Abstract
Improved compositions comprising solvent-soluble, negative-acting or positive-acting light-sensitive diazonium compounds and solvent-soluble unsaturated monomers which are the products of about two equivalents of an organic diisocyanate with about one equivalent of an active hydrogen-containing organic compound, e.g., an alcohol or amine, preferably a polyol, which products are subsequently reacted with an unsaturated compound which contains an active-hydrogen, preferably in a hydroxyl group, available to react with the remaining isocyanate groups. The compositions can be coated onto suitable base sheet materials to form presensitized lithographic printing plates, proofs for multi-color printing, visual aids, printed circuits and the like.
