Photoinitiator 784 is an extremely reactive, orange colored solid photoinitiator for radical olymerisation of unsaturated resins upon exposure to visible light (daylight) or UV light. It has a wide absorption in UV spectrum with the typical absorptions at 390 & 460 nm and the absorption extends to 500 nm. It is especially suited for the curing of photopolymers for imaging or information storage applications. It may be used in UV curable formulations for clear and for pigmented coatings on wood, metal, plastic, paper and optical fibers as well as for printing inks.

Its unique absorbance properties together with its outstanding reactivity make it especially suited for use in photopolymers, e.g. resists, printing plates and other information storage devices such as optical layers, holograms, laser direct imaging, stereolithography. Curing can be performed either using UV light, visible light (blue-green part of the spectrum) or even light from suitable laser devices, e.g. Ar-Laser (488nm) or FD-Nd/YAG-Laser (532nm). Best performance is obtained if oxygen is excluded from the resin system during curing.
