A composition, for producing dispersions, thermoplastic masses and/or colour filters, comprising (a) a colourant of formula (1) wherein 20-100 mol% R1 are Br and 80-100 mol% R3 are H, especially of formula (Ib) and /or (Ic); (b) from 0 to 150 % by weight, based on (a), of C. I. Pigment Red 144, 188, 190, 224, 242 or 2,4,6-trimethylphenylperylene diimide; (c) from 3 to 25 % by weight, based on (a), of a di- or tri-azacyclopentylmethyl-substituted colourant (formulae given); (d) from 0 to 10 % by weight, preferably from 0.01 to 8 % by weight, based on the sum of (a) and (b), of an additionally sulfonated colourant of the same kernels as in (c); and (e) from 0 to 30 % by weight, preferably from 3 to 25 % by weight, especially from 5 to 20 % by weight, based on (a), of a diketopyrrolopyrrole colourant substituted by at least one chain containing a plurality of nitrogen atoms (cf. formula (V)). The compound of formula (Ig), wherein R20 and R22 are, each independently of the other, H, Cl, Br, CN, CF3, R22, OR22, SR22, SOR22, SO2R22, NR23COR22, COOR23, CONR22R23, CONH2, CON(R22)2 or CON(R24), preferably Cl, Br, CN or R22, wherein R22, in each case independently of any other R22, is C1-C5alkyl, C2-C5alkylene, phenyl or 2-naphthyl, preferably methyl or phenyl, R23, in each case independently of any other R23, is H, d-C5alkyl or C2-C5alkylene, preferably H Or CH3, and R24, in each case independently of any other R24, is C4-C8alkylene which is uninterrupted or interrupted one or more times by NR23, NOR23, O, S, SO or by SO2, R24 in N(R24) forming with N a preferably 5- or 6-membered heterocyclic ring, with the proviso that R20 and R21 are not simultaneously Br and H, respectively, and also solid solutions thereof are likewise claimed. Also claimed is the compound of formula (Vb), wherein R27 is Br, Cl, F or methyl, R28 is H, C1-alkyl, or C6-C12alkyl wherein a carbon atom has been replaced by a nitrogen atom, and R29 is C6-C18alkyl wherein 1 or 2 carbon atoms has/have been replaced by nitrogen atom(s).
