Abstract
【解決手段】少なくとも着色材と、ワックス、樹脂などの形成材および体質材と油材から成る固形描画材において、油材として中鎖脂肪酸トリグリセリド、具体的にはカプリル酸トリグリセリド、カプリン酸トリグリセリドなど、また体質材として微粉末シリコーンゴム弾性体を用い、着色材、形成材と共にこれらを混合し、ニーダーにて十分に混練し、得られた混練物を押出成形して固形描画材とする。
Description
パラフィンワックス 10部
カプリル酸トリグリセリド 15部
微粉末シリコーンゴム弾性体(平均粒径2μmで球状) 30部
ピグメントレッド122 30部
上記成分を混合し、ニーダーにて十分に加熱混練して混練物を作製し、この混練物を押出成形して直径8mm、長さ60mmの赤色の固形描画材を得た。
実施例1において、カプリル酸トリグリセリドの代わりに脂肪酸トリグリセリドを構成する脂肪酸の代表組成がヒドロキシ酸であるヒマシ硬化油(12ヒドロキシステアリン酸)を用い、かつ微粉末シリコーンゴム弾性体の代わりにタルクを用いた以外は、実施例1と同様の材料および工程を用いて赤色の固形描画材を得た。
実施例1において、カプリル酸トリグリセリドの代わりに脂肪酸トリグリセリドを構成する脂肪酸の代表組成として炭素数が10を超えるものである牛脂硬化油を用い、かつ微粉末シリコーンゴム弾性体の代わりにタルクを用いた以外は、実施例1と同様の材料および工程を用いて赤色の固形描画材を得た。
実施例1において、カプリル酸トリグリセリドの代わりに非イオン界面活性剤であるポリオキシエチレンポリオキシプロピレンセチルエーテルを用い、かつ微粉末シリコーンゴム弾性体の代わりにタルクを用いた以外は、実施例1と同様の材料および工程を用いて赤色の固形描画材を得た。
Claims (4)
