Claims (3)
- 固体粉末を水に溶解させて水溶液を調製する工程と、この水溶液を油性成分中に分散させて(W/O)分散系を調製する工程と、この(W/O)分散系の水分を蒸発させることにより油性成分中に固体粉末を析出させて(S/O)分散系を得る工程と、この(S/O)分散系を水相中に分散させて(S/O)/W分散系を調製する工程と、この(S/O)/W分散系を冷却して油性成分を固化させることにより固体粉末含有マイクロカプセルを得る工程とを備えるとともに、前記(W/O)分散系の水相中に固体粉末の貧溶媒が含まれていることを特徴とする固体粉末含有マイクロカプセルの製造方法。
- (S/O)分散系を得る工程において、油性成分中に温度応答性樹脂を溶融させることを特徴とする請求項1記載の固体粉末含有マイクロカプセルの製造方法。
- (S/O)分散系を得る工程において、溶融させる温度応答性樹脂の量を調整することによりマイクロカプセルの温度応答性を制御することを特徴とする請求項2記載の固体粉末含有マイクロカプセルの製造方法。
