Abstract

PURPOSE:To obtain stable photographic performance when an internal latent image type sensitive material for direct positive and a negative type sensitive material are developed with a common developing soln., by uniformly exposing the internal latent image type sensitive material during development and adding polyalkyleneimine or the like to the developing soln. CONSTITUTION:An internal latent image type sensitive material for direct positive and a negative type sensitive material are developed with a common developing soln. in an automatic developing apparatus capable of controlling uniform exposure so that uniform exposure is carried out only when the internal latent image type sensitive material is introduced into a development tank 7. Since the developing soln. contains polyalkyleneimine or alkanolamine, the oxidation coloring of a color developing agent is inhibited, the production of a component having absorption at a specified wavelength can be prevented to ensure broad absorption and a color change due to secondary reversal exposure can be reduced. Thus, stable photographic performance is obtd.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an internal latent image type direct positive silver halide photographic material $4 (hereinafter referred to as an internal layer type direct positive photographic material) and a negative type silver halide photographic material. The present invention relates to a development method in which a photosensitive material (hereinafter referred to as a negative photosensitive material) is processed with a common developer.

[Background of the Invention] Except for special methods, there are no methods used to create positive images using inner layer type direct positive light-sensitive materials.

Considering their practical usefulness, they can be divided into two main types.

One type uses a silver halide emulsion that has been fogged in advance and uses solarization or the Burschel effect to destroy fog nuclei (latent images) in exposed areas, thereby obtaining a positive image after development. .

Another embodiment uses an internal latent image type silver halide emulsion that is not fogged, and performs surface development after or while performing fogging treatment after image exposure to obtain a positive image.

What is the internal latent image type silver halide emulsion mentioned above?

It refers to a silver halide photographic emulsion that has photosensitive nuclei mainly inside silver halide grains, and a latent image is formed inside the grains when exposed to light.

This latter type of method generally has higher sensitivity than the former type of method and is suitable for image formation requiring high sensitivity, and the present invention relates to this latter type of method. .

Various techniques are known in this technical field. For example, U.S. Pat. No. 2.592.250;
, No. 468,957, No. 2,497,875, No. 2.
No. 588,982, No. 3,781,288, No. 3.
The main methods are those described in No. 7F31,278, No. 3,798,577, and Fukoku Patent No. 1,151,383, and using these methods, it is relatively easy to use as a direct positive type. Highly sensitive photographic materials can be made.

Although it cannot be said that a clear explanation has been given regarding the details of the direct positive image formation mechanism, for example, the theory of the photographic process J by Mies and James,
of the Pbotographic Proc
eSs) 3rd edition, page 161, you can understand to some extent the process by which a positive image is formed by the "desensitizing effect due to internal latent images" and the like.

In other words, fog nuclei are selectively generated only on the surface of unexposed silver halide grains due to the surface desensitization effect caused by so-called internal h' generated inside the silver halide grains by the first image exposure, and then It is believed that a photographic image is formed in the unexposed areas by normal development.

As mentioned above, as a means of selectively generating fogging nuclei, there is a method called "chemical fogging" in which fogging is performed using a chemical such as a fogging agent, and a method called "optical fogging" in which the entire surface is exposed to light. There is a known method of covering the skin with a mask.

By the way, when processing internal layer type direct positive photosensitive materials in a photo processing laboratory, a processing line exclusively for internal layer type direct positive photosensitive materials is set up separately from the conventional processing line for negative type photosensitive materials. is common.

For example, the negative-tone photosensitive material processing line has three types of equipment: an automatic developing machine for negative film, an automatic developing machine for negative paper, and an automatic printing machine, and on the other hand,
The S-type direct positive photosensitive material processing line consists of two types of equipment: a dedicated automatic printing device and a dedicated automatic developing machine.

Generally, a certain amount of work space is required around each of these devices, and the space necessary for adjusting the refill cock, correcting evaporation, replacing tank liquid, and refilling must also be secured around these devices. There must be,.

