の汚染原因ともなる。The glycol ether ester compound is a release property-imparting additive that facilitates erasing the handwriting of ink, and the conditions of X and R 1 , R 2 and R 3 in the general formulas (1) and (2) are mainly commercial. Although it is a restriction from the viewpoint of physical availability, if the carbon number of R 4 is less than 5 or if n exceeds 10, the ink swells the plastic material and hinders the erasability of the handwriting, which is not preferable. The glycol ether ester compound is 0.5 to 20% by weight, preferably 4 to 15% by weight in the ink composition.
Used in the range of. Inks containing less than 0.5% by weight do not have sufficient erasability of handwriting, and those containing more than 20% by weight tend to deposit supersaturated components, resulting in lack of ink stability and contamination of the writing plate surface.

も良好な筆跡消去性を示す性能を備えている。The writing plate ink of the present invention uses a combination of a pigment selected from organic pigments and fluorescent pigments as a coloring component and titanium dioxide, so that it can be clearly recognized even on a writing plate composed of a transparent material or a darkly colored surface. By the action of the glycol ether ester as an additive that gives a handwriting that can be released and is provided with peelability to the handwriting, it is composed of various surface materials having different erasability of the handwriting due to the addition of titanium dioxide and different chemical properties. All of the writing boards have the ability to show good handwriting erasability.

は不揮発性であり、筆跡が形成されて経時してもその作
用は持続される。The glycol ether ester is dissolved in the organic solvent and stably exists in the ink, and when a handwriting is formed, the resin in the ink is firmly adhered to the plate surface at the interface with the writing plate. That contributes to the erasability of handwriting.
Since the compound has a structure having a hydrophilic portion and a hydrophobic portion in a molecule in a well-balanced manner, it shows an affinity to the writing plate surface regardless of the chemical characteristics of the hydrophilic or hydrophobic surface material,
It is considered to fulfill the above function. Further, the compound itself is non-volatile, and its action is maintained even after the handwriting is formed and the time passes.
