(Prior art) Normally, when a silver halide photographic light-sensitive material is exposed to light including light in the photosensitive region of the light-sensitive material and developed, the blackening density increases as the exposure amount increases, and at a certain exposure amount. However, when the exposure amount is further increased, the blackening density decreases.

Therefore, if a silver halide photographic emulsion is optically or chemically given an appropriate amount of fog so that the blackening density reaches its maximum value, solarization will occur upon exposure and a positive image can be directly obtained. . As is well known, a light-sensitive material that utilizes such a reversal phenomenon is called a direct reversal silver halide photographic light-sensitive material.

This type of direct reversal silver halide photographic light-sensitive material is used for copying various types of photographs, but when used for copying photographs with relatively continuous gradation such as X-ray photographs, it is important to obtain good reproduction. In order to achieve this, a soft direct reversal photographic light-sensitive material is desired, and in particular, there is a demand for the development of a light-sensitive material whose contrast can be effectively reduced while maintaining a predetermined maximum density.

As one of this kind of technical means, for example, US Pat.
, 615,573, it has been proposed to reduce the contrast by mixing monodisperse direct reversal silver halide photographic emulsions with different degrees of fog. 11 silver photographic emulsions! The manufacturing process is relatively complex, and it is difficult to manufacture it stably and reproducibly. In addition, as a simple method in terms of manufacturing process, for example, as described in U.S. Pat. No. 3,364,026, a certain type of merocyanine dye of the sensitizing dye type is directly added to the reversal silver halide emulsion, thereby reducing the contrast. is proposed. However, when such a sensitizing dye is added to a direct reversal silver halide emulsion, fog nuclei are generally easily oxidized during storage of the direct reversal silver halide light-sensitive material, resulting in a decrease in maximum density and a change in gamma over time. After photographic processing of direct reversal silver halide light-sensitive materials, dyes remain in the silver halide emulsion, which often causes undesirable phenomena in terms of photographic image quality, such as color staining.

It is produced by mixing and adding aqueous solutions of water-soluble halogen salts, such as potassium bromide and potassium iodide, into gelatin or other hydrophilic organic colloids, or into hydrophilic organic colloid solutions that also contain halogen salts. At this time, it is produced in the presence of ammonia. This ammonia may be added to the silver salt solution or to the halide salt solution, or may be previously contained in the hydrophilic colloidal solution, or may be added as a separate solution. . Further, as for the mixing method, the silver salt solution and the halogen solution may be mixed at the same time, or they may be added separately, or each may be divided and mixed sequentially. This mixing and physical ripening is generally carried out at a temperature of 20° to 70°C, preferably within the range of 30 to 60°C. In addition, in terms of silver halide composition, silver iodide contains 2 to 8 moles of silver iodide, and if the silver iodide content is less than 2 moles, sufficient reduction in contrast cannot be obtained, and if the silver iodide content is less than 2 moles, processing is difficult. A problem arises.

An aqueous copolymer dispersion obtained by diluting a copolymer consisting of three types of heptadons of 10 wt% methyl acrylate and 40 wt% butyl methacrylate to a concentration of 10 wt% was used as a subbing liquid. A sample was prepared by distributing 4 g of silver per square meter onto the coated polyester film base and drying. Each sample I obtained in this way was exposed to light using a sensitometric light wedge, and then processed with XD-90 developer and XF fixer at 90% A second development process was performed, and the maximum and minimum density gammas of each sample were determined. The results are shown in Table-1.
