PURPOSE:To form the titled material which has the high sensitivity, and comprises a blue sensitive layer having the excellent coloring property by incorporating a specified dye in the titled material, and a specified coupler in the blue sensitive layer, respectively. CONSTITUTION:The titled material contains at least one kind of the dye shown by formula I, and the coupler shown by formula II in the blue sensitive layer, respectively. In the formulas, R1 and R2 are each -COOR5, R3-R6 are each hydrogen atom., Q1 and Q2 are each aryl group, X1 and X2 are each a single bond or a divalent bonding group, Y1 and Y2 are each sulfo group, L1-L3 are each methine group, (m1) and (m2) are each 1 or 2, (n) is 0-2, (p1) and (p2) are each 0-4, (s1) and (s2) are each 1 or 2. Thus, the titled material which has the excellent image sharpness and the high sensitivity and the excellent coloring and preservation in the blue sensitive layer, is obtd. |
