Abstract
Abstract Autostereographic prints are made by photographic means in which a transparent support having one surface lenticulated carries on the opposite surface at least one radiation-sensitive layer such as a silver halide emulsion layer over which the sensitive layer farthest from the support is coated a highly reflective layer such as one containing titanium dioxide pigment, which is preferably permeable to the processing baths required to process the radiation-sensitive layer.
