  • Plastic Article Comprising Oriented Effect Magnetizable Pigments
    Publication number: 20070182069
    Abstract: Pigments having magnetic properties are manipulated using magnetic fields to produce color patterns. The color patterns may be created in a medium such as a molten plastic or a plastic solution. Once disposed in the flowable medium, the pigments migrate by the influence of magnets after which the pigments remain static due to the drying and/or hardening of the medium. A molded plastic article comprising oriented effect magnetizable pigments is provided. The article may be used to contain cosmetics, personal care products, or foods.

  • Masterbatch precursor
    Publication number: 20050113487
    Abstract: The present invention provides a substantially spherical composition comprising about 60 to 80 percent by weight peariescent pigment, 14 to about 38 percent by weight wax, and about 2 percent to 6 percent surfactant. This composition is particularly useful for extrusion into any polymer used for masterbatching. The masterbatch is then typically blow or injection molded or extruded into a finished part.
