Abstract: Prepn. of endless solid, light-sensitive polymeric recording coating (I) on a cylindrical surface for the mfr. of printing moulds comprises applying the recording compsn. forming (I) to the cylindrical surface in a fluid form to produce an endless coating followed by hardening. During hardening, the surface of (I) is rolled to produce a defined surface structure. Also claimed is the prepn. of endless printing moulds in which a cylindrical surface is coated with a fluid, light-sensitive, polymeric recording compsn. to form (I) which is hardened and illuminated with actinic light, and developed by removing the (non) illuminated regions esp. using a developer solvent.

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.
