Embodiment

[0233] The present invention will be further illustrated below by examples, but the present invention is not limited by these examples. In these embodiments, image recording is also referred to as printing or printing.

[0234]

[0235] In the process of preparing the ink composition, the kind and quantity of the coloring agent, organic solvent and surfactant and the content of binder resin and water are changed as shown in Table 1 to obtain the relational expression satisfying the important conditions of the present invention (1) The ink compositions of Examples 1 to 7 and the ink compositions of Comparative Examples 1 to 4 that do not satisfy the relational expression (1) of the present invention. In Table 1, the units of values ​​in each column are expressed in parts by weight, and the total amount of each ink composition in Examples 1 to 7 and Comparative Examples 1 to 4 is 100 parts by weight. Furthermore, in Table 1, TEGBE represents triethylene glycol monobutyl ether...

Abstract

The ink composition 60 is produced in such a way that the difference between dynamic surface tension(mN / m) and static surface tension(mN / m) determined at 24-26[deg.]C by maximum foam pressure method is 0-7(mN / m). The printing method comprises the following process. The ink composition 60 is reserved in the ink tank 50 of the ink head 1 and fed from the ink tank 50 into an ink chamber 40 with a jet nozzle 31, voltage is applied on a diaphragm section 12 formed of a piezoelectric material and pressure is applied on the ink composition 60 filled in the ink chamber 40 through the diaphragm section 12 to jet droplets of the ink composition 60 via the jet nozzle 31, and the droplets are put on a printing material to print images on the printing material.

Description

technical field [0001] The present invention relates to an ink composition suitable for an inkjet recording method, a recording method and a recorded image using the ink composition, an ink set, and an ink head. Background technique [0002] The inkjet recording method is a method of releasing and flying droplets of an ink composition (hereinafter also simply referred to as "ink") by kinetic energy or thermal energy, and making such droplets adhere to a recording material such as paper to record an image. Methods. [0003] Heretofore, the characteristics of the ink used in the inkjet recording method (hereinafter also referred to as "inkjet ink") can be expressed by physical properties such as surface tension or viscosity. Attempts have been made to adjust the drying properties of inks or to improve the quality of formed images by limiting these physical properties. [0004] For example, there has been proposed an inkjet recording method which defines an ink droplet by the...
