The forms of the periodic ruggedness observed from front side can be optional, but it is preferred to have circular, elliptical, square, rectangular, rhombic, pentagonal, and hexagonal forms, and a combination of any of them, and the depth of ruggedness is, preferably, 0.1-20mum, still preferably, 0.2-10mum, and especially, 0.3-5mum, expressed by the peak to peak value, thus permitting the obtained photographic sensitive material to be remarkably reduced in unevenness of color development density.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reflective silver halide color photographic material, and more particularly to a silver halide color photographic material with improved color unevenness and density unevenness.

(Prior Art) Supports used for photographic light-sensitive materials are usually synthetic resin films such as triacetylacetate, polyethylene terephthalate, and vinyl chloride, paper, and paper supports laminated with synthetic resin on both sides. However, it is known that minute irregularities existing on the surface of these supports often cause unnecessary color unevenness and density unevenness in developed images. Furthermore, these unevenness occur in color photographic materials that have a large number of coated layers, reflective materials that observe density using reflected light, and photosensitive materials that form a positive image without passing through a negative photosensitive material (reversal paper). , autopositive paper, silver dye bleaching method, etc.).

(Problems to be Solved by the Invention) Solutions to the above problems include improving the smoothness (flatness) of the support as much as possible, or applying a thick undercoat layer before applying the photosensitive layer. Although attempts have been made to smooth the surface, there are still problems such as technical difficulties and increased manufacturing costs, and no satisfactory solution has yet been found.

Accordingly, an object of the present invention is to provide a reflective silver halide color photographic material in which color unevenness and density unevenness in images are reduced.

(Means for Solving the Problems) The object of the present invention is to provide a photographic light-sensitive material containing at least three silver halide emulsion layers having different color sensitivities on a reflective support. The surface is ≠～,
A silver halide color photographic light-sensitive material having periodic irregularities of 20/fi was achieved.

The present invention will be explained in detail below.

As a result of various sensory tests, it was found that the color unevenness and density unevenness are visually more noticeable when unevenness with a length of 0.2 tm to jm is arranged irregularly on the surface of the reflective support. Therefore, in order to make the unevenness less noticeable, it is better to make the unevenness 18 or more or less than O0λ, reduce the component of 0.2 to jm, or arrange it regularly. Specifically, it is necessary to provide periodic irregularities of V to 20 pieces/N on the surface of the support.

In the present invention, the period of the above y regular unevenness is jm1
More preferably, it is 0/dragon.

The shape observed from the periodically uneven surface may be any shape, but preferably circular, round, triangular, square, rectangular, bi-shaped, pentagonal, and hexagonal.

Furthermore, a combination of these may be used. It may also be a combination of items of different sizes, but the size ratio is /
:/ to l:λQ is desirable.

Further, the periodicity as used in the present invention only needs to be in a certain direction on the surface of the support, and it is not necessary to have periodicity in other directions.

Preferably, it has a period of ≠ to 20 in the direction perpendicular to the direction in which the concavities and convexities have a period according to the present invention.

The depth of periodic irregularities is 0.11 at peak to peak value.
The thickness is preferably 1 m to 10 μm. More preferably 0.2
μm to ioμm, more preferably 0.3μm
The thickness is between 3 μm and 3 μm.

A common method for forming irregularities on the support is to press a molded roller against the support when forming the support. The molded roller may be a cooling roller that cools the heated support, or may be a heating roller.

The unevenness of the support can be measured using, for example, [Profile Analyzer J (
PROFILE ANALIZER) (SE-3F)
It can be measured with [manufactured by Koita Research Institute].

The effects of the present invention can be obtained using a reflective support made of any material.

Preferred materials include baryta paper, laminated paper, white pigment-containing polyethylene terephthalate paper, vinyl chloride sheet, and the like. Particularly desirable are paper supports for which it is difficult to obtain a smooth support during manufacture, and supports made by laminating paper with resin.

