Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel method for obtaining a color print by using a photographic light-sensitive material.

[0002]

2. Description of the Related Art In a method known as conventional color photography, a color photosensitive material for photographing (so-called color negative) is usually a layer for recording blue light to form a yellow image, and a layer for recording green light to form a magenta image. Including a layer for recording red light to form a cyan image,
During development, the developing agent is oxidized in the process of reducing the silver halide grains containing the latent image formed by exposure to silver, and the reaction between the oxidized product and the dye-donating coupler (coupling reaction) Form a dye image. Undeveloped silver halide and developed silver are removed in the bleach-fixing step following the development processing step, the resulting negative dye image is projected and exposed on a color print light-sensitive material, and the same development and bleaching is performed on the color print material. A fixing process is performed to obtain a color print. Further, the development of a digital photo printer in which image information on a color negative film is photoelectrically read to form a digital signal, and a photosensitive material such as color paper is scanned and exposed by a recording light modulated in accordance with the signal to produce a finished print is in progress. . Examples thereof are disclosed in Japanese Patent Laid-Open No. 7-
No. 15593, etc. The above method is premised on ordinary wet development, bleaching, and fixing processing, the processing steps are complicated, and waste liquid processing of each processing liquid is also required.

On the other hand, as a method for processing a photosensitive material using silver halide, a simple and quick method using heat development has been developed. As examples thereof, there are known products such as 3M Dry Silver, Fuji Photo Film Co., Ltd.'s Pictrograph and Pictrostat. However, these are black-and-white or color print materials, and conventionally, no photosensitive material for photographing by heat development has been known. Further, as a form of heat development, a method of performing heat development in the presence of a small amount of water is known, and for example, such an example is described in JP-B-2-51494. The image forming method described therein uses a dye-donating substance that is reducing with respect to a photosensitive silver halide and that reacts with the photosensitive silver halide by heating to release a diffusible dye. It is a product in which the dye released during development is transferred to an image receiving material and the transfer side is used as a color print. An image forming method using a non-diffusible compound that releases a diffusible dye corresponding to silver development or inversely corresponding to silver development is known, and examples of the compound are, for example, EP220,746.

No. 500,626, US Pat. No. 4,639,408. These are mainly used for transferring a diffusible dye to an image receiving material to obtain a print.

We have devised a new method of using a photothermographic material as a photographic material and obtaining a print on another material based on the information on the photothermographic material after heat development.
No. 34600 and No. 7-331512. This method does not include a step of positively removing residual silver halide and developed silver after obtaining a color image on the light-sensitive material by a heat development step. The image quality of the print obtained by this method is quite good, but it is preferable to obtain a more saturated image quality and to improve the storability of the image obtained on the light-sensitive material.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel method for obtaining a color print with high color saturation by using a photographic light-sensitive material which uses a simple processing method.

[0006]

The above object includes at least a light-sensitive silver halide, a binder and a dye-donor compound on a support, and the light-sensitive wavelength region and the dye-donor compound are released or formed. After imagewise exposure of a photosensitive member having at least three types of photosensitive layers having mutually different absorption wavelength regions of dyes, the maximum total coating film of the processing member containing at least a base and / or a base precursor on the photosensitive member and the support. Water corresponding to 0.1 to 1 times the weight obtained by subtracting the weight of the entire coating film from the weight of water corresponding to the swelling volume is applied to the photosensitive member or the processing member, and then the photosensitive member and the processing member are separated into a photosensitive layer. The processed layers are superposed so that they face each other, and heated at a temperature of 60 ° C to 100 ° C for 5 seconds to 120 seconds to form a color image of at least three colors on the photosensitive member, and immediately thereafter In the image forming method of peeling the member and the processing member, converting the image information into optical or electrical information to obtain color image information, and then obtaining a color image on another recording material, at the same time with the heat development, Alternatively, by providing an additional heat treatment step after thermal development,
It was achieved by an image forming method characterized by dissolving part or all of silver halide and / or developed silver remaining on the photosensitive member.

In the present invention, a light-sensitive material containing a dye-donor compound and a processing member containing a base and / or a base precursor, which are extremely stable in the absence of a base, are used and heated in the presence of a small amount of water. When developed and an image based on the non-diffusible dye is formed on the light-sensitive material, an image excellent in graininess and sharpness is obtained, and based on this image information, another recording material such as color paper or heat-developable color print material. It is based on the finding that when printed above, a very good color image is obtained. Further, since the light-sensitive material and the base are separated until development, rapid processing is possible while satisfying the high storability of the light-sensitive material required for the photographic material.

