Title
(EN) WATER-BASED INK FOR INKJET RECORDING AND INK CARTRIDGE
(FR) ENCRE AQUEUSE POUR ENREGISTREMENT À JET D'ENCRE, ET CARTOUCHE D'ENCRE
(JA) インクジェット記録用水性インク及びインクカートリッジ
Abstract
(EN) Provided is a water-based ink for inkjet recording that is capable of improving the optical density (OD value) of a recorded article written with the water-based ink without the need to increase the colorant concentration. The water-based ink for inkjet recording, according to the present invention, is characterized by including: a colorant; water; an acidic preservative; and at least one of a surfactant and a penetrant. The acidic preservative includes, for example, at least one of: polyunsaturated fatty acid or polyunsaturated fatty acid salt; and dehydroacetic acid or dehydroacetic acid salt.
(FR) L'invention fournit une encre aqueuse pour enregistrement à jet d'encre qui permet d'améliorer la densité optique (valeur DO) d'un objet enregistré à l'aide d'une encre aqueuse, sans augmenter la concentration en agent colorant. L'encre aqueuse pour enregistrement à jet d'encre de l'invention est caractéristique en ce qu'elle contient un colorant, une eau, un agent de conservation acide, et un agent tensio-actif et/ou un agent pénétrant. Ledit agent de conservation acide contient, par exemple, au moins un acide gras insaturé polyvalent, un sel d'acide gras insaturé polyvalent, un acide déhydro-acétique ou un sel d'acide déhydro-acétique.
(JA) 着色剤濃度を高めずとも、水性インクによる記録物の光学濃度(OD値)を向上させることが可能なインクジェット記録用水性インクを提供する。本発明のインクジェット記録用水性インクは、染料と、水と、酸性防腐剤と、界面活性剤及び浸透剤のうち少なくとも一つと、を含むことを特徴とする。前記酸性防腐剤は、例えば、多価不飽和脂肪酸、多価不飽和脂肪酸塩、デヒドロ酢酸、及びデヒドロ酢酸塩の少なくとも一方を含む。
