| 摘要 |
A recording material polymerisable by radiation is described, having a flexible transparent temporary base, a transferrable thermoplastic radiation-polymerisable photoresist layer which contains a) a polymeric binder, b) a free radical-polymerisable, ethylenically unsaturated compound having a boiling point above 100 DEG C at normal pressure, c) a compound or a compound combination which is capable of initiating the polymerisation of compound b) under the action of actinic radiation, and d) an aliphatic polyol having 2 to 15 hydroxy groups, and, on the free side of the photoresist layer, a peel-off cover sheet which adheres less strongly to this layer than the temporary base. The photoresist layer is distinguished by improved adhesion in the unexposed state, as compared with copper, and by high flexibility. |
