  • Patent number: 4291109
    Abstract: Disclosed herein is a method and apparatus for producing color transparencies on a recording element comprising an additive color filter screen having disposed thereon a coating of a visible light-transmissive, invisible light-sensitive, silverless material, preferably a diazo or vesicular material. The method comprises the steps of imagewise exposing a panchromatic auxiliary layer, e.g. a photoconductive layer, to a multicolored object, such exposure being made through the recording element of the invention. This step acts to produce in the auxiliary layer a monochrome image containing color image information of the multicolored object. Next, the silverless material is exposed to invisible actinic radiation, such exposure being made through the monochrome image formed in or on the panchromatic auxiliary layer. This step serves to transfer the color image information from the auxiliary layer to the silverless layer of the recording element.
