More Information
Summary:Described are 1,3-diaza-9-thia-anthracene-2,4-diones of the general formula (II) < IMG > (II) wherein R1, R3 and R4 are identical or different and individually each denotes a hydrogen or halogen atom, an alkyl, alkoxy, carboxyl or alkoxy-carbonyl group, R2 denotes an alkoxy, carboxyl or alkoxycarbonyl group, or two of the groups R1, R2, R3, and R4 together form a condensed aromatic radical. These compounds are used as photoinitiators in photopolymerizable recording materials and have an increased sensitively in the spectral range between 425 and 480 nm.
