    Abstract: A negative-working lithographic printing plate precursor is disclosed that can be developed on the press without going through a development processing step, and a method of lithographic printing is also disclosed that uses this negative-working lithographic printing plate precursor. Also disclosed are a negative-working lithographic printing plate precursor that can be developed by a water-soluble resin-containing aqueous solution and a method of lithographic printing that uses this negative-working lithographic printing plate precursor. A negative-working lithographic printing plate precursor is provided that exhibits an excellent fine line reproducibility in nonimage areas even when printing is performed using ultraviolet-curing ink (UV ink). Also provided is a negative-working lithographic printing plate precursor that exhibits an excellent combination of fine line reproducibility and printing durability and that resists the production of scum during on-press development. The negative-working lithographic printing plate precursor has a hydrophilic support and has thereon a photopolymerizable layer that contains a polymer compound that has the urea bond in the side chain position and a hydrophilic group. The method of lithographic printing uses this negative-working lithographic printing plate precursor.
