Abstract
Description
本発明は、ガラス板、合成樹脂板、塗装板等の筆記板に筆記するためのマーキングペンに用いるインキに関する。 The present invention relates to an ink used for a marking pen for writing on a writing plate such as a glass plate, a synthetic resin plate, or a painted plate.
特許文献１には、インキ不浸透性の筆記板（例えばガラス板、合成樹脂板、塗装板等）に筆記し、軟質紙や乾布等の消去材での擦過により筆記線を消去可能なマーキングペン用のインキ組成物の開示がある。このような筆記板用のマーキングインキ組成物は、筆記線の視認性の観点から、筆記板面において筆記線が不透明であることが求められる。特許文献１では、筆記線を不透明化する為に酸化チタンを配合して隠蔽性を付与しているが、酸化チタンは比重が高い為、マーキングペンをペン芯上向きで経時保存した場合に、酸化チタンがペン芯内で分離し、筆記線の隠蔽性が低下する不具合が生じる。その為、特許文献１ではポリビニルブチラール等の樹脂を配合する事で酸化チタンの分散を安定化させ、前記課題を解決している。 Patent Document 1 describes a marking pen capable of writing on an ink-impermeable writing plate (for example, a glass plate, a synthetic resin plate, a painted plate, etc.) and erasing the writing line by rubbing with an erasing material such as soft paper or dry cloth. There is a disclosure of ink compositions for. Such a marking ink composition for a writing board is required to have an opaque writing line on the writing board surface from the viewpoint of visibility of the writing line. In Patent Document 1, titanium oxide is blended to make the writing line opaque to impart concealment. However, since titanium oxide has a high specific gravity, it oxidizes when the marking pen is stored with the pen core facing upward over time. Titanium separates in the pen core, causing a problem that the concealment of the writing line is reduced. Therefore, in Patent Document 1, the dispersion of titanium oxide is stabilized by blending a resin such as polyvinyl butyral, and the above-mentioned problems are solved.
しかしながら、特許文献１記載のインキ組成物では、樹脂を配合する事で酸化チタンの分散性は良好となるものの、筆記線の筆記板に対する密着性が強くなる為、筆記線を消去する際に不必要に強い力で消去材を擦りつける必要があり、消去性に問題があった。 However, in the ink composition described in Patent Document 1, although the dispersibility of titanium oxide is improved by blending the resin, the adhesion of the writing line to the writing plate is strengthened, so that it is not possible to erase the writing line. It was necessary to rub the erasing material with a strong force, which caused a problem in erasability.
本発明は、酸化チタンの経時的なペン芯内分離による隠蔽性低下の防止と、筆記線を軽い擦過力で消去する事ができる容易消去性の両立を可能とする筆記板用消去性インキ組成物を提供する。 The present invention has an erasable ink composition for a writing board that enables both prevention of deterioration of concealment due to separation of titanium oxide in the pen core over time and easy erasability that allows the writing line to be erased with a light scraping force. Provide things.
上記の課題を解決するために完成された発明は、水、酸化チタン、消去性付与剤、ポリアミド、脂肪酸アミドを含有する筆記板用消去性インキ組成物である。 The invention completed to solve the above problems is an erasable ink composition for a writing board containing water, titanium oxide, an erasable imparting agent, a polyamide, and a fatty acid amide.

In the present invention, polyamide and fatty acid amide are used as the resin. Polyamide and fatty acid amide prevent deterioration of hiding power due to separation of titanium oxide in the pen core over time, thereby clarifying the writing line on the writing board surface and at the same time, the adhesion of the writing line to the writing board is poor. Since it does not rise as necessary, it is possible to realize easy erasability of erasing the writing line with a light rubbing force. Examples of the polyamide and fatty acid amide used include "Disparon AQH-810 (manufactured by Kusumoto Kasei Co., Ltd.)" in which the above two types of resins are mixed in advance. In addition to Disparon AQH-810, there is no problem even if a commercially available single polyamide and fatty acid amide are mixed and blended.
The blending amounts of the polyamide and the fatty acid amide alone are 0.05 to 0.6% by weight, preferably 0.1 to 0.5% by weight, based on the total amount of the ink.

