Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a color photosensitive material, and particularly to a color photosensitive material that can be used with two or more different light sources.

(Background Art) Silver halide color photosensitive materials have extremely high image quality and are used in many fields. On the other hand, with the recent advances in office automation, advances in professional imaging equipment, the advent of electronic still cameras, the spread of video and facsimiles, advances in computer graphics, the development of image sensors, and advances in digital processing technology for original pictures, etc. There is an increasing demand for obtaining color hard copies from image information converted into electrical signals. Conventional color photosensitive materials usually have blue, green, and red spectral dispersions, and color CRT (cathode) is used to obtain images using image information that has been converted into electrical signals on such color photosensitive materials. CRTs are not suitable for producing large-sized prints.

Furthermore, light emitting diodes (LEDs) and semiconductor lasers have been developed as optical writing heads that can produce large-sized prints. However, no optical writing head has been developed that efficiently emits blue light. Therefore, for example, when using a light emitting diode, near-infrared (
800nm), red (670nm), yellow (570nm)
It is necessary to expose a color photosensitive material that has three layers spectrally sensitized to near-infrared, red, and yellow using a light source that combines three light-emitting diodes (nm), and to record images with this configuration. The system was described in "Nikkei New Material" September 14, 1987 issue, pages 47-57, and some of it has been put into practical use. In addition, a system was developed in JP-A-61 in which a light source combining three semiconductor lasers emitting light at 880 nm, 820 nm, and 760 nm was used to record on a color photosensitive material having three photosensitive layers with spectral sensitivities for each wavelength. -13714
It is stated in No. 9. However, the color luminescent materials used in these conventional systems are e.g.
Those with three photosensitive layers, green and red, cannot be used for image reproduction using an optical writing head such as a light emitting diode or semiconductor laser, and three photosensitive layers with spectral enhancement in near-infrared, red, and yellow cannot be used. Color photosensitive materials with a 100% brightness cannot be used for photographing landscapes or recording visible light such as on ordinary color CRTs; their use is limited to image reproduction using a specific light source. (Problems to be Solved by the Invention) An object of the present invention is to provide a color photosensitive material that can be used with at least two different light sources. (Means for Solving the Problems) An object of the present invention is to provide a color light-sensitive material having at least three layers on a support containing a combination of at least a photolucent silver halide, a binder, and a dye-providing compound. At least one of the layers has spectral sensitivity peaks at at least two wavelengths separated by 5Q nm or more, and at least one of the spectral sensitivity peaks is 70 nm or more apart.
This was achieved using a color photosensitive material characterized by having a wavelength of 0 nm or more. The color photosensitive material of the present invention basically has three photosensitive layers each having a different color sensitivity on a support, and each photosensitive layer consists of a photosensitive silver halide, a binder, and a dye-donating layer. Contains a combination of compounds. Here, "containing in combination" means not only the embodiment in which the photosensitive silver halide and the dye-providing compound are added together with the binder in the same layer, but also the embodiment in which the photosensitive silver halide and the dye-providing compound are added together with the binder in a reactable state in separate layers. This is an expression that also includes the state of being. Each color-sensitive layer may also be divided into two or more layers having different sensitivities. In the present invention, at least one of these color-sensitive layers has two or more spectral sensitivities separated by 50 nm or more from each other,
and at least one of them has a spectral sensitization peak of 7
Set to 0 0 nm or more.

It is preferable to combine cyan dye-providing compounds. In addition, in each of these embodiments, when a colored dye-donating compound is used, as in B) of (a), (c), and (c) above, when a colored dye-donating compound is used, an emulsion layer containing a yellow dye-donating compound is provided on the side closest to the light source. It is preferable to provide an emulsion layer containing a cyan dye-providing compound on the farthest side. Furthermore, when using an uncolored dye-providing compound, it is preferable to provide a yellow filter layer on the emulsion layer closest to the exposure light source. In light-sensitive materials, as a method of exposing and recording an image, for example, a layer containing a yellow dye-providing compound produces an evening color, a layer containing a maze/ta dye-providing compound produces a green color, and a layer containing a cyan dye-providing compound produces a green color. When the layers are each spectrally sensitized to red color, the infrared sensitizing dye of the present invention of 7 oonm or more is further added to the layer containing the yellow dye-donating compound, and in the case of a next-sensitized material, the following applications are possible. is possible.

