<p>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 relief 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 information stored on an information carrier is disclosed which comprises forming a layer of material on the original information 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 contacting 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.</p> |
