Abstract
A photocurable composition suitable for flexible photosensitive articles is prepared by reacting an acid-containing copolymer and a nitrogen-containing compound having polymerizable ethylenically unsaturated groups. The resulting composition can be used 'as is' or can be formulated with ethylenically unsaturated monomers and photoinitiators to prepare the flexible photosensitive articles, e.g. flexographic printing plates. The plates prepared from the photocurable composition are aqueous developable and sufficiently flexible and soft to be used for printing on flexible packaging surfaces.
