Abstract

Improvements in the photopolymerization of compounds and mixtures of polymerizable compounds, characterized in that said photopolymerization is carried out in the presence of photoinitiators consisting of derivatives of 4,5-diphenyl-5-keto-4-dicloalkoxy-valeric acids, or - 2-methylvalerics, and their salts, of general formula: ** (See formula) ** where R1 represents hydrogen, lower alkyl with up to 4 carbon atoms, lower cycloalkyl with up to 6 carbon atoms or phenyl, R2 means hydrogen or methyl, X means a metallic, mono- or divalent cation, or an ammonium cation and n represents 1 or 2.
