Title (EN) INKJET INK AND IMAGE FORMING METHOD
(FR) ENCRE POUR IMPRESSION PAR JET D'ENCRE ET PROCÉDÉ DE FORMATION D'IMAGE
(JA) インクジェットインク及び画像形成方法
Abstract:
(EN) Disclosed is an inkjet ink which has excellent ejection stability and reduced moisture dependence during image formation, and is capable of providing images having excellent adhesion and flexibility. Also disclosed is an image forming method using the inkjet ink. The inkjet ink is composed of a photocurable inkjet ink that contains a coloring material, a photopolymerizable compound and a polymerization initiator. The photocurable inkjet ink is characterized in that the photopolymerizable compound contains a compound that has a molecular weight of 100 or more but less than 2,000 and contains a vinyl ether group, and a polymer compound that has a weight average molecular weight of not less than 2,000 but not more than 100,000 and contains a group represented by general formula (1) in a side chain.
(FR) Cette invention concerne une encre pour impression par jet d'encre qui a une excellente stabilité à l'éjection et une dépendance à l'humidité réduite pendant la formation d'image, et est capable de donner des images ayant une excellente adhérence et flexibilité. L'encre pour impression par jet d'encre selon l'invention est composée d'une encre pour impression par jet d'encre photodurcissable qui contient un matériau colorant, un composé photopolymérisable et un initiateur de polymérisation. L'encre pour impression par jet d'encre photodurcissable est caractérisée en ce que le composé photopolymérisable contient un composé qui a un poids moléculaire de 100 ou plus mais inférieur à 2000 et contient un groupe éther de vinyle, et un composé polymère qui a un poids moléculaire moyen en poids qui n'est pas inférieur à 2000 mais pas supérieur à 100 000 et contient un groupe représenté par la formule générale (1) dans une chaîne latérale.
(JA)  本発明は、吐出安定性に優れ、画像形成時の湿度依存性が少なく、密着性と柔軟性に優れた画像が得られるインクジェットインクと、それを用いた画像形成方法を提供する。このインクジェットインクは、色材、光重合性化合物及び重合開始剤を含有する光硬化性のインクジェットインクにおいて、該光重合性化合物が、分子量が100以上、2000未満のビニルエーテル基を有する化合物と、側鎖に下記一般式(1)で表される基を有し、重量平均分子量が2000以上、100000以下である高分子化合物とを含有することを特徴とする。
