Solid pigment preparations containing as pigment at least one inclusion compound, intercalation compound or solid solution of a metal compound from an azo compound which corresponds in the form of its tautomeric structures to the formula (I) DOLLAR F1 wherein the rings denoted by DOLLAR AX and Y each have one or two substituents from the series = O, = S, = NR¶7¶, -NR¶6¶H¶7¶, -OR¶6¶, -SR¶6¶, -COOR¶6¶, -CN, -CONR¶6 ¶R¶7¶, -SO¶2¶R¶8¶, DOLLAR F2 alkyl, cycloalkyl, aryl, aralkyl, the sum of the endo- and exocyclic double compounds for each of the rings X and Y being three, DOLLAR AR¶ 6¶ represents hydrogen, alkyl, cycloalkyl, aryl or aralkyl and DOLLAR AR¶7¶ represents hydrogen, cyan, alkyl, cycloalkyl, aryl, aralkyl or acyl and DOLLAR AR¶8¶ denotes alkyl, cycloalkyl, aryl or aralkyl, DOLLAR AR ¶1¶, R¶2¶, R¶3¶, R¶4¶ represent hydrogen, alkyl, cycloalkyl, aryl or aralkyl and further, as in formula (I) by d the broken lines are indicated, can form 5- or 6-membered rings to which further rings can be fused, DOLLAR AR¶5¶ -OH, NR¶6¶R¶7¶, means alkyl, cycloalkyl, aryl or aralkyl, the substituents containing CH bonds mentioned for R¶1¶ to R¶8¶ may in turn be substituted and m, n, o, p 1 or in the event that double bonds originate from the ring nitrogen atoms, as in formula (I ) is indicated by the dotted lines, can also mean O, DOLLAR A characterized in that a slurry of the solid pigment preparations with ... |