It is highly effective when applied to reflective color photographic materials (layers or more). Applicable photosensitive materials include color paper, direct positive color paper, reversal color paper, silver dye bleaching type color paper, heat developable color paper, diffusion transfer type paper, and the like. The effects of the present invention are particularly noticeable in direct positive color paper, reversal color paper, silver dye bleaching color paper, and the like.

In order to remove soluble silver salts from the emulsion before and after physical ripening, Nudel water washing, flocculation sedimentation method, ultrafiltration method, etc. are used.

The emulsion used in the present invention is usually one that has been subjected to physical ripening, chemical ripening and spectral sensitization. Additives used in such processes are described in the aforementioned Research Disclosure A/7A4tj (December 1971) and Research Disclosure A/7A4tj (December 1971) and Research Disclosure A/7A4tj (December 1971),

The turnip treatment of the present invention is carried out by the "light fogging method" and/or the "chemical fogging method" described below. The entire surface exposure in the "Moto Kabushi method" of the present invention, that is, the Kabushi 91M light is performed after the imagewise exposure and/or during the development process.

The image-wise light-sensitive material is immersed in a developer or a pre-bath of the developer, or is taken out of these solutions and exposed before it dries, but it is most preferable to expose it in the developer. .

As the light source for the overexposure, any light source within the wavelength range to which the photosensitive material is sensitive may be used, and generally any of fluorescent lamps, tungsten lamps, xenon lamps, sunlight, etc. can be used.

Photosensitive materials that are sensitive to all wavelengths, such as color photosensitive materials, are disclosed in JP-A No. 6-/37JJO and the same! r-70.
A light source with high color rendering properties (as close to white as possible) as described in No. 223 is preferable. The illuminance of the light is o, oi ~ 20
00mil 2000 lux.

It is preferable to immerse the light-sensitive material in a developer solution or a pre-bath solution, and to irradiate the light-sensitive material after the solution has sufficiently penetrated into the emulsion layer of the light-sensitive material. The time from penetration into the liquid to light exposure is generally λ seconds to λ minutes.

Exposure times for turnips are generally o,oi seconds to λ minutes.

In the present invention, the nucleating agent used when applying the so-called "chemical Kabu9 method" can be contained in the light-sensitive material or in the processing solution for the light-sensitive material. Preferably, it can be incorporated into the photosensitive material.

Here, the "nucleating agent" is a substance that acts to directly form a positive image during surface development of an internal latent image type silver halide emulsion that has not been fogged in advance. In the present invention, it is particularly preferable to perform a turnip treatment using a nucleating agent.

When the nucleating agent is added to a light-sensitive material, it is preferably added to the latent type silver rhodide emulsion layer, but as long as the nucleating agent is adsorbed to the silver rhodide by diffusing during coating or processing. It may also be added to other layers such as intermediate layers, undercoat layers and back layers.

When the nucleating agent is added to the processing solution, it may be contained in the developer solution or a low pH prebath as described in JP-A-31-171310.

Furthermore, two or more types of nucleating agents may be used in combination.

The photosensitive material of the present invention includes a cross-agent for preventing irradiation and halation, an ultraviolet absorber, a plasticizer, a fluorescent whitening agent, a matting agent, an air capping agent, a coating aid, a hardening agent, and an antistatic agent. It is possible to add additives such as additives and slip property improvers. Typical examples of these additives are Research Disclosure magazine A/7 Jpi 3■~X■ (/7 published in 1972) p. 1/month) pAlfi7~≦j/.

The color photographic material according to the present invention includes the above-mentioned RD,
A/ 7 A 4' jノJ 1r-29fi, and U
It can be developed by the usual method described in 61/left column to right column of MA/17/lh.

The color developing solution used in the development of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent as a main component. As this color developing agent, amine phenol compounds are also useful, but p-phinidine diamine compounds are preferably used, and typical examples thereof include 3-methylderabanor-N, N-diethylaniline, 3-diethylaniline, Methyl-≠-amino-N-ethyl-N
-β-hydroxyethylaniline, 3-methyl-Hiro-amino-N-ethyl-N-β-methanesulfonamidoethylaniline/, 3-methyl-Hiro-amino-N-ethyl-N
-β-methoxyethylaniline and their sulfates, hydrochlorides, p-toluenesulfonates, and the like. Two or more of these compounds can be used in combination depending on the purpose.

