Abstract
The invention relates to a radiation curable resin composition comprising a cationically polymerizable component, a cationic photoinitiator, a hydroxy component, an impact modifier and wherein the resin composition after full cure has a modulus of >2 GPa; a yield stress <70 MPa; and a Kvalue >1.3 MPa·(m)or an Izod value >0.45 J/cm. The resin composition can preferably be used in the preparation of three dimensional objects.
