Beschreibung
Zusammenfassung:	The present invention relates to a resin composition that comprises an acetoacetate ester compound with at least two acetoacetate ester functional groups, an acrylate compound with at least two acrylate functional groups, and a tertiary amine curing catalyst. This resin composition acts as an isocyanate-free binder that is less toxic to the environment. The invention further discloses a method for preparation fiber reinforced parts comprising fibers and said resin composition as well as a method for the preparation of foundry molds for the casting industry, which is based on said binder.
