Abstract
Dialkoxy-acetyl derivatives of aromatic compounds are photosensitizers for the curing of photopolymerisable systems. They can be synthesized from aromatic acetyl compounds(aryl methyl ketones) by reaction with nitrosyl chloride and the corresponding alkanol. Examples of photopolymerizable systems are coatings or printing inks on the basis of unsaturated polyesters or acrylic compounds.
