Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material, and more particularly, to a silver halide color photographic material which can effectively utilize a DIR compound and has excellent storage stability, development processing stability and coating film properties. It relates to a photosensitive material.

[0002]

2. Description of the Related Art In recent years, there has been a strong demand for silver halide color photographic light-sensitive materials having high sensitivity, high image quality and excellent color reproducibility.

As a means for improving image quality and improving color reproducibility, DI which reacts with an oxidized form of a color developing agent and releases a development inhibitor is used.
R compounds are known. It is well known that by including this in a light-sensitive material, sharpness by the edge effect and color reproducibility by the layering effect are improved. However, these DIR compounds have the disadvantage that the development inhibitor released during color development diffuses into the processing solution from the photosensitive material and accumulates, resulting in the processing solution exhibiting development inhibiting properties.

Compounds for solving such problems are disclosed in JP-A-57-151944 and JP-A-58-20515.

The means for coating the undercoat layer of the present invention is not particularly limited, and a known method can be used.
In general, the timing of applying the undercoat layer is before or after stretching during film formation of the support.

Further, in the present invention, after coating a layer containing a polymer having a 2-oxazoline group, the temperature may be 90 ° C. to 1 ° C.
The heat treatment is preferably performed at 50 ° C. for 1 minute or more. There is no particular limitation on the timing of the heat treatment. For example, the heat treatment can be performed continuously after the coating and drying of the layer. In addition, the heat treatment can also be performed together with the above-described heat treatment for curling reduction. (Description of Claim 3) In the present invention, the DIR compound can be effectively utilized by curing the undercoat layer on the photographic component layer side of the support with a vinylsulfone-type curing agent in the presence of a volatile organic acid. The effects of the present invention can be exhibited.

The volatile organic acid refers to a volatile or sublimable organic acid. In the present invention, these organic acids are useful substances for dispersing gelatin in an organic solvent which is a poor solvent for gelatin. It is believed that some bonding (eg, hydrogen bonding) between gelatin and an organic acid enables dispersion in an organic solvent, but after coating, the organic acid is contained in the undercoat layer coating film. Residuals cause various troubles, and must be removed from the coating film as much as possible.

The organic acids useful in the present invention include formic acid, acetic acid, propionic acid, salicylic acid, butyric acid, valeric acid, oxalic acid, benzoic acid, etc. Among them, formic acid and acetic acid are preferred, and pH To acetic acid is more preferred.

It is preferable to remove them. The pH in the undercoat layer can be measured as in the examples described later. When the organic acid remains in the undercoat layer, the reactivity of the below-described general formula vinylsulfone-based crosslinking agent in the undercoat layer is suppressed, and the undercoat layer is not cross-linked, and gradually works for a long time. A so-called post-hardening occurs and the product cannot be stabilized. In the present invention, after coating and drying, the organic acid evaporates or sublimates to adjust the film surface pH to 4.0 to 4.0.
By setting the pH to 6.0, the crosslinking reaction is completed immediately, a stable undercoat layer is obtained without any change over time, and the adhesion of the silver halide emulsion layer, the non-photosensitive layer and the back layer on the upper layer is improved. In particular, during the development processing, not only the adhesion after the processing is ensured, but also the performance such as sensitivity and fog is stabilized.

In the present invention, the initial drying after the application of the undercoat layer coating solution is carried out at 50 to 150 ° C., more preferably at 60 to 150 ° C.
120 ° C., particularly preferred is 80 ° C. to 110 ° C., 5 ° C.
The drying time is preferably 7 seconds or more, more preferably 7 seconds or more. By heating and drying in this way, the whitening phenomenon (also called brushing) immediately after application does not occur. And it is better to avoid it. In this case, it is better that the drying air is as gentle as possible, and the static pressure is 70 mmAq or less, preferably 2 mmAq or less.
It is 0 mmAq or less.

In order to remove the organic acid of the present invention from the undercoat layer after coating, the subsequent drying is performed at 120 to 200 ° C., preferably 130 to 180 ° C., more preferably 140 to 1 ° C.

