Claims
- 1. The color photographic recording material consisting of
- (a) a layer support having applied to it a plurality of layers including light-sensitive layers and including
- (b) three green-sensitive silver halide emulsion component layers of different speed each having associated with it a magenta-forming coupler including a least-sensitive green-sensitive silver halide emulsion layer, a more-sensitive green-sensitive silver halide emulsion layer having the ratio of silver halide to coupler higher than in the least-sensitive green-sensitive layer and arranged further from said layer support than said least-sensitive green-sensitive layer and a most-sensitive green-sensitive silver halide emulsion layer having a ratio of silver halide to coupler higher than in the more-sensitive green-sensitive layer and arranged further from said layer support than said more-sensitive green-sensitive layer;
- (c) two red-sensitive silver halide component layers of different speed each having associated with it a cyan-forming coupler, including a less-sensitive red-sensitive silver halide emulsion layer, and a more-sensitive red-sensitive silver halide emulsion layer having a ratio of silver halide to coupler higher than in the less-sensitive red-sensitive layer;
- (d) at least one non-light-sensitive yellow filter layer is located further removed from the layer support than any one of said red-sensitive layers, and green-sensitive layers, and
- (e) one or more blue-sensitive silver halide emulsion layers each having associated with it a yellow-forming coupler and being located further removed from the layer support than said yellow filter layer;
- wherein the improvement comprises each of the green-sensitive layers being arranged further away from the layer support than the less-sensitive red-sensitive layer, the more-sensitive red-sensitive layer is located between the more-sensitive green-sensitive layer and the most-sensitive green-sensitive layer,
- whereby said more sensitive red-sensitive layer being less adjacent the layer support than said more-sensitive green-sensitive layer and said less-sensitive red-sensitive layer.
- 2. The color photographic recording material consisting of
- (a) a layer support having applied to it a plurality of layers including light-sensitive layers and including
- (b) three green-sensitive silver halide emulsion component layers of different speed each having associated with it a magenta-forming coupler including a least-sensitive green-sensitive layer silver halide emulsion, a more-sensitive green-sensitive silver halide emulsion layer, having the ratio of silver halide to coupler higher than in the least-sensitive green-sensitive layer and arranged further from said layer support than said least-sensitive green-sensitive layer and a most-sensitive green-sensitive silver halide emulsion layer having a ratio of silver halide to coupler higher than in the more-sensitive green-sensitive layer and arranged further from said layer support than said more-sensitive green-sensitive layer;
- (c) two red-sensitive silver halide component layers of different speed each having associated with it a cyan-forming coupler, including a less-sensitive red-sensitive silver halide emulsion layer, and a more-sensitive red-sensitive silver halide emulsion layer having a ratio of silver halide to coupler higher than in the less-sensitive red-sensitive layer;
- (d) at least one non-light-sensitive yellow filter layer located further removed from the layer support than any one of said red-sensitive and green-sensitive layers, and
- (e) one or more blue-sensitive silver halide emulsion layers each having associated with it a yellow-forming coupler and being located further removed from the layer support than said yellow filter layer;
- wherein the improvement comprises each of the green-sensitive layers being arranged further away from the layer support than the less-sensitive red-sensitive layer the more-sensitive red-sensitive layer is located between the least-sensitive green-sensitive layer and the more-sensitive green-sensitive layer,
- whereby said more-sensitive red-sensitive layer being less adjacent the layer support than said least-sensitive green-sensitive layer and said less-sensitive red-sensitive layer.
- 3. A material as claimed in claim 2 in which the difference in effective sensitivities of layers producing the same component color image is from 0.2 to 1.0 relative log I.times.t units.
- 4. A material as claimed in claim 1 in which the difference in effective sensitivities of layers producing the same component colour image is from 0.2 to 1.0 relative log I.times.t units.
