Abstract: The invention relates to a wood substitute material for wood-encased pencils, comprising the following ingredients: 15-3.0% by weight of at least one polymeric binder, 50-80% by weight of at least one organic filler, 0-20% by weight of at least one inorganic filler, 0.5-5% by weight of at least one adhesion promoter, 1-30% by weight of at least one wax, 0-10% by weight of at least one colour pigment, and 0-10% by weight of at least one additive, the at least one adhesion promoter forming a chemical bond between the at least one polymeric binder and the at least one organic filler, a ratio of the at least one adhesion promoter and the at least one wax in the range from 1:2 to 1:6 being formed, and the sum of organic and inorganic filler being not more than 80% by weight.

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.

Abstract: The invention relates to a polymer-bonded pencil lead for writing, drawing or painting devices, in particular for lead pencils or colored pencils, comprising a polymer binder, at least one wax and at least one filler, wherein the pencil lead further comprises 0.1 to 5 wt.-% palm oil.
Abstract: An unburnt color lead for writing devices, drawing devices and painting devices, includes at least one coloring material, at least one binder, at least one organic lubricant which is solid at room temperature, and at least one filler material whose particles essentially have a disk-shaped configuration. The color lead contains 20 to 80 weight % of the at least one filler material, and the color lead contains at least 20 weight % hexagonal bornitride as a first filler material.
Abstract: A non-aqueous ink with an extended cap-off time for writing, drawing, painting or marking, or a writing or marking fluid respectively, having organic solvents, binding agents, drying retarders, colorants and if necessary further additives. The ink contains a fatty acid or a fatty acid blend as a drying retarder.