Can be volatilized or sublimated.

The amount of the organic acid used in the present invention is 1 to 10% by mass, preferably 2 to 8% by mass, based on the undercoat layer coating solution.
It is.

(Description of Claim 4) In the present invention, the undercoat layer on the photographic constituting layer side of the support is formed of calcium ion (C
a.sup.2 ⁺ ) content of 400 ppm or less and sodium ion (Na.sup. ⁺ ) content of piperazine-treated gelatin of 8000 ppm or less, the DIR compound can be effectively utilized, and the effects of the present invention can be exhibited. it can.

Piperazine gelatin is one type of amine-treated gelatin. Amine-processed gelatin is gelatin extracted by adding a primary or secondary amine having no dissociable group during lime treatment at the time of production. .

A method of adding a primary or secondary amine having no dissociable group for the purpose of shortening the extraction time in the lime treatment step during the gelatin production step is known (US Pat. No. 2,184,494). .

As the primary or secondary amine having no dissociable group, a compound having a relatively small molecular weight is often used, and a compound having 5 or less carbon atoms is particularly preferably used.

Specific compounds include cyclic amines such as methylamine, dimethylamine, ethylamine, n-propylamine, ethylmethylamine, n-butylamine, guanidine, ethylenediamine, hydrazine or piperidine, piperazine and the like. In the present invention, piperazine is particularly preferable, and one using piperazine is referred to as piperazine gelatin.

These compounds are added to the lime suspension to a concentration of 0.01% to 0.1%.

The piperazine-treated gelatin used in the present invention uses piperazine from among the above-mentioned primary or secondary amines having no dissociable group, and reduces chlorine ion and calcium ion by the deionization step. It is desirable that it is done.

The chloride ion concentration is usually 500 ppm or less,
Preferably 300 ppm or less, more preferably 100 ppm
ppm or less, and the calcium ion is desirably 50 ppm or less.

The gelatin used as the main binder of the undercoat layer of the present invention will be described. Gelatin used in the present invention includes, in addition to acid-treated gelatin and alkali-treated gelatin, enzyme-treated gelatin and gelatin derivatives which are subjected to an enzyme treatment in the course of the production of gelatin, that is, amino, imino and hydroxyl groups as functional groups in the molecule. It may be modified by treating with a reagent having a group, a carboxyl group, and a group obtained by reacting with the group. General methods for producing gelatin are well known, for example, T.I. H. James:
The Theory of Photographi

millan) 55, Scientific Photograph Handbook (above) 72-75
Section (Maruzen), Basics of Photographic Engineering-Silver Halide Photography, 119-12
4 (Corona) etc. can be referred to.

For example, lime-processed gelatin is prepared as follows. First, ossein consisting only of collagen from which calcium phosphate has been removed is immersed (lime-soaked) in saturated lime water for 2 to 3 months, and then washed and neutralized.
Extract with hot water at 0 ° C (No. 1 extraction). Then 60-6
No. 2 extraction at 5 ° C., No. 3 extraction at 70-75 ° C., and No. 4 extraction at 80 ° C. or more. Each extract is filtered, concentrated under reduced pressure, cooled and coagulated at about 10 ° C., and then dried to obtain.

The ion exchange treatment of gelatin is performed immediately after the filtration treatment in the above-mentioned production process. For example, a method in which a gelatin aqueous solution is heated and brought into contact with an ion exchange resin can be used. As the ion exchange treatment, both ion exchange treatments can be used. The metal element in gelatin is usually present as a cation in many cases, and can be removed by a cation exchange resin. However, since it may be present as a negative complex salt, both ion exchange treatments are performed.

