Beschreibung
Zusammenfassung:	A radiation-polymerizable mixture is described which comprises a) a saturated polyurethane containing carboxyl groups and repeating urea groups as binder, b) a radical-polymerizable compound containing at least one terminal olefinic double bond and having a boiling point above 100 DEG C. at normal pressure, and c) a compound or combination of compounds capable of initiating the polymerization of compound (b) on exposure to actinic radiation. The mixture can be developed with purely aqueous developers and yields lithographic printing plates with high photosensitivity, low stickiness and high print runs.
