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&#xb0; C. of from about 600 cps to about 1300 cps.

Radiation curable resin composition and rapid three-dimensional imaging process using the same

The invention relates to radiation curable compositions comprising a liquid 0/s(acyl)phosphine photo initiators of formula (&#xcf;): wherein each of Ar, Arand Aris independently a substituted or unsubstituted aryl group. The invention also relates to stabilized forms of liquid bis(acyl)phosphines of formula (I) and radiation curable composition comprising said stabilized photoinitiators. The radiation curable compositions are selected from the group consisting of an optical fiber coating composition and a coating composition capable of radiation cure on concrete and a coating composition capable of radiation cure on metal.