Table 1 shows the ink formulations of Examples and Comparative Examples.
The examples and comparative examples were tested under the following conditions.
(1) Concealment test: The marking pens filled with the inks of Examples and Comparative Examples were left to stand in an environment of 20 ° C. × 65% for 14 days with the pen core facing upward, and then the writing lines written on the glass plate. The concealment property of was evaluated.
◯: The lining of the glass plate does not show through from above the writing line, and the writing line can be clearly seen.
X: The lining of the glass plate can be seen through from above the writing line.
(2) Erasability test: Writing was performed on a glass plate with a marking pen filled with ink of Examples and Comparative Examples, and after 8 hours had passed, the writing line after rubbing with a sponge having a load of 250 g was evaluated.
◯: The writing line disappears completely within 5 round trips.
X: A part of the writing line remains after 5 round trips.
(3) Ink Dischargeability Test: The density of the writing line after hand-writing 6 m on a glass plate with the pen core upward (60 to 70 °) with the marking pens filled with the inks of Examples and Comparative Examples was evaluated.

表１の比較例１、２は、酸化チタン・消去性付与剤にポリビニルブチラール樹脂、エチルセルロース樹脂をそれぞれ組み合わせた配合である。実施例１〜４は、比較例１、２で配合した樹脂をポリアミドと脂肪酸アミドの混合樹脂に置換えた配合である。比較例１、２は、経時後のペン芯に酸化チタンの分離が生じず、隠蔽性は良好であるが、消去性が著しく悪い。一方、実施例１〜３は、比較例１、２と樹脂総配合量は同一であるが、隠蔽性は良好な状態を維持しつつ、消去性も優れている事がわかる。理由は不明だが、ポリアミド及び脂肪酸アミドと、消去性付与剤（一般的に、筆記線が板面に強固に密着するのを適度に防ぐ性質を有する物質。表１では流動パラフィンと脂肪酸アルキルエステル）を併用すると相乗効果が生じ、消去性が著しく向上するものと考えられる。これにより、酸化チタンの経時的なペン芯内分離による隠蔽性低下の防止と、筆記線を軽い擦過力で消去する事ができる容易消去性の両立が可能となる。
また、比較例３は、実施例１〜４のポリアミドと脂肪酸アミドの配合量をそれぞれ０．７重量％まで増加させた配合である。この場合、インキ粘度が過剰になる為、ペン芯からのインキ吐出し性能が著しく悪くなる。以上の結果よりポリアミドと脂肪酸アミドの配合量はインキ全量に対してそれぞれ０．１〜０．５重量％が好ましいと考えられる。
Comparative Examples 1 and 2 in Table 1 are formulations in which a polyvinyl butyral resin and an ethyl cellulose resin are combined with a titanium oxide / scavenging agent. Examples 1 to 4 are formulations in which the resins compounded in Comparative Examples 1 and 2 are replaced with a mixed resin of polyamide and fatty acid amide. In Comparative Examples 1 and 2, titanium oxide does not separate from the pen core after a lapse of time, and the concealing property is good, but the erasability is remarkably poor. On the other hand, in Examples 1 to 3, the total amount of the resin compounded is the same as that of Comparative Examples 1 and 2, but it can be seen that the hiding property is maintained in a good state and the erasability is also excellent. For unknown reasons, polyamides and fatty acid amides, and scavenging agents (generally, substances that have the property of appropriately preventing the writing line from firmly adhering to the plate surface. Liquid paraffin and fatty acid alkyl esters in Table 1) It is considered that the combined use of the above produces a synergistic effect and significantly improves the erasability. As a result, it is possible to prevent a decrease in concealing property due to the time-dependent separation of titanium oxide in the pen core and to achieve both easy erasing property in which the writing line can be erased with a light scraping force.
Further, Comparative Example 3 is a formulation in which the blending amounts of the polyamide and the fatty acid amide of Examples 1 to 4 are increased to 0.7% by weight, respectively. In this case, since the ink viscosity becomes excessive, the ink ejection performance from the pen core is significantly deteriorated. From the above results, it is considered that the blending amount of the polyamide and the fatty acid amide is preferably 0.1 to 0.5% by weight, respectively, with respect to the total amount of the ink.
