Abstract
At least one layer of a conductive organic polymer, formed by electropolymerization on the anode in a two electrode cell, is bonded to a plastic substrate by compression with sufficient heat and pressure to cause it to bond to the substrate and release from the anode. Improved sandwich-type capacitive electronic discs having an information pattern in ultra thin outer conductive layers which are homogeneous and which contain no conductive particles are formed by this process by providing as the anode a mastering disc containing an information pattern which is the negative of the desired information pattern.
