Abstract

　高いε化率を有するε型銅フタロシアニン顔料とその製造方法を提供する。またそれを用い調製することで、カラーフィルター用青色着色部が従来より輝度、コントラストに優れる顔料を提供する。 　広角Ｘ線回折スペクトルに基づき次式により算出される結晶のε化率が８０～９０であることを特徴とするε型銅フタロシアニン顔料、およびそのε型銅フタロシアニン中間体顔料と微細化されたε型銅フタロシアニン微細顔料を製造する。 式　ε化率＝（１－Ａ／Ｂ）×１００ （ただしＡは、ブラッグ角２θ＝６．８°±０．１°におけるピークの絶対強度、Ｂはブラッグ角２θ＝７．６°±０．１°におけるピークの絶対強度を表す。）。
