Photographic processing agents and a method for processing light-sensitive photographic
materials |
(57) A photographic processing agent and a processing method for photographic material
using the processing agent are disclosed. The processing agent is an inclusion compound
comprised of a host enclosing an effective component for processing of a photographic
material as its guest and used in a processing solution for pfocessing the photographic
material. Various kinds of effective components for photographic processing can be
used in the form of the inclusion compound of the invention. The photographic processing
solution containing the effective component in the form of inclusion compound is improved
in its stability in the course of running the processing. As a result of that, good
properties of the photographic material can be stably obtained by using the processing
solution.
