摘要： A light sensitive composition which is capable of photopolymerization which includes a photopolymerizable compound a free radical generating component and a benzanthrone or substituted benzanthrone which substantially prevents photopolymerization when the light sensitive composition is exposed to actinic radiation below a threshold amount but permits photopolymerization when the light sensitive composition is exposed to actinic radiation above a threshold amount. This achieves a gate effect which eliminates or decreases unwanted partial exposure in the nonimage areas and hence improves reproduction quality.

摘要： Embodiments of the present invention involve printing members that avoid ablation imaging mechanisms and, as a result, crosslinked topmost layers. Topmost layers as described herein exhibit good thermal stability and durability during printing, but can be cleaned (and thereby removed from unimaged areas) with water or aqueous cleaning fluids following imaging. It is found, in some embodiments, that the viability of certain topmost layers can be critically dependent on the nature of the underlying substrate, e.g., in terms of texture and/or surface volume.
