Abstract
The production and use of indicia-bearing anodized layers from which the backing metal has been removed as transparent or translucent elements in articles in which the layer may be laminated to a clear or translucent layer so that the information contained in the anodized layer can be read by direct illumination rather than by reflected light. The information in the pores of this anodized article is preferably in the form of a metal image and of a metal selected from the group consisting of silver, gold, platinum and palladium which is preferably silver and which may be intensified by the electroless deposition of other metals thereon, such metals being selected from the group consisting of nickel, cobalt, iron, copper, chromium, gold, silver, platinum, palladium and mixtures thereof. Products of special interest include edge lighted panels, microfilm, microfiche, photomasks, and printed circuits.
