water-miscible organic solvent may be used, and these solvents are removed by volatilization by drying, washing with water or the like. In the case of this method, it is preferable to use a surfactant together. Generally, in order to reduce the particle size of the lipophilic fine particles, selection of the type of surfactant, increasing the amount of surfactant used, increasing the viscosity of the hydrophilic colloid solution, and the organic layer in which the compound is dissolved To reduce the viscosity of the emulsion by using a low boiling point solvent together, or to increase the cutting force such as increasing the rotation of the stirring blade of the emulsifier, or to increase the emulsification time.

The graininess can be improved by using a coupler in which the color forming dye has an appropriate diffusibility. Such dye-diffusing couplers are exemplified by magenta couplers in U.S. Pat. No. 4,366,237 and British Patent No. 2,125,570, and also in European Patent No. 96,570 and West German Application No. No. 234,533, specific examples of yellow, magenta or cyan couplers are described.

Various couplers used in the present invention can be used in combination of two or more kinds in the same layer of the photosensitive layer in order to satisfy the properties required for the light-sensitive material, or two or more layers in which the same compound is different. Can also be introduced.

The standard amount of the color coupler used is in the range of 0.001 to 1 mol per mol of the light-sensitive silver halide, preferably 0.01 to 0.5 mol for the yellow coupler and 0.003 for the magenta coupler. In the cyan coupler, it is 0.002 to 0.3 mol.

The coating amount of the ultraviolet absorber may be an amount sufficient to impart light stability to the cyan dye image, but if used in an excessively large amount, it may cause yellowing in the unexposed portion (white background portion) of the color photographic light-sensitive material. Therefore, it is usually preferably in the range of 1 × 10 ⁻⁴ mol / m ² to 2 × 10 ⁻³ mol / m ² , and particularly 5 × 10 ⁻⁴ mol / m ^{2 to} 1.5 × 10 ⁻³ mol / m ² . Is set.

Light-sensitive material c Light-sensitive material that is the same as light-sensitive material a except that all the solvents of the first, third, and fifth layers of light-sensitive material a are replaced with comparative compound A. Light-sensitive material d Light-sensitive material d First, third, fifth layers of light-sensitive material c The same light-sensitive material as the light-sensitive material c except that the average particle size of the emulsified dispersion was changed as shown in Table 2 by adjusting the emulsification conditions in Example 1.

Experiments of treatments A and B were carried out.

The process consists of color development, bleach-fixing and washing with water.
The development time was changed to 1 minute, 2 minutes, and 3 minutes to evaluate the photographic properties. The contents of the processings A and B represent the difference between the color developing solutions A and B, and the other processings are the same in both A and B.

The evaluation of photographic properties was carried out on four items: relative sensitivity, gradation, maximum density (Dmax), and minimum density (Dmin).

The relative sensitivity is a relative value with the sensitivity when the color development time is 2 minutes in the processing A of each photosensitive layer of each photosensitive material being 100. The sensitivity was expressed as the relative value of the reciprocal of the exposure amount required to give a density obtained by adding 0.5 to the minimum density.

The gradation is indicated by the density difference from the sensitivity point to the point where the logarithm of the exposure amount (logE) increases by 0.5.

The results are shown in Table 3.
