(57) [Summary] [Structure] Formula (I) In the formula, A represents N or a cyanomethylene group, and B is a formula C A novel thiazolyl isoindolenine dye, which represents a group of (CN) COOR 5 or NR 6 , and the remaining groups have the meanings stated in the description. The invention also relates to their mixtures, their method of manufacture and their use for dyeing hydrophobic synthetic materials. The dyestuffs according to the invention dye polyester fibers in yellow, fluorescent shades which have a very high light fastness. The dye mixtures show a significantly improved stability of the dyebaths compared to the individual dyes. The thermal stability of the dye dispersion is It is also a significant improvement compared to the corresponding dispersions of the individual dyes. |
