本発明では、図３に示すように、温度変化による着色濃度の変化をプロットした曲線の形状が、温度を変色温度域より低温側から上昇させていく場合と逆に変色温度域より高温側から下降させていく場合とで異なる経路を辿って変色し、完全発色温度（ｔ１）以下の低温域での発色状態、または完全消色温度（ｔ４）以上の高温域での消色状態が、特定温度域〔ｔ２〜ｔ３の間の温度域（実質的二相保持温度域）〕で記憶保持できる色彩記憶保持型熱変色性インキが適用されることが好ましい。図３において、ΔＨは、ヒステリシスの程度を示す温度幅（即ちヒステリシス幅）を示す。ΔＨの値が小さいと、変色前後の両状態のうち一方の状態しか存在しえない。ΔＨの値が大きいと、変色前後の各状態の保持が容易となる。 In the present invention, as shown in FIG. 3, the shape of the curve plotting the change in color density due to the temperature change is opposite to the case where the temperature is raised from the lower temperature side than the color change temperature range, and from the higher temperature side than the color change temperature range. The color changes by following a different path depending on the descending state, and the color development state in the low temperature range below the complete color development temperature (t 1 ) or the color erase state in the high temperature range above the complete color erase temperature (t 4 ) It is preferable to apply a color memory retention type thermochromic ink that can be stored and retained in a specific temperature range [temperature range between t 2 and t 3 (substantially two-phase retention temperature range)]. In FIG. 3, ΔH indicates a temperature width (ie, hysteresis width) indicating the degree of hysteresis. When the value of ΔH is small, only one of the two states before and after the color change can exist. When the value of ΔH is large, it is easy to maintain each state before and after the color change.

Accordingly, it is possible to effectively maintain the color exhibited in the normal state (daily life temperature range), and it is possible to easily change the handwriting by the reversible thermochromic ink with the frictional heat generated by the friction portion.

前記可逆熱変色性マイクロカプセル顔料は、粒子径の平均値が０．５〜５．０μｍ、好ましくは１〜４μｍの範囲にあることが好ましい。平均粒子径が５．０μｍを越える系では、ボールペンチップや多孔質ペン体の毛細間隙からの流出性が低下し、平均粒子径が０．５μｍ以下の系では高濃度の発色性を示し難くなる。 The reversible thermochromic microcapsule pigment preferably has an average particle diameter in the range of 0.5 to 5.0 μm, preferably 1 to 4 μm. When the average particle diameter exceeds 5.0 μm, the outflow from the capillary gap of the ballpoint pen tip or the porous pen body decreases, and when the average particle diameter is 0.5 μm or less, it is difficult to show high density color development. .

前記可逆熱変色性マイクロカプセル顔料は、インキ組成物全量に対し、２〜５０重量％（好ましくは３〜４０重量％、更に好ましくは、４〜３０重量％）配合することができる。２重量％未満では発色濃度が不充分であり、５０重量％を越えるとインキ流出性が低下し、筆記性が阻害される。 The reversible thermochromic microcapsule pigment can be blended in an amount of 2 to 50% by weight (preferably 3 to 40% by weight, more preferably 4 to 30% by weight) based on the total amount of the ink composition. If it is less than 2% by weight, the color density is insufficient, and if it exceeds 50% by weight, the ink outflow is reduced and the writing property is impaired.

本発明の摩擦具は、所望する熱変色面積に適した外形状を有する摩擦部を選択して使用することができる。 The friction tool of the present invention can be used by selecting a friction part having an outer shape suitable for a desired thermal discoloration area.

That is, since the friction tool 1 of the first invention includes two types of friction portions (the first friction portion 41 and the second friction portion 51) having different outer shapes, the outer surface suitable for the desired thermal discoloration area. A friction part (first friction part 41 or second friction part 51) having a shape can be selected and used.

本実施の形態の摩擦具１は、第１の摩擦部４１の外形状と第２の摩擦部５１の外形状とが異なること(即ち、一定荷重で押圧した時の被筆記面との接触面積が第１の摩擦部４１と第２の摩擦部５１とで異なること)により、大面積の熱変色性インキの筆跡を熱変色させる場合には、一定荷重における被筆記面との接触面積の大きい摩擦部（例えば外形状の外径の大きい第１の摩擦部４１または凸曲面状の頂部の曲率半径が大きい第１の摩擦部４１）を選択して使用でき、一方、小面積の熱変色性インキの筆跡を熱変色させる場合には、一定荷重における被筆記面との接触面積の小さい摩擦部（例えば外形状の外径の小さい第２の摩擦部５１または凸曲面状の頂部の曲率半径が小さい第２の摩擦部５１）を選択して使用できる。それにより、前記摩擦具１は、所望する熱変色面積に適した外形状を有する摩擦部（第１の摩擦部４１または第２の摩擦部５１）を選択して使用することができる。 In the friction tool 1 of the present embodiment, the outer shape of the first friction portion 41 is different from the outer shape of the second friction portion 51 (that is, the contact area with the writing surface when pressed with a constant load). Is different between the first friction part 41 and the second friction part 51), when the handwriting of the large-area thermochromic ink is thermally discolored, the contact area with the writing surface at a constant load is large. A friction part (for example, a first friction part 41 having a large outer diameter or a first friction part 41 having a large curvature radius at the top of a convex curved surface) can be selected and used, while a small area thermochromic property. When the ink handwriting is subjected to thermal discoloration, the friction part having a small contact area with the writing surface under a constant load (for example, the second friction part 51 having a small outer diameter of the outer shape or the radius of curvature of the top of the convex curved surface is required). A small second friction part 51) can be selected and used. Thereby, the friction tool 1 can select and use the friction part (the first friction part 41 or the second friction part 51) having an outer shape suitable for a desired thermal discoloration area.
