Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides at least one light-sensitive silver halide emulsion layer on one side of a support. and a silver halide photographic light-sensitive material (hereinafter referred to simply as "F") having a layer (Teiden vj+L W ) made of a thionic polymer on the side (bark surface) opposite to the emulsion layer side of the support. (referred to as photographic light-sensitive materials or light-sensitive materials).

[Prior Art] Photographic light-sensitive materials are generally prepared by forming a coating layer directly or on one or both sides of a support such as cellulose triacetate, polyethylene terephthalate, paper, or paper coated with polyethylene terephthalate. Through the halogenated plate photographic emulsion and, if necessary, the middle 111 layer,
Protective layer: A filter layer, antistatic layer, anti-static layer, anti/\ration waste, etc., are combined and applied in various ways. These layers generally consist of a woody binder such as gelatin. As the photosensitive material t1 having photographic emulsion waste on both sides of the support,
For example, there is direct X-ray film, but most other photographic materials have a photographic emulsion layer on only one side of the support. Therefore, in the latter case, the photographic emulsion layer is
There is an unpacked surface, that is, a surface of the support, which is generally referred to in the industry as the ``pack'' of photographic light-sensitive materials. It is known that an antistatic layer is provided on the back surface of photographic light-sensitive materials in order to prevent uneven exposure due to static electricity that occurs during production or during use. For example, cationic polymers are described as antistatic agents in 48-11649-121523, 50-54672, 53-45231, and 53-92-125-1. It has been done. 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 contact R part of the photosensitive material,
In addition, contact with adhering substances such as dust and fibers often causes serious adverse effects. In particular, since the back side often comes into direct contact with various 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 overlapping the image surface during printing or video, and are a serious defect in practical use. In recent years, the use and processing methods for photosensitive materials have expanded, such as high-speed coating, rapid imaging, and rapid processing, and the diversification of environments in which photosensitive materials are used, such as in high-temperature and high-humidity environments, has changed the way photosensitive materials used to be treated. They are now subject to harsher handling, making it even more likely that scratches will occur and driveability will deteriorate. Therefore, there is a need for photosensitive materials that have surface qualities with high slipperiness and scratch resistance that can withstand even these 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 the slip agent, for example, polyorganosiloxane as disclosed in Japanese Patent Publication No. 53-292, U.S. Pat. No. 4,275,

There are problems in that scratches occur due to rubbing, and debris made of cationic polymers peels off. Therefore,
L. A possible method for solving this problem is to provide a surface layer containing a slipping agent as described below on the surface layer of the layer made of the cationic polymer. However, according to the study conducted by the present inventor, the antistatic properties of some of the lubricants described in E are significantly reduced, and the antistatic properties are significantly lowered.
In some cases, the antistatic effect cannot be obtained, and in some cases the antistatic properties are mixed, but if the material is rolled up and stored after the surface layer is provided during the manufacturing process of the photosensitive material. It was found that the slip agent contained in the surface debris migrates to the side of the support where the emulsion layer is provided, resulting in problems such as uneven coating of the emulsion. [Objective of the Invention J The object of the present invention is to maintain sufficient slipperiness and damage resistance even under high-speed conveyance conditions, without impairing the anti-static performance of a layer made of a cationic polymer, and to maintain sufficient slipperiness and damage resistance over time or under development. It is an object of the present invention to provide a photographic light-sensitive material having surface debris that is free from problems such as deterioration after processing and occurrence of uneven emulsion. [Summary of the Invention] The present invention provides at least one photosensitive silver halide emulsion layer on one side of a support, and a cationic polymer on the opposite side of the support from the emulsion layer side. In the silver halide photographic light-sensitive material No. 1 in which scraps consisting of

In particular, by using an ester compound containing a branched aliphatic hydrocarbon group, a surface layer with even higher slipperiness and scratch resistance can be obtained. Moreover, there is almost no deterioration in its slipperiness and scratch resistance even over time or after photo processing. Therefore, it can be particularly useful in the production of various photosensitive materials for rapid processing or the production of photosensitive materials for motion pictures. In addition, the photographic light-sensitive material is produced in good condition without causing problems such as clouding of the coating blood containing the ester compound during the production of the photographic light-sensitive material, or uneven coating during the formation of the emulsion layer due to the ester compound. It can be manufactured. Furthermore, there was no generation of white powder (crystal precipitation) due to bleeding on the obtained surface layer.
Therefore, it will not cause failure during use. Furthermore, it does not cause any adverse photographic effects (fogging, #? feeling, etc.) on the produced photographic light-sensitive materials. [Detailed Description of the Invention] The photographic material of the present invention comprises at least one layer of photosensitive silver halide emulsion waste on one side of the support, and a layer of photosensitive silver halide emulsion waste on the opposite side of the support from the emulsion layer. A layer made of a cationic polymer is attached to the surface, and a surface layer containing an aliphatic group-containing ester compound represented by the general formula [I], which is a characteristic requirement of the present invention, is attached on the layer made of the polymer. There is.
There are no particular limitations on the support on which the silver halide photographic emulsion layer described in L is provided.

Oil-soluble dyes can also be emulsified using the wood droplet dispersion method and added to the wood-philic colloid layer. The light-sensitive material of the present invention can be used as a multicolor photographic material having at least two different spectral sensitivities on the support. Multi-color natural color photographic materials usually have at least one red-sensitive emulsion layer, one radiation-sensitive milk I'iq layer, and one n-sensitive emulsion layer on a support. The arrangement of these pieces of waste can be chosen as desired. The preferred arrangement is from the support side to red sensitivity, M sensitivity and blue sensitivity in that order, blue sensitivity layer. The order is the green-sensitive layer and the red-sensitive layer, or the blue-sensitive layer, the red-sensitive layer, and the green-sensitive layer. Furthermore, any emulsion scrap having the same color sensitivity may be constructed of two or more emulsion layers having different sensitivities to improve the attained sensitivity, or a three-layer construction may be used to further improve graininess.
Furthermore, a non-photosensitive layer may be present between two or more emulsion layers having the same color sensitivity. It may also be configured such that emulsion layers of different color sensitivity are inserted between emulsion layers of the same color sensitivity. Sensitivity can also be improved by providing a reflective layer such as fine-grain silver halide under the high-sensitivity layer, especially under the high-sensitivity blue-sensitive layer. Generally, the red-sensitive emulsion layer contains a cyan-forming coupler, the green-sensitive emulsion layer contains a magenta-forming coupler, and the blue-sensitive emulsion waste contains a yellow-forming coupler, but different combinations may be used depending on the case. For example, it may be used in combination with an infrared-sensitive layer for pseudo-color photography or semiconductor laser exposure. The silver halide photographic emulsion layer is made of a coating solution (coating solution) in which the silver halide emulsion and wood-philic colloid are dissolved or separated.
Prepare a photosensitive liquid), apply the coating liquid on the above-mentioned support,
It can be formed by drying. Further, any wood-philic colloid layer can be added in a similar manner so as to have a 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 wood-philic colloid layers.
