ABSTRACT:
Photographic dye image transfer film units are disclosed employing negative working high aspect ratio tabular grain silver halide emulsions. The dye image transfer film units can achieve a variety of advantages, such as reductions in silver coverage with diminished reductions in speed, diminished increases in minimum density levels, allowing a transferred image to be rapidly accessible for viewing, and producing lower minimum densities and higher maximum densities for a given time of development, and greater image discrimination. Improvements in other photographic characteristics (such as sharpness), advantageous layer order arrangements, and reduction or elimination of various layers, such as yellow filter layers and scavenger interlayers can be obtained also.
