Beschreibung
Zusammenfassung:	The present invention relates to a color converter comprising a polymeric matrix mate- rial and at least one organic fluorescent colorant selected from a compound of formulae l.a, l.b, l.c or mixturesthereof R1, R2, R3, R5, R6, R7 are hydrogen, C1-C20-alkyl or C6-C14-aryl-C1-C10-alkylene, wherein the aryl moiety is unsubstituted or substituted by k substituents R9; R4a, R4b are fluorine, chlorine, cyano or OR10, R8a, R8b are C1-C20-alkyl; R8C is C1-C20-alkyl, C6-C10-aryl or C6-C10-aryl-C1-C10-alkylene, wherein the aryl moieties in two aforementioned radicals are unsubstituted or substituted by k substituents R9; k, R9 and R10 are as defined in the claims and in the description. The invention also describes the use of color converters; a backlight unit for liquid crystal displays; a liquidcrystal display device and a self-emissive display device comprising this color converter and an ink formulation comprising a compound of formulae l.a, l.b or l.c and the use thereof. 本发明涉及一种包含聚合物基质材料和至少一种有机荧光着色剂的色彩转换器，该至少一种有
