LIGHT-SENSITIVE SILVER HALIDE PHOTOGRAPHIC MATERIAL

摘要

A new polymer compound having the guanidyketimine structural unit of the formula WHEREIN X is an acid radical and n is 1 or 2 has been synthesized. The said compound is useful as a mordant in a light-sensitive silver halide photographic material in order to prevent undesired migration of an acidic dye contained in a certain layer of the said photographic material. This greatly enhances sharpness to the image obtained from the said photographic material.
