Abstract

PURPOSE:To form the photosensitive material with a smaller film thickness and to enhance the flatness and sharpness thereof by specifying the thickness of a base, the content of a hydrophilic binder on the emulsion layer side and the average oil drop density of the entire layer on the emulsion layer side. CONSTITUTION:This photosensitive material is constituted by forming >=1 layers of the silver halide emulsion layers on the base (e.g.: polyester film), specifying the thickness of the base to 50 to 100 mum, and the total weight per unit area of the hydrophilic binder (e.g.: gelatin) of the total hydrophilic colloidal layer on the emulsion side to 5.0 to 20.0 g/m<2>. Further, the average oil drop density of the total layer on the emulsion layer side is specified from 0.2 to 0.7. The flatness is no longer maintained if the oil drop density is below the above- mentioned range. The strength of the emulsion film weakens and such is undesirable if the density exceeds the above-mentioned range.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a light-sensitive material that is smaller in size and thinner.

(Prior Art) In recent years, with remarkable progress in silver halide color photographic materials and cameras, it has become possible to obtain high-quality photographs using 33 mm roll film.

However, cameras using 33wH'H roll film have a disadvantage of poor portability due to their large volume and heavy weight. In order to improve portability,
2. Description of the Related Art Small cameras such as /10 (so-called pocket) size cameras and disk cameras have been proposed and developed. However, as these cameras became more compact, the effective area of the exposure screen also became smaller, resulting in a deterioration in image quality, which was not well received by users.

Therefore, without reducing the exposure image area, camera 2f,
In order to downsize, it is important to downsize a three-layer, mm-sized film cartridge.

One of the major factors that determines the volume of this cartridge is the film thickness of the photosensitive material, and if it becomes possible to make the film thinner of this photosensitive material, especially the support that occupies most of the film, the cartridge will become smaller. can be achieved. However, simply making the support of the conventional 33mm photographic photosensitive material a thin film makes it difficult to maintain the flatness of the photosensitive material when pressing the button in the camera and when printing on photographic paper after developing the photographic photosensitive material. There was a problem that blurring occurred and image quality, especially sharpness, deteriorated. In addition, when so-called rapid processing and rapid drying, which has recently become popular, the photosensitive material may partially bend slightly during drying. It has also become clear that the sharpness after printing is deteriorated.

(Problems to be Solved by the Invention) Seventh, the purpose of the present invention is to provide a thinner silver halide color photographic material for use in compact and portable cameras; and 7971, it is an object of the present invention to provide a photosensitive material in which the material maintains good flatness and has less deterioration in sharpness due to defocusing;
Thirdly, it is necessary to provide a photosensitive material that does not produce minute bends before and after drying during development, and thirdly, it is necessary to provide a photosensitive material that has strong film strength, is a thin film, and has excellent sharpness. The third objective is to provide a photosensitive material with high sensitivity, excellent sharpness, and strong film strength.

(Means for Solving the Problems) These objects of the present invention have been achieved by the following photosensitive materials.

In a silver halide color photographic light-sensitive material having at least seven silver halide emulsion layers on a transparent support, the thickness of the transparent support is 50 μm or more/θ0 μm or less, and the total hydrophilic colloid layer on the emulsion layer side is The total weight per unit area of the hydrophilic binder! , 017m or more +20.0
? /m2 or less, and the average oil droplet density of the entire layer on the emulsion layer side is 0.7 or more and 0.7 or less.

The present invention will be explained in detail below.

According to the present invention, the transparent support has a thickness of 50 μm or more and 100 μm
Must be less than or equal to, but preferably! ! The thickness is preferably from 60 to 0 μm, more preferably from 60 to 0 μm.

