  • Patent number: 7955772
    Abstract: The invention relates to a dry toner, containing a platelet-type metal effect pigment or a plurality of platelet-type metal effect pigments and at least one resinous constituent, wherein the metal effect pigment or the metal effect pigments is/are additionally provided with a coating preferably suitable for improving the mechanical stability, and that this coating is additionally modified with at least one organic layer, which organic layer is selected from the group consisting of organofunctional silanes, organofunctional titanates, organofunctional zirconates, phosphonic acids, and phosphonates. The invention further relates to processes for the production of the dry toner and to the use thereof. Furthermore, the invention relates to a toner cartridge and to printed products.

  • Patent number: 7651562
    Abstract: In a metal pigment for a cosmetic preparation, such as lipstick, nail polish, eye shadow, hair colorant, liquid mascara, powder, eyeliner, rouge, skin/hair care products, perfume, eau de toilette, lotions or the like, provision is made for a metallic substrate to have a substrate-enclosing layer produced by the sol-gel process, which provides a barrier effect against sweat and saliva and prevents direct contact between skin and metallic substrate.

  • Publication number: 20070172438
    Abstract: The invention relates to a cosmetic preparation containing a metallic effect pigment which consists of a metal substrate having a layer enclosing the substrate. Said layer is produced in a sol/gel method, has a barrier effect against sweat and saliva and prevents a direct contact between skin and metallic substrate, the metallic pigment being hydrophilic. The inventive preparation can be in the form of a cream, a lotion, an eye shadow, a nail varnish, a lipstick, a mascara, a gel, a make-up formulation or a self-tanning cream or lotion.
