Abstract
(EN)
The problem addressed by the invention is to provide a novel near infrared-absorbing cyanine pigment and a near infrared absorbent comprising same. The problem is solved by providing a benzo [c,d] indolium heptamethine cyanine pigment represented by formula (1) and a near infrared absorbent comprising same. (In formula (1), R1 and R2 each independently represent C1-5 straight or branched alkyl groups. R3 and R4 each independently represent hydrogen atoms or substituting groups. X- represents a counter anion.)
(FR)
Cette invention a pour objectif de procurer un nouveau pigment cyanine absorbant dans le proche infrarouge et un absorbant dans le proche infrarouge le contenant. Pour ce faire, cette invention procure un pigment cyanine de type heptaméthine de benzo[c,d]indolium représenté par la formule (1) et un absorbant dans le proche infrarouge le contenant. (Dans la formule (1), R1 et R2 représentent chacun indépendamment des groupes alkyle C1-5 linéaires ou ramifiés. R3 et R4 représentent indépendamment des atomes d'hydrogène ou des groupes de substitution. X- représente un contre-anion).
(JA)
 新規な近赤外線吸収シアニン色素及びそれを含む近赤外線吸収剤を提供することを課題とする。下記一般式1で表されるベンゾ[cd]インドリウム系ヘプタメチンシアニン色素、及びこれを含有する近赤外線吸収剤を提供することにより上記課題を解決するものである。 (一般式1において、R、Rは、それぞれ独立に炭素数1乃至5の直鎖状又は分岐を有するアルキル基を表す。R、Rはそれぞれ独立に水素原子又は置換基を表す。Xは、対アニオンを表す。)
