Abstract: Radiation-curable urethane prepolymers are made from a mixture in which the isocyanate component contains two different trifunctional isocyanates or one tri- and one di-functional isocyanate, or the unsaturated polyol component contains at least two different unsaturated compounds with reactive hydroxyl groups and possibly other hydroxy compounds. A process for the production of radiation-curable, urethane group-containing prepolymers (PU) comprises reacting an isocyanate component (A) containing trifunctional isocyanate(s) (A1) and optionally difunctional isocyanate(s) (A2) with a polyol component (B) containing unsaturated compound(s) with at least one reactive hydroxyl group (B1) and optionally other OH group-containing compounds (B2), in which either (A) contains two different compounds (A1) or one (A1) and one (A2), or component (B) contains at least two different compounds (B1). Independent claims are also included for the following: (1) radiation-curable urethane prepolymers obtained by this process; (2) radiation-curable preparations containing prepolymers (PU) as above and possibly conventional additives etc.; (3) a process for coating substrates by applying PU or preparations containing PU to the substrate, removing any solvent; and hardening with UV or electron beam radiation; (4) coated substrates obtained by this process.

Abstract: A process for producing coatings of the moulded articles by radiation hardening is characterised in that radiation-hardenable materials, which contain a quantity equivalent to 1-100 wt.% (of the total quantity of cationically and optionally radically polymerisable compounds) of alpha -substituted vinyl ethers with at least one vinyl ether group of formula (I) in which R stands for a C1-C10 alkyl group or a C5-C10 aryl group or C5-C10 cycloalkyl group, are irradiated with high-energy light.

Abstract: The invention relates to positive-working, radiation-sensitive mixtures essentially comprising (a1) an organic binder containing acid-labile groups which is insoluble in water, but becomes soluble in aqueous alkaline solutions on treatment with acid, or (a2.1) a polymeric binder which is insoluble in water, but soluble in aqueous alkaline solutions and (a2.2) an organic compound whose solubility in an aqueous alkaline developer is increased by treatment with acid, and (b) an organic compound which produces an acid on exposure to actinic radiation and which additionally contain (c) a strongly basic, organic compound containing hydroxyl, alkoxy or phenoxy anions. These mixtures are suitable for the production of relief structures of improved contrast.

Abstract: The invention relates to a radiation-sensitive mixture and to a process for the formation of relief patterns. The radiation-sensitive mixture contains (a) a polymeric binder which is insoluble in water and soluble in aqueous-alkaline solutions, and (b) an organic compound whose solubility in an aqueous-alkaline developer is increased by the action of acid and which contains at least one grouping cleavable by acid and additionally one grouping which forms a strong acid under the action of radiation, the polymeric binder (a) containing 5 to 35 mol% of copolymerised or co-condensed monomer units having acid-sensitive groupings, or the acid-sensitive groupings having been introduced by a polymer-analogous reaction. It is suitable for the formation of relief patterns.
