Abstract

DEPCT63 This disclosure is aimed at marking constituents derived from environmentally friendly, biodegradable, and sustainable sources. Such elements may be formulated into writing and/or drawing tools, such as colored bars, in various forms. Marked elements include one or more of Structural components, hardeners and/or pastes, and coloring agents. For example, structural components may be ester waxes containing diols and diacids, e.g. Diacids have about 2 to about 14 carbon atoms each, for example, where structural components It exists in amounts from about 10% by weight to about 90% by weight, i.e. about 20% to about 80%, including about 60% of the constituents. In addition, hardening and/or laminating components may be bifunctional fatty acids, such as stearic acid, that may be included in the composition, e.g. hardening agents, also to improve the laminating smoothness. Typical useful amounts that may be consumed range from approximately 20% or less to approximately 80% or more, i.e. approximately 40% to 60% or more by weight of the constituent. In addition, various appearances Organic coloring agents based on Nature may be provided as part of a mark element. -------------------------------------------------- ---------
