Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a silver halide black-and-white photographic light-sensitive material, and more specifically, a silver halide excellent in adhesiveness between a coating film including a light-sensitive layer and a support. The present invention relates to a method for producing a black-and-white photographic light-sensitive material.

[0002]

2. Description of the Related Art Many studies have been made in the past regarding the use of high-boiling organic solvents and latex polymers in photographic light-sensitive materials. It is described that the adhesive strength can be improved by using a certain amount of latex polymer.

[0003]

Generally, a silver halide photographic light-sensitive material has a light-sensitive silver halide emulsion layer and a protective layer on a support. Add a matting agent to this protective layer,
It is known to prevent blocking at high temperature and high humidity and to improve film transportability. However, since a film which is stored in a so-called long roll in a cartridge is developed after the development process, it is necessary to sufficiently exhibit the above effect even after the process. For this reason, it has become necessary to incorporate a large amount of matting agents of a type that will not dissolve even in development processing (hereinafter referred to as insoluble matting agents).

Further, in recent years, in order to reduce the cost, in the development laboratory, the development processing speed has been increased to shorten the development processing time. In such a situation, when a sensitive material having a matting agent of a type that does not dissolve in the developing process on the polyester support is conveyed by a high-speed developing machine, two sheets are installed between the tanks of the developing machine. There has been a problem that the matting agent is peeled off (peeling off) when passing through a liquid draining device (called a rubber lip) composed of a rubber plate. In particular, it has been found that many conventional matting agents have a broad particle size distribution, and those having a large particle size selectively cause peeling failure. Further, it is considered that one of the causes is that the polyester support has a lower water absorption than the conventional cellulose triacetate, and the rigidity of the support during development processing is relatively high. Further, it has been demanded to enhance the compatibility between the matting agent and gelatin as a binder. Therefore, an object of the present invention is to provide a silver halide black-and-white photographic light-sensitive material having excellent adhesive strength between a support and each coated layer.

In a black-and-white photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer and an antihalation layer between the emulsion layer and a support, the content of a high-boiling organic solvent and the content of a latex polymer relative to the content of gelatin. The total dry film thickness of the layers having a weight ratio of 0.1 to 3.0 is 5% of the total dry film thickness of all the layers on the side of the photosensitive layer coated on the support. It is achieved by a silver halide black-and-white photographic light-sensitive material characterized by being 50% or more and less than 50%.

Further, the support is composed of a poly (alkylene aromatic dicarboxylate) compound and has a glass transition temperature of 50 ° C. to 200 ° C., and the support is subjected to glow discharge treatment or ultraviolet irradiation. Alternatively, it is also preferable to apply a conductive layer of the photographic light-sensitive material after the corona discharge treatment or before the heat treatment of the support at a temperature of 50 ° C. or higher and Tg or lower of the support.

The thickness of these supports is 50 μm or more and 30
It is 0 μm or less. The thickness is more preferably 50 to 200 μm, further preferably 80 to 115 μm, and particularly preferably 85 to 105 μm. However, when used as a sheet-shaped photosensitive material, the thickness may exceed 100 μm. The polyester support is preferably heat-treated at 50 ° C or higher and lower than Tg, more preferably Tg-20 ° C or higher and lower than Tg. The heat treatment may be performed at a constant temperature within this temperature range, or may be performed while cooling. The average cooling rate of cooling is −0.01 to −20 ° C./hour, more preferably −0.1 to −5 ° C./hour. This heat treatment time is 0.1 hours or more and 1500 hours or less, and more preferably 0.5 hours or more and 200 hours or less.

In order to further increase the effect of eliminating the curl, a heat treatment is performed at a temperature higher than Tg and lower than the melting point (melting temperature determined by DSC) before the heat treatment to erase the heat history of the support. The heat treatment may be performed at a temperature of 50 ° C. or higher and lower than Tg. In the present invention, this heat treatment is referred to as "preheat treatment".
The heat treatment at 40 ° C. or higher and lower than Tg described in the preceding paragraph is called a “post heat treatment” to distinguish them. The pre-heat treatment temperature is Tg or higher and lower than the melting point, and more preferably Tg + 20 ° C. or higher and crystallization temperature (crystallization temperature determined by DSC) or lower.
When the pre-heat treatment is performed at a temperature equal to or higher than the melting point, the elasticity of the support is remarkably reduced, which causes problems in surface condition and transportability.
The pre-heat treatment may be carried out within this temperature range at a constant temperature (constant temperature pre-heat treatment), may be carried out while lowering the temperature (pre-heat treatment before cooling), or may be carried out while raising the temperature (rise of temperature). Pre-heat treatment). Pre-heat treatment time is 0.1 minutes or more 1500
The time is less than or equal to the hour, more preferably 1 minute or more and less than 1 hour. After this pre-heat treatment, a post-heat treatment is carried out, but it may be rapidly cooled from the pre-heat treatment end temperature to the post-heat treatment start temperature, or may be gradually cooled to the post-heat treatment start temperature across Tg. Alternatively, the temperature may be once cooled to room temperature and then raised to the post-heat treatment temperature. Although there are several combinations of these pre-heat treatment and post-heat treatment methods, Tg-Tg-
It is preferable to perform the post-heat treatment while cooling to a temperature range of 20 ° C at a cooling rate of -0.1 to -5 ° C / hour.

