Abstract
The invention is directed to a process for forming a chromogenic photographic heat-transferable non-aqueous dye-diffusion-transfer photographic element comprising the steps of: providing, separately, a melt comprising a spectrally dye-sensitized silver halide emulsion and a dry diffusion transfer facilitating thermal solvent; mixing said spectrally dye sensitized silver halide emulsion melt and said dry diffusion transfer facilitating thermal solvent with a mixing means to create a mixed melt; providing a coating substrate; coating said mixed melt on said substrate to form a coated photographic element, wherein said coating takes place less than about 10 minutes after mixing. The heat-transferable photographic element thus formed has improved photographic sensitivity and increased sensitometric uniformity.
