Date May 1, 1997The invention concerns a process for producing multi-colored plastics, in which slush material is introduced into a mold which can be heated and rotated and has a molding surface. The colorant material comprises a plurality of coloring elements consisting of a colorant content and a transparent plastics cover surrounding the latter or a plastics matrix holding the colorant content together. The colorant content is left in the plastics casing or matrix during sintering and gelling.
