ABSTRACT OF THE DISCLOSURE An original information carrier is disclosed which comprises a recording layer applied to a carrier material. The recording layer contains information in the form of a relief image which is made of relief part- images which border on one another without overlapping. The recording layer further comprises a relief grating of different grating depths superimposed over the areas of said roller part-images. A process for producing an information carrier is disclosed which comprises exposing a recording layer through separate color separation originals, exposing the layer to a grating pattern, and developing the exposed recording layer. A process for forming a matrix containing the in- formation stored on an information carrier is disclosed which comprises forming a layer of material on the original informa- tion carrier and then separating the layer from the carrier. The separated layer of material may then be used to make additional copies of the original relief image by contact- ing it with transparent deformable materials. Also, an information carrier which is a copy of an original information carrier is disclosed which is made of a deformable material having the relief gratings and part- images of the original embossed therein.
