RADIATION CURABLE COMPOSITIONS USEFUL IN SOLID FREEFORM FABRICATION SYSTEMS

摘要

There are provided liquid radiation-curable compositions useful for the production of three-dimensional solid articles in solid freeform fabrication systems. The compositions include a cationically polymerizing alicyclic epoxide having at least two epoxy groups, at least one cationic photoinitiator; at least one free radical photoinitiator; and at least one dendritic polymer having either at least six hydroxyl functional groups or at least six (meth)acrylate functional groups.