Therefore, the devices are distributed separately. However, it is necessary to ensure that the work space around each piece of equipment does not overlap, which may impede work in narrow spaces such as small-scale color photo labs. Reducing the size of developing machines has become an important issue.

Against this background, the present inventor continued research into processing Uchinuma-type direct positive-sensitive materials and negative-tone sensitive materials with a common developer, and first,
Attempts were made to process a direct positive light-sensitive material using a chemical fogging method and a negative-tone light-sensitive material with a developer having the same composition, but the occurrence of fog in the negative-tone light-sensitive material was significant. Developer solutions that commonly process internal direct positive and negative photosensitive materials require maintenance and control of the activity of the solution more than other processing solutions, and they are also generally heated to higher temperatures than other processing solutions. It was found that it is not easy to suppress the occurrence of fogging on the above-mentioned negative-tone sensitive material because the temperature must be set.

Therefore, 1. the present inventor investigated the light fogging method 6. In other words, when developing a direct-type positive-sensitive material, the light source is turned on to give full exposure to light; At this time, an attempt was made to develop both photosensitive materials in common by turning off the light source, but it was found that this light fogging method also had the following problems.

f2U, with the adoption of the light fogging method mentioned above, has it become possible to process inner layer type direct positive and negative type photosensitive materials with a common developer? 1. Even if the developer is replenished according to the type of each photosensitive material. Coloring of the liquid, especially yellow stone Buddha, may occur,
It was found that the color density of the yellow dye changed due to the filter effect of the secondary exposure, making it impossible to obtain stable photographic performance.

The reason for this is not necessarily clear, but it is thought that a butyric colored material having absorption at a specific wavelength is produced by the common processing of the internal direct positive sensitive material and the negative sensitive material. This problem would hardly be a problem if the internal latent type direct positive light-sensitive material and the negative-tone light-sensitive material were processed with separate developers.

[Object of the Invention] The object of the present invention is to develop a silver halide photographic light-sensitive material in which stable photographic properties can be obtained by developing an inner layer type direct positive light-sensitive material and a negative-tone light-sensitive material using a common developer. The purpose is to provide a processing method.

[Structure of the Invention] In order to achieve the above object, the present inventors have completed the present invention as a result of various studies, and have provided a method for developing a silver halide photographic material according to the present invention. The process involves developing an inner Ns-type direct positive light-sensitive material and a negative-tone light-sensitive material in the same developing bath, and when developing the inner layer-type direct positive light-sensitive material, the inner layer type direct positive light-sensitive material is completely coated. It has a step of exposing to light, and the developing solution is poly(alkyleneimine).
and/or alkanolamine.

[Action of the invention] The use of polyargyleneimine or alkanolamine not only reduces the oxidative coloring of the single color developing agent, but also prevents the formation of components that absorb specific wavelengths.
This results in a liquid sac color with broad absorption, and color fluctuations due to secondary inversion exposure are reduced. This allows P! Fluctuations in yellow dye density due to liquid sac color, which did not pose a problem when processing only 5-type direct printing positive light-sensitive materials, have been resolved, and stable photographic performance has been achieved.

In the present invention, an inner layer type direct positive light sensitive material and a negative tone sensitive material are developed with a common processing solution, and when the inner layer type direct positive light sensitive material is carried into the development processing layer, the entire surface is exposed to light. ,
When a negative-tone sensitive material is carried into the development layer, an automatic processor capable of controlling the entire surface exposure can be used so as not to expose the entire surface to light.

In the present invention, negative photosensitive materials mean color photographic paper, color negative film, color rehearsal film, and color rehearsal paper.

The neutralization process, stop-fixing process, post-hardening process, etc. may be performed.In these processes, instead of the color development process, a color developing agent or its precursor is contained in the photosensitive material, and then the photosensitive material is developed. An activator treatment step using an activator liquid may also be performed.

Representative examples of these processes are shown below.

In these treatments, as a final step (final bath), any one of (1) water washing treatment step, (2) water washing alternative stabilization treatment step, or (2) water washing treatment step and stabilization treatment step is performed.