According to the research conducted by the present inventors, the image formed by heat development on the photosensitive member of the present invention is relatively stable without additional development stop treatment. When photoelectrically reading color image information while leaving the information of developed silver, unnecessary residual silver halide and light scattering by developed silver deteriorate the information, so the obtained image information is printed on a color print. It was found that when reproducing, it could not be read unless a sufficiently strong light source was used, and that noise was mixed at the time of reading, which deteriorates image quality such as sharpness and graininess. According to the study by the present inventors,
It is not necessary to remove the silver halide and developed silver remaining on the photosensitive member from the photosensitive member to the processing bath as in the bleach-fixing method using a processing solution of the prior art in which the processing steps are complicated from the photosensitive material. However, it has been clarified that a part or the whole may be melted and light scattering such as haze may be removed so as not to cause image quality deterioration during reading.

As a method of dissolving a part or all of the remaining silver halide and developed silver, a conventionally known bleach-fixing agent is allowed to act during the heat development or in an additional step after the heat development. It is possible. When a bleaching agent and / or a fixing agent are caused to act simultaneously with the heat development, a small amount of water used for the heat development rapidly dissolves a part or all of the silver halide and the developed silver.
When part or all of silver halide and developed silver are dissolved in an additional step after heat development, a conventionally known bleach-fixing agent is contained in the second processing member.
In this case, a solvent may be added in order to rapidly dissolve a part or all of the silver halide and the developed silver, and the solvent may be a small amount of water as in the heat development of the present invention. Further, a heat solvent or an auxiliary solvent which accelerates the dissolution of the bleach-fixing agent may be used.

The dye-donor compound used in the present invention includes a dye moiety in its own structure and is a non-diffusible compound capable of releasing or diffusing a diffusible dye in response to or against silver development. The dye-donor compounds described above can be used. At the same time as or after the release, part or all of the diffusible dye is removed from the light-sensitive material, and the image is obtained on the light-sensitive material by the residual coloring material after development. Color images can be negative or positive with respect to the subject depending on the type of silver halide (negative emulsion, positive emulsion) and the type of coloring material (negative mode, positive mode), but diffusive for negative emulsion and silver development. A positive film can be obtained by using a non-diffusible coloring material that releases a dye. The image obtained on the light-sensitive material by this method is relatively stable and can be stored as it is.

The light-sensitive member used in the present invention contains at least three light-sensitive layers in which the spectral sensitivity and the hue of the dye-donating compound are different from each other. Each photosensitive layer may be divided into a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities. The above-mentioned three types of photosensitive layers are preferably layers that are sensitive to any of blue light, green light, and red light. In general, the order of arrangement is from the support side to the red photosensitive layer, the green photosensitive layer, and the blue photosensitive layer.

In the present invention, the silver halide, the dye-donating compound and the color developing agent may be contained in the same layer, but if they are in a reactive state, they may be added separately in separate layers. For example, when the layer containing the color developing agent and the layer containing silver halide are formed as separate layers, the raw storability of the light-sensitive material can be improved. The relationship between the spectral sensitivity of each layer and the hue of the coupler is arbitrary, but when a cyan coupler is used for the red photosensitive layer, a magenta coupler is used for the green photosensitive layer, and a yellow coupler is used for the blue photosensitive layer, it is possible to directly add color to conventional color paper.

Embedded image

The photosensitive member 201 was cut and punched in the same manner as in Example 5 to photograph an image, and another photosensitive member 201 which was heat-treated on the processing member R-3 was prepared. Immediately after processing the photosensitive member of 1.
After the application of 0 cc / m ² , it was overlapped with the processing member F102 and heated from the back surface of the photosensitive member for 30 seconds by a heat drum at 65 ° C. When the processing member F102 was peeled off from the photosensitive member 201, a negative image was obtained on the photosensitive member. This is referred to as a processed photosensitive member 201C. Processed photosensitive members 201A and 20
Each image on 1C was read by a CCD line scanner (Topaz, manufactured by Rhinotype Hell), processed on a personal computer, and then output by a heat development printer (PICTROGRAPHY3000, manufactured by Fuji Photo Film Co., Ltd.). The print obtained from the processed photosensitive member 201A had a large amount of CCD noise at the time of reading and the image quality was inadequate, but the print obtained from the processed photosensitive member 201C of the present invention had a small amount of CCD noise and was processed. It was superior in color reproducibility and graininess to the print obtained from the completed photosensitive member 201A. The processed photosensitive member 201C is Dmi
The developed silver in n parts was bleached and the Dmin was lowered further than that of the processed photosensitive member 201B, so that a more saturated print was obtained.
