A method for making a pattern on a support member by projecting an actinic image of the pattern to be reproduced on an electromagnetic-radiation-sensitive element consisting of a support member or substrate having an adhering metallic layer thereon, the metallic layer, as defined herein, being in turn coated with an adhering overlayer of an inorganic material capable of reacting, when exposed to electromagnetic actinic radiation, with the metallic layer. After exposure, the overlayer is peeled, thereby removing from the support member or substrate portions of the metallic layer corresponding to the nonradiated areas of the element, while the radiated areas of the element remain adhering to the support member or substrate. Alternately, after exposure of the element to a pattern forming image, the element is uniformly exposed to actinic radiation for a time sufficient to decrease the adhesion between the metallic layer and the overlayer, and the two layers are separated or peeled away from each other such that there is formed a pattern upon the support member or substrate.
