Abstract
Abstract Dyestuff preparations are described consisting of 5 to 80% of a finely dispersed dispersion dyestuff having a maximum particle size of 10 Mu ; 5 to 200%, relative to the amount of dyestuff, of a low polymeric compound which is soluble in halogenated hydrocarbons, and which contains at least two CO-groups bound to at most two substituted N-atoms, preferably of a polyurea, polyamide or polyvinylpyrrolidone type, and 20 to 95% relative to the dyestuff preparation, of an inert, non-volatile, organic compound, soluble in halogenated hydrocarbons and having a boiling point of above 200*C, the said organic compound containing, in addition to carbon and hydrogen, at most halogen atoms, or oxygen bound solely to carbon atoms, and having a molecular weight of 100 to 10,000, especially paraffin oil or hard paraffin. The said preparations, liquid or solid, are especially useful for the manufacture of organic dye liquors preferably from perchloroethylene which can be used for the dyeing of organic textile materials consisting of polyester, polyamide or polyacrylonitrile.