The above compounds and other additives can be added to the stabilization tank as a concentrated liquid, or the above compounds and other additives may be added to the stabilizing liquid supplied to the stabilization tank and then stabilized. There are various methods, such as using it as a supply solution to the solution, or adding it to the pre-bath of the stabilization treatment process and making it present in the stabilization tank by including it in the silver halide photographic light-sensitive material to be processed. It may be added by any method.

The method for supplying the stabilizing liquid in the stabilization treatment process is multi-tank rpI.

Further, silver may be recovered by a known method not only from the above-mentioned stabilizing solution but also from a processing solution containing a soluble silver complex salt such as a fixing solution or a cool-white fixing solution.

In addition, if the above-mentioned stabilization treatment is performed, the water washing process is qualitatively unnecessary, so there is no need for piping equipment for water washing.
This has the advantage that the material itself can be easily installed in any location.

In addition to these treatments, there are methods in which the developer produced by color development is subjected to halogenation bleaching and then color development is performed again, and 4 yen BF! It may be processed using a developing method that increases the characteristics of the formed dye, such as various intensification processes (amplification processes) described in Sho 58-1548:19.

Each processing step is usually carried out by subjecting the photosensitive material to F2v1 in a processing solution, or using other methods such as a spray method in which the processing solution is supplied in the form of a spray, or by contacting it with a carrier impregnated with the processing solution. A web method, a method of performing viscous development processing, etc. may be used.

The internal latent image type silver halide emulsion used in the present invention is an emulsion having silver halide grains that mainly form a latent image inside the silver halide grains and has most of the photosensitive nuclei inside the grains. Silver halides such as silver bromide, silver chloride, silver iodochloride, silver 111 bromide, silver iodobromide, etc. are included. Silver chloride is particularly useful because it is a particle with a high development speed.

Silver chlorobromide, silver chloroiodobromide, and silver iodochloride are preferred.

It is preferable that the surface of each grain of the internal latent image type silver halide grains used in the present invention is not chemically sensitized, or even if it is sensitized, it is only to a small extent.

This method produces a crystal with a regular crystal shape and a small particle size. Almost uniform silver halide grains are obtained. After the ffl length, a conversion method may be used to change the halogen composition of the particles.

The silver halide emulsion of the present invention is prepared at the time of its manufacture.

If necessary, a silver halide solvent can be used to control the grain size of the silver halide grains, the shape and grain size distribution of the atom, and the growth rate of the grains.

The silver halide grains used in the silver halide emulsion of the present invention are formed using cadmium salt, zinc salt, or lead salt during the grain formation and/or grain growth process.

Metal ions are added using at least 19 selected from thallium salts, iridium salts (complex salts containing), rhodium salts (complex salts containing), and iron salts (complex salts containing). By placing it in an appropriate reducing atmosphere,
Reduction sensitizing nuclei can be provided inside the particles and/or on the particle surfaces.

Disclosure) It can be carried out based on the method described in No. 17643.

The silver halide grains used in the silver halide emulsion of the present invention are uniform silver halide within each grain! [Even if the grain has a power distribution, there may be core/shell grains (C) in which the silver halide acid supply is different between the inside of one grain and the surface layer.

The average grain size (grain size; defined below as "C") of the silver halide grains of the present invention is preferably 5 JL11 or less, and particularly preferably 3 gm or less.

The silver halide emulsion of the present invention may have any grain size distribution. An emulsion with a wide grain size distribution (referred to as a polydisperse emulsion) may be used, or an emulsion with a narrow grain size distribution (referred to as a monodisperse emulsion). When divided by the average grain size, the value is 0.20 or less, preferably n, ts or less. In the case of spherical silver halide, the diameter is 1. In the case of grains with a shape, the diameter is the diameter when the projected image is converted into a circular image of the same plane. May be used.

The silver halide emulsion of the present invention may be a mixture of two or more separately formed silver halide emulsions.

