PHOTOCURABLE COMPOSITIONS CONTAINING REACTIVE PARTICLES

摘要

A photocurable composition, including (a) a cationically curable monomer; (b) a radically curable monomer; (c) reactive particles comprising a crosslinked polysiloxane core and a shell of reactive groups on an outer surface of the core, wherein the reactive groups comprise epoxy groups, ethylenically unsaturated groups, or hydroxy groups; (d) a radical photoinitiator; and (e) a cationic photoinitiator. A method of making a 3-D object from such a composition. A 3-D object made by the method.
