Abstract

PURPOSE: To produce the internal latent image type emulsion of core/shell type of high photographic sensitivity and less fog by chemically sensitizing the emulsion through the use of water soluble gold compounds in the presence of the specific compounds.
CONSTITUTION: The compound of the formula [R1 thru R4 respectively (un) substituted alkyl, alkenyl, aryl; heterocyclic imidazolidine thion of 5 to 6 members may be formed by coupling of R1 and R2, R2 and R3, R3 and R4], e.g., tetramethyl thiourea, is combined with water soluble gold compounds. This compound is used preferably at about 1×10-3 to 1×10-2 moles per mole of silver halide. In addition, this compound poses no problems in pollution, is easy to handle and is effective for increased sensitivity at the gold sensitization.
