If the reactive species in the chemical activation step initiates a radical chain with a chain length CL, then the overall quantum yield based on the ultimate product is X CL, and can be greater than 1. Photons are rather expensive reagents, and are only used when the product is of substantial value or when the overall quantum yield is large. Examples are the use of photoinitiators for the curing of coatings (a radical-polymerization process (Section 7.3.1)), and the transformation of complex molecules as medications. 

Recently, there has been an issue with the detection of 4-methylbenzophe-none (MBP) in breakfast cereal in Europe, leading to publicity concerning the presence of this photoinitiator in the food. Based on the close similarity between MBP and benzophenone, a photoinitiator for inks and coatings that are cured with UV light, the European Food Safety Authority (EFSA) has concluded that short-term consumption of breakfast cereals containing ppm traces of MBP should not pose a risk to most people, but recommended that this substance undergo more detailed evaluation if it will continue to be used in food packaging. ...

Cationic photoinitiators are of basic interest for coating applications, printing plates for silk screen printing inks, photoresists, name plates etc. 

An interesting characteristic of mthenocene is that it is a photoinitiator for the anionic polymerization of ethyl 2-cyanoacrylate. Solutions with millimolar concentrations of the complex in neat cyanoacrylate polymerize to a hard, plastic solid within seconds upon exposure to light. The low concentration of mthenocene required for the polymerization makes it desirable in applications such as coating and adhesives that require solvent-free solutions of monomer. ... 

During the past twenty years, development of compounds that efficiently initiate polymerization on irradiation have made possible the development of several new commercially important technologies based on these photoinitiators [1]. Their use in UV curable coatings is particularly notable. The most useful photoinitiators that have been explored to date are radical photoinitiators. Many applications today use this technology, in spite of important drawbacks [2]. The recent development of diaryliodonium, triarylsulfonium and ferrocenium salts as highly efficient photoinitiators for cationic polymerization has generated a new class of fast polymerizations.

On the other hand, it has been reported that triarylsulfonium salts are very reactive photoinitiators for the ring opening of epoxy monomers 7J. It was also reported (49) that a coating composed of 4% by weight of triphenylsulfonium hexafluorophosphate in 3,4-epoxy cyclohexyl methyl-3,4-epoxy cyclohexane carboxylate cured in 20 seconds exposure.
