Abstract (en)
[origin: EP0158261A2] 1. Photographic recording material having at least one yellow filter layer and at least one blue-sensitive, one green-sensitive and one red-sensitive layer, at least one of which is split into at least three partial layers of different sensitivities, the partial layers being arranged in such a manner that, on imagewise exposure, the light exposes at least one partial layer before passing through the yellow filter layer and expose at least one partial layer after it has passed through the yellow filter layer, characterized in that - based on at least one layer - the ratio K/A in the most highly sensitive partial layer is greater than that in the next most sensitive partial layer, K being the molar quantity of the colour-producing coupler, calculated as a 4-equivalent coupler, and A being the molar quantity of the light-sensitive silver halide.