The color developing solution contains pH buffering agents such as alkali metal carbonates, borates or phosphates, bromide salts, iodide salts,
Development inhibitors or antifoggants such as pe/dimidazoles, benzothiazoles or mercapto compounds are typically included. Also, if necessary, hydroxylamine, diethylhydroxylamine, sulfite hydrazines, phenyl semicarbazides, triethanolamine, catechol sulfonic acids, etc.)! J ethylenediamine (/, 44-diazabicyclo[λ.

λ, co]octane), organic solvents such as ethylene glycol and diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, and amines, dye-forming couplers, Competitive couplers: fogging agents such as sodium boron hydride, auxiliary developing agents such as l-phenyl-3-pyrazolidone, tackifiers, aminopolycarboxylic acids,
Typical examples include various chelating agents such as aminopolyphosphonic acid, alkylphosphonic acid, and phosphonocarboxylic acid, and salts thereof.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. This black and white developer contains known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as l-phenyl-3-pyrazolidone, or amine phenols such as N-methyl-p-aminephenol. Alternatively, they can be used in combination.

The pH of these color developing solutions and black and white developing solutions is generally in the range of -l. Also, the compensation t of these developers
Although it depends on the color photographic light-sensitive material being processed, it is generally less than 31 h per 7 square meters of light-sensitive material, and by reducing the bromide ion concentration in the brightening solution, ptoo
−Can also be less than or equal to: When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank. Furthermore, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developer.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process (bleach-fixing process) or separately. Furthermore, in order to speed up the processing, a processing method may be used in which a bleaching treatment is followed by a bleaching treatment. Furthermore, treatment with two consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment can be carried out as desired depending on the purpose. As a bleaching agent, for example, iron (■), copal) (In
), compounds of polyvalent metals such as chromium (Vl), copper (II), peracids, quinones, nitro compounds, etc. are used.

Bleach accelerators may be used in bleaching solutions, bleach-fixing solutions, and their pre-baths, if necessary.

Examples of fixing agents include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used, with ammonium thiosulfate being the most widely used. Can be used for As the preservative for the bleach-fix solution, sulfites, bisulfites, or carbonyl bisulfite adducts are preferred.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to water washing and/or stabilization steps after desilvering treatment.

The amount of water and washing water in the washing process depends on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the coating, the washing water temperature, the number of washing tanks (number of stages), the replenishment method such as free flow, down flow, etc., and various other factors. It can be set over a wide range depending on the conditions. this house,
The relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is J

It can be determined by the method described in λj3 (/ri!!, 2016 issue).

The pH of the washing water in the processing of the photosensitive material of the present invention is ≠-
preferably z-r. The washing water temperature and washing time can be set in various ways depending on the characteristics of the photosensitive material, its use, etc., but in general, it is /j-4Lj 0 seconds-0 minutes at 0C, preferably 30 seconds-0 minutes at λj-≠o'C. ! A range of minutes is selected. Furthermore, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water. This kind of stabilization treatment is described in JP-A-17-R,! 4! No. 3, rr
-7 Hiromu, r3μ issue, 60-220. All known methods described in No. Jvj can be used.

Further, following the water washing treatment, a further stabilization treatment may be carried out, such as a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photosensitive materials for photography. .

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The overflow liquid from water washing and/or replenishment of the stabilizing liquid can be reused in other processes such as the desilvering process.

Various processing solutions in the present invention are used at io 0 cmjo°C. Normally, temperatures of 336C to Jr'C are standard, but higher temperatures can be used to accelerate processing and shorten processing time, while lower temperatures can be used to improve image quality and stabilize the processing solution. Improvements can be achieved.
