Description
ステアリン酸アミド 25部
ポリプロピレングリコール(分子量1000) 15部
着色材(有機蛍光顔料…ピンク色) 10部
体質材(タルク) 20部
上記材料を用い、まず着色材、体質材以外の材料を混合して、85℃に加熱溶解したのち、着色材と体質材を加えてさらに溶解し、所定の型内に流し込み、冷却・固化して外径8mmφ、長さ60mmの蛍光ピンク色の固形描画材を得た。この固形描画材は、紙面上において描画性、消去性が良好であり、しかも描画後1週間経過しても消しゴムによる消去性は変わらない。
カルナバワックス37部、ステアリン酸アミド33部、有機蛍光顔料(ピンク色)10部、タルク20部を用いて実施例1と同様の方法にて蛍光ピンク色の固形描画材を得た。この固形描画材で描画された画線の消去性は、当初から十分なものではなく、1週間経過したあとには消去不能となった。
Claims (1)
- 少なくとも形成材と脂肪酸アミドと着色材とからなり、前記着色材の平均粒径が5〜30μmで、かつ前記素材の他にポリプロピレングリコールを配合して当初の消去性を持続させることを特徴とする固形描画材。
