Abstract

本発明は、トラックピッチ５０～５００ｎｍのプリグルーブを表面に有する基板の該表面上に下記一般式（Ａ）で表されるアゾ金属錯体色素を含有する記録層を有する光情報記録媒体を提供する。 一般式（Ａ） Ａ・（Xp+）k' 　　一般式（Ａ）中、Ａは、（L2-）2（M）で表されるアニオン性部位を表し、Ｌ2-は２価のアゾ色素アニオンを表し、Ｍは金属イオンまたは金属酸化物イオンを表す。Ｘp+は、Ｃｌ-等と塩形成した場合に、３５０～７００ｎｍの波長領域における最大のモル吸光係数が２００００ｄｍ3ｍｏｌ-1ｃｍ-1未満であるｐ価の有機カチオンを表し、ｐは１～１０の範囲の整数を表し、ｋ’は０＜ｋ’≦４の範囲であって、Ａで表されるアニオン性部位中の負電荷をｐで割った値を表す。但し、Ｘp+が非環状のアルキルアンモニウムカチオンである場合を除く。
