Abstract
Process for the storage of information in an organic recording layer which, as the result of local treatment of its surface with an organic solvent in accordance with the shape of the information to be marked can alter its absorption spectrum and/or its photoconductivity in such a way that information is produced and stored respectively at the treated areas of this layer. The information thus stored can be read off visually, by means of a micro-reader or by means of an incorporated electrode system.
