Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a silver halide photographic material having at least one light-sensitive silver halide emulsion layer on one side of a support. More specifically, the present invention relates to a silver halide photographic material having a surface layer with improved physical properties such as slipperiness and scratch resistance (hereinafter simply referred to as a photographic material or a light-sensitive material).

[Prior Art] Photographic light-sensitive materials generally have a subbing layer, either directly or on one or both sides of a support, such as cellulose triacetate, polyethylene terephthalate, paper, or paper coated with polyethylene terephthalate on both sides of the paper. A silver halide photographic emulsion layer and, if necessary, an interlayer, a protective layer, a filter layer, an antistatic layer, an antihalation layer, etc. are coated in various combinations via a silver halide emulsion layer. These layers generally consist of a hydrophilic binder such as gelatin. An example of a photographic light-sensitive material that has photographic emulsion layers on both sides of the support is direct X-ray film, but most other photographic materials have a photographic emulsion layer formed on only one side of the support. ing. 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 '
4 R-back surface of photosensitive materials.

, photographic materials are handled by 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 image transfer. Contact friction between adhesive parts of photosensitive materials or deposits such as dust and fibers often causes serious adverse effects. In particular, since the back surface often comes into direct contact with various types of equipment, it is prone to scratches and gouges, deterioration of the drivability of photosensitive materials in cameras and other machine troughs, and generation of film waste.

These scratches appear overlapping the image surface during printing or imaging, and are a serious defect in practical use. Furthermore, 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 they are used, such as in high-temperature and high-humidity environments, has made photosensitive materials less conventional. They are now subject to even harsher handling, making it more likely that scratches and deterioration of drive performance will 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 Publication No. 2, higher fatty acid amide as disclosed in U.S. Pat. No. 4,275,146, Japanese Patent Publication No. 58-3354
Publication No. 1, British Patent No. 927,446 or JP-A-55-126238 and JP-A-58-90633
Higher fatty acid esters (esters of fatty acids having 10 to 24 carbon atoms and alcohols having 10 to 24 carbon atoms) as disclosed in US Pat. No. 3,933,516
Higher fatty acid metal salts such as those disclosed in the patent specification are known.

It is known that an antistatic layer is provided on the back surface of the above 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-49-121523, JP-A-50-546
No. 72, No. 53-45231, or No. 53-92
No. 125 and other publications describe cationic polymers as useful antistatic agents. Even in photographic materials having the above-mentioned cationic polymer layer on the back surface of the support, there are problems such as scratches caused by contact friction and peeling of the cationic polymer layer as described in 11. A surface layer containing the above-mentioned slip agent is provided on the layer made of the cationic polymer.

[Problem M that the present invention seeks to solve] However,
It is true that the slipperiness and scratch resistance of photographic materials can be improved by using these known methods, but they are not satisfactory under harsh conditions such as in recent high-speed conveyance processes. It is often accompanied by disorders such as:

For example, when silicone is used as a slip agent for the back layer (a layer formed on the back surface), the added silicone migrates to the surface of the support on which the photographic emulsion is coated, causing , repellency, poor wetting, and other coating properties may be significantly impaired, resulting in uneven coating of the emulsion. In addition, higher fatty acids, polyhydric alcohol esters of higher fatty acids, higher fatty acid amides, and higher alcohol esters of the above-mentioned higher fatty acids (from 10 carbon atoms to
When esters of C.24 fatty acids and alcohols having 10 to 24 carbon atoms), higher fatty acid amides, and higher alcohol esters are used as slipping agents for the back layer, they exhibit fairly good slipping properties and scratch resistance at the beginning of production. However, the surface of the back layer may become white due to bleeding of the lubricant, or the lubricant may be eluted or diffused during the development process, resulting in loss of its effectiveness and contamination of the processing solution. be.

In addition, to provide a back layer using a slip agent, it is usually dissolved or dispersed in a suitable solvent alone or together with a binder to prepare a coating solution (A), and this is applied onto the support. A coating method is used, but in this case, if the solvent is one that swells the support, the slip agent will diffuse into the interior and will not remain on the surface, making it difficult to obtain good slip properties. there were. For this reason, the solid content of the lubricant is increased, but this increases the concentration of the lubricant in the coating solution, making it easier for the lubricant to precipitate, causing contamination during the development process, and even slight uneven drying. There were cases in which uneven coating of the slip agent occurred, impairing the appearance of the photosensitive material. Furthermore, when a surface layer containing a slip agent is provided on top of a layer made of a cationic polymer, the antistatic property decreases and the sufficient antistatic effect is reduced to 1! - It was also found that there are cases where it is not possible.

