Developing agent for silver halide photographic material, developing solution composition and method for developing silver halide photographic material |
摘要 |
A silver halide photographic material is processed with a developing solution containing at least one kind of developing agent represented by the following general formula (A): <IMAGE> (A) wherein R1 and R2 may be the same or different, and each represents a hydrogen atom or a substituent group, with the proviso that R1 and R2 are not methyl groups at the same time nor a combination of a hydrogen atom and a methyl group, thereby providing a novel method for forming an image by use of the developing solution not using a dihydroxybenzene compound as the developing agent, and more particularly a superhigh contrast negative image by use of the photographic material containing a hydrazine compound.
