| description | PURPOSE:To make a magenta developing dye similar in spectral characteristics to magenta ink over the range from a low density area to a high density area by incorporating a yellow developing coupler having a specified relative coupling rate, specified compds. and a magenta developing coupler into a silver halide emulsion layer. CONSTITUTION:A two-equiv. yellow developing coupler having 0.5-2.0 relative coupling rate, a magenta developing coupler represented by formula I and compds. represented by formula II, III are incorporated into a green-sensitive internal latent image type silver halide emulsion layer. In the formula I, R10 is H or a substituent, Y4 is H or a releasable group and each of Za-Zc is methine, substd. methine, etc. In the formulae II, III, Q is a group of atoms required to form a 5- or 6-membered hetero ring, L is H, O or other divalent combining group and R is an org. group contg. amino, thio-ether, etc. A magenta developing dye can be made similar in spectral absorption to magenta ink. |
