Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide photographic light-sensitive material containing a coating agent in a hydrophilic colloid coating layer, and particularly to uneven development processing, contamination of processing solutions and contamination. Malfunction due to material (uneven drying,
The present invention relates to a silver halide photographic light-sensitive material (hereinafter referred to as a photographic light-sensitive material) that does not cause film stains and the like due to adhesion to a transport roller.

(Prior Art) As is well known, a photographic light-sensitive material is provided with several layers of hydrophilic colloid (usually gelatin) on a support such as a plastic film or paper. These layers have various functions such as an undercoat layer, an intermediate layer, a photosensitive layer and a protective layer, and each layer contains various inorganic or organic additives in order to satisfy those functions.

As described above, a general photographic light-sensitive material is formed from many hydrophilic organic colloid layers, and it is possible to apply these coating solutions in a thin layer uniformly and at high speed without coating failure such as cissing and uneven coating in the production thereof. Required. As a coating method, a continuous simultaneous multilayer coating method is often used in recent years.

The most difficult example of the coating process is the production of a color photographic light-sensitive material. In color photographic light-sensitive materials, color couplers,
Dissolve many water-insoluble additives such as UV absorbers and fluorescent whitening agents in high boiling point organic solvents such as phthalate ester compounds and phosphate ester compounds to prepare hydrophilic organic colloids, especially in gelatin solutions. It is used by being dispersed in the presence of a surfactant (so-called emulsified) and contained in the hydrophilic organic colloid layer. The use of a large amount of a surfactant as such an emulsifier makes it difficult to coat another hydrophilic organic colloid layer which is further coated on the hydrophilic organic colloid layer. When the amount of the emulsifier is reduced, the emulsified dispersion becomes unstable, causing aggregation and precipitation, and the photographic characteristics of the photographic light-sensitive material after coating become unstable.

Conventionally, various anionic surfactants have been used as coating aids for various coating liquids of photographic light-sensitive materials, and specific examples thereof are U.S. Pat.Nos. 2,240,476, 3,026,202, and 3,068,10.

No. 65, etc.

(Problems to be Solved by the Invention) However, when an anionic surfactant is used as a coating aid to further coat a colloidal solution such as gelatin on a colloidal layer such as gelatin, it is contained in gelatin. Since the solubility of the anionic surfactant is extremely reduced due to the alkaline earth metal ion such as calcium, when the anionic surfactant is added to the gelatin coating solution, it precipitates as a hydrated solid substance. There was a drawback that the coatability was significantly deteriorated.

Also, U.S. Pat. No. 3,850,642 used for antistatic,
A cationic antistatic agent such as a cationic surfactant disclosed in JP-A-57-146248 or the like, or a cationic polymer disclosed in JP-A-55-7763 or JP-A-54-18728,
When these anionic surfactants as coating aids are used together in the same light-sensitive material, if they are added to the same coating solution, insoluble (or hardly soluble) complex is formed between them and cissing occurs. There was a serious drawback that it would end up. On the other hand, even if both are added to different layers, they are dissolved in the processing solution when the photosensitive material is subjected to development processing, and both form an insoluble complex in the processing solution, resulting in uneven processing and development stain. There was a problem.

In recent years, it has been suggested to reduce the amount of washing water at the time of treatment from the viewpoints of environmental protection, water resources, cost, and simple and compact treatment equipment.

Further, a method of reducing the amount of treatment liquid by using a liquid to which various chemicals are added instead of a mere washing step with water (for example, JP-A Nos. 57-8542, 58-14834, 57-132146, and 58-132146). -186
No. 31, No. 59-184345, No. 57-197540, No. 58-134636
No.) As described above, when the amount of washing water is reduced or a chemical is used, the surfactant flowing out from the photographic light-sensitive material remains unevenly on the surface of the coating film and discolors with time, or when it is dispersed in the coating film. It is known that a so-called sweating phenomenon, which is caused by aggregation and coalescence of a boiling solvent, a coupler, etc., is promoted.

Further, in recent years, attempts have been made to reduce the amount of replenishing treatment liquid from the viewpoint of cost, but in this case as well, the ratio of the surfactant accumulated in the treatment liquid increases, and the anionic surface active agents disclosed so far are disclosed. When the photosensitive material using the agent is continuously processed, the formation of tar-like insoluble matter has been a problem.

Attempts have been made to thicken the treatment liquid in order to further shorten the treatment time, but again, the same problems as described above were encountered.

As a part of shortening and simplifying the processing time, a bleaching accelerator is added to the bleaching or bleach-fixing solution (JP-A-53-95630, 57-192953).
Japanese Patent Publication No. 54-12056 and US Pat. No. 4,552,834) are known.