The heat treatment of such a support may be carried out in the form of a roll or may be carried out while being conveyed in the form of a web. In the heat treatment in the roll form, the surface shrinkage such as wrinkles due to winding tightness and the cutout of the core portion is likely to occur due to the heat shrinkage stress generated during the heat treatment. For this reason, unevenness is imparted to the surface (for example, conductive inorganic fine particles such as SnO ₂ and Sb ₂ O ₅ are applied) to reduce creaking between the supports, thereby preventing wrinkles due to winding tightening, and It is desirable to make a contrivance such that a knurl is provided on the end of the core and the end of the core is slightly raised to prevent the cut end of the winding core from appearing. On the other hand, when the heat treatment is carried out in the form of a web, a long post-heat treatment step is required, but a better surface condition of the support can be obtained as compared with the heat treatment in the form of a roll. Among these heat treatment methods,
It is preferable that the pre-heat treatment is performed in a web shape and the post-heat treatment is performed in a roll shape. This is because if the pre-heat treatment is carried out in the form of a web, planar defects are less likely to occur as compared with the case of performing it in the form of a roll, and the post-heat treatment requires a relatively long time.

These heat treatments are carried out after the support film formation, the glow discharge treatment, the back layer application (antistatic agent, slip agent, etc.),
It may be carried out at any stage after application of the undercoat. Preferably after application of the antistatic agent. As a result, it is possible to prevent the attachment of dust due to electrification, which causes a surface failure of the support during heat treatment. Furthermore, in the method for heat-treating the polyester of the present invention, in order to shorten the time, it is preferable to preliminarily heat to Tg or more for a short time (preferably, perform Tg treatment at 20 ° C. or higher and 100 ° C. or lower for 5 minutes to 3 hours). . Further, the roll core used in the heat treatment is preferably one having a built-in electric heater or a structure capable of flowing a high-temperature liquid so that it can be hollow or heated for efficient temperature propagation to the film. The material of the roll winding core is not particularly limited, but it is preferable that the material does not undergo strength reduction or deformation due to heat, and examples thereof include stainless steel, aluminum, and resin containing glass fiber. Further, rubber or resin may be lined on these winding cores, if necessary.

Further, an ultraviolet absorber may be kneaded into these polymer films for the purpose of imparting stability with time. It is desirable that the ultraviolet absorber has no absorption in the visible region, and the amount of the ultraviolet absorber is usually about 0.5% to 20% by weight, preferably about 1% to 10% by weight based on the weight of the polymer film. It is. If the amount is less than 0.5% by weight, the effect of suppressing deterioration of ultraviolet rays cannot be expected.
As the ultraviolet absorber, 2,4-dihydroxybenzophenone, 2-hydroxy-4-methoxybenzophenone,
2-hydroxy-4-n-octoxybenzophenone,
4-dodecyloxy-2-hydroxybenzophenone,
Benzophenone-based compounds such as 2,2 ', 4,4'-tetrahydroxybenzophenone and 2,2'-dihydroxy-4,4'-dimethoxybenzophenone, 2 (2'-hydroxy-5-methylphenyl) benzotriazole, 2
(2'-hydroxy 3 ', 5'-di-t-butylphenyl) benzotriazole, 2 (2'-hydroxy-3'
-Di-t-butyl-5'-methylphenyl) benzotriazole and the like; and salicylic acid-based ultraviolet absorbents such as phenyl salicylate and methyl salicylate.

Polyester, particularly aromatic polyester, has a high refractive index of 1.6 to 1.7, whereas gelatin, which is the main component of the photosensitive layer coated on the polyester, has a refractive index of 1.
Since this value is 50 to 1.55, which is smaller than this value, when light is incident from the film edge, it is reflected at the interface between the support and the emulsion layer to cause a so-called light piping phenomenon (edge covering).
In order to avoid such a light piping phenomenon, a method of including inert inorganic particles in a film and a method of adding a dye are known. The method of adding a dye is preferable because it does not significantly increase the film haze. Regarding the dye used for the film dyeing, the color tone is preferably gray dyeing due to the general properties of the photosensitive material, and is preferably excellent in heat resistance in the film forming temperature range of the polyester film, and excellent in compatibility with the polyester. . From the above viewpoints, as the dye, it is possible to achieve the object by mixing commercially available dyes for polyester such as Diaresin manufactured by Mitsubishi Kasei and Kayaset manufactured by Nippon Kayaku.

The polyester film according to the present invention can be imparted with slipperiness depending on the intended use, and kneading with an inert inorganic compound or coating with a surfactant is generally used. Such inert inorganic particles include SiO ₂ , TiO ₂ , BaSO ₄ , CaCO ₃ ,
Examples include talc and kaolin. In addition to the lubricity imparted by the external particle system in which inert particles are added to the polyester synthesis reaction system described above, a lubricity imparting method using an internal particle system in which a catalyst or the like to be added during the polymerization reaction of the polyester is precipitated can also be adopted. It is. As the external particle system, it is desirable to select SiO ₂ having a refractive index relatively close to that of the polyester film, or an internal particle system capable of relatively reducing the precipitated particle size.

In order to firmly adhere the photographic layers (the photosensitive silver halide emulsion layer, the intermediate layer, the filter layer, the protective layer, the conductive layer and the back layer) to the support of the present invention, a surface activation treatment is carried out. After that, the photographic layer may be directly applied to obtain an adhesive force, or after these surface treatments may be carried out once or without a surface treatment, an undercoat layer may be provided and a photographic layer may be provided thereon. The surface treatment is preferably a method of providing a photographic layer on the undercoat layer after the glow discharge treatment.
