Method of manufacturing embossed articles of preset configuration
First Claim
1. A method of manufacturing embossed articles of a preset configuration with the use of material sensitive to actinic electromagnetic and corpuscular radiation consisting essentially of the following operations:
- application of a metal layer to a backing;
coating said metal layer with a barrier layer consisting of matter chemically different from that of said metal layer;
coating said barrier layer with a layer of inorganic matter containing a substance selected from the group consisting of sulfur, selenium, and selenium and halogen, said inorganic matter chemically different from the barrier layer and will react chemically with said metal layer in the absence of the barrier layer to form the products of interaction whose physical and chemical properties differ from those of said metal layer and the layer of inorganic matter;
wherein the barrier layer is of sufficient thickness in the range of 20-300 A to permit said chemical interaction only in the presence of actinic electromagnetic or corpuscular radiation;
projecting a pattern of a preset configuration on said applied layers;
exposure;
removal of unnecessary portions of said layers until an embossed article of a preset configuration is produced.

Abstract
A method of manufacturing embossed articles of a preset configuration utilizing a material sensitive to electromagnetic and corpuscular radiation. The method consists in coating a backing with a layer of metal, applying a barrier layer to the metal layer, coating the barrier layer with a layer of inorganic matter capable of interacting chemically with the metal layer and forming the products of interaction whose physical and chemical properties differ from those of the metal layer and the layer of inorganic matter, in projecting a picture of a preset configuration on the applied layers, exposure, and in the removal of the unnecessary portions of the layers until an embossed article of a preset configuration is produced. The barrier layer is made of a material different from the layer of metal and the layer of inorganic matter and inert with respect to the metal layer and the layer of inorganic matter in absence of electromagnetic and corpuscular radiation. The thickness of the barrier layer is made sufficient to prevent chemical interaction between the metal layer and the layer of inorganic matter in absence of electromagnetic and corpuscular radiation and permitting such interaction in presence of electromagnetic and corpuscular radiation.
