The invention relates to a resinncomposition comprising (A) an unsaturated polyester,n(B) a monomer that is copolymerizable with thenunsaturated polyester (A), (C) optionally an anti-shrinkncomponent, (D) reinforcing fibres and (E)nfillers, and is characterized in that the unsaturatednpolyester (A) has an acid number of less than 18 mgnKOH/g and is a combination of a standard unsaturatednpolyester (A1) having an acid number of more than 13 mgnof KOH/g and of a modified unsaturated polyester (A2)nhaving an acid number of less than 13 mg of KOH/g, thenacid number being as measured according to ISO 3682. |
