Abstract
A single manufacturing pass for manufacturing a multilayered self-organized coating onto a substrate to provide all of the functions usually provided in multiple-pass coatings for manufacturing an infrared imageable offset lithographic printing plate; and a process whereby two or more polymeric materials that cannot usually co-exist in solution may be dissolved in suitably dilute solvent mixtures which, when coated onto a substrate and the solvents evaporated, deposit a continuous graduation of polymeric mixtures vertical to the substrate, caused by the self-assembly process.
