Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic material for color diffusion transfer, and more particularly to a photographic material for color diffusion transfer using a primary amino color developing agent.

Many patent applications have already been filed for color diffusion transfer photographic materials using primary amino developing agents (described later), and little is known about their dye image-forming methods, dye image-providing substances, layer structures, formats, etc. However, all of them reacted with oxidized products of aromatic primary amino color developing agents to form dye images. Naturally, in such a photographic material for color diffusion transfer, it is an essential condition that the formed dye image be maintained stably. That is, after the formed dye image has been transferred to the image-receiving element, whether or not the photosensitive element and image-receiving element are separated, the processing composition simply remains spread.
The formed dye image is extremely unstable and usually fades over time or causes staining of the untransferred portion of the dye image, the so-called white portion. Although the number of technologies that have been developed to improve the above-mentioned phenomena is small, several patents have been filed so far.

For example, it is known from JP-A No. 48-5424 that the addition of aldehyde bisulfite adducts is particularly effective in preventing stains on white backgrounds. This additive reacts with excess unused aromatic primary amino color developing agent and diffuses into the receiving element to form a colorless product. It is believed that brown pollution will be reduced. Also, JP-A-47-151
From the description in No. 34, it is known that containing an isocyanate or bisulfite adduct in a polymer binder is also effective in preventing staining of a white background. It is believed that this also prevents contamination by a similar effect as described above. moreover,
From the description in JP-A-48-3836, it is known that the addition of bis(vinylsulfonyl) derivatives or polymers thereof is also effective, and the same effect as above significantly reduces the risk of contamination. It is said to be suppressive. As mentioned above, aldehyde bisulfite adducts,
Isocyanate bisulfite adducts, bis(vinylsulfonylalkyl) derivatives, or their polymers are effective in preventing staining of white backgrounds, but they all have little effect on fading of color images. .

Furthermore, in photographic materials for color diffusion transfer using primary amino color developing agents, stabilization of color images is generally very important.

That is, in general color photography, a processing solution (which is well known to have a significant negative effect on image stabilization) is used to process exposed photos externally using a processing bath such as an automatic processor. It is supplied to the element and then removed to the external system by post-processing such as fixing, water washing, and desilvering. That is, in such a case, a favorable operation for image stabilization is being performed. Furthermore, since photographic materials for color diffusion transfer contain processing liquid internally (i.e., integrated with the photosensitive element), it is easy to imagine that the image becomes extremely unstable, and in fact, It is a street. The object of the present invention is to provide a method for using an additive which significantly improves the above-mentioned drawbacks and is particularly effective in reducing staining of white backgrounds.

Another object of the invention is to provide a new method for image stabilization in photographic materials for color diffusion transfer, in particular for anti-fade technology. Another object of the present invention is to provide a photographic material for color diffusion transfer using a primary amino color developing agent which has the effect of stabilizing images and preventing staining of white backgrounds as described above.

Another object of the invention is to provide an image and/or
The present invention also provides new techniques for stabilizing images formed with photosensitive elements and for pollution control laws.

After various considerations, we have determined that the objects of the present invention are photophore elements comprising a non-diffusing dye image donor in combination with at least one silver halide emulsion layer and preferably the silver halide, a diffusing F! +. or an image-receiving element which fixes a diffusive dye formed from a dye image donor into an image by a direct or indirect oxidation reaction between a non-diffusing aromatic primary amino developing agent and a dye image donor, and which is exposed to light. A photographic light-sensitive material for color diffusion transfer comprising a processing composition for making the photosensitive element developable, and optionally other hydrophilic colloid layers; , or by including a compound having an N-methylol group (hereinafter referred to as "N-methylol compound") in the treatment composition.

In particular, it has been found that the present invention not only improves staining on white backgrounds, but also significantly improves fading of images.

In particular, the image stabilization effect obtained by the present invention is an excellent effect that cannot be obtained with conventional methods. Therefore,
The present invention provides a very effective technique for producing and using photographic materials for color diffusion transfer using primary amino color developing agents. Although the mechanism of action that causes the above-mentioned remarkable effects is not clear, we speculate as follows.

That is, after the primary amino color developing agent substantially acts during development after exposure, the remaining developing agent that does not participate in dye image formation and/or its oxidized product (oxidized by development, air, etc.) is rendered harmless by reacting with the N-methylol compound present in the system (probably due to the reaction between the amino group of this developing agent and the aldehyde released by decomposition from the N-methylol group compound during or after the development process). That is, the N-methylol group compound of the present invention is considered to act as a scavenging precursor of the above-mentioned developing agent and/or its oxidized product. The above-mentioned remarkable effects are unexpected and surprising to those skilled in the art, and are of great practical significance.

This amount of additive usually corresponds to a molar amount equivalent to or more than the amount of primary amino color developing agent present after the start of the development process.

