Abstract

Coloured polymeric materials are prepared by (a) forming a mixture of a polymer diluted with a liquid carrier, this mixture preferably being a solution of an organic polymer in 1 or more solvents, (b) shaping the mixture if wished and (c) coagulating the polymer in a coloured form of an agent which does not dissolve the polymer, which is at least partly miscible with the liquid carrier or organic solvent and which contains a dye which is in solution during at least a part of the coagulation, preferably in solution in the non-solvent. The dye is taken up by the polymer during coagulation. The process is simple and cheap. Small quantities of coloured polymer can be prepared economically. Deep shades can be obtained.