As a method of both ion exchange treatments, a method of performing anion exchange treatment after performing cation exchange treatment,
A method in which the cation exchange treatment is performed after the anion exchange treatment in the former order, or a treatment with both ion exchange resins and a chelate resin can be used. A base such as sodium hydroxide may be used as the anion exchange resin during regeneration. In this case, sodium ions (Na ⁺ ) may remain in the anion exchange resin. For this reason, it is more preferable to perform cation exchange after anion exchange to remove sodium ions (Na ⁺ ) mixed from the anion exchange resin. These methods are described in “Chemical Experiment Course 2, Basic Technology II” edited by The Chemical Society of Japan, Maruzen (1956), pp. 151-202, “New Experimental Chemistry Course 1, Basic Operation I” edited by The Chemical Society of Japan, Maruzen (1975), 463
497 pages.

The following can be used as the ion exchange resin. Cation exchange resin: Amberlite IR-20 (manufactured by Rohm and Haas) Anion exchange resin: Diaion SA-21A (manufactured by Mitsubishi Kasei), Dowex 1 × 8 (manufactured by Dow Chemical), etc. Resin and chelate resin: Diaion C
R-20 (manufactured by Mitsubishi Kasei Co., Ltd.) Many of these ion exchange resins are commercially available, and those suitable for the purpose can be easily obtained. As the resin material, not only a synthetic resin (for example, styrene-divinylbenzene copolymer) but also a natural resin (for example, a cellulose-based one) may be used. The shape of the resin is
It may be in the form of granules, powders, films, etc., and may be appropriately selected to be easily handled.

Further, Japanese Patent Application Laid-Open No. 7-270982 discloses a method for controlling aggregates by adjusting the content of calcium ions (Ca ²⁺ ). However, instead of simply adjusting the amount of calcium ions (Ca ²⁺ ), the cations in the gelatin are exchanged for hydrogen ions (H ⁺ ) and the anions are exchanged for hydroxide ions (OH ⁻ ) to form aggregates. The suppression effect can be further improved. By deionization treatment, calcium ions (C
a ²⁺ ) amount is 400 ppm or less based on dry gelatin, and sodium ion (Na ⁺ ) amount is 80 ppm based on dry gelatin.
It is preferably set to 00ppm or less, chlorine ions in the anion containing (Cl ^-) amount to dry gelatin 5
The content of sulfate ions (SO ₄ ²⁻ ) is preferably 100 ppm or less based on dry gelatin.
More preferably, the amount of calcium ions (Ca ²⁺ ) in the cations contained in gelatin is 200 ppm or less based on dry gelatin, and the amount of sodium ions (Na ⁺ ) is
The following are preferred 1500ppm with respect to the dry gelatin, chlorine ions in the anion containing (Cl ^-) amount of dry gelatin 300ppm or less with respect to, sulfate ion (S
O ₄ ^2-) weight is 50ppm or less with respect to dry gelatin.

It is well known that gelatin is an amphoteric electrolyte, and it is difficult for water to swell or dissolve because water has a small repulsive force at isoionic points where charge is most neutralized. PH of gelatin in which cations are exchanged with hydrogen ions (H ⁺ ) and anions are exchanged with hydroxide ions (OH ⁻ )
Indicates the vicinity of an isoionic point, and gelatin may be difficult to swell and dissolve, and may be difficult to handle when handled as an undercoating coating solution. As a countermeasure, sodium hydroxide may be added to gelatin after ion exchange, and it is necessary to adjust the amount of sodium ions (Na ⁺ ) introduced at this time so as to have the above-mentioned ion amount. (Description of Claim 5) In the present invention, the DIR compound can be effectively utilized because the support is a transparent cellulose ester film having at least one acyl group having 2 to 4 carbon atoms as a substituent. The effects of the present invention can be exhibited.

In the present invention, preferably, the degree of substitution of the acetyl group of the cellulose ester film is X, and the degree of substitution of the propionyl group and / or butyryl group is Y.
A cellulose ester film satisfying the following formulas (I) and (II) (I) 2.6 ≦ X + Y ≦ 3.0 (II) 0 ≦ X ≦ 2.5 is preferable.

