A singe- or multilayer lithographic printing plate precursor comprises on a substrate a radiation-sensitive coating that comprises a copolymer soluble or dispersible in aqueous alkaline solution and comprising (meth)acryl recurring units, imide recurring units, and amide recurring units derived from corresponding ethylenically unsaturated polymerizable monomers; the copolymer provides increased chemical resistance for the lithographic printing plate precursors which can be negatively or positively working.
