The camphorquinone (CQ)/amine and CQ/diphenyl (2,4,6‐trimethylbenzoyl)‐phosphine oxide (TPO)/amine photoinitiating systems (PISs) are largely used in the area of dental resins, but the role of the light source in connection with the excited state processes has not been deeply investigated so far. Dates: Modify . ValloEffect of different photoinitiator systems on conversion profiles of a model unfilled light-cured resin. Some efficient acylphosphine oxides have been used for many years as photoinitiators of radical polymerization. Grouping and reading-across between these substances could lead to over classification by ECHA.
