Abstract
Abstract Mixed crystals of at least two different compounds of formula ##STR1## wherein A and B are each independently of the other a cation of formula ##EQU1## or N + H(R 1 )(R 2 )(R 3 ) M is a mono-, di- or trivalent metal cation, n is 1, 2 or 3, R 1 , R 2 and R 3 are each independently of one another hydrogen, C 1 -C 22 alkyl, C 7 -C 24 aralkyl, C 5 -C 6 cycloalkyl or C 6 -C 18 aryl, m is 0 or 1, and R is hydrogen, C 1 -C 4 alkyl or C 1 -C 4 alkoxy, in which compounds of formula I that form the mixed crystals the cations A and B constitute a composite structure ##EQU2## wherein x is a value from 0.2 to 0.8, and the X-ray diffraction pattern of said mixed crystals differs from that of the corresponding compounds in which x is 1 or 0. These mixed crystals can be used as pigments for colouring organic material of high molecular weight and have exceptional properties, especially dispersibility, heat- and lightfastness.

Claim 1
Independent Claim
167 words
Mixed crystals of at least two different compounds of formula ##STR9## wherein A and B are each independently of the other a cation of formula ##EQU10## or N + H(R 1 )(R 2 )(R 3 ) M is an alkali metal cation, an alkaline earth metal cation or a transition metal cation, n is 1, 2 or 3, R 1 , R 2 and R 3 are each independently of one another hydrogen, C 1 -C 22 alkyl, C 7 -C 24 aralkyl, C 5 -C 6 -cycloalkyl or C 6 -C 18 aryl, m is 0 or 1, and R is hydrogen, C 1 -C 4 alkyl or C 1 -C 4 alkoxy, in which compounds of formula I that form the mixed crystals the cartions A and B constitute a composite structure ##EQU11## wherein x is a value from 0.2 to 0.8 and the X-ray diffraction pattern of said mixed crystals differs from that of the corresponding compounds in which x is 1 or 0.
