    Abstract: : New valuable, water-insoluble mixed diaminophenylenedisazomethlne-naphthalene metal-complex compounds had been found consisting of two or more metal-complex dlsazomethine compounds of different constitution or different metal complexes which are prepared according to this invention by reacting one or several o-phenylene diamines with one or several hydroxy-naphthaldehydes at which process metallization is carried out by addition of one or several metal-yielding agents of one or several different metals before, during or after the conden sation reaction of the amino and aldehyde compounds. The new mixed metal-complex compounds are suitable as colorants, especially as pigments for the coloring of printing pastes, printing inks, high-molecular plastic masses, lacquers, paints and spinning masses which colored materials possess very good fastness properties to, for example, light, to weather, to solvents or to migration,and the colorants themselves possess an excellent fastness to heat and have a high tinctorial strength, a good transparency, a good dispersability and, in general, pure shades.
