New metal complex dyes with N,O-bidentate indoaniline-type ligands, 5-(4'-dialkylaminophenylimino)quinolin-8-ones (3), have been prepared, which have intense absorption bands in the near-i.r. region and were isolated as stable compounds.A film of complex dye which was prepared from 5-(4'-diethylamino-2'-methylphenylimino)quinolin-8-one and Ni(BF4)2aq showed a λmax value of 772 nm and reflected 54.3percent of the incident ligth intensity at 830 nm; these metal complex dyes have potential as a diode-laser optical storage medium.
