The new metal azo pigments comprising the adduct ofn a) at least two metal azo compounds of the formula (I) or their tautomeric forms nn n n n n n n n n n n n in which the substituents have the definition indicated in the description, n and n n n b) at least one compound of the formula (II) n n n n n n n n n n n n n n in which n R 6 has the definition indicated in the description, n n n are characterized in that in the X-ray diffractogram with a lattice constant of d=10.3 (±0.2) Å the metal azo pigment has a signal S 1 with an intensity I 1 and in the lattice constant range from d=16.05 Å to d=11.78 Å has no signal S 2 whose intensity I 2 in relation to the intensity I 1 of signal S 1 , expressed as ratio I 2 /I 1 of the background-corrected intensities, exceeds a value of 0.02, n and are outstandingly suitable for producing pigment preparations and especially for producing color filters. |
