The present invention relates epoxy(meth)acrylates which are substantially free from epoxide groups and are the reaction products of organic compounds containing epoxide groups and having a number average molecular weight (Mn) of 130 to 1000 with I) compounds containing carboxyl and ester groups at an equivalent ratio of carboxyl groups to epoxide groups of 0.7:1.0 to 1.0:1.0, wherein compounds I) are reaction products of A) organic dicarboxylic acids or dicarboxylic acid anhydrides having a molecular weight of 98 to 164 with B) reaction products containing alcoholic hydroxyl groups and prepared at a COOH/OH equivalent ratio of 0.6 to 0.95 from a) (meth)acrylic acid and b) tri- or tetrahydric ether alcohols having a molecular weight of 180 to 1000, which contain at least two ethylene oxide units -CH2-CH2-O- as part of one or more ether structures and which contain up to 20 mole %, based on the total moles of alkylene oxide units, of propylene oxide units, -CH2-CH(CH3)-O-, and II) basic nitrogen compounds selected from ammonia and (cyclo)aliphaticprimary and secondary amines at an NH/epoxide equivalent ratio of 0:1.0 to 0.3:1Ø The present invention also relates to a process for preparing these epoxy(meth)-acrylates and to their use in radically hardenable coating, putties or sealing com- positions, or for the production of moldings.
