Abstract

Dithiolene complexes of the formula ##STR1## where Me is nickel, palladium or platinum, and <A is ##STR2## are readily soluble in organic solvents and have a high absorption in the range from 750 to 850 nm and are therefore very useful for optical recording media. The complexes may furthermore be used as antioxidants, stabilizers, corrosion inhibitors or catalysts, or as protective layers for colored photographic layers.
