Abstract
Substrates for imageable elements are disclosed. The substrates comprise, in order, an aluminum or aluminum alloy support, a silicate layer, and a layer of interlayer material. The interlayer material is a co-polymer that comprise (1) phosphonic acid groups and/or phosphate groups and (2) acid groups and/or groups that comprise ethylene glycol or polyethylene glycol side chains. Imageable elements that comprise an imageable layer over the interlayer material are useful as lithographic printing plate precursors.
