Process for preparing image-bearing plates

摘要

Disclosed is a process for preparing an image-bearing plate for use in a lithographic printing plate, a photoresist or the like. The process comprises, after imagewise exposing a light-sensitive plate comprising a support having provided thereon a light-sensitive layer comprising a compound capable of producing an acid upon irradiation with actinic rays, a compound having at least one acid-decomposable group, and an alkali-soluble resin, treating the exposed plate with hot water of at least 25 DEG C. for a period of at least 10 seconds, prior to development. It is possible to achieve high sensitivity regardless of the interval between the exposure and the development.