However, it was found that an insoluble complex was formed between the bleaching accelerator and the anionic surfactant flowing out from the light-sensitive material to cause contamination of the processing solution, and its improvement has been desired.

On the other hand, recently, JP-A-60-76741 has been disclosed as a method for preventing contamination of a treatment liquid of an ethylene oxide nonionic surfactant used as an antistatic agent. The patent describes that anionic surfactants containing ethylene oxide groups in the molecule are effective. Certainly, this compound improves the treatment stain by the complex with the cationic compound and the treatment liquid stain of the ethylene oxide nonionic surfactant used together, as compared with the above-mentioned anionic surfactant.
However, it is not sufficient that any processing liquid does not cause processing contamination. For example, as mentioned above, in recent years, due to environmental protection, cost reduction, or simple and compact processing equipment, the processing solution is becoming thicker, the amount of replenishing processing solution is being reduced, and the processing solution is being rapidly processed. pollution,
The problem of stains on the photosensitive material due to adherence of contaminants to the transport roller has not been solved.

As described above, the occurrence of these problems may be caused by the properties of the surfactant itself used for each purpose or by the interaction with other coexisting additives.

Therefore, in order to solve these problems, it is considered most preferable to improve the individual surfactants used for each purpose, but in reality, it may impair the intended performance. There are many significant difficulties.

(Object of the Invention) A first object of the present invention is to apply a gelatin-containing solution or other hydrophilic colloid solution uniformly on a support such as film or paper or other photographic layer without cissing. To provide a photographic light-sensitive material.

A second object of the present invention is, without impairing the antistatic property,
An object of the present invention is to provide a photographic light-sensitive material which does not cause contamination of a developing solution and has no image unevenness.

(Means for Solving the Problems) These objects of the present invention are to provide a photographic material having at least one light-sensitive silver halide emulsion layer on a support in a silver halide emulsion layer or another hydrophilic colloid layer. Was achieved by incorporating a compound represented by the following general formula [I] into

Next, specific examples of the compound used in the present invention will be shown, but the invention is not limited thereto.

The compounds represented by the general formula [I] are characterized by having both an ethylene oxide group and a glycidol group in the molecule.

It is considered that the reason why the compound of the present invention does not cause contamination of the treatment liquid is that the solubility of the compound of the present invention is significantly improved even in the treatment liquid having high ionic strength due to the presence of the glycidol group. The ethylene oxide group is considered to be the reason why the compound of the present invention has good photographic properties.

Today, as mentioned above, the problem of processing solution contamination is becoming more serious as the composition of processing solutions changes, but various photographic additives, especially those with a structure like a surfactant, are processed by the film. Diffuses in the liquid and causes contamination of the processing liquid. For example, an ethylene oxide nonionic surfactant used as an antistatic agent is liable to contaminate the treatment liquid, but it is also possible to prevent the treatment liquid from being contaminated by using the compound of the present invention together.

For example, phthalic acid alkyl ester (dibutyl phthalate, dioctyl phthalate, etc.), phosphoric acid ester (diphenyl phosphonate, triphenyl phosphonate, tricresyl phosphonate, dioctyl butyl phosphonate), citric acid ester (eg acetyl) Tributyl citrate), benzoic acid esters (eg octyl benzoate), alkylamides (eg cyethyllaurylamide), fatty acid esters (eg dibutoxyethyl succinate, diethyl azelate), trimesic acid esters (eg tributyl trimesate) ), Or an organic solvent having a boiling point of about 30 ° C. to 150 ° C., for example, lower alkyl acetate such as ethyl acetate and butyl acetate, ethyl propionate, secondary butyl alcohol, methyl isobutyl ketone, β-ethoxide. After being dissolved in cyethyl acetate, methyl cellosolve acetate, etc., it is dispersed in a hydrophilic colloid. The high boiling point organic solvent and the low boiling point organic solvent may be mixed and used.

It is also possible to use a dispersion method using a polymer described in the above publication.

When the coupler has an acid group such as carboxylic acid or sulfonic acid, it is introduced into the hydrophilic colloid as an alkaline aqueous solution.

A known anti-fading agent can be used in the photographic light-sensitive material of the present invention. Known anti-fading agents include hydroquinone derivatives, gallic acid derivatives, p-alkoxyphenols, p-oxyphenol derivatives and bisphenols.

The above-mentioned various additives are used in the light-sensitive material of the present technology, but various additives other than the above can be used depending on the purpose.

These additives are described in more detail in Research Disclosure No. 17643 (December 1978) and No. 18716 (1979).
(November, 2013), and the relevant parts are summarized in the table below.

For the light-sensitive material of the present invention, various known quaternary ammonium salt (or phosphonium salt) polymers can be used as the polymers that provide cation sites in the fixing solution. The quaternary ammonium salt (or phosphonium salt) polymer is widely known as a mordant polymer or an antistatic polymer in the following publications.

