Multilayer thermally imageable elements useful as lithographic printing plate precursors are disclosed. The imageable elements comprise a substrate, an underlayer over the substrate, and a top layer over the underlayer. The top layer contains a polymer containing anhydride groups. This polymer is present in the top layer in an amount of at least 60% based on the dry weight of the layer. The imageable elements have excellent resistance to press room chemicals.
