SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE:To attain high sensitivity and stability by specifying silver halide particles contained in an emulsion layer. CONSTITUTION:Silver halide particles contained in an emulsion layer are principally silver chlorobromide particles contg. >=90mol.% silver chloride. Each of the particles has at least one silver bromide-rich region near the vertex and the average silver bromide content of the surface is <=15mol.%. The pref. amt. of the silver chlorobromide particles is >=70mol.% of the amt. of all the silver halide particles in the emulsion layer. High sensitivity is attained, the stability is remarkably improved, fogging is inhibited without deteriorating the rapid developability and superior stability is obtd.
