PREPARATION OF SILVER HALIDE EMULSION
PURPOSE: To produce an emulsion having an improved sensitivity/grain ratio. CONSTITUTION: A silver halide emulsion containing till 20mol.% AgI is prepared by precipitating the silver halide emulsion A containing up to 100mol.% AgI and adding the silver halide emulsion B containing up to 40mol.% AgI...

Zusammenfassung: | PURPOSE: To produce an emulsion having an improved sensitivity/grain ratio. CONSTITUTION: A silver halide emulsion containing till 20mol.% AgI is prepared by precipitating the silver halide emulsion A containing up to 100mol.% AgI and adding the silver halide emulsion B containing up to 40mol.% AgI under the presence of at least two compounds among imidazole. histidine and other five- or six-membered ring heterocyclic compd. |
