Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to a color photographic element comprising a development accelerator coupler in a development promoting concentration.
Color photographic images in color photographic materials are usually formed by the reaction between an oxidized silver halide developing agent and a dye-forming compound commonly referred to as a coupler. This reaction mode is well known in the photographic art. Such color photographic materials used in the photographic art also include a light sensitive silver halide emulsion layer.

[0002]

2. Description of the Related Art Typical color photographic materials are, for example, US Pat. Nos. 4,980,267 and 4,982,9.
96, as well as EP 193,389. However, these patent specifications do not disclose means for reducing the silver halide concentration of color photographic silver halide materials, especially the magenta layer of such materials.

[0003]

A difficult problem with photographic silver halide is the need to reduce the concentration of silver required to provide a developed image. Prior attempts to reduce the concentration of photographic silver halide have been completely unsuccessful.

[0004]

The present invention is directed to pyrazolo [3,2-c] -1,2,4-triazole, pyrazolo [1,5-b] -1,2,4-triazole and 1,
It contains at least one magenta image dye-forming coupler selected from 2,4-anilino-5-pyrazolone and has the formula —S—R ⁸ —R ⁹ (wherein R ⁸ is alkylene having 1 to ⁸ carbon atoms). And R ⁹ is a water solubilizing group) and a development accelerator coupler containing a coupling-off group (A) represented by an amount sufficient to promote development (showing a bleach-accelerating effect upon exposure and processing of the photographic element). The use of a color photographic element comprising a support bearing at least one photographic silver halide emulsion layer comprising a non-concentrated) allows reduction of silver concentration as described above.

The amount of development accelerator coupler significantly reduces the concentration of image dye-forming coupler required to form photographic silver halide and / or exposure and processing of useful color images, especially magenta images, of color photographic elements. Such a development-accelerating concentration. The concentration of photographic silver halide can be reduced to at least 5% by weight, measured as silver ions, and sometimes its concentration can be reduced to at least 13% to 25% by weight.

Also, the image dye-forming coupler concentration can be reduced to at least 5% by weight, preferably 23 to 37% by weight. It is recognized that both the silver halide and the image dye-forming coupler can be reduced, thus providing the most useful color image.

[0007]

Specific Embodiment A magenta image dye-forming coupler is
Pyrazolo [3,2-c] -1,2,4-triazole,
It can be selected from pyrazolo [1,5-b] -1,2,4-triazole and anilino-5-pyrazolone.

loss, Section XVIII, exposure to actinic radiation, typically in the visible region of the spectrum to form a latent image, followed by Research Disc.
A visible image is formed by processing as described in section XIX. Processing to form a visible image includes the step of contacting the element with a color developing agent to reduce developable silver halide and oxidize the color developing agent. Oxidized color developing agent in turn reacts with the coupler to give the dye.

With negative-working silver halide, the processing step described above provides a negative image. To obtain a positive (or reversal) image, this step is followed by development with a non-color developing agent to develop the exposed silver halide (no dye formation) and then to uniformly fog the element. Makes exposed silver halide developable. Direct positive emulsions may also be used to obtain a positive image.

After development, the silver and silver halide are removed by conventional steps of bleaching, fixing or bleach-fixing, followed by washing and drying.

Claims (2)

[Claims] 1. A color photographic element comprising a support bearing at least one photographic silver halide emulsion layer containing at least one magenta image dye-forming coupler comprising: a) said magenta image dye-forming. The coupler is at least one of the group consisting of pyrazolo [3,2-c] -1,2,4-triazole, pyrazolo [1,5-b] -1,2,4-triazole and anilino-5-pyrazolone. And b) said emulsion layer contains a development accelerator coupler in an amount sufficient to accelerate development, said development accelerator coupler being of the formula —S—R ⁸ —
A coupling accelerator (A) represented by R ⁹ (wherein R ⁸ is an alkylene group having 1 to ⁸ carbon atoms, and R ⁹ is a water-solubilizing group), and a development accelerator A color photographic element characterized in that said concentration of coupler has no bleach-accelerating effect upon exposure and processing of said photographic element. 2. At least one red-sensitive photographic halide wherein the support comprises in sequence a cyan image dye-forming phenolic coupler, a bleach activator-releasing coupler and at least one development inhibitor-releasing coupler. At least one magenta image dye-forming pyrazolo [3,2-c] -1,2,4-triazole coupler carrying a silver emulsion layer and at least one development inhibitor releasing coupler of the formula: Chemical 1] 0.25 to 33 mg / m ^{2 of the} development accelerating coupler represented by
At least one green-sensitive photographic silver halide layer comprising a development-accelerating concentration of, a yellow filter layer, and at least one pivalyl acetanilide yellow image dye-forming coupler, and at least one At least one blue-sensitive photographic silver halide emulsion layer comprising an alkoxyphenyl acetanilide yellow image dye-forming coupler, at least one development inhibitor releasing coupler and at least one development accelerating coupler. The color photographic element of claim 1 which comprises a support.
