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.
