    • An aqueous ink for a transfer ink jet recording method including applying to an intermediate transfer member a reaction liquid which forms an increased viscosity ink image by coming into contact with a coloring material in the ink, applying the ink to the intermediate transfer member by an ink jet device to form an intermediate image, and bringing a printing object into contact with the intermediate transfer member to transfer the image to the object. The aqueous ink contains a coloring material which is a polymer dispersion pigment dispersed in the aqueous medium with a polymer having a hydroxyl group in its structure as a dispersant, a nonionic surfactant which is an alcohol ether surfactant a 1% aqueous solution of which has a cloud point of 33° C. or less and which has a C4-C30 alkyl group and a propyleneoxy group in its structure, and an aqueous medium.
    • 一种用于转印喷墨记录方法的水性油墨,其特征在于,向中间转印部件施加通过与油墨中的着色材料接触形成增加粘度的油墨图像的反应液体,通过油墨将油墨施加到中间转印部件 喷墨装置形成中间图像,并且使打印对象与中间转印部件接触以将图像转印到对象。 水性油墨含有作为分散在其结构中具有羟基的聚合物作为分散剂的水性介质中分散的聚合物分散颜料的着色材料,1%水溶液中的醇醚表面活性剂的非离子表面活性剂,其具有 浊点为33℃以下,其结构中具有C4-C30烷基和丙烯氧基,以及水性介质。

    • A recording head and a recording unit are provided achieving both the reliability of ejection stability and storage stability and the prevention of a new color mixing phenomenon. The recording head has ejection orifice lines each of which ejects each of the inks constituting an ink set. The plurality of inks is stored respectively in ink cartridges each having an ink storage portion being brought into a hermetically-closed state. At least three types of inks among the inks are different in specific gravity from one another, and at least two types of inks among the at least three types of inks are different in specific gravity by 0.020 or more. The ejection orifice lines are arranged so that the total sum of differences in specific gravities between the inks to be ejected from ejection orifice lines adjacent to each other among the inks to be ejected from the ejection orifice lines becomes minimal.
    • 提供了记录头和记录单元,其实现了喷射稳定性和储存稳定性的可靠性以及防止新的混色现象。 记录头具有喷射孔线,每个排出口排出构成油墨组的每个油墨。 多个墨水分别存储在各自具有墨水储存部分进入气密封闭状态的墨盒中。 油墨中至少有三种类型的油墨在比重上彼此不同,并且至少三种类型的油墨中的至少两种类型的油墨在比重上不同,为0.020以上。 喷射孔线被布置成使得从喷射孔线喷射的油墨中彼此相邻的喷射孔管线喷射的油墨之间的比重差的总和变得最小。
