| 摘要 |
The invention relates to novel pasty or solid dye melts which contain, per 1 part of a sparingly water-soluble or water-insoluble dye whose melting point is higher than 150 DEG C., 2 to less than 5 parts of a nonionic surfactant with a melting point of 25 DEG -100 DEG C. and having an HLB value of 13 to 19 or of a cationic surfactant with a melting point of 25 DEG -100 DEG C., or a mixture of said surfactants, to a process for their preparation and to the use of said melts, preferably for dyeing and printing polyester materials, to give level dyeings having a high degree of exhaustion.
