Abstract: A layered information record contains superimposed frames of information wherein a first frame contains luminance information of a scene as density variations of a cyan dye. A second frame superimposed on the first frame contains color encoded chrominance information as density variations of a yellow dye. In a system for playing back the layered information record, white light is projected through the superimposed first and second frames of information and viewed through a red filter for extracting the monochromatic luminance information and a blue filter for extracting the monochromatic color encoded chrominance information.
