<P>PROBLEM TO BE SOLVED: To provide a photosensitive negative lithographic printing plate having high sensitivity, high preservability under a high humidity condition, and high printing durability. <P>SOLUTION: The photosensitive negative lithographic printing plate includes a hydrophilic layer, a photosensitive layer containing photosensitive polymer, and an over layer at least in this order on a plastic film support. The photosensitive layer contains organic fine particles having an average particle diameter of 80% or smaller of the sum of the thicknesses of the photosensitive layer and the over layer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
