DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a silver halide photographic material and a processing method thereof, and a dispersion of fine particles formed from fibers.

[0002]

2. Description of the Related Art The surface of a silver halide photographic light-sensitive material comes into contact with an object having various shapes and properties during the production and use of the silver halide photographic light-sensitive material. For example,
Coating of silver halide emulsion layer-winding step, cutting processing step,
High-speed rotating transport rolls, cutting blades, roll cutters, suction cups in the packaging process, films in packaging, film cameras In contact with a transport roll or nip roll, a suction cup of a photographing machine, a transport adhesive tape of a photographing machine, a roll or nip roll of a developing machine, a drying heat roll, or the like.

[0003] Even if these silver halide photographic materials are exposed to contact, desorption, peeling, and pressure, which can be called severe, scratches, scratches, crackling, peeling, damage due to static electricity, various defects generated after development, etc. Silver halide photographic light-sensitive materials are required to be free from the occurrence of silver halide photographic light-sensitive materials. In order to prevent the occurrence of these defects, for example, a protective layer has been provided on the outermost layer (outermost layer) of the silver halide emulsion layer, and a matting agent has been contained therein.

[0004] Matting agents used for this purpose are described in a large number of documents, for example, JP-B-39-5513 and JP-B-43-22881, German Patent No. 2

And JP-A-5-188514.

The outermost layer of a silver halide photographic material has
In addition to the above matting agents, various compounds are added to provide functions according to the purpose. For example, a water-soluble polymer is added for the purpose of providing rapid processing, a hydrophilic low-molecular substance is added for the purpose of preventing dry fog, and a nonionic surfactant charge control agent is added for the purpose of preventing or controlling static. As the amount of addition of these substances increases, the amount of gelatin used as a binder decreases. When the amount of the binder is reduced and the proportion of the binder in the layer is reduced, various effects are exerted on the performance of the silver halide photographic material.

Further, in recent years, it has been demanded that each constituent layer of the silver halide photographic light-sensitive material be made thinner for the purpose of improving the processing speed. As the constituent layers become thinner as described above, the outermost layer also needs to be made thinner, and the amount of binder in the outermost layer further decreases, and the stability of the matting agent becomes poor. In particular, when the speed of development processing is increased and handling becomes more severe, it is required to further increase the stability of the matting agent in the outermost layer.

[0007] In response to these requirements, conventionally used spherical plastic matting agents such as polymer beads having no affinity for the binder have become intolerable. Therefore, the use of a matting agent composed of gelatin particles hardened with a hardening agent as the matting agent is described in, for example, JP-A-4-335340 and JP-A-5-18.
No. 8514, Japanese Patent Application Laid-Open No. Hei 8-21556, Belgian Patent No. 841,956, British Patent No. 1,
No. 532,708, U.S. Pat. No. 4,148,94.
No. 3 has been proposed.

[0008] However, although the hardened gelatin particle matting agent has an affinity for the binder gelatin, the swelling state is different from the binder gelatin, and the swollen gelatin matting agent loses hardness and develops tackiness, and is developed at high speed. In the case of processing, it has been found that there is a disadvantage that the matting agent is apt to fall off due to contact with a roll or the like of a developing machine.

[0009]

Accordingly, the first aspect of the present invention is as follows.
An object of the present invention is to provide a silver halide photographic light-sensitive material which is hard to fall off a matting agent even under severe development processing conditions and severe handling conditions, is excellent in stickiness and devitrification, and a processing method therefor.

Hereinafter, the present invention will be described in detail. The fiber in the present invention includes a fibrous substance in the form of a fiber in addition to the fiber. As the fiber used for obtaining the fine particles formed from the fiber of the present invention, most fibers can be used as long as they are natural fibers, regenerated fibers, semi-synthetic fibers or synthetic fibers. In addition, fibrous substances of outer hairs and leather of animals are also included.

[0014] Fibers generally referred to as natural fibers include:
There are plant fibers and animal fibers. As the plant fibers, any natural cellulose fibers obtained from wood fibers, stem stem fibers, vein fibers, bast fibers, seed fibers and the like can be used. Examples of these fibers include cotton, linter, hemp, mulberry, mulberry, mitsumata and the like.

The animal fibers include silk and silk (fibroin) fibers from silkworms and wild silkworms (eg, cocoons, tussah cocoons, and eri silkworms), wool, and cashmere hair fibers.
Fibers from animal hair such as camel hair fibers, goat hair fibers, and alpaca hair fibers, and fibrous substances forming animal leather are also included.

Examples of the recycled fiber include rayon fiber, cupra fiber (trade name of Asahi Kasei Co., Ltd.), Tencel or Dexel fiber (trade name of Coatles Co., Ltd.) and the like.

Examples of the semi-synthetic fibers include cellulose acylate and cellulose ether fibers. Examples of the cellulose acylate fibers include cellulose triacetate and cellulose triacetate.
Fibers made from cellulose diacetate, cellulose acetate propionate, cellulose acetate butyrate, cellulose benzoate, cellulose acetate benzoate, and the like can be given.

As synthetic fibers, vinylon, nylon,
Examples include polyester fibers having a hydrophilic group, polyimides or polyamides having a hydrophilic group, and polyacryl fibers having a hydrophilic group. The examples of fibers mentioned above do not limit the fibers used in the present invention.

Particularly preferred fibers for use in the present invention are silk and silk fibers, more preferably silk fibers from silkworms having pure white luster. Silk fiber (fibroin)
Has a unique triangular cross-sectional shape, and the fiber itself has a very high affinity for gelatin, and it is moderately easy to fix in a gelatin binder, is white, and has excellent water absorption and moisture release properties It is most preferably used because it can be easily obtained as silk powder. Of course, other silks are also preferably used.

