Abstract

水溶性アクリル樹脂塗料系における親水性顔料 (酸化チタン) および疎水性顔料 (銅フタロシアニンブルー) の分散性について検討した。疎水性顔料の場合には, より親水性の方が, 親水性顔料の場合には, より疎水性の方が光沢の高い塗膜が得られた。このことから疎水性顔料の場合にはぬれが, 親水性顔料の場合には分散の安定化が, それぞれ分散進行の律速過程であり, 分散の安定化は疎水性相互作用による樹脂の顔料への吸着によってはかられていると考えられる。顔料の選択においては, 分散の安定化とぬれの2つの過程は相反する事象であり, 水に対する湿潤熱が0.1~0.2J/m2程度の親水性度を持つ顔料で最も良好な分散性を得ることができると考えられる。
