Abstract (en)

[origin: EP0580029A2] A colour-photographic recording material of camera sensitivity having 2 or 3 green-sensitive layers, 2 or 3 red-sensitive layers and 2 or 3 blue-sensitive layers, where the blue-sensitive layers are installed further from the support than are the green- and red-sensitive layers; the low-blue-sensitive layer or the low- and middle-blue-sensitive layer is built up from silver halide emulsions containing at least 50 mol% of AgCl, and the total amount of silver in the material has been set, as a function of sensitivity, to a value which satisfies the following relationship: amount of Ag = 0.27 . E-X, where the amount of silver is determined in g/m<2>, X has a value between 1.9 and 3.8, and E is the sensitivity in DIN units, is distinguished by improved sharpness.
