摘要

Liq. photopolymerisable mixt. for printing plate mfr. contains methyl methacrylate (I), benzoin (IIA) or its ether (IIB) and a photopolymerisable component (III), comprising an oligocarbonate methacrylate (IIIA), opt. mixed with an oligoester acrylate (IIB) or oligoester maleate (IIIC) in 1:1 wt. ratio. It contains 5-10 (wt.)% (I), 0.5-1.0% (II), rest (III). Mixt. has high speed and gives printing plates with high physical and mechanical properties.
