The present invention relates to unsaturated carboxylic acid ester obtained from or through the use of a source material defined below in formula (I):()&#x2003;&#x2003;(I)wherein the figures set in parentheses indicate the molar proportion of source material A to the sum of source materials B and C, andwherein the following meanings apply:A: unsaturated dicarboxylic acid,B: a hard diol segment,C: a soft diol segment selected from among compounds having a continuous chain between two hydroxyl groups, which have a length of 5 to 30 atoms, wherein the molar ratio of B:C is between 5:95 and 95:5. Furthermore, it relates to unsaturated polyester resin comprising said unsaturated carboxylic acid ester as defined above and a reactive diluents as well as molded articles, coatings, and surface textiles coated, saturated, laminated, and impregnated from or with a thermoset, which was obtained by hardening said unsaturated polyester resin.
