PURPOSE:To provide a wider photosensitive region and higher sensitivity and to improve sharpness, color resolving power, etc. by incorporating at least one layer to which a specific methine dye is added into the titled element. CONSTITUTION:At least one layer into which the methine dye expressed by the formula (n is 0, 1, m is 1, 2. R1 is a (un)substd. alkyl, R2-R4 are respectively H, alkyl, alkoxy, hydroxy, (un)substd. amino, halogen atom, R2 and R3, R3 and R4 or R2 and R4 may from a condensed 6-membered ring. Z1 and Z2 are respectively 5- or 6-membered ring formaing atom groups and the ring thereof may form a substituent or may be condensed with other rings. L1, L2 are (un) substd. methine) is incorporated is disposed on the photosensitive photographic element consisting of a base, silver halide and other layer. Such dye has the function as a sensitizing dye or filter dye, irradiation dye or anti-halation dye. The spectral region is expanded and the sensitivity is improved by using such dye. In addition, the generation of stains after the developing process is suppressed and the sharp image is obtd. |