- Requires scavenging and inactivation by methylol compounds. For this reason, all methods are preferred in which the N-methylol compound of the present invention is added to a location where it acts as a scavenger after the photosensitive element has been substantially fully developed. For example, it is preferable to include the N-methylol compound of the present invention in the image-receiving element, and it is also effective to have it present on the side far from the photosensitive element when viewed from the direction in which the processing composition permeates.
It is also possible to encapsulate the N-methylol compound of the present invention and include it in the photosensitive element. For example, such capsules may contain polymers that do not break immediately upon contact with the treatment composition, but break down after a certain period of time, such as U.S. Pat. No. 3,421,892;
By using a so-called molecular sieve type polymer as described in No. 25685 and No. 3421892, the N-methylol compound of the present invention can be incorporated into a photosensitive element. Of course, when the N-methylol compound is included in the image receiving element, it constitutes the image receiving element.

For example, it can be included in at least one of the image-receiving layer, the neutralization rate controlling layer, and the neutralizing layer. It is also possible in this case to provide a new layer in the image-receiving element containing the N-methylol compound of the invention. The dye image donor (which may be either diffuse or non-diffusive, but non-diffuse is preferred) used in the present invention is a result of development of an image-exposed silver halide emulsion, and the dye image-donor (diffusive or non-diffusive) is a dye image donor that responds to light exposure with a diffuse dye. It is a compound that can provide a two-dimensional distribution of Here, ``diffusion l
"Dye" shall also include diffused dye precursors.

The dye image donors can be classified into the following representative types based on the various ways in which they lead to the generation of diffuse dyes.

(a) Dye image donor in which oxidation by silver halide is directly or indirectly linked to the provision of a diffuse surrounding dye: (1
) A type in which a change in the diffusion envelope occurs as a result of oxidation of a dye image donor by silver halide (for example, those commonly referred to as dye developers fall under this category, and those that release dyes and those that do not) (11) Dishes of the type in which the product oxidized directly or indirectly by silver halide (e.g. oxidized developer) reacts with the dye image donor to release a diffused dye. (b) components that remain unconsumed by development and the subsequent reactions that occur with development; Dye image donor for forming a diffused surrounding dye image using a dye image donor as a source: (2) A dye image donor that uses a limited amount of developer to move the developer not used in development to the image-receiving layer ( The system may contain an oxidizing agent), a type that converts to a dye (in which case the dye image donor is present in the image-receiving layer), and a system that can be developed using a limited amount of developer. A reaction in which the unused developing agent reacts with the dye image donor to give a diffused surrounding dye. An image donor of the type in which unused reactive components (for example, unreacted dye parts are released) is transferred to the image-receiving layer and converted into dye; Types in which silver ions obtained from unused silver halide are reacted with a dye image donor to give a diffused surrounding dye; (c) Dye image donor that releases a development inhibitor: 1. (IX) A type that releases a substituent that becomes a development inhibitor from a reactive position along with a coupling reaction, and (IX) a type that releases a substituent that becomes a development inhibitor from a reactive position. These include a type that releases a development inhibitor through a second reaction with a processing component.

The dye image donor used in the diffusion transfer color photography of the present invention may already contain a completed dye structure;
A dye structure may be formed during development and subsequent steps occurring simultaneously, and furthermore, components essential for dye formation may migrate to the image-receiving layer, where the dye may be formed.

The dye image donor itself used in the diffusion transfer color photography of the present invention is preferably non-diffusive in the photosensitive element during the production, storage and exposure stages of the photosensitive material, but it is preferable that the dye image donor itself is non-diffusive in the photosensitive element during the production, storage and exposure stages of the photosensitive material. The stages can have various forms of diffusion notes depending on the method of forming the dye image distribution.

For example, in one form, a dye image donor that is dissolved and diffused in the processing composition becomes immobilized by a reduction of the diffusive groups as a result of development, and the undeveloped portions of the dye image donor become immobilized. transferred to the layer. In other forms, the dye image-donor itself is non-diffusive in the processing composition, but releases diffuse surrounding dye as a result of development. In the present invention, dye image donors with various combinations of the above-mentioned development to dye conversion method, dye structure formation stage, and diffusion range may be used, but particularly useful ones include: It is as follows.

Diffusive dye-releasing puller: A reactive non-diffusive compound that can couple with an oxidized developing agent, and as a result of the coupling reaction, releases a soluble and diffused dye into the processing composition. can do.

A first type of compound, a diffusive dye-releasing agent, contains a structural moiety in which the coupling reactive site is replaced by a group that is releasable by oxidized developer. The electronically conjugated system of the dye to be released may be pre-incorporated into the coupler or may be formed by a coupling reaction. The former can be called "pre-formed," and the coupler exhibits a spectral absorption similar to that of the emitted dye.

