Benzophenone is widely employed as a photo initiator in UV-curing applications such as inks, imaging and clear coatings in the printing industry. It acts as a UV blocker to prevent photo-degradation of the packaging polymers or its contents. It protects some products such as perfumes and soaps from ultraviolet light. It serves to manufacturers to package the product in clear glass or plastic.
For a review of the use of benzophenone as a triplet-sensitizer in photochemistry, see: Synthesis, 249 (1981).
