Description
本発明における最も重要な点は、白色無機粒子粉末の粒子表面に表面改質剤を介してカーボンブラックもしくは顔料誘導体処理カーボンブラックが付着しており、更にその表面が顔料誘導体に被覆されている帯電制御材は、所要の電気抵抗値が容易に得られると共に、優れた分散性を有するという事実である。
2:帯電制御材100個当たりに30個以上50個未満。
3:帯電制御材100個当たりに10個以上30個未満。
4:帯電制御材100個当たりに5個以上10個程度。
5:帯電制御材100個当たりに5個未満。
体積固有抵抗値(Epn)(Ω・cm)=R×(A/t0)
体積固有抵抗値の変化率log(Epl/Epn)=|log(Epl/Epn)|
体積固有抵抗値の変化率log(Eph/Epn)=|log(Eph/Epn)|
塗料粘度の変化率(%)={(V1−V0)/V0}×100