The cellulose as a raw material of the cellulose ester film used in the present invention is not particularly limited, and examples thereof include cotton linter, wood pulp, and kenaf. Cellulose esters obtained therefrom can be mixed and used at an arbitrary ratio.

In the cellulose ester of the present invention, when the acylating agent is an acid anhydride (acetic anhydride, propionic anhydride, butyric anhydride), an organic acid such as acetic acid or an organic acid such as methylene chloride is used. The reaction is carried out using a solvent and a protic catalyst such as sulfuric acid. The acylating agent is an acid chloride (CH ₃ COCl, C ₂ H ₅ COCl, C ₃
In the case of H ₇ COCl), the reaction is carried out using a basic compound such as an amine as a catalyst. Specifically, it can be synthesized by the method described in JP-A-10-45804. The transparent cellulose ester film having at least one acyl group having 2 to 4 carbon atoms as a substituent used in the present invention is obtained by adjusting and mixing the amount of the acylating agent in accordance with each degree of substitution. . Cellulose esters are obtained by reacting these acyl groups with hydroxyl groups of cellulose molecules. Cellulose molecules are composed of a large number of linked glucose units, and the glucose unit has three hydroxyl groups. The number of acyl groups derived from these three hydroxyl groups is called the degree of substitution (mol%). For example, in cellulose triacetate, all three hydroxyl groups of a glucose unit are bonded to an acetyl group (actually, 2.6 to 3.0).

The cellulose ester of the transparent cellulose ester film having at least one acyl group having 2 to 4 carbon atoms as a substituent used in the present invention may be cellulose acetate propionate, cellulose acetate butyrate or cellulose acetate propionate. It is a cellulose ester to which a propionate group or a butyrate group is bonded in addition to an acetyl group such as nate butyrate. In addition, propionate is iso in addition to n-.

It can be measured according to D817-96.

The cellulose ester used in the present invention preferably has a number average molecular weight of 70,000 to 300,000 because of its high mechanical strength when molded. 8000 more
0 to 200,000 is preferred. (Description of Claim 6) In the present invention, the DIR compound can be effectively utilized, because the photographic component layer side of the support has been subjected to a plasma discharge surface treatment under an air pressure of 60 to 110 kPa. Can be demonstrated.

In the present invention, the plasma treatment includes corona discharge treatment, flame treatment, ultraviolet treatment, high-frequency treatment, glow discharge treatment, active plasma treatment, and discharge plasma treatment in gas. Medium discharge plasma treatment is preferred.

Regarding the discharge plasma treatment in gas, reference can be made to those described in Japanese Patent Application Nos. 10-97426 and 10-94468, and the apparatus, processing method and the like are used in the present invention. Can be done.

Here, the discharge plasma processing in gas will be briefly described with reference to FIG.

FIG. 1 is a schematic configuration diagram of a surface treatment apparatus.
FIG. 1 is similar to the drawing in Japanese Patent Application No. 10-97426, in which an apparatus based on flat electrodes is shown, but the shape, system, and the like are not limited thereto.

First, FIG. 1 will be described. Reference numeral 1 denotes a gas discharge plasma processing apparatus. At least 50% of the inert gas is used as an argon gas in the processing chamber 2 at or near atmospheric pressure to form a processing gas by mixing it with another reactive gas, an inert gas, or the like. And the inside of the processing chamber 2 is filled, so that the space between the pair of electrodes 6 and 7 also becomes the atmosphere of the processing gas. The photographic support 5 transported (conveyed) between the electrodes is subjected to an in-gas discharge plasma treatment. At this time, the preparatory chamber 3a is provided to shut off the air accompanying the support 5. It is good to provide. Support 5
Is continuously transported through the gap between the pair of electrodes 6 and 7 in the processing chamber 2. The pair of electrodes 6 and 7 are plate electrodes provided in the processing chamber 2. The electrodes 6 and 7 are made of a conductive metal (for example, stainless steel, aluminum, copper, or the like).
A, 7A, and dielectrics (for example, rubber, glass, ceramic, etc.) 6B, 7 covering a part of the electrode members 6A, 7A.
B (the coating may be all or part). Further, in FIG. 1, a plate electrode such as a pair of electrodes 6 and 7 is used, but one or both electrodes may be a cylindrical electrode or one may be a roll electrode. A high-frequency power supply 8 is connected to one of the pair of electrodes 6 and 7, and the other electrode 7 is grounded by a ground 8E.
It is configured to cause a discharge between the pair of electrodes 6 and 7.