On the other hand, the latter can be called "immediately forming" and capnilla is basically colorless, but it can be colored if desired. This is because even if the dye is colored, its absorption is not directly related to the absorption of the emitted pigment. Typical diffusive dye releasing power can be expressed by the following five general formulas.

() (Cp-1)-L-(Fr) (“pre-formed”) and () (Cp-2)-L-(Rt) (“immediately-formed”) where Cp-1 indicates that the coupling position is (Fr)-L is substituted by one residue (MOiety), and at least one non-coupling position contains a hydrophobic surrounding group having 8 or more carbon atoms, and a group that provides a diffusion-resistant surrounding to the coupler molecule. Cp-2 represents a structural moiety of the coupling reaction active box such that the coupling position is (Bt)-L
Represents the structural part of the coupling reaction circle that is replaced by a single residue.

Furthermore, when used in combination with a developing agent that does not have a Mizumachi solubilizing group, the Cp-2 group has a water solubilizing group in at least one of the non-coupling positions. One (Fr)-L group and one (Bt)-L group represent groups that are eliminated by the oxidized form of the developing agent. F" represents a structural part of a dye (or its precursor) that has absorption in a visible wavelength range or a non-circular wavelength range and has at least one water-solubilizing group;
t represents a group containing a hydrophobic surrounding group having 8 or more carbon atoms and imparting diffusion resistance to the coupler molecule.

Cp-1 and Cp-2 can include many functional groups capable of coupling with the oxidized form of an aromatic primary amino color developing agent. Examples include phenols, anilines, cyclic or chain active bent methylene compounds, and hydrazones. Particularly useful examples of these include phenols substituted with acylamino groups 1
-Hydroquinyl-2-naphthoic acid amide, N,N-dialylaniline, 3rd position is alkyl, aryl, alkyl, aryl, aminoacylaminoureido,
or 1- substituted with a sulfonamide group, etc.
Aryl-5-pyrazolones, pyrazolobenzimidazoles substituted with groups as described above, pyrazolotriazoles substituted with groups as described above, α-cyanoacetophenes substituted with groups as described above It is a functional group derived from α-acylacetanilide or the like substituted with a group such as non, or the above-mentioned group. The linking group L whose bond with the coupler is broken by the oxidized developing agent is an azo group, an azo group, a mercury group (-Hg-)
, oxy group, thio group, dithio group, triazolyl group, diacylami/\no group, acylsulfonamino group (0=
Examples include CSO2), ~'acyl group, sulfonyl group, and alkylidene group.

Among these, dye-forming efficiencies are high in the case of oxy groups, thio groups, dithio groups, diacylamino groups, acyloxy groups, etc., which leave off as anions, and therefore are useful because they release a large amount of diffusive dye. For example, the coupling position of the coupling structure of phenol or naphthol is
Preferably, the coupling position of the pyrazocane is substituted via an azo, thio, or acyloxy group by other groups or dye structural moieties, while the acylacetanilide is substituted via a thio, thio, or acyloxy group. The coupling position of is preferably substituted with other groups or dye structural moieties via an oxy group, a thio group, or a diacylamino group, respectively. Representative examples of Fr include residues derived from γzo dyes, azomethine dyes, indoaniline dyes, indophenol dyes, anthraquinone dyes, nitro dyes, azine dyes, and the like.

The hydrophobic surrounding group contained in Cp-1 or the hydrophobic surrounding group typified by Bt provides cohesive force between coupler molecules in an aqueous medium, and causes non-diffusion and do. As the hydrophobic surrounding group, an aliphatic group having 8 or more carbon atoms (for example, a substituted or unsubstituted alkyl group, alkenyl group, aralkyl group, etc., an aryl group or an aryloxy group) is advantageously used.

For example, lauryl group, stearyl group, oleyl group, 3-n
-pentadecyl phenyl group, 2,4-di-t-amylphenol group, etc. These hydrophobic surrounding groups can be directly or, for example, amide bonds, ureido bonds, ether bonds, etc.
Cp-1 can be formed by bonding to the coupling basic structure via a divalent bond such as an ester bond or a sulfonamide bond. Moreover, these hydrophobic l groups may form Bt by themselves, or by bonding to groups such as aryl groups or heteromonkey groups directly or via the above-mentioned divalent bonds. The Mizumachi solubilizing group contained in Cp-2 or Fr is an acid surrounding group that substantially dissociates in the treatment composition or a precursor group that provides it upon hydrolysis.

In particular, acid annotations having a PKa of 11 or less are useful. Examples of such groups include sulfo group, sulfo group (-0-S
O3H), carboxyl group, sulfonamido group, diacylamino group, cyanosulfonamino group, phenol hydroxyl group, etc. When the diffusive dye-releasing coupler of the general formula () reacts with an oxidized developing agent, the bond L is cleaved to form a non-diffusive enclosure condensate of Cp-1 and the developing agent, and a possible compound containing an Fr structure. It forms a fusion pigment. This injected dye diffuses into the image-receiving layer to form a dye image. When a diffused dye-releasing coupler of the type represented by the general formula () reacts with an oxidized developing agent, the bond L is cleaved and the Cp-2
The oxidative coupling product of the oxidative coupling of Bt-L- with the developing agent gives a non-diffusive separation product derived from Bt-L-.

