METHOD FOR THE ELECTROPHORETIC DEPOSITION OF RADIATION-SENSITIVE COATINGS ON METALLIC BASES, AND USE OF THE COATED MATERIAL AS AN OFFSET PRINTING PLATE

摘要

Light sensitive compounds are deposited onto a hydrophilized metal substrate, which is preferably aluminum, by means of a direct current electromotive force. The light sensitive component is dissolved in a current carrying solvent. Cathodic, hydrophilized, aluminum is passed through the solution and the EMF applied. The result is a light sensitive coating on the hydrophilized substrate surface.
