Description

Dispersed yellow 42 (DY42) is a functional group that absorbs ultraviolet radiation and has a high kinetic energy. DY42 can be used as a photoinitiator for polymerization reactions. A study found that DY42 was toxic to rats at doses of 1,000 mg/kg body weight. Polymeric photoinitiators with molecular weights greater than 100,000 are more effective than those with molecular weights less than 100,000. When DY42 is combined with fatty acids or fatty acid esters, it is able to initiate the polymerization reaction in the presence of radiation. The particles produced by polymerization have diameters of 20-30 nm and are spherical in shape.
