    Abstract: A directly imageable raw plate for a waterless planographic printing plate, in which a heat insulating layer, heat sensitive layer and ink repellent layer are formed in that order on a substrate, comprising physical properties of 5 to 100 kgf/mm in initial elastic modulus and 0.05 to 5 kgf/mm 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.

    Abstract: An original form plate for a novel photosensitive lithographic form plate, in which development processing is simple, and which possesses a high ink repellent property without undergoing a desensitization and can use pure water as a dampening water, can be produced by using a lithographic form plate, in which (1) a non-printing area portion made of a hydrophilic swelling layer has an amount of water absorption of 1 to 50 g/m2 and a printing area portion has a less amount of water absorption than that of the non-printing area portion; (2) the non-printing area portion made of a hydrophilic swelling layer has an initial elastic modulus of 0.01 to 10 kg/mm2 and the printing area portion has a larger initial elastic modulus than that of the non-printing area portion; (3) the non-printing area portion made of a hydrophilic swelling layer has a water swelling rate of 10 to 2000 % and the printing area portion has a less water swelling rate than that of the non-printing area portion; or (4) the nonprinting area portion made of a hydrophilic swelling layer has a phase separation structure composed of at least two phases, that is, a phase, of which a main component comprises at least a hydrophilic polymer, and a phase, of which a main component comprises a hydrophobic polymer.

    Abstract: A lithographic printing plate, in which (1) the non-image area of a hydrophilic swellable layer is 1 to 50 g/m in water absorbability, and the water absorbability of the image area is less than that of the non-image area, (2) the non-image area of a hydrophilic swellable layer is 0.01 to 10 kg/mm in initial modulus, and the initial modulus of the image area is larger than that of the non-image area, (3) the non-image area of a hydrophilic swellable layer is 10 to 2000% in water swelling ratio, and the water swelling ratio of the image area is less than that of the non-image area, or (4) the hydrophilic swelling layer has a phase separated structure consisting of at least two phases; a phase mainly composed of a hydrophilic polymer and a phase mainly composed of a hydrophobic polymer, can be produced from a new photosensitive lithographic original plate simple in development treatment, highly repellent against ink even without being etched, and allowing the use of pure water as dampening water.
