ABSTRACT:
Color photographic products and processes are disclosed which provide a silver image in registration with a light-transmitting screen composed of minute optical elements, such as an additive color screen. The silver image is present in the developed silver halide emulsion layer which is maintained in registered relationship with said screen on a transparent support. Where the silver halide emulsion is negative-working, the silver image is a negative of the photographed subject, and the thus-obtained additive color negative image may be used to form full color positive images by printing onto subtractive color print material.
The undeveloped silver halide may be allowed to remain in the developed silver halide emulsion layer, or all or a portion thereof may be removed from the developed silver halide emulsion layer. If desired, undeveloped silver halide may be transferred to a silver-receptive stratum carried by a separate support to provide a positive silver transfer image which may serve as a "proof" of the developed negative image.