The fibers of animal hair such as wool are used as fibers after degreasing or decoloring. Further, a fibrous substance forming a skin, that is, a collagen fiber is also preferably used. Collagen fiber is a precursor of gelatin for the binder used in the present invention and has an excellent affinity for gelatin. As animal species, those of herbivores such as cows, pigs, sheep, horses, camels and deer are preferred.

For synthetic fibers, semi-synthetic fibers or regenerated fibers, triangular, square, polygonal, star-shaped, irregular shapes and hollow fibers can be obtained by devising the cross-sectional shape of the nozzle of the spinning die. Fibers which are said to have a good hand when formed into yarn or woven fabric are preferred in the present invention. Also,
The surface of the fiber can be made scaly like wool, and such a material is preferable because it can be easily fixed in a binder.

The fine particles formed from the fiber of the present invention have a moisture absorption of 3.0 to 20% at 20 ° C. and 65% RH, or
It is preferably 8 to 40% at 20 ° C. and 95% RH, and preferably has a moisture absorption similar to that of the binder because it is easily compatible with the binder and hardly desorbs. Note that the hygroscopicity in the present invention is the same as that of a normal sample. From the weight A of the sample in the atmosphere and the dry weight B of the sample, the hygroscopicity (%) = {(AB) / B} × 100 Is calculated.

The fine particles formed from the fiber of the present invention are prepared as follows. First, if there is fat contained in the fiber, perform degreasing with an alkali or other degreasing agent,
When coloring is extreme, bleaching is performed with a bleaching agent or the like.

It is also important to take out the fiber, and the method of taking out the fiber differs depending on the fiber source. For example, in the case of silk, a cocoon is boiled to find a thread of one cocoon and to remove it in the same manner as a method of removing raw silk from a normal cocoon. Since the fiber in the cocoon state is composed of two fibroins (fibers) and sericin wrapping the fibroin, the fibroin (fibers) is taken out by dissolving and removing sericin while boiling with hot soapy water.

To remove the fibers from the hide, the hide is subjected to lime treatment or acid treatment to separate collagen fibers. The treated skin can be used as it is.

The hair protein is made of keratin and has a fibrous form, and can be used as it is. The hair is preferably as thin as possible, soft and white, and can be crushed and used as it is. As described above, it is preferable to perform bleaching with a bleaching agent or degreasing with an alkali or the like.

For natural fibers other than cotton and linter, the raw material is immersed in water or hot water, and the skin is separated and taken out while tapping, and bleached as necessary, or the resin content contained in bark is treated with water for a long time. Exposure or removal.

Next, the fineness of the silk fiber of the present invention will be described. Micronization of silk can be performed by the method described in JP-A-8-113714. A first crushing means for crushing silk fibroin into coarse powder by dry mechanical crushing means, a second crushing means for crushing silk fibroin coarse powder to fine powder by dry mechanical crushing means, and a fine powder of silk fibroin. Is pulverized by a dry mechanical pulverizing means into a fine powder having an average particle diameter of 10 μm or less to be finely divided. The average particle size of the coarse powder is about 100 μm.
As the mechanical pulverizing means used in the coarse powder step, any means can be used as long as it can be pulverized, but a rotary mill is preferable. As the second mechanical pulverizing means, a ball mill is preferable, and as the third mechanical means, a jet mill is preferable. It is preferable to make the particles finer in this manner as a means for forming fine particles. The average particle size was measured using a laser rotary analyzer (SK LAZAR PRO 7 manufactured by Seishin Enterprise Co., Ltd.) using methanol as a dispersion medium.
000S (trade name)).

In addition to the above, a vibrating mill, a planetary mill, a sand mill, a colloid mill and the like can be used as the means for forming fine particles. The number of stages of these mechanical crushing means is not limited to three, and may be any number.

It is preferable to perform the β-treatment after any of the mechanical pulverizing means. However, the β-treatment may be performed twice or more. It is generally said that fibroin has a β structure as a secondary structure. However, β-treatment means that the ratio of the β structure is further increased, and fibroin powder is converted into an organic solvent such as methanol, ethanol, or acetone. By immersing in, the β structure can be effectively increased. By performing this treatment, crystallization can be increased to 70% or more, and dispersibility can be improved. As a result, it is possible to enhance the properties of silk such as moisture absorption, moisture release, antistatic performance, and moisture permeability.

Other fibers can be made into fine particles in the same manner as the above-mentioned fine silk fibers except for β-formation. The average particle size of the fine particles formed from the fibers obtained by the above-mentioned fine particle forming method is 20 μm or less, preferably 0.4 to 10 μm. The particle size can be controlled by adjusting the pulverizing time and strength in each of the three stages of mechanical pulverizing means and the number of stages of the pulverizing means, and by appropriately using these three stages of mechanical pulverizing means. Can do it. In the silver halide photographic light-sensitive material of the present invention, the amount of fine particles formed from fibers is preferably from 1 to 2000 mg / m ² , and from the viewpoint of devitrification, it is from 5 to 1500 mg / m ^2.

Normally, when such various additives are used together with the matting agent, these additives may affect the dropout of the matting agent during high-speed development processing.
The fine particles formed from the fiber of the present invention are hardly affected by the fine particles, and additives which have conventionally been difficult to use together can be used, and the range of designing silver halide photographic materials can be widened.

The surface of the silver halide photographic material containing fine particles formed from the fiber of the present invention can be observed and measured by a usual method for measuring surface roughness. These observation and measurement means include, for example, an optical microscope, a scanning electron microscope, and a surface roughness meter.
