Direct-positive photographic materials containing a nucleator in solid particle dispersion form.

摘要

A direct-positive image-forming photographic material comprises a supporting substrate bearing a light sensitive, nonprefogged silver halide photographic emulsion capable of forming an internal latent image and includes a water-insoluble nucleator. The nucleator is incorporated in the photographic material in the form of a solid particle dispersion to improve the storage stability of the photographic material. The development rate of the photographic material may be increased by use of a developer containing an activator for the nucleator.
