    Abstract: A novel sheet-like light-sensitive recording material I with at least one photopolymerisable, relief-forming layer (A) which, relative to (A), contains a1) 20 to 99.499 % by weight of at least one polymeric binder from the group comprising random ethylene/propylene/alkadiene terpolymers of an ethylene content of from 40 to 80 % by weight and a double bond content of 2 to 20 olefinic double bonds per 1000 carbon atoms, a2) 0.001 to 10 % by weight of at least one photopolymerisation initiator, a3) 0.5 to 50 % by weight of at least one monomer which is compatible with the binder (a1) and contains at least one photopolymerisable olefinic double bond, and a4) 0 to 40 % by weight of at least one auxiliary, by means of which the property pattern is varied, and the production of novel relief plates, relief printing plates and photoresists from these novel recording materials I and novel flexographic printing plates which have been produced from the recording materials I.

    Abstract: Mixtures crosslinkable by photopolymerization and based on binders, photopolymerizable monomers compatible therewith and photoinitiators, contain as binders copolymers prepared from (a1) from 30 to 70% by weight of ethylene, (a2) from 5 to 40% by weight of (meth)acrylic acid and (a3) from 5 to 50% by weight of one or more vinyl ester, vinyl ether, (meth)acrylic acid ester and/or (meth)acrylamide.

    Abstract: Non-tacky, smooth, structureless surfaces of photopolymer relief printing plates for flexographic printing, whose relief layers are prepared in a conventional manner by exposing the photopolymerizable relief-forming layers of flexographic printing plates imagewise to actinic light and washing out the unpolymerized, unexposed areas with a suitable solvent, are produced by a process in which the flexographic printing plates are after-treated with a liquid medium which contains elemental bromine or is capable of forming elemental bromine, and then washed with a neutralization bath, one or more paraffinsulfonates, fatty alcohol ethersulfates or alkyl phosphates or a cationic or anionic surfactant possessing one or more perfluorinated carbon chains being employed in the bromine-containing, liquid medium. The relief printing plates obtained according to the invention are used for flexographic printing.
