ABSTRACT:
A three-dimensional object formed from a photohardenable composition containing deflecting matter of core-shell polymers. A preferred material for the polymeric core is crosslinked to an extent to be nonswellable and insoluble in solvent for noncrosslinked polymer material while the shell polymer has no pendant acid groups.