In the second type of compound, a diffusive dye-releasing puller, the substituent group undergoes an intramolecular ring-closure reaction with a substituent adjacent to the reactive site following a general reaction with the oxidized developing agent. The dye residues contained in the dye are cleaved and released.

In particular, after the oxidized product of an aromatic primary amino developer is coupled to the 4-position of phenol or aniline, an azine ring is formed with the sulfonamide group containing the dye structure located at the 3-position, and the sulfonic acid Reactions that release a diffused dye having a chromophore (for example, the reaction described in Japanese Patent Publication No. 48-32129) are useful.

No. 3,719,492. is useful because it can be added to the photosensitive material. A negative-working silver halide emulsion layer containing a coupler that releases a diffusion dye provides a negative diffusion transfer dye image upon processing.

In contrast, a direct positive silver halide emulsion layer containing a coupler that releases a diffuse dye provides a positive diffusion transfer dye image. As a direct positive emulsion, U.S. Patent No. 2,59

Coupled type emulsions described in et al. are useful.

A positive diffusion transfer dye is produced by treating a layer adjacent to a negative silver halide emulsion layer containing a coupler and physical development nuclei that release a diffusion dye with a developer containing a silver halide solvent. An image is obtained. As a reversal dye image forming technology using this physical development, German Patent No. 2,136,
No. 994 or British Patent No. 904,364 can be used. Furthermore, a diffusion dye is placed adjacent to the negative-working silver halide emulsion layer containing a compound (DIR compound) that reacts with the oxide of the developing agent to release a development inhibitor such as 1-phenyl-5-mercaptotetrazole. Photosensitive elements with layers containing emitting couplers and spontaneously reducible metal salts are disclosed in U.S. Pat. No. 3,227,551;

The present invention can be applied to combination systems of these emulsions and dye image donors, and a method for providing a negative or positive dye image can be selected depending on the purpose. The development inhibitor-releasing compound (so-called DIR compound) used in the present invention includes (1) an aromatic primary amine.

The DIR compound used in the present invention must contain a hydrophobic surrounding residue having 8 or more carbon atoms in the molecule and be diffusion resistant. The hydrophobic surround residues can be the same as those used in conventional diffusion-resistant surround couplers. The leaving function group of the DIR compound may already have a chemical structure having a development-inhibiting effect before leaving, or may complete the development-inhibiting chemical structure only after leaving.

An aqueous halide such as potassium chloride is reacted in a protective colloid solution such as gelatin to cause crystal growth in the presence of excess halide or a silver halide solvent such as ammonia. Single or double jet method, PAg control.Double jet precipitation method can be used.Removal of surrounding salts from the emulsion can be carried out by washing the cooled and coagulated emulsion with water, dialysis, sulfon group, sulfate ester group, carboxyl group, etc. This can be achieved by adding a precipitant such as an anionic polymer having a silyl group or an anionic surfactant and adjusting the pH, or by using an acylated protein such as ptalol gelatin as a protective colloid and precipitation by adjusting the pH.

Emulsions that tend to form latent images on grain surfaces are also disclosed in U.S. Pat. No. 2,592,550;
Emulsions that easily form latent images inside the grains, such as those described in US Pat. No. 06,313, can also be used.

In addition, inorganic compounds such as complex salts of platinum group elements such as cadmium salts, mercury salts, and chlorocomplex salts of palladium are also useful for stabilizing the photosensitive material of the present invention. Furthermore, the silver halide emulsion used in the present invention may contain a sensitizing compound such as a polyethylene oxide compound. The silver halide emulsions used in the present invention may have a color sensitivity extended by optical sensitizing dyes, if desired.

Useful optical sensitizers include cyanines, merocyanines, holopolar cyanines, styryls, hemicyanilins, osanols, and S)S myosanols.

It is convenient to apply multiple layers simultaneously using a multi-slit hopper as described in No. 419; No. 2,761,791. In order to facilitate the application of the photographic layers used in the present invention, it is advantageous for the coating composition to contain various surfactants as coating aids.

