Abstract
The invention relates to a radiation curable composition comprising from about 50 wt % to about 70 wt % of a cycloaliphatic diepoxide, from about 5 wt % to about 15 wt % of a polyol, from about 5 wt % to about 15 wt % of an oxetane, from about 10 wt % to about 20 wt % of an aromatic diacrylate, a radical photoinitiator and a cationic photoinitiator. The invention further relates to a process for making a three dimensional article from the resin composition of the invention, to the three-dimensional article itself and to the use of the composition of the invention.
