ABSTRACT:
A process for making three dimensional models is disclosed which is characterized in that a photohardenable composition is used which comprises a free radical addition polymerizable or crosslinkable compound and an ionic dye-counter ion compound, said compound being capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of said compound.