Preferred polymers are listed below.

Compound example The amount of the polymer that provides cation sites in the fixing solution is 0.1 or more, preferably 0.3 to 100, and more preferably 0.5 to 30, as a unit of cation sites per 1 mol of the total iodine in the light-sensitive material.

The polymer providing a cation site can be added to the light-sensitive layer or the non-light-sensitive layer, but it is preferable to add a non-light-sensitive layer between the light-sensitive layer and the support. It is particularly preferable when the additive layer is an undercoat layer. Among the polymers that provide cation sites, those that have a high ability to capture halogen ions are preferable.

The polymer which provides a cationic site that can be contained in the light-sensitive material of the present invention can also be used as a substance which mordantes an anti-halation or anti-irradiation dye. In this case, it is preferable to use an anionic dye that is decolorized in the developing-fixing-water washing process. Further, in a double-sided X-ray film for direct medical treatment, it is possible to cut the crossover light and improve the sharpness by mordanting a decolorizing dye on the lower side of the emulsion layer. The addition of the cation site-providing polymer and the anionic dye produces particularly preferable effects.

Hereinafter, preferable dyes that can be used in the light-sensitive material of the present invention will be described.

Representative dyes are shown below, but the present invention is not limited thereto.

Various exposing means can be used for the light-sensitive material of the present invention. Any light source that emits radiation corresponding to the sensitivity wavelength of the photosensitive material can be used as the illumination light source or the writing light source. Flash light sources such as natural light (sunlight), incandescent lamps, halogen atom-sealed lamps, mercury lamps, fluorescent lamps and strobes or metal burning flash bulbs are common. A gas, a dye solution or a semiconductor laser, a light emitting diode, or a plasma light source which emits light in a wavelength range from ultraviolet to infrared can also be used as the recording light source. In addition, a linear line is formed in a micro-scatter array using a phosphor screen (CRT, etc.) emitted from a phosphor excited by an electron beam, liquid crystal (LCD), lanthanum-doped lead titan zirconate (PLZT), etc. Alternatively, an exposure means combining a planar light source can also be used. If necessary, the spectral distribution used for exposure can be adjusted with a color filter.

For the photographic processing of the light-sensitive material of the present invention, any known method can be used, and known processing solutions can be used. The treatment temperature is usually selected from 18 ° C to 50 ° C, but may be lower than 18 ° C or higher than 50 ° C. Depending on the purpose, either a development process for forming a silver image (black and white photographic process) or a color photographic process including a development process for forming a dye image can be applied.

The black-and-white developing solution contains known developing agents such as dihydroxybenzenes (eg hydroquinone), 3-pyrazolidones (eg 1-phenyl-3-pyrazolidone), aminophenols (eg N-methyl-p-aminophenol) and the like. They can be used alone or in combination.

Color developers generally consist of an alkaline aqueous solution containing a color developing agent. Color developing agents are known primary aromatic amine developers such as phenylenediamines (eg 4-
Amino-N, N-diethylaniline, 3-methyl-4-amino-N, N-diethylaniline, 4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-
4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β
-Methanesulfoamidoethylaniline, 4-amino-3
-Methyl-N-ethyl-N-β-methoxyethylaniline and the like) can be used.

If necessary, any development accelerator can be added to the color developing solution. However, it is preferable that the color developing solution of the present invention does not substantially contain benzyl alcohol from the viewpoints of pollution, liquid preparation and fog prevention. Here, "substantially free of benzyl alcohol" means that the amount of benzyl alcohol per color developer is 2 ml or less. Preferably, it contains no benzyl alcohol.

Further, in the color developing solution, other preservatives such as sodium sulfite, potassium sulfite, sodium bisulfite, potassium bisulfite, sodium metasulfite, potassium metasulfite, and the like, and a carbonyl sulfite adduct are added as necessary. It can be added. Additives to these color developers are 0 g to 20 g / l, preferably 0 g to 5 g / l, and if the preservative property of the color developers is maintained, a small number of methods are preferable. In order to improve the color developability, it is preferable that the sulfite ion is not substantially contained, and more specifically, it is 0.5 g / l or less, more preferably 0.2 g / l or less in terms of sodium sulfite.

In addition, LFA Messon's "Photographic Processing Chemistry", published by Focal Press (1966)

Nos. 4,483,933, and JP-A-48-64933 may be used.

The developer may be a development inhibitor such as a pH buffer such as an alkali metal sulfite, a carbonate, a borate and a phosphate, a bromide, an iodide or an organic antifoggant other than the compound of the present invention, or a fog. Inhibitors and the like can be included. If necessary, a water softener, a preservative such as hydroxylamine, an organic solution such as benzyl alcohol or diethylene glycol, a polyethylene glycol, a quaternary ammonium salt, a development accelerator such as amines, a dye-forming coupler, a competitive coupler, Fogging agents such as sodium boron hydride, auxiliary developing agents such as 1-phenyl-3-pyrazolidone, tackifiers, polycarboxylic acid type chelating agents described in U.S. Pat. No. 4,083,723, West German publication (OLS) 2,62
The antioxidant described in No. 2,950 may be included.

