  • Patent number: 7892461
    Abstract: Description of a method for the production of a pigmented thermoplastic material. The method characterizes that during a first step an aqueous suspension presenting a solid matter contents of approximately 10 to 75% by weight, containing at least one flow enhancer in form of dissolved salt and the pigment, is ground under alkaline conditions in a high energy charging mill by means of grinding bodies having a diameter of 0.2 to 2 mm, and the obtained grinding product is transformed during a second step with a thermoplastic material into the pigmented thermoplastic material by means of a flush process performed by a kneader or extruder, at increased temperature and a pH value of initially 7 or less. In addition, the invention concerns a pigmented thermoplastic material produced according to said method, as well as beneficial applications for production of transparent molded bodies, in particular of fibers, foils, injection moldings and extruded parts.
