Abstract

See full text

Relief plates crosslinked by photopolymerization are produced by exposing layers which are crosslinkable by photopolymerization imagewise to actinic light and washing out the noncrosslinked parts of the layers with a developer, by a process in which the developer used contains, as an essential component, a branched or straight-chain, monoolefinically, diolefinically or triolefinically unsaturated acryclic or saturated or monoolefinically, diolefinically or triolefinically unsaturated cyclic aliphatic hydrocarbon, alcohol or ketone of 8 to 15 carbon atoms.
