Abstract
Abstract A process for the dyeing of synthetic organic material is described, the said process comprising the discontinuous or continuous dyeing, at temperatures preferably above 120*C, of said material from a dye liquor consisting of 20 to 75 per cent by weight of a water-insoluble, aliphatic or cycloaliphatic hydrocarbon having at least 8 carbon atoms, and 80 to 25 per cent by weight of a polyhalogenated, lower alphatic hydrocarbon boiling between 70* and 180*C, and at least one advantageously finely divided dispersion dyestuff, and optionally further additives; and, optionally, the subsequent rinsing and drying of the dyed synthetic organic material, whereby deeply coloured dyeings are obtained which are even and fast to light, wetprocessing, sublimation and rubbing even on poorly absorbing material.
