The new metal azo pigments comprising the adduct of
a) at least two metal azo compounds of the formula (I) or their tautomeric forms
in which the substituents have the definition indicated in the description,
and
b) at least one compound of the formula (II)
in which
R6 has the definition indicated in the description,
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 S1 with an intensity I1 and in the lattice constant range from d=16.05 Å to d=11.78 Å has no signal S2 whose intensity I2 in relation to the intensity I1 of signal S1, expressed as ratio I2/I1 of the background-corrected intensities, exceeds a value of 0.02,
and are outstandingly suitable for producing pigment preparations and especially for producing color filters.