Next, the processing gas used in the present invention will be described. In the support used in the present invention, at least 50% by pressure of the processing gas introduced into the processing chamber 2 is argon (Ar).
Discharge plasma treatment in gas is performed as a gas. As other processing gases, neon (Ne) gas, helium (He) gas,
There are inert gases such as krypton (Kr) gas and xenon (Xe) gas.
0% by pressure, but argon (A
It is preferable that r) gas is used as a main component and argon gas is set to 60% by pressure or more in order to obtain an efficient reforming effect.

The effect of the plasma discharge treatment in gas is that argon gas has a larger atomic weight than helium gas and a larger size as a monoatomic gas, and the argon gas is struck against the surface of the plastic support 5 during the treatment. Etching occurs to produce irregularities on the surface, and argon gas has an effective effect as a treatment not seen with helium gas. In addition, argon gas is less expensive than other inert gases, but can achieve a remarkable reforming effect.
Other inert gases, for example, krypton gas and xenon gas, require high power and high frequency to generate plasma using them, and the surface treatment is too strong.
The support 5 is damaged.

50% by pressure of the inert gas introduced by the present invention
Using the above as argon gas means that 50% by pressure or more of the introduced inert gas is argon gas, and the remaining inert gas may be mixed with another inert gas in less than 50% by pressure. It is preferable to mix a reactive gas to obtain a processing gas. The ratio of the reactive gas to the inert gas is preferably 0 to 0.30% by pressure, and
1 to 0.2% by pressure.

In the present invention, a reactive gas such as a nitrogen (N ² ) gas, a hydrogen (H ² ) gas, an ammonia (NH ³ ) gas, or a steam is contained as a gas other than the inert gas used for the processing gas. Then, a gas discharge plasma treatment is performed. The reactive molecules that have been separated (released) react on the surface of the support by the discharge plasma treatment in gas, and the -NH ² group,-
Chemically active groups such as an OH group, a -COOH group, and the like are expressed, and the chemical modification of the support 5 can be performed, which contributes to an increase in adhesiveness.

The discharge state of the gas discharge plasma treatment of the present invention is a discharge state similar to a glow discharge occurring in a vacuum, but by cutting off air accompanying the support, the discharge state of the present invention is reduced. The discharge state of the in-gas discharge plasma treatment becomes more suitable for the surface treatment.

The discharge intensity of the plasma discharge treatment in gas of the present invention is 50 W · min / m ² or more and 500 W · min / m ^{2 in order} to perform stable and effective treatment without causing arc discharge.
It is preferably less than m ² . By performing in-gas discharge plasma treatment on the side of the photographic support having the photographic component layer in this range, it is possible to achieve uniformity of treatment, finish without damage, and obtain excellent adhesion only. In addition, the effect of the present invention can be exhibited.

If it is larger than 0%, the effect of the present invention is small. The adjustment of the degree of swelling depends on the choice of the kind of binder, especially on the kind of gelatin and the kind of polymer in the mixed system of gelatin and other water-soluble polymers and the amount of addition thereof, and the kind of hardener for hardening the binder system. And the amount added to the binder. (Claim 9) When the product is completed by one multi-layer simultaneous multi-layer coating, or when the first 10 or more layers are multi-layer multi-layer multi-layer coating, the lowermost layer and 9 or more layers to be applied adjacent to the lowermost layer are applied. 250ml /
m ² or less, and when the lowermost layer, for example, ^two layers of an antihalation layer and an intermediate layer are separately coated, the total coating amount of all 10 or more layers including this lowermost layer is 250 ml / m ^2.
The following is preferred. If the upper limit is exceeded, the photographic constituent layer to be coated is likely to cause a coating deviation. In consideration of further reducing the drying conditions, a more preferable total of the coating amount is 200 ml / m ² .

