Title (EN) INK COMPOSITION FOR INKJET PRINTING
(FR) COMPOSITION D’ENCRE POUR IMPRESSION À JET D’ENCRE
(JA) インクジェット印刷用インク組成物
Abstract:
(EN) An ink composition for inkjet printing that in the printing by means of an inkjet printer, is free from nozzle clogging to thereby enable obtaining a print of desirable printing quality, and that can ensure appropriate drying rate for printing and further excels in color development. There is provided an ink composition for inkjet printing, comprising a pigment, a binder resin, a pigment dispersant and a solvent, wherein the solvent is composed of (1) at least one glycol ether and at least one of a lactone compound and 2-pyrrolidone, or (2) at least one glycol ether acetate and at least one of cyclohexanone and isophorone.
(FR) L’invention porte sur une composition d’encre pour impression à jet d’encre qui, pour une impression avec imprimante à jet d’encre, est libérée de toute obstruction de la buse de projection, permettant ainsi obtenir une impression de qualité voulue et susceptible de garantir une vitesse de séchage appropriée, avec un excellent développement des couleurs. La composition d’encre pour impression à jet d’encre selon l’invention comprend un pigment, une résine de liant, un dispersant de pigment et un solvant, le solvant se composant (1) d’au moins un éther de glycol et d’au moins un élément entre un composé de lactone et un 2-pyrrolidone, ou (2) d’au moins un acétate d’éther glycol et d’au moins un élément entre un cyclohexanone et un isophorone.
(JA)   本発明はインクジェットプリンタにより印刷する際にノズルの詰まりが生じることがないので印字品質上好ましい印刷物が得られ、印字の適度な乾燥速度が得られ、また色の発現に優れているインクジェット印刷用インク組成物を提供する。本発明のインクジェット印刷用インク組成物は、顔料、バインダー樹脂、顔料分散剤及び溶媒からなり、該溶媒が(1)グリコールエーテルの少なくとも1種とラクトン化合物及び2-ピロリドンの少なくとも1種とからなるか、又は(2)グリコールエーテルアセテートの少なくとも1種とシクロヘキサノン及びイソホロンの少なくとも1種とからなる。