The silver halide emulsion of the present invention can be chemically sensitized by conventional methods. That is, a sulfur sensitization method, a selenium sensitization method, a reduction sensitization method, a sensitization method using gold or other noble metal compounds, etc. can be used alone or in combination.

The silver halide emulsion of the present invention can be optically sensitized to a desired wavelength range using dyes known as sensitizing dyes in the photographic industry. Can a sensitizing dye be used alone?
You may use two or more types in combination. Along with the sensitizing dye, the emulsion contains a dye that itself does not have a spectral sensitizing effect, or a supersensitizer, which is a compound that does not substantially absorb visible light and enhances the sensitizing effect of the sensitizing dye. Good too.

The silver halide emulsion of the present invention can be used to prevent fogging during the manufacturing process, storage, or photographic processing of light-sensitive materials.
Or during chemical ripening for the purpose of maintaining stable photographic performance,
At the end of chemical ripening and/or after chemical ripening and before coating the silver halide emulsion, compounds known in the photographic industry as antifoggants or stabilizers can be added.

Hydrophilic colloids such as gelatin derivatives, graft polymers of gelatin and other polymers, other proteins, sugar derivatives, cellulose derivatives, synthetic woody polymeric substances such as polymers or copolymers can also be used.

The photographic emulsion layer and other wood-philic colloid layers of the photosensitive material using the silver halide emulsion of the present invention (hereinafter referred to as the photosensitive material of the present invention) are formed by crosslinking binder (or protective colloid) molecules and forming a film. Hardening can be achieved by using one or more hardening agents that increase strength. The hardening agent can be added in an amount sufficient to harden the photosensitive material to the extent that it is not necessary to add the hardening agent to the processing solution, but it is also common to add the hardening agent to the processing solution.

A plasticizer may be added to the silver halide emulsion layer and/or other hydrophilic colloid layer of the light-sensitive material of the present invention for the purpose of increasing flexibility.

The photographic emulsion layer and other wood-philic colloid layers of the light-sensitive material of the present invention may contain a dispersion (latex) of a water-insoluble or sparingly soluble synthetic polymer for the purpose of improving one-dimensional stability.

In the emulsion layer of the light-sensitive material of the present invention, a dye is formed by a coupling reaction with an oxidized form of an aromatic primary amine developing agent (for example, p-phenylenediamine derivatives, aminophenol derivatives, etc.) during color development processing. A dye-forming coupler that forms is used. The dye-forming couplers are typically selected for each emulsion layer such that a dye is formed that absorbs light in the light-sensitive spectrum of the emulsion layer, with a yellow dye-forming coupler in the blue-sensitive emulsion layer and a dye-forming coupler in the blue-sensitive emulsion layer that absorbs light in the light-sensitive spectrum of the emulsion layer. A magenta dye-forming coupler is used in the sensitive emulsion layer, and a cyan color patch-forming coupler is used in the red-sensitive emulsion layer. However, depending on the purpose, silver halide color photographic materials may be produced using different combinations from the above.

These dye-forming couplers are 4-equivalent, in which 4 molecules of silver ions need to be reduced in order to form one molecule of dye, and 2-equivalent, in which only 2 silver ions need to be reduced. Either is fine. Dye-forming couplers can be used as development accelerators, bleach accelerators, developers, silver halide solvents, gJ colorants, hardeners, fogging agents, antifogging agents, and chemical sensitizers by coupling with oxidized forms of developing agents. Compounds that release photographically useful fragments can be included, such as spectral sensitizers, spectral sensitizers, and desensitizers. These dye-forming couplers may be combined with colored couplers that have a color correction effect, or DI couplers that release development inhibitors during development and improve image sharpness and image graininess. good. In this case, it is preferable that the dye formed from the DIR coupler is of the same type as the dye formed from the dye-forming coupler used in the same emulsion layer, but if the turbidity of one color is not noticeable, a different type of dye should be used. It may also be one that forms a pigment. In place of the DIR coupler, or in combination with the coupler, a DIR compound which undergoes a coupling reaction with the oxidized form of the developing agent to produce a colorless compound and at the same time releases a development inhibitor may be used.

