WebIntroduction. Photoinitiators are compounds added to a formulation to convert absorbed light energy, ultraviolet or visible light, into chemical energy in the form of initiating species, typically free radicals. Traditionally these molecules are engineered for non-polar environments with hydrophobic moieties rendering them water-insoluble. WebPhotoinitiators for white coatings, usually pigmented with TiO 2, require strong absorption in the relatively narrow spectral region of 360–400 nm, below which TiO 2 absorbs strongly and above which the photoinitiator is colored (owing to selective absorption of visible light). Thioxanthones (TX) satisfy this criterion. Combinations of thioxanthones and PI 1 …
