Abstract
A radiation curable resin composition suitable for making three dimensional objects comprising at least one epoxy compound, a cationic photoinitiator, wherein the resin composition has a first color or no color before cure and wherein a three dimensional object made from the resin by subjecting the resin to radiation shows a second color which is different from the color of the resin composition before cure.
Claims22
