- (a) at least one compound of the formulae ##STR11## in which A and B are independently of each other one of the groups of the formulae ##STR12## in which R.sub.1 and R.sub.2 are independently of each other hydrogen, halogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -alkoxy, --SR.sub.3, --N(R.sub.3).sub.2 --CF.sub.3, --CN or a group of the formulae ##STR13## R.sub.3 is C.sub.1 -C.sub.5 -alkyl and R.sub.4 and R.sub.5 are independently of each other hydrogen, halogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -alkoxy, --SR.sub.3 or --CN, and
- (b) at least one linear quinacridone compound of the formulae ##STR14## in which W, X, Y and Z are independently of one another halogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -alkoxy and i, k, m and n is zero, 1 or 2, the X-ray diffraction diagrams of the solid solutions differing from the sum of the X-ray diffraction diagrams of the individual components.
- 2. A solid solution according to claim 1, which contains at least one compound of the formulae I or II with the meaning indicated in claim 1 and a quinacridone compound of the formula III in which W is chlorine or methyl and i is zero or 1.
- 3. A solid solution according to claim 1, which contains at least one compound of the formulae I or II with the meaning indicated in claim 1, a quinacridone compound of the formula V in which m is zero and a quinacridone compound of the formula IV in which k is zero.
- 4. A solid solution according to claim 1, which contains at least one compound of the formulae I or II with the meaning indicated in claim 1, a quinacridone copound of the formula V in which m is zero and a quinacridone compound of the formula III in which i is zero.
- 5. A solid solution as claimed in claim 1, which contains at least one compound of the formulae I or II with the meaning indicated in claim 1 and one each of a quinacridone compound of the formulae III, IV and V in which i, k and m are zero.
- 6. A solid solution according to claim 1, which contains a compound of the formula I and at least one compound of the formulae III, IV, V or VI, the compounds of the formulae I, III, IV, V and VI having the meaning indicated in claim 1.
- 7. A solid solution according to claim 6, which contains a compound of the formula I in which A is a group of the formulae ##STR15## in which R.sub.1 is hydrogen, chlorine, bromine, cyano, methyl, ethyl, tert.-butyl or phenyl and R.sub.2 is hydrogen, chlorine, methyl or cyano.
