Abstract
This invention provides a support for a lithographic printing plate, and an original form of a heat-sensitive lithographic printing plate, which comprises a hydrophilic film formed on a metallic base whose surface has been roughened, said hydrophilic film having a heat conductivity of 0.05–0.5 W/(m·K) in the direction of its film thickness, which when used as the development on machine type, exhibits good on-press, or good non-treatment developability, a high sensitivity, a long press life and a preferable stain resistance and ink removal property upon printing and which, when used as a conventional thermal positive or negative type, makes efficient utilization of heat for the formation of image, has a high sensitivity and exhibits a long press life and a good stain resistance in a nonimage area, wherein the non-treatment in which the development is not performed.
