Methods for making a metallic relief pattern article by irradiating, according to the pattern to be reproduced, a radiation and heat sensitive element comprising essentially a layer of metal coated with an adhering overlayer of an inorganic material capable of interreacting with the metal when either exposed to electromagnetic radiation or exposed to heat. After exposure to electromagnetic radiation which causes a reduction in adhesion between the overlayer and the layer of metal, the element is stripped of the portions of the overlayer corresponding to the irradiated areas and is subsequently heated for causing an interreaction between the remaining portions of the overlayer and the layer of metal, consuming in depth and thus etching the metal of the layer of metal.
