A water-less PS plate for use in making a water-less lithographic printing plate comprises, on a substrate, a photopolymerizable light-sensitive layer and a silicone rubber layer in this order, wherein the light-sensitive layer is formed from a photopolymerizable light-sensitive composition which contains an urea bond-containing polyurethane as a binder. According to the present invention, there is obtained a water-less PS plate having good resistance to scratch and high printing durability. Moreover, the resulting light-sensitive layer does not get sticky, the light-sensitive layer of the non-image portions is not peeled off during the printing operations, and the lithographic plate shows good dyeability and plate-examination property.