When color photographic processing is performed, the photographic light-sensitive material after color development is usually bleached. The bleaching process may be performed simultaneously with the fixing process or may be performed individually. As the bleaching agent, for example, compounds of polyvalent metals such as iron (III), cobalt (III), chromium (VI) and copper (II), peracids, quinones, nitroso compounds and the like are used. For example, organic compounds such as phenyl cyanide compounds, dichromates, iron (III) or cobalt (III), for example, aminopolycarboxylic acids such as ethylenediaminetetraacetic acid, nitrilotriacetic acid, 1,3-diamino-2-propanoltetraacetic acid or quinic acid. Complex salts of organic acids such as acids, tartaric acid and malic acid; persulfates, permanganates, nitrosphenol and the like can be used. Of these, potassium ferrocyanide, sodium iron (III) ethylenediaminetetraacetate and ammonium iron (III) ethylenediaminetetraacetate are particularly useful. The ethylenediaminetetraacetic acid iron (III) complex salt is useful both in a stand-alone bleaching solution and in a one-bath bleach-fixing solution.

For bleaching or bleach-fixing solutions, U.S. Pat.
Various additives can be added in addition to the bleaching accelerators described in 3,241,966, JP-B-45-8506, JP-B-45-8836, and the thiol compounds described in JP-A-53-65732.

The washing process may be carried out in one tank, but in most cases it is 2
It is carried out by a multi-stage countercurrent washing method of more than a tank. The amount of water in the washing step can be arbitrarily set according to the type and purpose of the color light-sensitive material. For example, Journal of the Motion Picture and Television Engineering 64: 248-253 (1955 (May issue) “Water Florents in Immersion Watering of Motion Picture Film” (Water Flow Rat)
es in Immersion-Washing of Motion Picture Film, S.
It can also be calculated by the method described in R. Goldwasser).

When reducing the amount of water to be washed, the occurrence of bacteria and mold becomes a problem, but as a reaction therefor, washing water with reduced calcium and magnesium described in Japanese Patent Application No. 61-131632, a bactericidal agent and an antibacterial agent. , For example, the Journal of
Antibacterial and Amphuningal Ages (J.Antibact.Antifug, Agents) vol.11, No.5, p
207 to 223 (1983) and compounds described in Hiroshi Horiguchi, "Chemistry of Antibacterial and Antifungal Chemistry") can be added. Further, as a water softener, ethylenediaminetetraacetic acid, various hardeners or the like can be added as required. Or by West Photographic
Science and Engineering Magazine (Phot.Sci.E
ng.), Vol. 6, pp. 344-359 (1965), etc., may be added. It is particularly effective to add a chelating agent or a bactericide / antifungal agent.

The water washing step is a multi-stage countercurrent water washing of two or more layers (for example, 2 to 9).
It is also possible to reduce the amount of washing water by using a tank). Further, instead of the water washing step, a multistage countercurrent water washing treatment step as described in JP-A-57-8543 may be carried out. Various compounds are added to the washing bath for the purpose of stabilizing the image. For example, various buffers (eg borate, metaborate, borax, phosphate, carbonate, potassium hydroxide, sodium hydroxide, aqueous ammonia) for adjusting the membrane pH (eg pH 3 to 9), Representative examples include aldehydes such as monocarboxylic acids, dicarboxylic acids, and polycarboxylic acids used in combination) and formalin. Other chelating agents (inorganic phosphoric acid, aminopolycarboxylic acid, organic phosphonic acid, aminopolyphosphonic acid, phosphonocarboxylic acid, etc.), bactericides (thiazole-based, isothiazole-based, halogenated phenol, sulfanilamide, benzo) Various additives such as triazole), optical brighteners and hardeners may be used, and two or more kinds of the same or different target compounds may be used in combination.

Further, it is preferable to add various ammonium salts such as ammonium chloride, ammonium nitrate, ammonium sulfate, ammonium phosphate, ammonium sulfite, and ammonium thiosulfate as a film pH adjuster after the treatment in order to improve the image storability.

Immediately after the washing step, a stabilizing bath containing a draining agent and formalin can be used. When processing a light-sensitive material using a 2-equivalent magenta coupler, the formalin may be removed or the stabilizing bath itself may not be used.

The washing time of the light-sensitive material of the present invention varies depending on the processing conditions, but is usually 20 seconds to 10 minutes, and preferably 20 seconds to 5 minutes.
