−84369号公報には庶糖エステルが開示されている。(Prior Art) Conventionally, a marking ink composition is known which can be written on a non-absorbing surface and whose handwriting can be easily erased by rubbing. The marking ink composition usually contains a relatively low boiling point organic solvent, a coloring agent, and a coloring agent, so that when it is written on a non-absorbing surface, it rapidly dries to give clear and sharp handwriting.
It is composed of a resin and a release agent. Therefore, when the marking ink composition is used for a writing instrument, if the marking ink composition is left with the cap removed, the organic solvent evaporates from the ink composition at the pen tip portion to deposit a coloring material or resin, and It has the disadvantages of clogging inside and obstructing ink ejection from the pen tip, making the handwriting faint and incapable of writing. Therefore, in order to suppress the evaporation of the solvent from the nib and improve the nib dry resistance, JP-A-58-79067 discloses alkyd amide alcohol and sorbitan fatty acid ester as nib dry resistance improvers. , JP-A-60
No. 84369 discloses saccharose ester.

る。(Function) The decaglycerin stearate partial ester represented by the general formula (1) used in the present invention is colloidally and uniformly dispersed in the ink, and the organic solvent in the ink composition evaporates at the pen tip. Then, it deposits at the same time as the resin and forms a very brittle film on the surface of the pen tip. It is considered that this coating suppresses evaporation of the organic solvent, and since this coating is easily destroyed by normal writing pressure, the nib dry resistance is improved. Moreover, this decaglyceryl stearate partial ester has a larger volume when it is dispersed in a solvent in a colloidal form than the above-mentioned other nib drying resistance improvers, so even a small addition amount is sufficient. It has the property of forming a very brittle film on the surface of the pen tip, and this property seems to be useful for producing the effect.
