Abstract
In accordance with the present invention, there are provided water-developable photopolymerizable compositions useful for the preparation of printing plates. Printing plates prepared employing invention compositions have excellent form stability, thereby enabling such plates to be handled without the need for excessive care. Once photopolymerized, printing plates of the invention have excellent physical properties, enabling their use in many very demanding commercial applications, e.g., commercial flexographic printing. Such applications require the photopolymerized resin to have excellent water resistance (so that exposure to water-based inks does not significantly alter resin properties), as well as high durability (so that the physical contacting associated with the printing process does not significantly degrade resin properties).
