Zusammenfassung:	A film with a repeating color filter dot pattern on one side and an opaque coating such as bismuth metal on the other side, serves as a medium for reproducing color transparencies. Laser light having the same frequency as the dot color is directed through those dots constituting the desired image. The metallic coating behind each such dot is thereby evaporated, leaving the dot color unaffected. Illumination from the metal side produces the desired projected image. The image may also be viewed in reflected light by placing the film against a white background sheet.
