Abstract
The synthesis of some ydroxy-14H-naphtho[2,3-a]phenothiazine-8,13-dion es containing electron donor and acceptor substituents in the un-hydro xylated anthraquinone ring affords colorants of near-infrared absorbin g potential. The relative influence of electron donor and acceptor sub stituents on the absorption maxima of the dyes is reviewed.
