On a substrate, comprising a copolymer that is soluble or dispersible in an aqueous alkaline solution and comprises (meth) acrylic repeating units, imide repeating units, and amide repeating units derived from the corresponding ethylenically unsaturated polymerizable monomers. A single-layer or multi-layer lithographic printing plate precursor, wherein the copolymer provides enhanced chemical resistance to a lithographic printing plate precursor that can be negative or positive body. |
