Imageable elements, useful as on press developable lithographic printing plate precursors, are disclosed. The elements comprise an imageable layer over a substrate and an one or more adhesion promoting ingredients. The imageable layer comprises a polymerizable compound and a polymeric binder. The adhesion promoting ingredients are titanium chelate and/or co-polymers of a monomer having a polethylene oxide side chain with a monomer having either an acidic group or an anhydride group that has been ring opened to form an acidic group or groups.

Adhesion promoting ingredients for on-press developable lithographic printing plate precursors

Substrates for lithographic printing plate precursors and lithographic printing plate precursors are disclosed. The substrates comprise an aluminum or aluminum alloy support and the a layer of interlayer material on the support. The interlayer material is a co-polymer that comprise (1) acid groups and/or phosphonic acid groups, and (2) silyl groups substituted with three alkoxy and/or phenoxy groups. The lithographic printing plate precursors additionally comprise an imageable layer over the interlayer.
