先端にボールペンチップ(ボール径:0.7mm)を備えた図1に示すものと同様のボールペンのポリプロピレン製の円筒状インキ収容管(内径4.0mm)に、各実施例、比較例及び参考例で得られたインキ組成物を収容した。次に、そのインキ収容管内のボールペンチップとは反対側(インキ組成物の後端面側)に、上記インキ組成物と隣接するように、精製鉱油95質量%と増稠剤(金属石鹸、エラストマー)5質量%とからなる逆流防止体を充填した。そして、ボールペンの本体軸の後端に尾栓を取り付け、ボールペンを作製した。なお、各実施例、比較例及び参考例ごとに、8本ずつボールペンを作製した。
上述の「初筆かすれの評価」と同様にして、ボールペンを作製した。作製したボールペンを筆記試験機に取り付けて、筆記角度70°、荷重200g、筆記速度4m/分の条件でループを筆記した。筆記線を目視にて観察してボテ(ボタ)の有無を評価した。ボテが殆どなく気にならないもの「A」、「A」よりもボテが大きいものを「B」と評価した。結果を表4及び表5に示す。
上述の「初筆かすれの評価」と同様にして、ボールペンを作製した。作製したボールペンを用いてフリーハンドで筆記し、書き味を以下の評価基準に基づいて評価した。その結果を表4及び表5に示す。
A:滑らかである。
B:滑らかさが十分でなく、重い。
調製したインキ組成物を、光学顕微鏡(倍率:200倍)で観察して、分散状態を観察することによって乳化安定性を評価した。光学顕微鏡による観察は、水性ゲルインキの作製直後と室温(25℃)で2ヶ月間保管後の2回行い、以下の評価基準に基づいて評価した。
A:油性成分中に水性成分が均一に分散しており、分散状態が良好である。
B:油性成分中における水性成分の分散状態がやや不均一である。
C:油性成分中における水性成分の分散状態に不均一な部分が見られる。
