A substrate useful for forming lithographic printing plate precursors includes a metal or polymer support and an interlayer comprising a trialkoxysilyl polyethylene glycol acrylate having the following Structure (I): wherein R1 and R2 are independently hydrogen or C1 to C6 alkyl, C1 to C6 alkenyl, C1 to C6 alkoxy, C1 to C6 acyl, C1 to C6 acyloxy, phenyl, halo, or cyano groups, or R1 and R2 together can form a cyclic group, R3 is hydrogen, or a C1 to C6 alkyl, phenyl, halo, or cyano group, R4 and R5 are independently hydrogen or methyl groups, R6 is hydrogen or a C1 to C12 alkyl group, X1 is —O— or —NR— wherein R is hydrogen or an alkyl or aryl group, X2 is —NR′— wherein R′ is hydrogen or an alkyl or aryl group, m is an integer of from 15 to 200, and n is an integer of from 1 to 12. The lithographic printing plates can be negative-working and particularly useful for on-press development and have a sulfuric acid-anodized aluminum support.
