Claims
- 1. A process for reproducing the information stored on an information carrier for use in zero order diffraction color projection which comprises the steps of:
- mounting a recording layer on a carrier;
- exposing said recording layer through individual color separation originals with energy density equal to that required to obtain individual projection colors to form relief part-images, each relief-part-image corresponding to a different projection color and adjoining the other ones without overlap and having a depth corresponding to one of the particular projection colors;
- exposing said recording layer to a grating pattern without intervening development to provide a structure in which the recording layer is exposed through to said carrier;
- developing said exposed recording layer;
- coating said recording layer with a thin, electrically conductive layer by vapor-depositing said conductive layer on the surface of the recording layer carrying the relief-part-images;
- electroplating a metal coating on said electrically conductive layer so that said metal coating represents the negative relief-part-images of said recording layer; and
- separating said metal coating from said recording layer to form a matrix.
