    摘要: The invention seeks to provide a free-flowing formulation of one or more disperse dyes, with which packages can be dyed homogeneously by the HT process without filtering out of the dye, and which is suitable for the thermosol dyeing process. According to the invention such a formulation comprises one or more disperse dyes (a) enclosed in a matrix of one or more polymers (b) which are soluble, or colloidally soluble, both in water and in an organic solvent, in the form of a solid solution in a state of molecular dispersion or of extremely fine subdivision so that in an X-ray spectrum the dye appears amorphous.The formulations may contain additional assistants conventionally present when dyeing hydrophobic fibers. The formulations contain the disperse dye in an extremely fine state of subdivision. Because of the latter, the formulations give level package dyeings, without filtration of the dye, and very level dyeings when used by the thermofixing process.
