PCT No. PCT/JP96/03296 Sec. 371 Date Oct. 27, 1997 Sec. 102(e) Date Oct. 27, 1997 PCT Filed Nov. 8, 1996 PCT Pub. No. WO97/17208 PCT Pub. Date May 15, 1997A directly imageable raw plate for waterless planographic printing plate, in which a heat insulating layer, heat sensitive layer and ink repellent layer are formed in this order on a substrate, comprising physical properties of 5 to 100 kgf/mm2 in initial elastic modulus and 0.05 to 5 kgf/mm2 in 5% stress as tensile properties of the heat sensitive layer or the heat insulating layer or the laminate consisting of both the layers. It can be suitably used also for large printing presses and web offset printing presses requiring high printing durability, and makes it possible to obtain an economically advantageous printing plate.
