Abstract
A multilayered color photographic element contains a support having coated thereon photographic silver halide emulsion layers including at least three layers each having the same spectral sensitivity but having, respectively, the most, mid, and least light sensitivity wherein the most and mid sensitive layers are contiguous and the most sensitive layer is extremely starved of image dye-forming coupler.
Claims20
A multilayered color photographic element comprising a support having coated thereon photographic silver halide emulsion layers said layers including at least three layers each having the same spectral sensitivity but having, respectively, the most, mid, and least light sensitivity wherein the most and mid sensitive layers are contiguous and the most sensitive layer is substantially free of image dye-forming coupler.
A multilayer photographic element comprising a support having coated thereon photographic silver halide emulsion layers the element being comprised of a plurality of blue sensitive silver halide emulsion layers, with one of the blue sensitive layers being more sensitive than another less blue sensitive layer, at least three red sensitive silver halide emulsion layers having a first or most red sensitive layer being more sensitive than a second or mid red sensitive layer which is more sensitive than a third or least red sensitive layer, a plurality of green sensitive silver halide emulsion layers with one of the green sensitive layers being more green sensitive than another or least green sensitive layer, the layers arranged with
- (a) the least red sensitive layer being a photographic emulsion layer closest to the support
- (b) the least green sensitive layer adjacent said least red sensitive layer
- (c) the mid red sensitive layer adjacent said least green sensitive layer and contiguous said most red sensitive layer and
- (d) the most red sensitive layer being a coupler starved layer and being free of cyan image dye-forming coupler.
