摘要:
The present invention provides a silver halide color photographic photosensitive material that includes coupler-containing sensitive emulsion layer units on a support. Each of the photosensitive emulsion layer units are constituted of at least two photosensitive emulsion layers having sensitivities which are different from each other. An emulsion layer of the highest sensitivity among the at least two photosensitive emulsion layers contains at least one silver halide emulsion in which tabular silver halide grains with an average aspect ratio of 3 or more substantially including dislocation lines account for 50% or more of the total projected areas. Photosensitive emulsion layers other than the emulsion layer of the highest sensitivity consist of a silver halide emulsion containing silver halide grains that account for 70% or more of the total projected areas and include host grains that satisfy a specific aspect ratio condition and epitaxially joined protrusions.
