Abstract
A water developable printing plate is provided with a photopolymerizable system as a latex comprising a water soluble diazopolymer reaction product of a diazoaryl amine and an aldehyde and an aqueous cationic or nonionic dispersion of a water insoluble polymer. The inclusion of a water miscible organic solvent improves the shelf-life of the photopolymerizable system and the printing plate especially under high humidity conditions.
