    Abstract: Light-sensitive registration material comprising… A) a photopolymerisable relief-forming layer which, after imagewise exposure to actinic light, can be developed with a liquid developer,… B) a covering layer which adheres firmly to the photopolymerisable relief-forming layer (A), is soluble or swellable in the liquid developers and is composed of polymers forming rupture-resistant films, and… C) a covering sheet which can readily be peeled off the covering layer (B),… the covering layer (B) containing specific tertiary amines and/or amides and/or specific quaternary ammonium salts of the type according to the claims and defined in greater detail. … A process is also provided for producing photopolymerisable printing plates, relief plates or photoresists using this registration material.

    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: The polymers (I), in form of acids or their salts, comprise A) copolymer of a1) 30-70 pts.wt. ethylene, a2) 5-40 pts.wt. acrylic and/or methacrylic acid, a3) 5-40 pts.wt. one or more vinyl esters, vinyl ethers, esters of (meth)acrylic acid, acrylamide and/or methacrylamide, and B) lateral residues, introduced therein by polymer-analogous reaction, of formula -CH2.CH(X).CH2Y.C(R'):CH2 (where X=OH, amino, or SH; Y=ester, amide, ether, or 1-10C alkylene gp.; R'=H or Me) and opt. C) further lateral residues, introduced by polymer-analogous reaction of formula -CH2.CH(X)R2 (where R2=polar gp., H, or a further gp. X). Pref. A) consists of 40-60 pts.wt. a1), 8-30 pts.wt. a2), and 20-40 pts.wt. a3). (I) contain C) where R=omega-alkyl-poly(ethylene oxide)-alpha-oxyl residue. (I) is a metal, ammonium, or hydrazinium salt, or salt of a polyfunctional amine. a3) is vinyl acetate, vinyl Bu ether, n-Bu, 2-ethylhexyl, or dicylopentadienyl acrylate, and/or omega-methyl-poly(ethylene oxide)-alpha-yl acrylate (II).

    Abstract: Light-sensitive copying material for producing printing plates or resist patterns has a photopolymerisable copying layer on a dimensionally stable substrate, which can be developed with aq. alkali or organic solvent. This contains a polymeric binder, which is soluble or dispersible in aq. alkaline medium or organic solvent, low mol. ethylenically unsatd. photopolymerisable organic cpd(s), photopolymerisation initiator(s), and opt. other additives. The novelty is that the binder consists of film-forming copolymer(s) (I) with multiphase morphology, in which at least one phase has a Tg below room temp. and at least one other phase of Tg above room temp. (I) is produced by free radical copolymerisation of macromer(s) (II) with other olefinically unsatd. copolymerisable organic cpd(s) (III).
