DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for developing a silver halide photographic light-sensitive material, and particularly to a method for performing ultra-rapid processing using a roller transport type automatic developing machine (hereinafter referred to as a roller developing machine). The present invention relates to a photographic light-sensitive material having a small number of white missing pinholes and a developing method thereof.

[0002]

2. Description of the Related Art In recent years, high-speed rapid processing has rapidly become widespread in the development process of silver halide photographic light-sensitive materials (hereinafter referred to as "sensitive material"). Has been shortened to. A light-sensitive material that gives a sufficient blackening concentration in a short time, and a property that fixing, washing, and drying are completed in a short time are required. In particular, various methods for rapidly completing drying have been studied so far, but methods commonly used to improve the drying properties of the light-sensitive material include reducing the amount of gelatin applied and hardening the coated gelatin film. There is a method of reducing the water content in the light-sensitive material before the start of drying by strengthening the film. The drying time can be shortened by reducing the gelatin coating amount, but the occurrence of white holes in the film after the processing by the roller transport type automatic developing machine increases. In particular, the white hole pinhole at the highest density portion becomes very noticeable. In particular, there is a risk of misdiagnosis of calcification when reading mammography images.

These emulsions have an average particle size of about 0.2 (measured by, for example, a projected area method or a number average method).
And 0.6 μm of emulsion grains are preferred. An average particle size of 0.25 to 0.5μ is more preferable. The emulsion may be a mixture of coarse particles and fine particles. The particle shape is cubic, octahedral, tetrahedral, potato-like, spherical, plate-like, and plate-like with a particle size of 5 times or more the particle thickness (for details, see RESEARCHDISCLOSURE) Item No. 2253
4p. 20 to p. 58 (described in January, 1983)). Substantially non-light-sensitive emulsions (for example, fine-grained emulsions with internal fogging) may be mixed with these light-sensitive emulsions. Of course, they may be separately applied to different layers.

Further, even if the crystal structure of the silver halide grains is uniform up to the inside, the silver halide grains may have a layered structure in which the inside and the outside are different from each other, as well as British Patent 635,841 and US Pat. A so-called conversion type as described in Japanese Patent No. 622,318 may be used.
