  • Patent number: 8747003
    Abstract: A pencil that includes a polymer-bonded lead, a polymerbonded wood substitute material that includes an organic filler and covers or surrounds the lead along its length, and an adhesion promoter layer disposed between the lead and the wood substitute material. The lead and the wood substitute material each have a polymer. The polymer in the lead being incompatible with the polymer in the wood substitute material so that the polymer of the lead and the polymer of the wood substitute material do not create any connection with one another. The adhesion promoter layer is connected to the polymer in the lead and to the polymer in the wood substitute material so that the adhesion promoter layer forms a connection with the polymer in the lead and with the polymer of the substitute material. The organic filler is formed by particles having a maximum particle size of 250 ?m.

  • Publication number: 20110129284
    Abstract: The invention relates to a writing, drawing, decorating or cosmetic pencil comprising a colour-delivering, polymer-bonded lead and a polymer-bonded wood substitute material, the wood substitute material at least partly covering or surrounding the lead along its length, there being disposed, between the lead and the wood substitute material, at least one adhesion promoter layer, the lead and the wood substitute material each comprising at least one polymer, the at least one polymer in the lead being incompatible with the at least one further polymer in the wood substitute material, and the at least one adhesion promoter layer coupling on the one hand to the at least one polymer in the lead and on the other hand to the at least one further polymer in the wood substitute material.
