CONSTITUTION:At least one conductive layer contg. fine conductive particles consisting mainly of at least one metal oxide selected from oxides of Zn, Ti, Sn, In, Si, Mo, and W, or at least one composite metal oxide composed of them is formed in a photogaphic material having a silver shalide emulsion layer on a support.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a silver chloride photosensitive material with improved antistatic properties, and in particular, a photographic photosensitive material with improved antistatic properties without affecting the photographic properties. It's about materials.

Photographic light-sensitive materials generally consist of an electrically insulating support and a photographic layer, so during the construction of the photographic light-sensitive material and during use, there is a risk of contact with the surface of the material. Electrostatic charges often accumulate due to friction or abrasion. This accumulated electrostatic charge causes many problems, but the most important problem is that the electrostatic charge accumulated before image processing is discharged and the photosensitive emulsion layer is exposed to light, causing the photographic film to become exposed. When treated, it produces dot-like spots or dendritic or feather-like lines. These are called static marks (1444), which significantly reduce the commercial value of the photographic film, and in some cases completely destroy it. For example, if it appears in medical or industrial X-ray films, it is easy to see that it will lead to very dangerous judgments. This phenomenon becomes clear only when the object is visualized as a block, and it is one of the most troublesome problems. In addition, these accumulated electrostatic charges may cause problems such as dust adhesion to the film surface or uneven coating.
It can also cause further failures.

As mentioned above, such electrostatic charges are often accumulated during the production and use of photographic materials. This occurs due to separation of the support surface and emulsion surface during the unwinding process. In the finished T7 product, depending on the difference between the base surface and the emulsion surface when the photographic film is wound and switched, the front part is the mechanical part in the X-Rayfil AO AutowJ camera or the fluorescent sensitizer. This occurs due to contact separation of the threshold with the paper, etc.

4 occurs due to contact with other comprehensive value materials. Stagnation of photographic materials induced by such electrostatic charge accumulation;
Marks become more noticeable as the sensitivity of photographic materials increases and the processing speed increases. In recent years, the occurrence of physical static marks has become more common due to the increased sensitivity of photographic materials and the increased exposure to harsh sea conditions such as high-speed coating, high-speed photography, and high-speed auto-cyclization. 〈It has become.

The best way to eliminate these electrostatic disturbances is to ensure that the electrical conductivity of the material allows the electrostatic charge to dissipate in a short period of time before the accumulated charge is discharged.

Therefore, methods have been considered to improve the conductivity of the support of photographic light-sensitive materials and the surface layer coated with various materials, including the use of various hygroscopic substances, water-soluble surfactants, surfactants, polymers, etc. A friend has been tried.

j! Surfactants such as those described in U.S. Pat.
Colloidal silica groups, such as those described in Co., Ltd., No. 1,42/, are known.

However, many of these materials exhibit specificity due to differences in film supports and photographic compositions, giving better results for certain film supports and photographic emulsions and other photographic compositions. But other O14
The film sleeves and photographic components that have been removed are not only completely useless in preventing static electricity, but may also have no negative effect on photographic properties. Furthermore, many of these materials have a major drawback in that their conductivity is dependent on the placement, and they lose their ability to function as a conductive layer under low humidity.

Also, Tokuko Akira J! No. r-44/4 describes the technology of using stannic oxide as an antistatic treatment agent.
This technology uses an amorphous stannic oxide colloid whose electrical conductivity is fi11! It is a material that has dependence and loses its function as a conductive layer under low humidity, and is essentially no different from the various substances described above.

On the other hand, for example, U.S. Patent No. J,04,700, Ko//JJJ4E issue and the same! 1-/JfJ No. 7, etc., crystalline zinc oxide, crystalline zinc oxide, whose conductivity does not depend at all on the 61 area, as a conductive material for a conductive support of an electrophotographic photoreceptor or an electrostatic inorganic material. It is known to use metal oxides such as stannic and indium oxide.

However, it is completely unknown that these crystalline metal oxide particles can be used as antistatic agents in silver halide emulsions, and furthermore, it is unclear how these conductive materials interact with the silver halide photosensitive emulsion layer. It was completely unexpected whether it would last or not. By the way, please refer to the US patent.
Silver halide and silver halide are used as the conductive material described in No. 133, but these conductive materials are IFFgJ, -21,44! As shown in No. 2, it is clearly shown that there is an interaction with the silver halide emulsion layer, which may have an adverse effect on photographic properties.

Furthermore, the l1ii me obtained using the photographic light-sensitive material is
There are cases of observation using transmitted light and cases of observation using reflected light. In the latter case, it is preferable that the reflectance of the part without the minus sign is as high as possible. In the former case, it is preferable to increase the intensity of the light in the area where there is no light, and it is desirable to reduce light scattering by the photographic light-sensitive material. For the purpose of reducing light scattering as much as possible, there are major restrictions when introducing a conductive layer into a photographic light-sensitive material to prevent static electricity. The above-mentioned conductive polymer or surfactant, which has the drawback of losing its function as a conductive layer once applied, must be used in a way that it is compatible with the binder or forms a fine micelle state. I didn't get it. Accordingly, the aforementioned U.S. Pat.
