Abstract: The invention relates to a reaction product containing urea and urethane groups and carboxyl groups and obtained by reacting …… i) a mono- or polyethylenically unsaturated mono- or polyalcohol with … ii) a diisocyanate or polyisocyanate, … iii) at least one amino compound and … iv) at least one acid anhydride of an at least dibasic carboxylic acid, where the total number of NCO and anhydride groups in ii) and iv) is less than or equal to the number of groups reactive therewith in i) and iii). …… This reaction product is suitable for the production of radiation-sensitive materials, in particular materials whose solubility in water or aqueous-alkaline solutions is increased by irradiation.
