| 摘要 |
A radiation-polymerizable mixture comprising a compound having at least two terminal ethylenically unsaturated groups which can form a crosslinked polymer by means of free-radical initiated addition polymerization, a polymeric binder, a radiation activatable polymerization initiator, and a compound having two epoxy groups in the molecule and a molecular weight of not more than 1,500; and a photopolymerizable copying material having a flexible transparent temporary support and a transferrable thermoplastic photopolymerizable layer comprising the above-described radiation-polymerizable mixture. |
