| titleOfInvention | Silver halide photographic light-sensitive material with improved gradation balance |
| abstract | A silver halide photographic light-sensitive material which is prevented from softening in gradiation of the toe proportion on the resultant characteristics curve during the storage of the material. The photographic material comprises a support having thereon at least one silver halide emulsion layer, and contains a magenta coupler represented by the following formula M-1 and at least one surface active agent having in the molecule thereof at least two groups selected from the group consisting of a carboxy group and salt thereof, a sulfonic group and a salt thereof and a salt of sulfric ester group. ##STR1## wherein Z represents a group of nonmetal atoms necessary for forming a nitrogen-containing heterocycle which may have a substituent group; X represents a hydrogen atom, or a group capable of being split off upon the reaction with the oxydized product of a color developing agent; and R represents a hydrogen atom or a substituent. |
