Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention provides at least one layer of photosensitive silver halide emulsion scrap on one side of a support, and the emulsion layer side of the support is A silver halide photoprinter with a layer made of a cationic polymer (antistatic agent) on the opposite side (back side).
It relates to photosensitive materials (hereinafter simply referred to as photographic light-sensitive materials or light-sensitive materials).

[Prior Art] Photographic light-sensitive materials are generally made by coating cellulose triacetate, polyethylene terephthalate, paper, or paper coated on both sides with polyethylene terephthalate on one or both sides of a support, either directly or through a subbing layer. A silver halide photographic emulsion layer and, if necessary, each layer such as an intermediate layer, a protective layer, a filter layer, an antistatic layer, an antihalation layer, etc. are combined and provided in a quasi-sequential manner. These layers generally consist of a hydrophilic binder such as gelatin. Examples of photographic materials that have 4F photographic emulsion layers on both sides of a support include direct X-ray film, but most other photographic materials have a photographic emulsion layer on only one side of the support. There is. Therefore, in the latter case, there is a surface on which the photographic emulsion layer is not coated, that is, the surface of the support, and this is generally referred to in the art as the "r-back surface" of the photographic light-sensitive material.

It is known that an anti-electrostatic layer is provided on the back of the above-mentioned photographic light-sensitive material in order to prevent uneven exposure due to static electricity generated during the manufacturing process or during use. For example, JP-A No. 49-121523, JP-A No. 50-54672, JP-A No. 53-45231, or JP-A No. 53-92125.
Cationic polymers are described as useful antistatic agents in various publications such as No.

On the other hand, photographic materials require various devices, machines, cameras, etc. during manufacturing processes such as coating, drying, and processing, as well as during handling such as winding, rewinding, and transportation during photographing, developing, printing, and projection. between the adhesive part of the photosensitive material and
Alternatively, contact friction with adhering substances such as dust and fiber waste often causes significant adverse effects. In particular, since the bag often comes into direct contact with various types of equipment, it is prone to scratches and abrasions, deterioration of the drive performance of photosensitive materials in cameras and other machines, and generation of film waste. These scratches appear as reflections on the image surface during printing or imaging, and are a serious defect in practical use. Also,
Recently, due to the expansion of the use and processing methods for photosensitive materials such as high-speed coating, rapid imaging, and rapid processing, and the diversification of usage environments such as high-temperature and high-humidity atmospheres, the use of photosensitive materials has become more difficult than in the past. As a result of being subjected to harsh handling, scratches and deterioration of cantering performance are becoming more likely to occur. Therefore, there is a need for a photosensitive material that has a surface quality with high slipperiness and scratch resistance that can sufficiently withstand even such harsh conditions.

Conventionally, a method of providing a surface layer containing a slip agent has been used as a means to improve the slip properties and scratch resistance of the back surface of photographic light-sensitive materials. As a slip agent, for example, Japanese Patent Publication No. 53-29
Polyorganosiloxane as disclosed in U.S. Pat. No. 2, higher fatty acid amide as disclosed in U.S. Pat.
1, fatty acid esters as disclosed in British Patent No. 1,320,564, and higher fatty acid metal salts as disclosed in U.S. Pat. No. 3,933,516. Are known.

During the manufacturing process, after providing the surface,
It has been found that once rolled up and stored, the slip agent contained in the surface layer migrates to the side of the support where the emulsion layer is provided, resulting in problems such as uneven emulsion coating. Ta.

Pentaazaindenes, etc.;
Many compounds known as antifoggants or stabilizers can be added, such as benzenethiosulfonic acid, benzenesulfinic acid, benzenesulfonic acid amide, and the like.