Useful as flexible supports are, for example, cellulose esters (especially cellulose triacetate, cellulose diacetate, cellulose propionate, cellulose acetate propionate, cellulose butyrate, cellulose acetate phthalate), polyamides, polycarbonates, polyesters. (Aromatic dicarbonates such as polyethylene terephthalate, poly/, 4t-cyclohexane dimethylene terephthalate, polyethylene/8,2-dieenoxyethane, l'-dicarboxylate, polybutylene terephthalate, polyethylene naphthalate metal sulfonates) Copolymerized polyester with acid as copolymerization component, copolymerized polyester with metal sulfonate-containing aromatic dicarboxylic acid and aliphatic dicarboxylic acid as copolymerization component), polystyrene/, polypropylene, polyethylene, polymethylpentene, polysulfone, polyester Films made of semi-gross or platform polymers such as ether sulfone, polyarylate, aromatic polyetherimide, aromatic polyamide, aromatic polyamideimide, polyphenylene sulfide and the like are mentioned.

These supports contain a plasticizer for the purpose of imparting flexibility, etc. - May be used as an additive. In particular, cellulose esters containing plasticizers such as phenyl phosphate, binenyl phosphate, and dimethylethyl heptophosphate are commonly used. The thickness of the support is preferably 700μ or less for the purpose of the present invention). The case of θμ to 50μ is more preferable, and the case of ♂Oμ to 20μ is particularly preferable.

Support strength is breaking strength aH/mm2 or more, initial elastic modulus/! 0147mtn2 or more, flexural modulus/! okgim
m or more is preferred.

The molecular weight of these support polymers can be 70,000 or more, but those having a molecular weight of 20,000 to 50,000 are usually used.

When these polymers are used as supports, since all of the supports have hydrophobic surfaces, photographic layers (for example, photosensitive silver halide emulsion layers, photosensitive silver halide emulsion layers, It is extremely difficult to firmly bond the intermediate layer, filter layer, etc. A conventional technique attempted to overcome these difficulties is A.
- (1) Surface activation treatments such as chemical treatment, mechanical treatment, corona discharge treatment, flame treatment, ultraviolet treatment, high frequency treatment, glow discharge treatment, activated plasma treatment, laser treatment, mixed acid treatment, ozone oxidation treatment, etc. (2) - After these surface treatments have been performed, or without surface treatment, an undercoat layer is provided and a photographic emulsion layer is applied on top of the undercoat layer. There are three methods. (For example, U.S. Patent No. !, 4jP

-φJ/, 2, Tokko Akira! /-Gugu6 etc.). All of these surface treatments seem to be due to the creation of more or less polar groups on the surface of the support, which was originally hydrophobic, and by increasing the crosslinking density on the surface, and as a result, the undercoating It is thought that the affinity with the polar groups of the components contained in the liquid increases, or that the fastness of the adhesive side increases. Also, various ideas have been made for the structure of the undercoat layer. A layer that adheres well to the support (hereinafter referred to as the first undercoat layer) is provided as the seventh layer, and a photographic layer is placed on top of it as the second layer. A hydrophilic resin layer that adheres well to the layer (hereinafter referred to as undercoat layer, 27g1
There are two methods: a so-called multi-layer method in which a resin layer (hereinafter referred to as "resin layer") is coated, and a single-layer method in which only one resin layer containing both a hydrophobic group and a hydrophilic group is coated.

Among the surface treatments in (1), corona discharge treatment is of course popular, but any conventionally known method may be used, such as Tokko Shogu♂-, tO←No. 3, Tokko Shoso 7-j/Ri0# , Japanese Patent Publication No. 117-. No. 21067, Japanese Patent Application Publication No. 137

If the pressure is too low, the surface treatment effect will decrease, and if the pressure is too high, an excessive current will flow, easily causing sparks, which can be dangerous (7. There is a risk of destroying the object to be treated. Discharge is carried out in a vacuum tank. It is generated by applying a high voltage between metal plates or metal rods arranged vertically in/in a space of two or more.This voltage can take various values depending on the composition and pressure of the atmospheric gas. However, normally within the above pressure range, a stable steady glow discharge occurs between J'oo-tooooV.A particularly suitable voltage range for improving adhesion is 5ooo-aoooV.

Regarding the layer, the properties of gelatin have been mainly studied.