Useful coating aids include saponin, nonionic surfactants such as diethylene adducts of p-nonylphenol, alkyl ethers of sucrose, monoalkyl ethers of glycerin, sodium dodecyl sulfate, and p-dodecylbenzene sulfon. Acid sodium salt dioctyl sulfosuccinate. Anionic surfactants such as sodium salts and carpoxmethyldimethyllauryl ammonium. Hydroo no side internal salt, ``DeriOhatl5l'',

In addition to those which increase the viscosity of the coating composition by their own viscosity, such as high molecular weight polyacrylamides, cellulose sulfate, poly-p-sulfostyrene. Potassium salts and anionic polymers that exhibit thickening effects by interaction with binder polymers in coating compositions, such as the acrylic acid-based polymers disclosed in U.S. Pat. No. 3,655,407, may also be used. Useful. The processing composition used to create a color photographic image of the present invention is a liquid composition containing processing components necessary for developing a silver halide emulsion and forming a diffusion transfer dye image, and the solvent is mainly water. It may also contain other hydrophilic solvents such as methanol and methyl cellosolve. The processing composition contains an amount of alkali sufficient to maintain the pH necessary for development of the emulsion layers to occur and to neutralize acids formed during the development and dye image formation steps. As the alkali, sodium hydroxide, potassium hydroxide, calcium hydroxide, tetramethylammonium hydroxide, sodium carbonate, trisodium phosphate, diethylamine, etc. are used, and the composition preferably has a pH of about 12 or more at room temperature. More preferably, the treatment composition contains a hydrophilic polymer such as high molecular weight polyvinyl alcohol, hydroxyethyl cellulose, sodium carboxymethyl cellulose. These polymers give the processing composition a viscosity of 1 poise or more, preferably about 1000 poise, at room temperature, and not only facilitate uniform spread of the composition during processing, but also viscosity of the photosensitive element during processing. When the processing composition is concentrated by migration of the water and solvent into the image receiving element, it forms a non-flowing film which helps the film unit to be integrated after processing. This polymer film can also be used to inhibit further migration of colored components to the image-receiving layer after the formation of the diffusion-transferred dye image is substantially completed, thereby preventing changes in the image. The processing composition may also include a light absorbing material such as carbon black to prevent force pulling of the silver halide emulsion by external light during processing, as well as U.S. Pat. No. 3,579,333.
It may be advantageous in some cases to contain desensitizers as described in No.

Advantageously, the treatment composition used in the present invention is housed in a breakable container.

Such containers contain the processing composition in a cavity created by folding a sheet of liquid- and air-impermeable material and sealing each end so that the film unit is not allowed to pass through the pressure device. Advantageously, the treatment composition is adapted to burst and release its contents at a defined point by the internal pressure exerted on it. Materials such as polyethylene terephthalate/polyvinyl alcohol/polyethylene laminates, lead foil/vinyl chloride and vinyl acetate copolymer laminates are advantageously used as materials forming the container. Preferably, the containers are secured along the leading edge of the film unit and are adapted to spread the liquid contained therein in a substantially unidirectional manner onto the surface of the photosensitive element. A preferred example of a container is U.S. Pat. No. 2,543,181.

3,152,515, and such containers are advantageous in the practice of the present invention. Advantageously, the image-receiving element used in the present invention contains a base hyperpolymer or a base surfactant.

As base-surrounding polymers, those containing tertiary or quaternary nitrogen atoms are preferred, specifically poly-4-vinylpyridine; vinyl methyl ketone aminoguanidine described in U.S. Pat. No. 2,882,156; Polymer of derivative; poly-4-vinyl-N-benzyl-pyridinium,

In addition to these basic compounds, compounds of polyvalent metals such as thorium, gamma luminium, and zirconium have a fixing effect on anion group pigment-forming substances. These materials can form films with polymers such as gelatin (particularly acid-treated gelatin), polyvinyl alcohol, polyacrylamide, polyvinyl methyl ether, hydroethyl cellulose, N-methoxymethyl polyhexylmethyleneadipamide, and polyvinylpyrrolidone. is advantageous. When the dye image-forming substance is a dye-forming component such as a diffuse band coupler, the image-receiving layer contains other coupling components that react with this component to form the dye, such as p-phenylenediamine derivatives and oxidizing agents or diazonium. Contains compounds. This type of image receiving element includes U.S. Pat. No. 2,647;

Those described in British Patent No. 2,735, British Patent No. 3,676,124, British Patent No. 1,158,440, British Patent No. 1,157,507, etc. can be used. The diffusion transfer photographic material (film unit) of the present invention preferably has a function of neutralizing alkali brought in from the processing composition.

