Abstract

Photographic image transfer film units are disclosed employing high aspect ratio tabular grain silver halide emulsions comprising a support, at least one emulsion layer located on said support containing a dispersing medium and radiation- sensitive silver halide grains, and an image receiving layer. These units are characterized in that at least 50 percent of the total projected area of said radiation-sensitive silver halide grains of at least said one emulsion layer is provided by tabular silver halide grains having a thickness of less than 0.5 micrometer, a diameter of at least 0.6 micrometer, the diameter of a grain being defined as the diameter of a circle having an area equal to the projected area of said grain, and an average aspect ratio of greater than 8:1, which aspect ratio is defined as the ratio of grain diameter to thickness. The units allow the transferred image to be rapidly accessible for viewing, higher interim contrasts to be produced as a function of elapsed time of development, and improvements in photographic characteristics (such as sharpness), reduction in silver coverages, advantageous layer order arrangements, and reduction or elimination of various layers, such as yellow filter layers and scavenger interlayers.