Image formation accelerators include accelerating redox reactions between silver salt oxidizing agents and reducing agents, accelerating reactions such as generation of dyes from dye-donating substances, decomposition of dyes, and release of diffusible dyes, and photosensitive material waste. Physicochemical functions include bases or base precursors, nucleophilic compounds, high-boiling organic solvents (oils), thermal solvents, surfactants, and silver. It is also classified as a compound that interacts with silver ions. However, these substance groups generally have complex a-ability and usually have some of the above-mentioned promoting effects. For details on these see U.S. Patent 4,67
No. 8,739, columns 38-40.

Examples of base precursors include salts of organic acids and bases that are decarboxylated by heat, compounds that release amines by intramolecular nucleophilic substitution reaction, Rossen rearrangement, or Beckmann rearrangement. Specific examples thereof are described in US Pat. No. 4,511,493, Japanese Patent Application Laid-open No. 62-65038, etc.

In a system in which thermal development and dye transfer are performed simultaneously in the presence of a small amount of water, it is preferable to include a base and/or a base precursor in the dye fixing element in order to improve the storage stability of the photosensitive element.

In addition to the above, combinations of poorly soluble metal compounds and compounds that can undergo complex formation reactions with metal ions constituting the poorly soluble metal compounds (referred to as complex-forming compounds), as described in European Patent Publication No. 210, f360, and special Kaisho 61-23245
Compounds that generate bases by electrolysis as described in No. 1 can also be used as base precursors. The former method is particularly effective. It is advantageous to add the poorly soluble metal compound and the complex-forming compound to the light-sensitive element and the dye-fixing element separately.

Various development stoppers can be used in the photosensitive element and/or dye fixing element of the present invention in order to always obtain a constant image despite fluctuations in processing temperature and processing time during development.

The development stopper referred to in 22 is a compound that immediately neutralizes the base or reacts with the base to lower the base concentration in the film and stop development after proper development, or a compound that interacts with silver salt to develop. It is a compound that suppresses

Specifically, acid precursors that release acids upon heating;
Examples include electrophilic compounds that undergo a substitution reaction with a coexisting base when heated, nitrogen-containing heterocyclic compounds, merkabuto compounds, and precursors thereof.

For more details, see JP-A No. 62-253159 (31) - (
It is described on page 32). As the support for the photosensitive element or dye-fixing element of the present invention, one that can withstand processing temperatures is used. Common examples include paper and synthetic polymers (films). Prefecturally, polyethylene tere-7 tallate, polycarbonate, polyvinyl chloride, polystyrene, polypropylene,
Polyimide, cellulose (e.g. triacetylcellulose) or films containing pigments such as titanium oxide, film synthetic paper made from polypropylene, synthetic resin pulp such as polyethylene, and natural pulp. Mixed paper, Yankee paper, baryta paper, coated paper (especially cast coated paper), metal, cloth, plastic, etc. are used.

These can be used alone, or can be used as a support laminated on one or both sides with a synthetic polymer such as polyethylene.

In addition, JP-A-62-253159 (29) to (3)
The supports described on page 1) can be used.

The surface of these supports may be coated with hydrophilic binder, alumina sol, a conductive metal oxide such as tin oxide, carpon plack or other antistatic agent.

Methods of exposing and recording images on a photosensitive element include, for example, directly photographing landscapes and people using a camera, exposing through reversal film or paper using a printer or enlarger, and copying machines. A method in which the original image is scanned and exposed through a slit etc. using an exposure device, etc., a method in which image information is transmitted via an electric signal to a light emitting diode, various lasers, etc., and exposed to light; a method in which image information is transmitted to a CRT, liquid crystal display, electroluminescence, etc. There are methods such as outputting to an image display device such as a display or plasma display and exposing it directly or through an optical system. Light sources for recording images on the photosensitive element include natural light, tungsten lamps, light emitting diodes, laser light sources, CRT light sources, etc., as mentioned above, such as U.S. Pat. No. 4,500.
, 6 2 6, column 56 of the light source.

