A process for printing flat substrates, in which the said substrate is printed with an ink composition including (a) a basic dye together with (b) an aliphatic carboxylic acid having at least four carbon atoms, (d) a binder resin, and water, yields water-resistant prints having a high depth of shade and high chroma.

Process for printing an aqueous ink composition

Mixtures of metallocenyl phthalocyanines obtainable by reacting a mixture A comprising two phthalocyanines: with a metallocene derivative in the presence of a catalyst, and also oligomeric metallocenyl phthalocyanines, processes for preparing them, their use for, inter alia, optical recording and optical recording media.