As the binder or protective colloid that can be used in the emulsion layer of the photographic material of the present invention, it is advantageous to use gelatin, but other hydrophilic colloids can also be used. For example, gelatin derivatives, graft polymers of gelatin and other polymers, flea white matter such as albumin and casein; cellulose derivatives such as hydroxyethyl cellulose, carboxymethyl cellulose, and cellulose sulfate esters; sugar derivatives such as sodium alginate and starch derivatives; Various synthetic wood-philic polymers such as single or copolymers of vinyl alcohol, polyvinyl alcohol partial acetal, polyN-vinylpyrrolidone, polyacrylic acid, polymethacrylic acid, polyacrylamide, polyvinylimidazole, polyvinylvirazole, etc. can be used.

-propanol, 1,2-bis(vinylsulfonylacetamido)ethane, bis(vinylsulfonylmethyl)ether, vinyl polymers frequently having vinylsulfonyl groups, etc.) are preferred because they have a fast curing speed and provide stable photographic properties. N-carbamoylpyridinium salts ((l-morpholinocarbonyl-3-pyridinio)methanesulfonate, etc.) and haloamidinium salts (1-
(1-chloro-1-pyridinomethylene) pyrrolidinium 2-naphthalenesulfonate, etc.) is also excellent in its fast curing speed.

Emulsion layers, auxiliary layers (hydrophilic colloid layers), etc. of photosensitive materials contain various coating aids, antistatic properties, slipperiness improvement, emulsification dispersion, adhesion prevention, and photographic property improvement (e.g. development acceleration, high contrast, sensitization), etc. One or more surfactants may be included for this purpose.

The light-sensitive material may contain water-soluble dyes in the hydrophilic colloid layer as filter dyes or for various purposes such as irradiation or antihalation. As such dyes, 5-oxonol dyes, hekioxonol dyes, steel dyes, merocyanine dyes, anthraquinone dyes, and azo dyes are preferably used, and in addition, cyanine dyes, azomethine dyes, triarylmethane dyes, and phthalocyanine dyes are also used. . An oil-soluble dye can also be emulsified by an oil-in-ice dispersion method and added to the hydrophilic colloid layer.

The photographic material of the present invention can be used as a multilayer, multicolor photographic material in which the support L has at least two different spectral sensitivities. Multilayer natural color photographic materials usually have at least one red-sensitive emulsion layer, one green-sensitive emulsion layer and one a-sensitive emulsion layer on the support L. The arrangement order of these layers can be arbitrarily selected as required. A preferred layer arrangement is, from the support side, in the order of red sensitivity, U sensitivity and blue sensitivity, the order of a sensitive layer, green sensitive layer and red sensitive layer, or the order of blue sensitivity, red sensitivity and green sensitivity. Further, any emulsion layer manufactured by the same company may be composed of two or more emulsion layers having different sensitivities to improve the attained sensitivity, or a three-layer composition may be used to further improve the graininess. Furthermore, a non-photosensitive layer may be present between two or more emulsion layers having the same color sensitivity. A configuration may also be adopted in which emulsion layers of different color sensitivity are inserted between emulsion layers of the same color sensitivity. It is also possible to improve the sensitivity by providing a reflective layer such as fine-grain silver halide under the high-sensitivity layer, particularly under the high-sensitivity blue-sensitive layer.

Generally, the red-sensitive emulsion layer contains a cyan-forming coupler, the five-edge-sensitive emulsion layer contains a magenta-forming coupler, and the R-sensitive emulsion layer contains a yellow-forming coupler, but different combinations may be used depending on the case. For example, an infrared-sensitive layer may be combined to provide pseudo-color image quality or semiconductor laser exposure.

The silver halide photographic emulsion layer is made of a coating solution in which the silver halide emulsion and hydrophilic colloids are dissolved or separated.
The photosensitive liquid may be prepared by preparing a photosensitive liquid, coating the coating liquid on the support described in step 11, and drying. Also,
Any hydrophilic colloid layer can be applied in a similar manner to have the desired function.

Various known coating methods such as dip coating, roller coating, curtain coating, and extrusion coating can be used to coat the photographic emulsion layer and other hydrophilic colloid layers. U.S. Pat. No. 2,681,2 as appropriate.
No. 94, No. 2,761,791, No. 3,526,