A pH high enough to promote the imaging process consisting of development of the silver halide emulsion, formation and expansion of the diffusion dye image former, etc.
1 The treatment composition contains Terkali to provide a pH of 10 or more, preferably 11 or more. After the formation of the diffusion transfer image is substantially completed, the p in the film unit is
Neutralizing H to around the middle range, below 9, preferably below 8, virtually stops further image formation process, prevents changes in the tone of an image over time, and improves image quality caused by high alkalis. Prevents discoloration, fading, and contamination of white areas. For this purpose, it is necessary to contain a sufficient amount of acidic material to neutralize the alkali in the processing solution to the above pH, that is, an acid surrounding material with an areal concentration equal to or higher than that of the alkali in the developed processing solution. 2
It is advantageous to incorporate a neutralizing layer 12 as shown in the film unit. Preferred acid surrounding materials include materials containing acid surrounding groups with a pKa of 9 or less, particularly carboxyl or sulfonic acid groups, or precursor groups that provide such acid surrounding groups upon hydrolysis, more preferably those described in U.S. Pat. Higher fatty acids such as oleic acid described in US Pat. No. 2,983,606 and US Pat. No. 3,362,81
Examples include polymers of acrylic acid, methacrylic acid, or maleic acid, and partial esters or acid anhydrides thereof, which are described in No. 9.

Specific examples of polymeric acid surrounding materials include vinyl monomers such as ethylene, vinyl acetate, and vinyl methyl ether;
A copolymer with maleic anhydride and its n-butyl half ester, a copolymer with butyl acrylate and acrylic acid,
Cellulose. Examples include gamma acetate phthalate. In addition to these acid bending substances, the neutralizing layer 12 contains cellulose. It may contain polymers such as nitrate, polyvinyl acetate, and may contain plasticizers as described in US Pat. No. 3,557,237. Further, the neutralization layer 12 may be cured by a crosslinking reaction using a polyfunctional aziridine compound, an epoxy compound, or the like. Neutralizing layer 12 is disposed in the image receiving element and/or the photosensitive element.

It is particularly advantageous if it is located between the support of the image-receiving element and the image-receiving layer. As described in DE 2,038,254, acidic substances can be incorporated into film units in microencapsulation. It is desirable that the neutralization layer or acid substance-containing layer used in the present invention be separated from the developing treatment liquid layer by a neutralization rate regulating layer.

This neutralization rate adjusting layer is used to reduce the density of the transferred image due to the premature decrease in the pH of the process before the required development of the silver halide emulsion layer and the formation of the diffusion transferred image. It serves to prevent undesirable decreases and to delay the decrease in pH until after the required development and transfer have taken place. In one of the preferred embodiments of the present invention, the image receiving section has a multilayer structure including a support, a neutralizing layer, a neutralization rate controlling layer, and a mordant layer (image receiving layer).

(However, the layer composition is not limited to this.) The neutralization rate adjusting layer may include gelatin, polyvinyl alcohol, polyvinyl propyl ether, polyacrylamide, hydropropyl methyl cellulose, isopropyl cellulose, partially polyvinyl butyral, partially hydrated It is composed mainly of a polymer such as a copolymer of decomposed polyvinyl acetate β-hydrodiethyl methacrylate and ethyl acrylate. These polymers are usefully cured by cross-linking reactions using aldehyde compounds such as formaldehyde or N-methylol compounds. Preferably, the neutralization rate controlling layer has a thickness of 2 microns to 20 microns. The light-sensitive element used in the present invention has a silver halide emulsion combined with a dye image donor.

The combination of the color sensitivity of the silver halide emulsion and the spectral absorption of the dye image is appropriately selected depending on the intended color reproduction. Reproduction of natural colors by the subtractive color method requires a light-sensitive element having at least two combinations: an emulsion with selective spectral sensitivity in a certain wavelength range and a compound providing a dye image with selective spectral absorption in the same wavelength range. used. In particular, combinations of blue-sensitive silver halide emulsions with compounds that provide a yellow dye image, combinations of green-sensitive emulsions with compounds that provide a magenta dye image, and combinations of red-sensitive emulsions with compounds that provide a cyan dye image. Photosensitive elements containing the combination are useful. These combined units of emulsion and dye image donor are coated in layered form in a face-to-face relationship in the photosensitive element, or they are each formed into particles and mixed and coated. In a preferred multilayer structure, from the exposed side, a yellow dye α-donor layer, a blue-sensitive silver halide emulsion layer,
Yellow filter layer, magenta dye donor layer, green-sensitive silver halide emulsion layer, intermediate layer, cyan dye image donor layer,
Red-sensitive silver halide emulsion layers are sequentially laminated, and especially in the case of a high-speed emulsion containing iodide, even if a yellow filter layer is placed between the blue-sensitive emulsion and the green-sensitive emulsion. good. The first layer of the yellow filter is a yellow colloidal silver dispersion,
It includes a dispersion of an oil-soluble yellow dye, an acid surrounding dye mordanted with a basic surrounding polymer, a basic surrounding dye mordanted with an acid surrounding polymer, and the like. Advantageously, the emulsion layers are separated from each other by interlayers. The interlayer prevents undesirable interactions between emulsion layer units of different color ranges. In addition to hydrophilic polymers such as gelatin, polyacrylamide, and partially hydrolyzed polyvinyl acetate, the intermediate layer may be made of hydrophilic polymers such as gelatin, polyacrylamide, and partially hydrolyzed polyvinyl acetate.
Polymers with pores formed from latexes of hydrophilic and hydrophobic polymers as described in US Pat. No. 5,685; treated compositions such as calcium alginate as described in U.S. Pat. It is composed of a polymer that gradually increases its hydrophilicity. The interlayer may contain interlayer interaction inhibitors selected depending on the type of dye image donor and processing composition used.
For example, in a type of dye image donor that releases a diffusible dye by an oxide of a developer, a diffusion-resistant curved coupler capable of reacting with and fixing a reducing agent such as a diffusion-resistant hydronone derivative and an oxidation product is used. It is effective in preventing undesirable exchange of developer oxidation products between emulsion layer units. Furthermore, in systems in which image reversal is performed by dissolution physical development, the intermediate layer contains physical development nuclei such as metal silver colloids in addition to these, and in systems in which image reversal is performed using a development inhibitor releasing (DIR) compound, the sensitivity is low. It is useful to contain fine silver halide grains, respectively, in order to obtain good color reproduction. In one preferred embodiment of the invention, the image-receiving layer is located between the transparent support and the light-reflecting layer that is transparent to the processing composition, and the dye image formed by processing is transparent. Viewed through the support, there is no need to separate the image-receiving element from the photosensitive element after image transfer.

