Abstract
In accordance with the present invention, water-developable photopolymerizable compositions useful for the preparation of durable printing plates capable of providing very high levels of resolution have been developed. Printing plates prepared employing invention compositions, once photopolymerized, have excellent physical properties, enabling their use in many very demanding applications, e.g., commercial letterpress and newspaper printing. Such applications require the photopolymerized resin to provide a sharp image and good durability after curing. Photopolymerization of invention resin yields a product with excellent physical characteristics, acceptable by letterpress printing standards. In addition, photopolymerization of invention composition provides a product which demonstrates sufficient toughness to be used for extended printing runs as required in such areas as metal decorating, newspaper, plastic packaging, business forms, and the like.
