Preparation of a chloride rich tabular grain silver halide emulsion.

摘要

A tabular grain silver halide emulsion is disclosed, and a method for its preparation, said emulsion containing at least 95 mole %, preferably 100 mole % of chloride, characterized in that a compound providing complex iron(II) ions is present as dopant during grain formation. Preferably a crystal growth modifier is also present during grain formation. Preferred compounds providing complex iron(II) ions are potassium and sodium hexacyanoferrate(II).
