Abstract: Radiation-curable urethane acrylate compounds containing amine and urea groups and based on diisocyanates or polyisocyanates, hydroxyl compounds and amines, characterised by a content of secondary or tertiary amino groups which are bonded to isocyanate via hydroxyl groups and are obtainable by the addition reaction of primary or secondary amines with hydroxyacrylates.

Abstract: The invention relates to novel reaction products containing urea and carboxyl groups and obtained by reacting i) a diisocyanate or polyisocyanate with ii) at least one amino compound and iii) at least one acid anhydride of an at least dibasic carboxylic acid, and optionally iv) a hydroxyl- or amino-containing compound which is different from component ii), where the total number of NCO and anhydride groups in i) and iii) is less than or equal to the number of groups reactive therewith in ii) and iv). This reaction product is suitable for the preparation of radiation-sensitive compositions, in particular compositions whose solubility in water or aqueous-alkaline solution is increased by irradiation.

Abstract: A photosensitive recording element which is suitable for the production of printing plates or resist images possesses a photopolymerizable recording layer which is applied to a dimensionally stable base, can be developed in an aqueous alkaline medium and contains, as a polymeric binder, one or more film-forming copolymers which are insoluble in water but soluble or dispersible in aqueous alkaline solutions and consist of from 10 to 50% by weight of one or more N-vinylamides, preferably N-vinylcaprolactam and/or N-vinylpyrrolidone, from 5 to 30% by weight of acrylic acid and/or methacrylic acid, from 30 to 80% by weight of one or more comonomers from the group consisting of the vinyl aromatics and (meth)acrylates of monoalkanols and from 0.2 to 5% by weight of an olefinically unsaturated compound which contains basic nitrogen atoms and has a pKa>4.
