Abstract
A processing chemical for light-sensitive silver halide photographic material, comprising a cyclodextrin compound, which can contribute a decrease in packaging materials, transportation cost and storage space, can be free from lateral cracking at the formation of tablets, and can bring about an improvement in storage stability after being formed into processing solutions (i.e., more free from occurrence of stain during developing and scratches in light-sensitive materials having been processed, caused by deposition of crystals).
