Surface latent image type silver halide photographic emulsion
摘要:
Disclosed herein is a surface latent image type silver halide photographic emulsion containing silver halide grains which have been formed in the presence of a tellurium compound which forms silver telluride in silver bromide emulsion at a pseudo-first-order reaction rate constant k of 1 × 10⁻⁷ min⁻¹ to 1 × 10⁻¹ min⁻¹, and in which tellurium ions have been thereby doped. Also disclosed is a surface latent image type silver halide photographic emulsion containing silver halide grains which have been formed by adding at least one labile tellurium compound selected from the group consisting of an organic compound containing tellurium single-bonded directly to S, SO, SO₂, Se, P=O or P=S, a cyclic organic compound having at least one tellurium atom and two or more chalcogen atoms in a ring, and an organic compound containing tellurium anions, and in which tellurium ions have been thereby doped.
