A composition, for producing dispersions, thermoplastic masses and/or color filters, comprising (a) a colorant of formula (1) wherein 20-100 mol % Rare Br and 80-100 mol % Rare 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 colorant (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 colorant 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 colorant substituted by at least one chain containing a plurality of nitrogen atoms (cf. formula (V)). 

Red colour filter composition

The present invention relates to polymers comprising a repeating unit of the formula (I) their use in electronic devices. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high temperature stability of the emission color are observed, if the polymers according to the invention are used in polymer light emitting diodes (PLEDs).
