Pigments, special effect fluorescent

Fluorescent and afterglow products are used to attain special effects in cinema films, on the stage, and in works of art. These effect pigments are physiologically harmless phosphors, mainly based on zinc sulfides. 

Photoinitiators. Derivatives of benzoin and benzil are added in amounts of 1-3% as photoinitiators in UV-curing systems. These have differing effectiveness in the UP systems [2.99], Special initiators are available for pigmented systems. The UV light splits them into radicals which in turn initiate polymerisation. The UV radiation is generated using superactinic fluorescent lamps and/or high-pressure mercury vapour lamps [2.109].