The simultaneous multi-layer coating can be carried out using a multi-layer simultaneous coating apparatus described in JP-B-33-8977. For example, using a slide hopper type coating apparatus capable of simultaneously coating 11 or more layers with a type similar to the slide hopper type of n-layer simultaneous coating as shown in FIG. 1 described in JP-B-33-8977, etc. A predetermined application liquid is supplied to the slit of the slide, and is applied so as to overlap each other when flowing down the slide surface.

Referring to FIG. 2, the slide hopper type coating apparatus will be described. The tip C of the slide hopper type coating machine E is spaced apart from the support S on the support S running while being supported by the backup roller R. The coating is performed on the support S by bringing the coating solution bridge (referred to as bead portion) B in the vicinity thereof. The distance between the support S and the tip C is called "bead distance". At this time, a decompression chamber D for decompressing the back of the bead for stabilizing the bead portion B is provided, and the pressure is reduced by the decompression pump P _{0. The} degree of decompression at that time is referred to as “bead back pressure”.

The slide hopper type coating machine in the multi-layer simultaneous coating apparatus will be described. The coating liquids S _{1 to} Sn of _n layers (multiple layers are n layers) are sent to the coating machine by measuring pumps P _{1 to} P _n . through the cavity a ₁ to a _n, it flows out each of the slit n ₁ to n _n thin coating liquid film over the full width of the support S to the respective slide surface. The thin coating liquid films that flow out are superimposed in order from the top and become an n-layer superposed coating liquid film at the bead portion, which is applied to the support. The slide hopper type was named by being superimposed on the slide surface.

According to the slide hopper type coating apparatus, 10 to 20 layers can be simultaneously coated.
Preferred is a multilayer simultaneous application of up to 18 layers. Generally, the coating speed is 30 to 500 m / min, preferably 60 to 500 m / min.
To 300 m / min, more preferably 80 to 250 m / min.
min.

The applied photographic constituent layer is dried by a usual method. That is, the applied photographic constituent layer is cooled, solidified and dried immediately after the application.

The coagulation is usually carried out by contacting with low-temperature air having a dry-bulb temperature of -10 to 20 ° C. After the coating film is cooled and solidified, drying is performed by blowing a conventionally used gas. Drying with this wind usually has a dry-ball sensitivity of 15-4.
5 ° C., relative humidity 10 to 50% RH air 10 to 40 m
^This is done by blowing at a flow rate of ² min.
This method is preferable because it can prevent an increase in fog due to drying.

It can be prepared by a general method as described in 993.3. For example, it can be made using a wet lamination method, a dry lamination method, a hot melt lamination method, an extrusion lamination method, or a heat lamination method.

As the adhesive used when laminating, generally known adhesives can be used. For example, polyolefin-based thermoplastic resins such as various polyethylene resins and various polypropylene resins, a hot-melt adhesive, an ethylene-propylene copolymer resin, an ethylene-vinyl acetate copolymer resin, and an ethylene copolymer such as an ethylene-ethyl acrylate copolymer resin. Coalescing resin, ethylene-acrylic acid copolymer resin, thermoplastic resin hot melt adhesive such as ionomer resin,
Other examples include a hot-melt type rubber-based adhesive. Emulsion,
Representative examples of emulsion-type adhesives that are latex-type adhesives include polyvinyl acetate resin, vinyl acetate-ethylene copolymer resin, vinyl acetate-acrylate copolymer resin, and vinyl acetate-maleate copolymer. Emulsions of resins, acrylic acid copolymers, ethylene-acrylic acid copolymers and the like are available. Representative examples of latex-type adhesives include natural rubber and styrene-butadiene rubber (SB
R), rubber latex such as acrylonitrile butadiene rubber (NBR) and chloroprene rubber (CR).
Examples of the dry laminating adhesive include an isocyanate-based adhesive, a urethane-based adhesive, and a polyester-based adhesive. In addition, paraffin wax, microcrystal wax, ethylene-vinyl acetate copolymer resin, and ethylene-ethyl acrylate Known adhesives such as hot melt laminate adhesives, pressure-sensitive adhesives, and heat-sensitive adhesives blended with a polymer resin or the like can also be used.

