    摘要: A high speed photopolymerization negative-acting printing plate containing a layer comprising a photo­sensitized polymerization initiator and polymerizable ethylenically unsaturated compound, exhibits higher speed and good shelf life when at least 20% by weight of the total initiator is situated in an oxygen barrier top coat. Addition of p-substituted-N-disubstituted-anilines to the polymerizable layer gives further improvement in stability.
