Abstract
Oligomeric resins are crosslinkable by polymerization, soluble or dispersible in aqueous alkaline solutions, preferably contain more than 2 (meth)acryloyl groups and free carboxyl groups and are prepared by a special process. Photosensitive, photopolymerizable and crosslinkable recording materials for optical information fixing are based on these oligomeric resins, and lithographic printing plates are produced by a process in which the novel photosensitive recording materials are used.
