Abstract
A carrier or substrate for a photoconductor to be used for the formation of an electrophotographic recording element, particularly an imaging drum for an electrophotographic printing press, wherein the carrier is made of a metal or a metal alloy, preferably of aluminum, is prepared wherein the surface of the carrier supporting the photoconductor, used to form a barrier layer, is oxidized, preferably by etching and/or anodizing. The oxidized surface of the barrier layer is sealed with a sealing material following oxidation, and a preservative or impregnating agent is used as the sealing material.

Method for preparing a carrier or substrate for a photoconductor for the formation of an electrophotographic recording element, particularly an imaging drum for an electrophotographic printing press, wherein the carrier is made of a metal or a metal alloy, preferably of aluminum, the method comprising the steps of:
- oxidizing the surface of the carrier supporting the photoconductor that is used to form a barrier layer, etching and/or anodizing, preferably to a barrier layer thickness of approximately 0.05 μm to approximately 1.5 μm, and following oxidation, sealing the oxidized surface of the barrier layer with a cold, water-based sealing material, including a melamine resin and/or aminoplastic resin as a preservative or impregnating agent.
