Abstract: A structured surface is formed with the method of the present invention. The method of making this structured surface includes the steps of applying an ablatable radiation sensitive coating on the major surface of the substrate, and exposing the ablatable radiation sensitive coating to radiation such that exposed portions of the ablatable radiation sensitive coating ablate from the substrate to form a structured surface. The structured surface then includes a substrate and a pattern of structures framed by at least one separation bank. The method may also include the steps of depositing a flowable material on to the structures and the separation bank to form a pattern of flowable material in the structures.

Abstract: The present invention relates to a polymerizable coating composition suitable for the manufacture of printing plates, which may be developable on-press. The coating composition comprises (i) a polymerizable compound and (ii) a polymeric binder comprising polyethylene oxide segments, wherein the polymeric binder is selected from the group consisting of at least one graft copolymer comprising a main chain polymer and polyethylene oxide side chains, a block copolymer having at least one polyethylene oxide block and at least one non-polyethylene oxide block, and a combination thereof. The invention is also directed to an imageable element comprising a substrate and the polymerizable coating composition.
