Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide photographic material that is antistatic, and more particularly to a silver halide photographic material that is antistatic without adversely affecting photographic properties. .

[Background of the invention]

In recent years, the requirements for silver halide photographic materials (hereinafter referred to as photographic materials or simply referred to as light-sensitive materials) have become increasingly complex and diverse.In particular, the requirements for silver halide photographic materials (hereinafter referred to as photographic materials or simply referred to as light-sensitive materials) have become increasingly complex and diverse. Photosensitive materials are in demand.

In particular, in the case of X-ray photosensitive materials, in order to reduce the amount of X-rays the human body is exposed to, high sensitivity, high image quality, and quick information acquisition are required to obtain a large amount of information with a smaller amount of X-rays. Therefore, a photosensitive material suitable for rapid development processing is desired.

Since photosensitive materials generally consist of an electrically insulating support and photographic constituent layers, static electricity is generated during the manufacturing process or during use due to contact friction or peeling between the surfaces of the same or different materials. Charges tend to accumulate. The photosensitive emulsion layer is sensitized by the discharge of electrostatic charges accumulated before processing, resulting in dot-like spots or dendritic or feather-like line spots, so-called static marks, when photographic film is processed. . This significantly reduces the commercial value of the photographic film, and static marks appearing on, for example, medical or industrial X-ray films, can lead to very dangerous decisions. This phenomenon becomes apparent only after development, and is one of the most troublesome problems.

In addition, the accumulated electrostatic charge may cause secondary failures such as attracting dust to the surface of the film and making it impossible to apply the film uniformly. These static marks are becoming more likely to occur due to the increased sensitivity of photosensitive materials, high speed coating, high speed photography, high speed automatic processing, etc.

Methods have been considered to improve the conductivity of photosensitive material supports and various types of drum cloth surface layers, and attempts have been made to use various hygroscopic substances, water-soluble inorganic salts, certain surfactants, polymers, etc. Ta.

However, many of these substances exhibit specificity depending on the type of support and photographic composition, and often have an adverse effect on photographic performance.

In particular, antistatic methods for hydrophilic colloid layers are extremely difficult, as surface resistance may not be sufficiently reduced at low humidity, and adhesion failures often occur between photosensitive materials or other materials at high temperature and high humidity. be.

Furthermore, although they have an antistatic effect, such as polyethylene oxide compounds, there are many that have adverse effects on photographic properties, such as increased fog, desensitization, and deterioration of graininess.
- It has been difficult to find antistatic agents suitable for use in light-sensitive materials having emulsion layers on both sides of the support, such as Ray-sensitive materials.

In connection with the generation of static electricity due to contact friction or peeling mentioned above,
It is also important to improve the sliding properties of the surface of the photosensitive material.

In other words, contact with various rollers, equipment, and photosensitive materials during manufacturing processes such as coating, drying, and processing and packaging of photosensitive materials, as well as during film loading, photographing, automatic processor processing, and 4-photography. There are many opportunities for friction.

Therefore, in order to improve the sliding properties of photosensitive materials, there is a need to reduce the sliding friction of photosensitive materials in order to prevent surface abrasions and scratches caused by friction, as well as to improve film feeding properties, as well as antistatic properties. Ru.

Typical improvement methods that have been proposed in the past include those using organosiloxanes, such as U.S. Pat. etc. are disclosed.

Although each of these known improvement means improves the slipperiness to some extent, it is not always sufficient (η), and other properties such as anti-static properties deteriorate, so they are not always satisfactory.

On the other hand, during the production of photographic light-sensitive materials formed from many hydrophilic organic colloid layers, it is required that these coating solutions be coated in a thin layer uniformly and at high speed without causing repelling or uneven coating. In producing light-sensitive materials, a support is often coated with multiple layers of coating solutions containing photographic emulsions and other hydrophilic organic colloids such as gelatin.

Obtaining the required coating characteristics when coating gelatin or other organic colloid liquids on such organic colloid layers, such as gelatin, is more difficult than when coating gelatin colloid liquids directly on the support. accompanied by. Especially when the lower layer is in a cooled and set state immediately after being applied, it is early in the summer.

Conventionally, various surfactants (hereinafter referred to as activators) have been used as coating aids for various coating solutions for photosensitive materials, as emulsifiers, or as additives for improving the surface properties of photographic surface layers. . In particular, saponin has been widely used as a coating aid in the photographic industry, but it has drawbacks such as easy foaming, large fluctuations in quality because it is a natural product, and poor properties as a coating aid. In addition, the effects of various other synthetic activators on the coating characteristics and surface characteristics of various photographic coating solutions or photographic coating layers exhibit specificity depending on the type of activator, and therefore their range of use is limited. Many different types of active agents are selected and utilized depending on the particular application.

However, many of these were unsatisfactory, with photographic properties, especially deterioration of film properties at high temperatures and high humidity, stability of the compound itself, or high-speed coating properties being insufficient.

[Purpose of the invention]

Therefore, the present invention has been made in view of the above circumstances, and a first object of the present invention is to provide an antistatic silver halide photographic light-sensitive material that can be coated at high speed without bubbles, repelling, or other coating failures. It's about doing.

A second object of the present invention is to provide a silver halide photographic material with improved surface slipperiness.
