Abstract
A photohardenable composition comprising a free radical addition polyermizable or crosslinkable compound and a cationic dye-borate anion complex, said complex being capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization of crosslinking of said compound; and photosensitive materials employing the composition where in one embodiment the composition is microencapsulated.