It is also possible to perform image exposure using a wavelength conversion element that combines a nonlinear optical material and a coherent light source such as a laser beam. Here, nonlinear optical materials are materials that can exhibit nonlinearity between the polarization and electric field that appears when a strong optical electric field such as a laser beam is applied, such as lithium diopate, potassium dihydrogen phosphate ( KDP), lithium iodate, Baize4, etc., urea derivatives, nitro-7niline derivatives, such as 3-methyl-
Nitropyridine-N-oxide derivatives such as 4-nitrobilinone-N-oxide (POM), JP-A-61-5
The compounds described in No. 3462 and No. 62-210432 are preferably used. As the form of the wave conversion element, single crystal optical waveguide type, 77-iper type, etc. are known, and any of them are useful.

The above-mentioned image information includes image signals obtained from video cameras, electronic still cameras, etc., television signals represented by the Nippon Television Signal Standard (NTSC), and images obtained by dividing an original image into a large number of pixels using a scanner. signal, CG, C
Image signals created using a computer such as AD can be used.

The photosensitive element and/or the dye fixing element may have a conductive heating layer as a heating means for thermal development or diffusion transfer of the dye.

In this case, the transparent or opaque heating element is
Those described in Specification 8 of No. 1-145544 can be used. Note that these conductive layers also function as antistatic layers. The heating temperature in the heat development process can be from about 50°C to about 250°C, and is particularly useful at about 80°C to about 180°C. The dye diffusion transfer step may be performed simultaneously with the heat development, or may be performed after the heat development step is completed. In the latter case,
The heating temperature in the transfer step can be in the range from the temperature in the heat development step to room temperature, but is particularly preferably 50° C. or higher and up to about 10° C. lower than the temperature in the heat development step.

Dye migration can also be caused by heat alone, but a solvent may be used to promote dye migration.

Also, JP-A-59-218443, JP-A No. 61-2380
As detailed in No. 56, etc., a method in which development and transfer are performed simultaneously or continuously by heating in the presence of a small amount of solvent (particularly water) is also useful. In this method, the heating temperature is 5
The boiling temperature of the solvent is preferably 0° C. or higher and not higher than α. For example, when the solvent is water, the temperature is preferably 50° C. or higher and 100° C. or lower.

Examples of solvents used to accelerate development and/or transfer the diffusible dye to the dye fixing layer include water or basic aqueous solutions containing alkali metal salts or organic bases (these bases include Those described in the section of image formation accelerators can be used. Furthermore, a low boiling point solvent or a mixed solution of a low boiling point solvent and water or a basic aqueous solution can also be used. Further, a surfactant, an antifoggant, a complex-forming compound with a sparingly soluble metal salt, etc. may be included in the solvent.

These solvents can be used in a method in which they are applied to the dye fixing element, the photosensitive element, or both.

The amount used can be as small as less than the weight of the solvent corresponding to the maximum swelling volume of the entire coating (particularly less than the weight of the solvent corresponding to the maximum swelling volume of the entire coating minus the weight of the entire coating). .

As a method for applying a solvent to the photosensitive layer or the dye fixing layer, there is, for example, the method described in JP-A-61-147244, page (26). It is also possible to use the solvent by preliminarily incorporating it into the photosensitive element, the dye fixing element, or both, such as by encapsulating the solvent in microcapsules. Further, in order to promote dye transfer, a method may be adopted in which a hydrophilic thermal solvent that is solid at room temperature and dissolves at high temperature is incorporated into the photosensitive element or dye fixing element. The hydrophilic thermal solvent may be incorporated into either the photosensitive element or the dye fixing element, and may be incorporated into both. ! - You can let it. Further, the layer to be incorporated may be an emulsion layer, an intermediate layer, a protective layer, or a dye fixing layer, but it is preferably incorporated in the dye fixing layer and/or a layer adjacent thereto. Examples of hydrophilic heat solvents include ureas, pyridines, amides, sulfonamides, imides, alnyls, oximes, and other heterocycles.

Further, in order to promote dye transfer, a high boiling point organic solvent may be contained in the photosensitive element and/or the dye fixing element.

Heating methods in the development and/or transfer process include contact with a heated block or plate, contact with a hot plate, hot presser, heated roller halogen lamp heater, infrared and far infrared lamp heater, etc. For example, it may be passed through an atmosphere of