More specifically, the polyolefin resin adhesive for extrusion lamination is a polymer of a polyolefin resin such as a polyethylene resin, a polypropylene resin, or a polybutylene resin, or an ethylene copolymer (EVA or EEA) resin. Like other LLDPE resins, copolymers of ethylene and other monomers (α-olefins), ionomer resins (ion copolymer resins) such as Surlyn of Dupont, Himilan of Mitsui Polychemicals, and Mitsui Petrochemical ( Admer (adhesive polymer). Other UV curable adhesives have also recently begun to be used. Particularly, LDPE resin and LLDPE resin are preferable because they are inexpensive and have excellent laminating suitability. or,
A mixed resin in which two or more of the above-mentioned resins are blended to cover the defects of each resin is particularly preferable.

For example, blending the LLDPE resin and the LDPE resin improves the spreadability and reduces the neck-in, so that the laminating speed is improved and the number of pinholes is reduced.

When the respective layers are bonded using the above-mentioned adhesive, it is preferable to laminate them so that the bonding strength is 360 g / 15 mm width or less.

In order to prevent the performance from deteriorating during storage, a method of providing the air-permeable portion of the present invention for releasing the internal moisture is, for example, by piercing once with a sharp needle having a diameter of about 0.5 mm and having a sharp tip. After the holes are formed, the holes can be provided by performing pseudo closing between the upper and lower rollers. As a result, the moisture-proof material closing the hole once opened acts as a ventilation valve, and when the package is placed in a high-temperature state, the internal pressure of the package increases and the generated moisture passes through the air-permeable portion. It is removed, and moisture from the outside becomes hard to enter because the pressure does not change from the inside.

The diameter of the needle used for providing the permeable portion is preferably in the range of 0.3 mm to 3.0 mm. When the amount is less than the range, water cannot be sufficiently removed, and when the amount is more than the range, pseudo blocking becomes incomplete and external moisture enters, and in any case, photographic performance is adversely affected, such as fogging and sensitivity reduction.

/ M ^2, and samples 102 to 105 were prepared by further changing DI-1 among the DIR compounds of the third, fourth, tenth and eleventh layers as follows.

[0214]

[Table 1]

(DIR Effect) The effectiveness of the action of the DIR compound was examined by the following method. That is, for each sample, a step wedge exposure for sensitometry with white light (1/200 second) and a ratten filter No. 1 manufactured by Eastman Kodak Co., Ltd. were performed. The sample was subjected to decomposition exposure with green light using No. 99, and the following standard development processing was performed.

The average gradation Gw of the red photosensitive layer during white exposure
(Minimum density value +0.1 to minimum density value +1.0) and the average gradation Gr (minimum density value +
0.1 to the minimum density value +1.0), and Gg / Gw was defined as the magnitude of the interimage effect in the multilayer. The larger this value, the greater the interimage effect, indicating that the DIR compound is acting effectively. (Development processing stability) Each sample was subjected to wedge exposure for sensitometry (1/200 second) using white light,
A density function curve D-LogE characteristic curve was prepared for each of the following standard development process and a density function curve in a case where active development was performed at a temperature of + 1 ° C. and a time of +30 seconds in the color development process of the standard development process. And the minimum concentration +0.1
From the exposure (logarithmic value) that gives the green light measurement density of
The green light measurement densities when the exposure amount was increased by 6 steps in LogE = 0.15 increments were obtained, and the standard deviation of the slope (γ) of the characteristic curve for each step was calculated as follows.