In the single layer method, good N contact properties are often obtained by utilizing interfacial mixing of the support and the undercoating polymer, and it is often used for cellulose derivative supports.

Surface treatment has little effect on cellulose derivatives;

The fine oil droplets of the present invention refer to droplet particles that are finely dispersed in an oil-like independent system in a binder consisting essentially of a hydrophilic colloid substance and are substantially insoluble in water.

The size of normal oil droplets is 0.03~01Jμm,
The size of the matting agent added to prevent adhesion to the surface of the sensitive material is usually 0.3 to 78 m.

In the present invention, the average oil droplet density of the whole layer must be 0.2 to 0.7, but particularly preferably 0.33 to Q. ! It is. If it is more than this, the emulsion film strength will be weak, and if it is less than this, the flatness of the photosensitive material cannot be maintained.

According to an aspect of the present invention, the flatness of the photosensitive material can be maintained even when using a thin support, but this depends on the tensile strength of the support, the tensile strength of the emulsion film, and the film thickness of the support. It is presumed that this is because the amount of hydrophilic binder contained in the emulsion film varies within the range of the present invention.

Therefore, the tensile modulus (initial apparent Young's modulus) of the support suitable for the emulsion layer having the total layer average oil droplet density and the total weight per unit area of the hydrophilic binder of the present invention is 2o

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. Aminophenol compounds are also useful as color developing agents, but p-phenylenediamine compounds are preferably used, representative examples of which are 3-methyl-≠-amino-N, N-diethylaniline, 3- Methyl-ψ-amino-N-ethyl-N-
iso-β-hydroquine ethylaniline, 3-methyl-≠-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-l-ami/-N-:r-f-β-methoxyethylaniline Examples include sulfates, hydrochlorides, p-)luenesulfonates, and the like. Among these, 3-meF-ru≠-amino-N-ethyl-Nβ-hydroxyethylaniline sulfate is particularly preferred.

Two or more of these compounds can be used in combination depending on the purpose.

The color developing solution may contain alkali metal carbonates, borates, or phosphates, (pH buffering agents, chloride salts, bromide salts, iodide salts, benzimidazoles, benzothiazoles, or It generally contains a development inhibitor such as a mercapto compound or an antifoggant.Hydroxylamine, diethylhydrokylamine, sulfite, N,N-biscarboxylene methylhydrazine, etc. are generally included. Various preservatives such as hydrazines such as phenyl semicarbazides, triethanolamine, catechol sulfonic acids, organic solvents such as ethylene glycol and diethylene glycol, developing agents such as benzyl alcohol, polyethylene glycol, 4M ammonium salts, and amines. Accelerators, dye-forming couplers, competitive couplers, auxiliary developing agents such as l-phenyl-3-pyrazolidone, tackifiers, aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, phosphonocarboxylic acids. Various chelating agents such as

, N-tetramethylenephosphonic acid, ethylene glycol (0-hydroxyphenylacetic 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 dihydrox-7benzenes such as hydroquinone, 3-pyrazolidones such as /-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol nato. It can be used alone or in combination.

The pH of these color developing solutions and black and white developing solutions is generally 2 to 2/2. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material to be processed, but it is generally less than 31 per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher, it can be increased to 600 or less.
It can also be less than m1. 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.

The contact area between the photographic processing solution and air in the processing tank can be expressed by the aperture ratio defined below.

That is, one seven! r3- The above aperture ratio is 0. It is preferably less than /, and more preferably 0.00/~o, o. As a method for reducing the aperture ratio in this way, in addition to providing a shield such as a floating lid on the surface of the photographic processing solution in the processing tank, there are also methods for reducing the aperture ratio.
Examples include a method using a movable lid described in No. '2033, and a slit development method described in JP-A No. 63-2/6060. Reducing the aperture ratio is
It is preferable to apply it not only to both color development and black-and-white development steps, but also to all subsequent steps, such as bleaching, bleach-fixing, fixing, washing, and stabilization. Also,
The total amount of replenishment can also be reduced by using means to suppress the accumulation of bromide ions in the developer.

