摘要： The present disclosure is directed to marking compositions that are derived from environmentally friendly, biodegradable, and sustainable resources. Such compositions may be formulated in to writing and/or drawing instruments such as crayons. In various embodiments, the marking compositions include one or more of a structural component, a stiffening and/or laydown component, and a colorant. For instance, the structural component may be an ester wax composed of a diol and diacid, such as where the diols and diacids contain about 2 to about 14 carbon atoms each, such as where the structural component is present in an amount of from about 10% by weight to about 90% by weight, such as about 20% to about 80%, including about 60% of the composition. Additionally, the stiffening and/or lay down component may be a bifunctional fatty acid, such as stearic acid, which may be included in the composition, such as a stiffening agent as well as to enhance smoothness of laydown. A typically useful amount that may be used ranges from about 20% or less to about 80% or more, such as about 40% to 60% or more by weight of the composition. Further, in various embodiments, a naturally occurring, organic colorant may be provided as part of the marking composition.

摘要： A polyester resin composition contains a polyester resin A containing 70 to 100 mass % of a polybutylene terephthalate resin and 0 to 30 mass % of a polyethylene terephthalate resin. The polyester resin composition further contains a metal organic acid salt B, which is either or both of an alkali metal organic acid salt and an alkaline earth metal organic acid salt, and a predetermined amount of a styrenic resin C. The polyester resin composition contains a predetermined amount of either or both of an alkali metal atom and an alkaline earth metal atom relative to 100 parts by mass of the polyester resin A. In the polyester resin composition, the amount of linear oligomers of polybutylene terephthalate or the amount of the linear oligomers of polybutylene terephthalate and linear oligomers of polyethylene terephthalate is less than or equal to 1000 mg/kg.
