Title (EN) INK COMPOSITION AND IMAGE FORMATION METHOD
(FR) COMPOSITION D'ENCRE, ET PROCÉDÉ DE FORMATION D'IMAGE
(JA) インク組成物及び画像形成方法
Abstract:
(EN) Provided are an ink composition and an image formation method using said ink composition, said ink composition containing: a pigment indicated by formula (1); a polymer dispersant including a repeating unit having a hydrophilic group and a repeating unit having an aromatic group; polymer particles including a repeating unit having a hydrophilic group and a repeating unit having an cyclic aliphatic group; and water. Z indicates a 5-member heterocycle or 6-member heterocycle that may have a substituted group. Y1, Y2, R11, and R12 each independently indicate a hydrogen atom or a substituted group. G1 and G2 each independently indicate a hydrogen atom or a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group. W1 and W2 each independently indicate a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group.
(FR) L'invention fournit une composition d'encre, et un procédé de formation d'image mettant en œuvre cette composition d'encre. Ladite composition d'encre comprend : un pigment représenté par la formule (1) ; un agent de dispersion polymère qui contient une unité de répétition ayant un groupe hydrophile et une unité de répétition ayant un groupe aromatique ; des particules polymères qui contiennent une unité de répétition ayant un groupe hydrophile et une unité de répétition ayant un groupe aliphatique cyclique ; et une eau. Z peut avoir un substituant, et représente un hétérocycle à 5 chaînons ou un hétérocycle à 6 chaînons. Y, Y, R11 et R12 représentent chacun indépendamment un atome d'hydrogène ou un substituant. G et G représentent chacun indépendamment un atome d'hydrogène, un groupe alkyle substitué ou non substitué, un groupe aralkyle substitué ou non substitué, un groupe alcényle substitué ou non substitué, un groupe alcynyle substitué ou non substitué, un groupe aryle substitué ou non substitué, ou un groupe hétérocyclique substitué ou non substitué. W et W représentent chacun indépendamment un groupe alcoxy substitué ou non substitué, un groupe amino substitué ou non substitué, un groupe alkyle substitué ou non substitué, ou un groupe aryle substitué ou non substitué.
(JA) 本発明は、式(1)で表される顔料、親水性基を有する繰り返し単位と芳香族基を有する繰り返し単位とを含むポリマー分散剤、親水性基を有する繰り返し単位と環状脂肪族基を有する繰り返し単位とを含むポリマー粒子、及び水を含有するインク組成物、及び上記インク組成物を用いる画像形成方法を提供する。 Zは置換基を有していてもよい、5員ヘテロ環又は6員ヘテロ環を表す。Y、Y、R11及びR12は、それぞれ独立に水素原子又は置換基を表す。G及びGは、それぞれ独立に水素原子、置換若しくは無置換のアルキル基、置換若しくは無置換のアラルキル基、置換若しくは無置換のアルケニル基、置換若しくは無置換のアルキニル基、置換若しくは無置換のアリール基、又は置換若しくは無置換のヘテロ環基を表す。W及びWは、それぞれ独立に置換若しくは無置換のアルコキシ基、置換若しくは無置換のアミノ基、置換若しくは無置換のアルキル基、又は置換若しくは無置換のアリール基を表す。