[Objective of the Invention] The first object of the present invention is to maintain sufficient slipperiness and scratch resistance even under high-speed conveyance conditions, and to avoid problems such as deterioration over time or after development processing and uneven coating of emulsion. It is an object of the present invention to provide a photographic material having a surface layer that does not cause any damage.

Furthermore, it is an object of the present invention that the surface layer has the above-mentioned excellent physical properties.
Another object of the present invention is to provide a photographic material having a surface layer that does not impair the antistatic properties of the layer made of a cationic polymer.

[Summary of the Invention] The present invention provides a silver halide photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer on one side of a support, in which at least one surface layer provided on the light-sensitive material has the following general composition.

Furthermore, there is almost no deterioration in the slipperiness and scratch resistance even over time or after photographic processing. Therefore, it can be used particularly advantageously in the production of quick-processing photosensitive materials or positive photosensitive materials for movies. Note that the above slip properties and scratch resistance are even better than when an ester compound containing a branched aliphatic hydrocarbon group is used as a slip agent.

Further, during the production of photographic light-sensitive materials, emulsion coating unevenness caused by migration of the ester compound does not occur, and an emulsion layer can be formed in good condition.

Furthermore, by using the ester compound according to the present invention, the antistatic function of the cationic polymer layer is not impaired, and furthermore, the produced photographic light-sensitive materials are not adversely affected photographically (occurrence of fog, increase in (feelings, etc.) will not occur.

1-chloro-1-pyridinomethylene)pyrrolidinium
(2-naphthalenesulfonate, etc.) also have a fast curing speed and are excellent.

The emulsion layer and auxiliary layer (wood-philic colloid layer) of photosensitive materials contain various coating aids, antistatic properties, smoothness improvement, emulsification dispersion, adhesion prevention, and photographic property improvement (e.g. development acceleration, high contrast, sensitization), etc. For this purpose, one or more surfactants may be included.

A preferred layer arrangement is, from the support side, in the order of red sensitivity, green sensitivity and blue sensitivity, blue sensitivity it, green sensitivity and red sensitivity, and )B, or blue sensitivity, red sensitivity and green sensitivity in this order. Also, any given emulsion layer with the same color sensitivity can be mixed with two emulsion layers with different sensitivities.
It may be composed of emulsion layers from layer to F to improve the sensitivity, or it may be composed of three layers 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 green-sensitive emulsion layer contains a magenta-forming coupler, and the blue-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 5 quality or semiconductor laser exposure.

The silver halide photographic emulsion layer consists of a coating liquid (
preparing a photosensitive liquid) and coating the coating liquid on the above-mentioned support;
It can be formed by drying. Further, an optional auxiliary layer (hydrophilic colloid layer) can also be provided 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 auxiliary layers. If necessary, multilayer coating can be applied by coating methods described in U.S. Pat. No. 2,681,294, U.S. Pat. may be applied at the same time.

Next, a method of using the photographic material of the present invention will be explained.

The photographic material of the present invention is used after being subjected to exposure, development, and fixing treatments. Below, they will be explained in order.

Various exposure means can be used for the photosensitive 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 or writing light source. Natural light (sunlight), incandescent lamps, halogen-filled lamps, mercury vapor lamps, fluorescent lamps, and flash light sources such as strobes or metal-burning flashbulbs are common.

Gaseous, dye solution or semiconductor lasers, light emitting diodes and plasma light sources emitting in the wavelength range from ultraviolet to infrared acids can also be used as recording light sources. In addition, linear or planar microshutter arrays using phosphor screens (CRT, etc.), liquid crystals (LCD), and lanthanum-doped lead titanium zirconate (PLZT) emitted from phosphors excited by electron beams, etc. It is also possible to use an exposure means combining two light sources. If necessary, the spectral distribution used for exposure can be adjusted using color filters.
