Abstract
Thermally imageable, positive working, multilayer imageable elements useful as lithographic printing plate precursors are disclosed. The elements comprise a substrate; an underlayer over the substrate; a top layer over the underlayer, and a photothermal conversion material. The top layer comprises a binder and an ionic liquid. A preferred binder is poly(methyl methacrylate).
