Abstract (en)

Disclosed is a light-sensitive silver halide photographic material comprising: a support; a first light-sensitive unit comprising a first light-sensitive layer and a first non-light-sensitive layer; and a second light-sensitive unit comprising a second light-sensitive layer and a second non-light-sensitive layer, the first light-sensitive unit being provided on one side of the support and the second light-sensitive unit being provided on the other side of the support, wherein a sensitivity of the first light-sensitive unit when exposure is effected only from the one side (sA), a sensitivity of the second light-sensitive unit when exposure is effected only from the other side (sB) and a sensitivity of the first light-sensitive unit when exposure is effected only from the other side (sA') satisfy the following equations: (I) sA/sA' > 4.0 (II) sA/sB = 1.5 to 20 p
