Abstract:
1. A radiation-sensitive composition comprising: a radically polymerizable component, an initiator composition capable of generating radicals sufficient to initiate polymerization of said radically polymerizable component upon exposure to imaging radiation, and a polymeric binder, wherein said polymeric binder has a hydrophobic backbone and comprises both the following a) and b) recurring units, or b) recurring units alone: a) recurring units having pendant cyano groups attached directly to said hydrophobic backbone, and b) recurring units comprising poly(alkylene oxide) segments, and wherein said radically polymerizable component is derived from the reaction of a multifunctional isocyanate compound and one or more urea urethane (meth)acrylates or urethane (meth)acrylates comprising carboxy groups.
