Abstract
Metal-free compounds and 1:1 and 1:2 metal complexes of the formula ##STR1## or a 1:2 metal complex of a metal-free compound of said formula and a metallizable azo compound not of said formula, wherein PA0 each K is independently a coupling component radical of the pyrazolone-5, 5-aminopyrazole, pyridone, 2,6-diaminopyridine, .beta.-naphthol, acetic acid ester, acetic acid amide or N-substituted N,N-disubstituted aniline series, PA0 each K.sub.1 is independently ##STR2## wherein R.sub.3 is hydrogen, C.sub.1-4 alkyl, phenyl or benzyl, PA1 R.sub.4 is C.sub.1-4 alkyl, (C.sub.1-4 alkoxy)-carbonyl or --CO--N(R.sub.8).sub.2, wherein each R.sub.8 is independently hydrogen or C.sub.1-4 alkyl, PA1 R.sub.5 is amino or hydroxy, PA1 R.sub.5a is hydroxy, PA1 T is hydrogen, cyano, ##STR3## or (C.sub.1-4 alkyl)carbonyl, wherein R.sub.7, R.sub.10, R.sub.12, Z.sub.a and A.crclbar. are as defined in the specification, PA0 each R.sub.1 is independently hydrogen, halo, hydroxy, C.sub.1-4 alkoxy or C.sub.1-4 alkyl, or PA0 R.sub.1 and R.sub.5, located on rings attached to the same azo radical, are --O--Me--NH or --O--Me--O--, wherein Me is a 1:1 or 1:2 metal complex-forming metal ion, or PA0 R.sub.1 and…
