Abstract:
(EN) An ink composition that includes microcapsules, a colorant, and water. The microcapsules have a shell and a core. The shell has a three-dimensional cross-linked structure that includes urethane linkages and/or urea linkages. The core is encapsulated by the shell. The colorant is selected from colorants that have an ionic group and colorants that are coated with a dispersant that has an ionic group on at least one portion of the surface thereof. The content ratio of an acid-group-containing compound that has at least one acidic group, an acid dissociation constant of 5 or lower, and a molecular weight of 2000 or lower is 0.5 mass% or lower with respect to the total mass of the ink composition. An ink set, an ink composition production method, and an image recording method.
(FR) La présente invention concerne une composition d’encre qui comprend des microcapsules, un colorant et de l’eau. Les microcapsules comportent une enveloppe et un noyau. L’enveloppe a une structure réticulée tridimensionnelle qui comprend des groupes de liaison uréthane et/ou des groupes de liaison urée. Le noyau est encapsulé par l’enveloppe. Le colorant est choisi parmi des colorants qui comportent un groupe ionique et des colorants qui sont revêtus avec un dispersant qui comporte un groupe ionique sur au moins une partie de la surface de celui-ci. Le rapport de teneur d’un composé contenant un groupe acide qui a au moins un groupe acide, une constante de dissociation acide de 5 ou moins, et un poids moléculaire de 2000 ou moins est de 0,5 % en masse ou moins par rapport à la masse totale de la composition d’encre. L’invention concerne en outre un ensemble d’encre, un procédé de production de composition d’encre et un procédé d’enregistrement d’image.
(JA) ウレタン結合及びウレア結合の少なくとも一方を含む三次元架橋構造を有するシェル並びにシェルに内包されたコアを有するマイクロカプセルと、イオン性基を有する着色剤及び表面の少なくとも一部がイオン性基を有する分散剤で被覆された着色剤から選択される着色剤と、水と、を含み、少なくとも酸性基を有し、かつ、酸解離定数が5以下である分子量2000以下の酸性基含有化合物の、インク組成物全質量に対する含有比率が0.5質量%以下であるインク組成物、インクセット、及びインク組成物の製造方法、並びに画像記録方法である。
