Granular solid photographic processing agent and production method thereof

Abstract

In order to provide a granular solid processing agent capable of avoiding consolidation among its constituent granules even when the granules sustain some damage by vibrations during transportation or/and are placed under high humidity conditions, and thereby maintaining qualities in the solid processing agent, and a method of producing such a granular solid processing agent, disclosed are solid processing agents for silver halide photosensitive materials, which each have granules containing an organic acid whose ammonium salt has a critical relative humidity of at least 70% RH, particularly the solid processing agents for silver halide photosensitive materials whose granules are core-shell granules containing the organic acids in their individual shell layers.
