| 摘要 |
This invention relates to new fluorescent or non-fluorescent dye compounds having a terminal hydroxy, carboxylic acid/ester or amino group and a process for their preparation. The new fluorescent or non-fluorescent dye compounds are useful as colorants for preparing colored synthetic polymer resins with pigmentary properties, for dyeing or printing homo- or mixed synthetic, semi-synthetic or natural polymers or substrates or for preparing inks. The dye compounds provide excellent properties, especially high temperature stability and easy applicability.
