A photohardenable composition 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. The use of such compositions in dentistry, for producing holograms, for producing three-dimensional models and for protecting or repairing underwater surfaces, is also described.
