SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE:To stably disperse and incorporate a hydroquinone deriv. having a sulfonyl group into the above photosensitive material so that the purpose of using this deriv. is sufficiently achieved by incorporating a dispersion contg. the hydroquinone deriv. into the material. CONSTITUTION:The hydroquinone deriv. contg. the sulfonyl group is incorporated into the hydrophilic colloidal layer of the silver halide photographic sensitive material having the hydrophilic colloidal layer on a base. The dispersion formed by dispersing the hydroquinone deriv. having the sulfonyl group into an aq. phase by an amphoteric surfactant is incorporated into the above- mentioned layer. The hydroquinone deriv. dispersion having the sulfonyl group is dispersed and incorporated into the photosensitive material in such a manner that the dispersion is stably maintained in a long-term preservation and the purpose of using this dispersion is sufficiently achieved.
