Title (EN) WATER-SOLUBLE PHTHALOCYANINE DYE, WATER-BASED INK COMPOSITION AND NEAR INFRARED ABSORBING AGENT
(FR) COLORANT PHTALOCYANINE HYDROSOLUBLE, COMPOSITION D'ENCRE AQUEUSE ET AGENT ABSORBANT DANS LE PROCHE INFRAROUGE
(JA) 水溶性フタロシアニン色素、水系インク組成物及び近赤外線吸収剤
Abstract: front page image
(EN)Disclosed are a water-soluble phthalocyanine dye represented by general formula (1), or a salt thereof (1) (in the formula, M represents a metal atom or the like, R represents a sulpho group or carboxy group, m represents an integer from 0 to 2, n represents an integer from 12 to 16, and p represents an integer from 0 to 4), and a water-based ink composition containing at least one such dye or a salt thereof. It is possible to offer simply and at low cost a phthalocyanine dye which absorbs in the near infrared region and is outstandingly water soluble, and to offer a water-based ink composition with outstanding storage stability, containing such a dye.
(FR)Cette invention concerne un colorant phtalocyanine hydrosoluble représenté par la formule générale (1), ou un de ses sels (1) (dans la formule, M représente un atome métallique ou autre atome similaire, R représente un groupe sulfo ou un groupe carboxy, m représente un nombre entier entre 0 et 2, n représente un nombre entier entre 12 et 16, et p représente un nombre entier entre 0 et 4), et une composition d'encre aqueuse contenant au moins ledit colorant ou sel de celui-ci. Selon l'invention, il est possible de proposer simplement et à bas coût un colorant phtalocyanine qui absorbe la lumière dans le proche infrarouge et est exceptionnellement hydrosoluble, et de proposer une composition d'encre aqueuse ayant une exceptionnelle stabilité en stockage et contenant ledit colorant.
(JA) 本発明は、下記式(1)で表される水溶性フタロシアニン色素又はその塩(式中、Mは金属原子等、Rはスルホ基又はカルボキシ基を表し、mは0乃至2、nは12乃至16、pは0乃至4の整数を、それぞれ表す。)、及び、当該色素又はその塩の少なくとも1種を含有する水系インク組成物に関する。本発明により、簡便かつ低コストで、近赤外領域に吸収を有し、水溶性に優れたフタロシアニン色素、及び、該色素を含有し、貯蔵安定性に優れた水系インク組成物を提供することができる。
