摘要： A process for the manufacture of coloured shaped articles from high polymer synthetic resins, wherein water-insoluble, hydrophobic, high polymer synthetic resins in solid form, especially in the form of granules or powders, in a mixture of hydrophilic and organophilic solvents that are recriprocally soluble in one another only to a limited extent and form a twophase system, are treated with dyestuffs or optical brighteners, the solubility of which in the organophilic portion of the twophase system is greater than in the hydrophilic portion, the solvent is removed, the synthetic resin dried and shaped, optionally with addition of untreated high polymer fully synthetic resin, from the melt or from a solvent.
