RADIATION CURABLE RESIN COMPOSITION AND RAPID THREE-DIMENSIONAL IMAGING PROCESS USING THE SAME

摘要

The invention relates to a liquid radiation curable resin capable of curing into a solid upon irradiation comprising: (A) from about 0 to about 12 wt% of a cycloaliphatic epoxide having a linking ester group; (B) from about 30 to about 65 wt% of one or more epoxy functional components other than A; (C) from about 10 to about 30 wt% of one or more oxetanes; (D) from,about 1 to about 10 wt% of one or more polyols; (E) from about 2 to about 20 wt% of one or more radically curable (meth) acrylate components; (F) from about 2 to about 12 wt% of one or more impact modifiers; (G) from about 0.1 to about 8 wt% of one or more free radical photoinitiators; and (H) from about 0.1 to about 8 wt% of one or more cationic photoinitiators; wherein the liquid radiation curable resin has a viscosity at 30 °C of from about 600 cps to about 1300 cps.