Specific examples of films and units with such functions are U.S. Pat. Nos. 2,983,606; 3,415,644;
3,415,645; 3,415,646; 3,594
, 164 and 3,594,165.
In one type of non-strippable film unit, the silver halide emulsion associated with the dye image donor is coated on a light-opaque support and imagewise exposed from the side opposite the support.

After exposure, a processing composition is spread in a layer between the surface of the silver halide emulsion layer and the image-receiving layer on the transparent support. The processing composition contains a light-reflecting substance, and the dye image formed by diffusing into the image-receiving layer through the processing liquid layer is observed through the transparent support. In this film unit, it is necessary to use a camera with a special optical system such as mirror reflection in order to obtain a correct image that is not left and right reversed. In other film units of the non-stripping type, the silver halide emulsion associated with the dye image donor is coated on a transparent support and imagewise exposed through the support.

After exposure, a processing composition is spread in a layer between the surface of the silver halide emulsion layer and the image-receiving layer on the transparent support. Diffusion occurs through the processing solution against the background of a light-reflecting material that is pre-arranged in a layer between the silver halide emulsion layer and the image-receiving layer or a light-reflecting material that is contained in the processing composition and is developed in a layer. The dye image fixed on the image-receiving layer is observed through the transparent support. In yet another non-peelable film unit, an image-receiving layer, a light-reflecting layer, a light-shielding layer containing a light-absorbing substance, and a silver halide emulsion layer combined with a dye image donor are sequentially coated on a transparent support. The material is exposed imagewise from the side opposite the support.

A processing composition is then spread on the silver halide emulsion surface. The dye image diffused through the light-shielding layer and the light-reflecting layer and fixed on the image-receiving layer is observed through the transparent support. The surface of the silver halide emulsion layer is covered with a transparent sheet, and light is exposed through this cover sheet, and a processing composition containing a light-absorbing substance is developed between the cover sheet and the surface of the emulsion layer. Film units designed as such are particularly useful. In the present invention, a light-reflecting material is used to form a white background for the dye image formed on the image-receiving layer.

Suitable light-reflecting materials include barium titanium dioxide sulfate, zinc oxide, alumina, barium ste-T phosphate, calcium carbonate, silicate, zirconium oxide, kaolin.
Examples include magnesium oxide, which can be used alone or in combination. Such light reflective surrounds may be preformed or as described in Pelkey Patent No. 768,110, 76
It may be formed in-situ from a precursor which is distributed in a film unit as described in US Pat. No. 8,111. The light-reflecting substance may be contained in a layer using a hydrophilic polymer such as polyvinyl alcohol, gelatin, hydroxyfuropylcellulose, or polyvinylpyrrolidone as a binder, and may be further incorporated in the processing liquid composition. It can also be fixed in a dispersed state in a layer of a film-forming polymer such as hydrodiethylcellulose or carboxydimethylcellulose formed by spreading a treatment solution. A beautiful white background can be obtained by using a fluorescent whitening agent such as stilbene, coumarin, triazine or oxazole together with a light reflecting material. To protect the silver halide emulsion layers from ambient light during processing, the use of light-reflecting surrounds as described in Pelkey Patent Nos. 743,336, 768,107, and 768,109, P.K.
It is advantageous to have a dye present which is colored at a pH of a or above and becomes colorless at a pH of PKaO)p...nu.

Advantageously, the layer containing the light-reflecting material has a composition of light-reflecting material/binder polymer (weight ratio) from about 0.5 to about 100 and a dry film thickness of from 5 microns to 50 microns. and has a light reflectance of 50% or more, preferably 70% or more. The photographic material of the invention has a breakable container containing the processing composition.

