Zusammenfassung:	The invention relates to an unsaturated polyester resin composition comprising: -a (meth)acrylate compound; and, -a polyester formed from at least: -reagent a) comprising itaconic acid and/or itaconic anhydride; -reagent b) comprising maleic acid, maleic anhydride, and/or fumaric acid; -reagent c) comprising dicyclopentadiene (DCPD); and, -reagent d) comprising at least one di- or poly-functional alcohol, preferably at least one diol; wherein the combined weight of reagent a) (i.e. the combined weight of itaconic acid and/or itaconic anhydride) is at least 10 wt. %, preferably at least 20 wt. %, of the total weight of di-acids and anhydrides used in the unsaturated polyester resin composition. The invention further relates to use of said unsaturated polyester resin for structural parts and for gel-coats. The invention also provides methods for preparing said unsaturated polyester resin composition.
