Abstract
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.
