Pigment preparations

A pigment preparation comprising:

• i) a metal azo pigment A) containing the components
• a) at least two metal azo compounds of the formula (I) which differ at least in the metal ion Me, or the tautomeric forms thereof,
• in which
• R1 and R2 are each independently OH, NH2 or NHR5,
• R3 and R4 are each independently ═O or ═NR5,
• R5 is hydrogen or alkyl, and
• Me is a metal ion Me1 or Me2,
• wherein
• Me1 is Cu2+ or Ni2+ and Me2 is Zn2+, Al3+2/3, Fe2+, Fe3+2/3, Co2+, Co3+2/3, La3+2/3, Ce3+2/3, Pr3+2/3, Nd2+, Nd3+2/3, Sm2+, Sm3+2/3, Eu2+, Eu3+2/3, Gd3+2/3, Tb3+2/3, Dy3+2/3, Ho3+2/3, Yb2+, Yb3+2/3, Er3+2/3, Tm3+2/3, Mg2+, Ca2+, Sr2+, Mn2+, Y3+2/3, Sc3+2/3, Ti2+, Ti3+2/3, Nb3+2/3, Mo2+, Mo3+2/3, V2+, V3+2/3, Zr2+, Zr3+2/3, Cd2+, Cr3+2/3, Pb2+ or Ba2+,
• with the proviso that the amount of metal ions Me1 in total is 97 to 100 mol % and the amount of metal ions selected from the series Me2 in total is 0 to 3 mol %, based in each case on one mole of all compounds of the formula (I),
• and
• wherein the molar ratio of Cu to Ni metal ions in the sum total of the compounds of the formula (I) is 99.9:0.1 to 0.1:99.9,
• and
• b) at least one compound of the formula (II)
• in which
• R6 is hydrogen or alkyl,
• or a metal azo pigment A) prepared by reacting component a) with component b),
• and
• ii) at least one aliphatic monocarboxylic acid B) having 10 to 22 carbon atoms in an amount of from 70 to 210 g based on 1 mol of all metal azo compounds (I) present in the metal azo pigment A).
