Title:
SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JPS63264740
Kind Code:
A
Abstract:

PURPOSE: To obtain the titled material contg. an inner latent image type silver halide emulsion having the excellent sensitivity, graininess, reciprocity law characteristics and preservation by incorporating an emulsion which is chemically sensitized so as to have a specified condition in the latent image distribution of a silver halide photographic emulsion, in the titled material.

CONSTITUTION: The silver halide emulsion contd. in at least one layer of the emulsion layers has at least one of the maximal value within the particle of the emulsion in the latent image distribution of said emulsion. The emulsion layer is chemically sensitized in such the way that the position (mode) of existing the maximal value lies in a depth of <0.01μm from the surface of the particle, and the numbers of the latent image in the surface of the particle are a range of more than one-fifth and less than one time of said max. maximal value. Thus, the titled material contg. The inner latent image type silver halide emulsion which is capable of giving the good sensitivity and graininess, and has the excellent reciprocity law characteristics and preservation, is obtd.
