Abstract
A silver halide photographic element has a silver halide emulsion layer primarily containing tabular silver halide grains and a hydrophilic colloid layer, either of which contains a pigment with a maximum absorption wavelength of 570-650 nm dispersed in lipophilic droplets of a high-boiling organic solvent. The photographic element has a high sensitivity and high silver covering power, and is improved in the transmission and reflection blackness of image silver and staining of fluorescent intensifying screens.
Claims10
A silver halide photographic element comprising a support and one or more hydrophilic layers on the support including at least one silver halide emulsion layer containing silver halide grains, wherein
- tabular grains having an aspect ratio of at least 5 account for at least 50% of the total projected area of the silver halide grains in said silver halide emulsion layer,
- said silver halide emulsion layer or a hydrophilic colloid layer disposed above said silver halide emulsion layer contains a pigment having a maximum absorption wavelength between 570 nm and 650 nm, and
- said pigment is dispersed in lipophilic droplets formed of a water-immiscible high-boiling organic solvent having a boiling point of at least 140.degree. C.