The color development process usually takes 2~! The processing time can be further shortened by using a high temperature, high pn, and a high concentration of color developing agent.

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

Bleaching treatment may be carried out at the same time as fixing treatment.
- (Bleach-fixing treatment) may be carried out separately. Furthermore, in order to speed up the processing, a processing method may be used in which bleaching is followed by bleach-fixing. 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 the bleaching agent, for example, compounds of polyvalent metals such as iron (III), peracids, quinones, nitro compounds, etc. are used. Typical bleaching agents include organic complex salts of iron ([1), measured as ethylenediaminetetraacetic acid, diethylenetriane (rF-1m), cyclohexanediaminetetraacetic acid, methyliminodicoxic acid, /, 3-diaminopropanetetraacetic acid, and glycol ether. Aminopolycarboxylic acids such as diaminetetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc. can be used. Among these, ethylenediaminetetraacetic acid iron (Ill) complex salts, and 7.3-
Aminopolycarboxylic acid iron (III) complex salts, such as diaminopropane ferric acid (III) complex salts, are preferred from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, it is particularly useful in aminopolycarboxylic acid iron (m) complex salts il'i bleach solutions and bleach-fix solutions. The pH of the bleaching solution or bleach-fixing solution using these aminopolycarboxylic acid iron (III) complex salts is usually p, o-y, but the pH can be lowered to speed up the processing.

A bleach accelerator may be used in the bleaching solution, bleach-fixing solution, and their prebaths, if necessary.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used. Among them, ammonium thiosulfate is the most widely used. Further, a combination of thiosulfate, thiocyanate, thioether compound, thiourea, etc. is also preferred. As the preservative for the fixing solution and bleach-fixing solution, sulfites, bisulfites, carbonyl sulfite adducts, or sulfine enemy compounds described in European Special Law No. ZP+74FA are preferred. Furthermore, it is preferable to add various aminopolycarbonates and organic phosphones to the fixer and bleach constant N'e for the purpose of stabilizing the solution. The total time of the desilvering process is preferably as short as possible without causing desilvering defects. A preferable viewing time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes. The treatment temperature is preferably 2'C - 5oC, 1 - 4T'C for 3 nights. In a favorable temperature range, the desilvering rate improves,
In addition, the occurrence of staining after processing is effectively prevented.

In the derailment step, it is preferable that the stirring be as strong as possible. As a specific method for strengthening stirring, please refer to Japanese Patent Application Laid-Open No. 1973-1999-/! '3≠to issue, same tλ-/13g&/
A method of impinging a jet of processing liquid on the emulsion surface of a photosensitive material as described in JP-A-621-3-61, a method of increasing the stirring effect by using the sound of a rotating means, and a wiper installed in the liquid. Examples include a method in which the light-sensitive material is moved while the grade and the emulsion surface are in contact with each other to create turbulent flow on the emulsion surface, thereby improving the stirring effect, and a method in which the circulation flow rate of the entire processing liquid is increased. Such means for improving agitation is effective for any of the bleaching solution, bleaching solution, and fixing solution.

It is believed that improved stirring speeds up the supply of bleaching agent and fixing agent into the emulsion film, thereby increasing the desilvering speed. The agitation improvement means described above are more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect of the bleach accelerator.

As described in No. 67, such a conveyance means can significantly reduce the amount of processing liquid brought into the post bath from the front bath, and is highly effective in preventing deterioration of the performance of the processing liquid. Such effects are particularly effective in shortening the processing time in each step and reducing the amount of processing liquid replenishment.

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 used in the washing process depends on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the application, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. can be set over a wide range.

It can be determined by the method described in e1evision Engineers, Vol. 64L, P, , z 4Ar-, 2-3 (/F-3! Month issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of water used for washing can be significantly reduced, but due to the increase in water residence time in the tank, bacteria propagate and the generated suspended matter becomes a layer on the photosensitive material. Problems such as this arise. In the processing of color photosensitive materials of the present invention, as a solution to these problems,
