Title (EN) AQUEOUS DYE DISPERSION FOR AQUEOUS INKS, AND AQUEOUS INK
(FR) DISPERSION AQUEUSE DE COLORANT POUR ENCRES AQUEUSES, ET ENCRE AQUEUSE
(JA) 水性インク用水系染料分散体及び水性インク
Abstract:
(EN) Provided is an aqueous dye dispersion for aqueous inks, which includes a dye derivative indicated by formula (1), a water-insoluble dye, a dispersant, and water, and thereby which suppresses, even when an aqueous ink is prepared, aggregation of particles in the aqueous ink, and exhibits high dispersion stability during storage. (In formula (1), R1 represents a group indicated by formula (2), R2 represents a group indicated by formula (3), m and n are each 0 or 1 and satisfy m+n=1, and R3 is at least one selected from a hydroxyl group and an amino group. "l" equals 0-2. When l equals 2, each R3 may be identical or different.) (In formula (3), R4 represents an alkylene group or a phenylene group having 1-4 carbon atoms, and R5 and R6 each represent an independently selected alkyl group having 1-4 carbon atoms).
(FR) L'invention concerne une dispersion aqueuse de colorant pour encres aqueuses, qui comprend un dérivé de colorant représenté par la formule (1), un colorant insoluble dans l'eau, un dispersant et de l'eau, et permet par conséquent de supprimer, même lors de la préparation d'une encre aqueuse, l'agrégation de particules dans l'encre aqueuse, ladite dispersion présentant une stabilité de dispersion élevée au stockage. (Dans la formule (1), R1 représente un groupe représenté par la formule (2), R2 représente un groupe représenté par la formule (3), m et n représentent chacun 0 ou 1 et satisfont la relation m + n = 1, et R3 représente un groupe hydroxyle et/ou un groupe amino. "l" égale 0-2. Quand l égale 2, chaque R3 peut être identique ou différent). (Dans la formule (3), R4 représente un groupe alkylène ou un groupe phénylène comportant 1-4 atomes de carbone, et R5 et R6 représentent chacun un groupe alkyle choisi indépendamment comportant 1-4 atomes de carbone).
(JA) 下記式(1)で示される染料誘導体、水不溶性染料、分散剤及び水を含む水性インク用水系染料分散体により、水性インクを調製した時にも、水性インク中の粒子が凝集することを抑制し、保存時の分散安定性が良好な水性インク用水系染料分散体を提供することができる。(式(1)中、Rは下記式(2)で示される基であり、Rは下記式(3)で示される基である。m及びnは何れも0又は1で且つm+n=1である。Rはヒドロキシル基およびアミノ基から選択される少なくとも1種である。l=0~2であり、l=2の場合は、Rはそれぞれ異なっていても、同じでもよい。)(式(3)中、Rは、炭素数1~4のアルキレン基又はフェニレン基であり、R及びRは独立して選択される炭素数1~4のアルキル基である。)
