ABSTRACT:
A radiation-polymerizable mixture is described comprising (a) a compound which has at least two terminal ethylenically unsaturated groups and which can form a crosslinked polymer by means of free radical initiated chain addition polymerization, (b) a polymeric binder, (c) a radiation-activatable polymerization initiator which can be activated by radiation, and (d) a compound which is thermally crosslinkable with the polymeric binder (b), with the polymerization product of compound (a) and/or with itself and which, if its crosslinking groups are epoxy groups, has at least three epoxy groups. A photopolymerizable copying material is also disclosed having a flexible transparent temporary support and a transferable thermoplastic photopolymerizable layer comprising the foregoing radiation-polymerizable mixture. The photopolymerizable layer, after photocrosslinking, can be additionally cured by thermal crosslinking and is therefore suitable for the manufacture of solder resists and high performance printing plates.
