Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photosensitive material containing a novel coupler having a ballast group.

Color-forming light-sensitive materials are generally imaged by a coupling reaction between an oxidized aromatic-grade amine thread color oil and a color-forming compound generally called a coupler. The dyes produced by coupling KL are azomethine, indophenol, indoaniline, indamine, phenoxazine, phenazine, and KL, depending on the chemical structure of the coupler and developing agent.
c+tlf pigment.

In this system, a subtractive color scheme is usually used to produce a color image of yellow, magenta and cyan, which are complementary colors to a silver halide emulsion that is selectively sensitive to red, green and red, respectively. Forming couplers are used.

+7 compounds that can be used as these couplers! l
Regarding VC, a large number of (C) 1 and 6 Ci documents have been published.

Couplers that are suitable for use in yellow paint forming are acylacetanilides, representative examples of which are listed below.

There are also known compounds described in No. 233, which react with oxidation and color-developing agents in the same manner as couplers, but do not produce dyes. This persimmon compound releases photographic active agents such as image suppressants by competing with color image-forming agents in reaction with oxidized forms of color developing agents or as a result of coupling reactions. It is used to make photographic images more accurate. In the present invention, these compounds are regarded as couplers because their reaction with the oxidized form of a color developing agent is the same as that of a color image forming agent.

A method for adding a coupler such as the one mentioned above to a photographic emulsion layer is f! Although a 4-hour method has been devised, a method in which a lipophilic ballast group is introduced into the coupler molecule, dissolved in an organic solvent, and emulsified and dispersed to achieve zero thrust is useful. The following properties are necessary for a coupler having a monooleophilic ballast group in order to produce a color photosensitive dye with excellent photographic performance. That is, (]) The coupler and the coloring dye produced in the image should have high solubility in the high boiling point organic solvent (Ganibat 1) Bresil Phosphate) VC used for dispersing the coupler.

(2) High stability after dispersion in silver halide photographic emulsion;
In addition, a stable coating film is formed without precipitation of coupler crystals even after coating on a support and drying.

(31) Has excellent diffusion resistance and does not diffuse into other layers.

(4) The dyeing quality is good, the spectral absorption characteristics of the dyed base 4 are excellent, and the color, intensity, and fastness to light of the 71' dye image are not damaged.

(5) Good development and high yield using an intermittent deposition method from inexpensive raw materials.

The conventionally known couplers having a pallast group have some defects and do not fully satisfy the above-mentioned necessary properties. These couplers having a lipophilic pallast group have excellent stability, diffusion resistance, and
In terms of the spectral absorption characteristics, fastness of color images, and suitability for synthesis, dyes are superior to other types of couplers (for example, couplers that have acid groups and are added to the emulsion layer as a micellar aqueous solution). Although there are many, there are still many that are satisfactory in terms of color development. In high-temperature rapid processing, which has recently become popular, color development is particularly important, and insufficient color development becomes a serious problem. In order to compensate for this insufficient color development, in some cases, an organic solvent such as benzyl alcohol is added to the developer as a color development promoter. These organic solvents for promoting color development have several drawbacks. For example, during the imaging process, it is absorbed into the emulsion layer, reducing the amount of lubrication in the developer, resulting in a decline in color development.

(It is carried into the young egg white solution or bleach-fix solution, inhibiting desilvering and reducing pigment concentration.

It is highly desirable to reduce the amount of organic solvents used to promote color development.

The couplers shown in Q, which contain a ballast group having a p-hydroxyphenylenesulfonyl group or a p-hydroxyphenylenesulfinyl group at the end, are improved over conventional couplers in terms of color development. However, it is still not sufficient, and also has a lower sister point of low bath dissolution with respect to the organic solvent for coupler dispersion.