When this container is pushed out by the pressure tool, it ruptures due to internal pressure, releasing the treatment composition in a defined manner. Although various pressure tools can be used, a pressure tool consisting of at least one pair of members juxtaposed with a certain gap is particularly suitable for processing the film unit of the present invention. A pair of members are either fixed with a fixed gap or pressed together with a fixed force by a projectile such as a spring, and the members are rod-shaped, freely rotating rollers, or driven by a roller. You can use a roller or the like.

As the film unit passes between the juxtaposed pair of pressure tools, the container is ruptured and the processing composition is released and further spread in a layer between the two sheets. As juxtaposed pressure tools, US Pat. No. 3,647,441; 3,6
52,281 are advantageously used. With the photographic material of the present invention, the development process can be continued in a bright place outside the camera. In this case, the silver halide emulsion layer is protected from external light until development and dye image transfer are substantially completed. For this purpose, it is advantageous to arrange a light-shielding layer containing a light-absorbing substance on the side surface of the silver halide emulsion layer. Depending on where it is placed, the light-shielding layer is either transparent to the processing composition (hydrophilic) or impermeable to the processing composition (dimensionally stable). The treatment composition transparent group light-shielding layer is a water-permeable polymer layer containing a light-shielding substance such as gelatin, polyvinyl alcohol, polyacrylamide, polyhydromethylcellulose, carboxymethylcellulose, sodium salt, methylcellulose, etc., and can be used as a pre-formed layer. It may be coated, or it may be developed in a processing manner as a processing liquid layer.
The dimensionally stable light-shielding layer is a polymer layer containing a light-absorbing substance, as described in Japanese Patent Publication No. 43-24,547 and U.S. Pat. No. 3,607,818. It is incorporated into the film unit as a light shielding sheet. The dimensionally stable light shielding layer can also be made of a metal foil such as aluminum or tin, a laminate film of a metal foil and a polymer, or a film and a laminate film in which aluminum is vapor-deposited on polyethylene terephthalate. It is preferable to cover the light-shielding layer with a light-reflecting material such as titanium dioxide from the viewpoint of increasing the light-shielding area and improving the appearance. Various light-absorbing materials can be used in the light-shielding layer, but in particular carbon powders such as carbon black, silver colloids, organic pigments such as azo lake or copper phthalocyanine, water-insoluble gamma dyes, anthratonone dyes, etc. Particularly useful are dispersions of dyes, polymers reacted with reactive dyes, hydrophilic injection dyes with micelle-forming surrounds, and the like.

Although it varies depending on the purpose of use of the film unit, the light shielding layer has an absorbance (scattered light) of about 3 or more, preferably 5 over the entire wavelength range from 350 to 650 millimicrons, preferably from 300 millimicrons to 750 millimicrons. The above is necessary in many cases. The dimensionally stable light-shielding layer can advantageously be used as an adhesive tape to light-shield the edges of the transparent support in order to prevent light leakage from the edges of the film unit into the silver halide emulsion layer.

) An image-receiving element (4) was prepared by coating each layer on the support in the following order:

A. l. Acidic layer for neutralization Monobutyl ester of a 1:1 copolymer of maleic anhydride and vinyl methyl ether (average molecular weight 100,000)
(20% by weight ethyl acetate) solution was applied to form a dry film with a thickness of 20 μm.

2. Neutralization rate control layer 2 - Copolymer of hydroxyethyl methacrylate and butyl methacrylate 80:20 (average molecular weight approximately) 5
Add 6 ml of a 10% aqueous solution of polyethylene glycol 39 and trimethylolmelamine to a solution of 49 dissolved in 126 ml of a 4/1 ethanol/water solution.
In addition to 36 d of the 1/1 solution, 22.5 ml of water was further added to prepare a coating solution, which was coated so that the film thickness after drying was 10 μm.

The minimum transfer density (exposed area) and maximum transfer density (unexposed area) one day after Fresh were as shown in Table 1.
The values in Table 1 above, that is, the R density change at the highest density area, indicate the scale of fading of the Cyan color image, and the B density change is
This shows an increase in yellow stain (mainly due to the oxidation product of the color developing agent), and the change in R density in the lowest density area is mainly due to the increase in cyan concentration caused by post-transfer (oxygen contained in the air or water). The amount of increase in cyan dye caused by the coupling between the color developing agent and the coupler oxidized by
Yellow stain (mainly oxidation products of color developing agents)
shows an increase in

Therefore, as can be seen from Table 1 above, the image-receiving elements B and C containing the compounds according to the present invention showed less fading of the cyan dye image formed than type A, less post-transfer, and
The amount of yellow stain produced is also small. From this, it was revealed that addition of the compound of the present invention significantly improved fading of color images, prevention of post-transfer, and increase in yellow stain.
