<P>PROBLEM TO BE SOLVED: To provide a photosensitive planographic printing plate having excellent competency for feeding to a plate setter, high storage stability and excellent sensitivity, plate wear and contamination resistance. <P>SOLUTION: The photosensitive planographic printing plate has a photosensitive layer and a protective layer on a hydrophilic support, wherein the photosensitive layer contains a compound having an ethylenically unsaturated double bond and a polymer binder, and the protective layer is formed by depositing two or more layers of a water-soluble resin. The invention provides a stack of the above photosensitive planographic printing plates with a slip paper inserted between the plates. Preferably, one layer in the protective layer has an oxygen permeability of 1.0 to 20 cm<SP>3</SP>/m<SP>2</SP>day, and the coefficient of dynamic friction between the surface of the protective layer and the slip sheet or the back face of the photosensitive planographic printing plate is in the range of 0.2 to 0.7. <P>COPYRIGHT: (C)2007,JPO&INPIT |