A colorless coupler that undergoes a coupling reaction with an oxidized product of an aromatic primary amine developing agent, but does not form a color (;) can also be used in combination with a dye-forming coupler.

The sample work and sample (2) were cut into 82 mm widths, and for sample I, a color reversal film was photographed with a camera using ASAloo, and the positive obtained by color development was used to give a uniform image exposure using an auto color printer. Sample H was photographed with a color negative film ASAloo, and the negative obtained by color development processing was used to give a uniform image exposure using an auto color printer, and then using the automatic developing machine shown in Figure 1. Tested.

Note that No. 1r71 is a schematic diagram showing an example of an automatic developing machine that can be used in the processing of the present invention, and as shown in Figure 1, the automatic developing machine main body 1
is paper feed section 2. It consists of a photo processing section 3 and a drying section 4.

Silver halide photographic light-sensitive material 5, which is a sample according to this example
is formed into a roll and stored in a dark box 6. The silver halide photographic light-sensitive material 5 pulled out from the dark box 6 is developed in the photographic processing section 3 while being conveyed by a series of rotating pressure rollers.

In this embodiment, the photo processing section 3 has four processing tanks, namely:
Development processing tank 7, bleach-fixing processing tank 8 and stabilization tank 9.9'
It consists of The stabilizing tanks 9 and 9' are of a two-tank countercurrent type. Further, when an inner layer image type direct positive light-sensitive material is used as the silver halide photographic light-sensitive material 5, the exposure device 11 is detected by a sensor 13 and lights up a fluorescent lamp 12 to provide fogging exposure during development processing. When using negative photosensitive materials, avoid fogging exposure.

In the photographic processing section 3, the exposed silver halide photographic material 5 is processed for a predetermined time in each processing tank, and then sent to the drying section 4 where it is dried, and then cut into a predetermined length by a cutting member 14. It is cut and discharged from the device.

In the figure, 15 is a waste liquid storage section, and 16 is a replenishment liquid storage section.

The processing conditions are as follows.

Constant temperature: 32°C for 2 minutes (Note 1) The entire surface was exposed to light for 10 seconds after the sample entered the color developer.

A treatment solution having the following composition was used in the treatment area.

During ffi, the bleach-fix replenisher is replenished into the bleach-fix bath every 2.51 days per 4100 cm of photosensitive material. Further, the stable replenisher is replenished at a rate of 2.5 m per 101 crrr' of the photosensitive material. In processing line 1, sample ■ is added until the total amount of color developer replenisher or twice the amount of color developer tank (hereinafter referred to as 2
In processing line 2, sample ■ is subjected to two rounds i! In processing line 3, sample I 3rn' and sample 3m' were processed alternately for two consecutive rounds.

Samples 1 and 2, which were wedge-exposed to examine photographic properties, were processed at the beginning of each line and under the eaves in the middle (1st round and 2nd round).

Yellow (Y) and magenta (Y) of test sample 1 obtained by processing
Table 1 shows the maximum density of M) and cyan (C).

From Table 1, processing line 1.2 is trial 1■
In both cases, no density abnormality is observed as the continuous processing progresses, or in processing line 3, as the continuous processing progresses, the maximum dye density of yellow in the sample process decreases significantly. However, it can be seen that the addition of the compound of the present invention prevents such a decrease in the maximum yellow dye density.

Example 2 Using the sample material (2) used in Example 1, the same treatment as in Example 1 was performed to turn green, and evaluation was made in the same manner as in Example 1.

However, here, in place of the hydroxylamine sulfate in the color developer and color developer replenisher, hydroxylamines listed in Table 2 were added in the amounts listed in Table 2.

The additives and amounts added in the color developer and color developer replenisher were as shown in Table 2.

As is clear from Table 2, by using one of the various hydroxylamine derivatives in place of hydroxylamine sulfate, the maximum dye concentration of yellow in the sample process is greatly reduced. It can be seen that the decrease in maximum dye density is effectively prevented.
