Abstract

PURPOSE:To stabilize sensitivity specks in an emulsion and a latent image and to attain satisfactory developability and high sensitivity by using silver halide particles each having a specified silver halide coat and by adding a heterocyclic compd. contg. nitrogen to the emulsion. CONSTITUTION:Silver halide particles each consisting of a silver halide matrix and a silver halide coat having >=30mol.% Cl<-> content on the matrix are used in an emulsion and a heterocyclic compd. contg. nitrogen is added to the emulsion. The halogen compsn. of the coat is AgCl or AgClBr, preferably AgCl or AgClBr having >=40mol.% Cl content. The pref. average thickness of the coat is <0.1mum. Thus, an emulsion capable of stabilizing a latent image and having satisfactory developability and high sensitivity is obtd.
