A photosensitive composition comprising: (a) a compound of the formula [Figure] [Figure] [Figure] (b) an ethylenically unsaturated compound capable of free radical initiated addition polymerization; (c) a polymeric binder; and (d) a free radical generating system activatable by actinic radiation which comprises a hexaarylbiimidazole and a chain transfer agent. A single step process for forming a light-stable hologram using this photosensitive composition is also disclosed.
