<p>Colour photographic material for the Ag dye bleach process consists of at least 2 multilayer combinations of (a) prefogged, low sensitivity Ag halide emulsion, rich in chloride, contg. a bleachable dyestuff, (b) opt. colour sensitised, high-sensitivity Ag halide emulsion rich in bromide, and (c) intermediate or top coat. The colour of the dyestuff used in (a) corresponds to the sensitivity of (b). This high speed colour copying material has good lighfastness and moisture resistance and excellent sharpness. Since the image is free from irregularity in the thickness of the coating theoretically, the mfg. process is greatly simplified.</p> |
