Abstract
Abstract A light-sensitive material package unit having an exposure function is disclosed, in which said light-sensitive material comprises a support having provided thereon at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing a magenta coupler, and at least one blue-sensitive silver halide emulsion layer containing a yellow coupler; at least one of said light-sensitive emulsion layers is composed of at least two layers being substantially the same in color sensitivity and different in sensitivity; and said light-sensitive emulsion layer composed of at least two layers contains a compound represented by formula (I) A--L.sub.1).sub.b Z.sub.1 (I) wherein A represents a component capable of releasing --(L 1 ) b Z 1 upon reacting with an oxidation product of a color developing agent; L 1 represents a timing group; Z 1 represents a residual group having active development inhibitory property; and b represents 0 or 1. The package unit exhibits improved exposure latitude and improved image sharpness.
