Problems solved by technology

However, although the cleaning of foreign matter in the flow path reduces the adhesion of air bubbles to it, it cannot reduce the adhesion to the member itself, and it is expected to solve this problem.

Embodiment

[0043] Hereinafter, the present invention will be described more specifically by listing examples and comparative examples of the present invention, but the present invention is not limited to these examples.

[0044] [Preparation of Liquid Composition Containing Diacetylene Tetraol Compound]

[0045] As the aforementioned liquid composition, each of the liquid compositions shown in Table 1 and Table 2 containing the diacetylene tetraol compound represented by the above general formula (1) was prepared. Specifically, it is produced by fully mixing and dissolving each component raw material in a solvent, and pressure-filtering it with a membrane filter with a pore size of about 0.8 μm. For each of the obtained liquid compositions, evaluation of bubble adhesion was performed. The evaluation method will be described later. The results are shown in Table 1 and Table 2.

Abstract

A liquid composition for preventing bubble adhesion, containing a diacetylene tetraol compound expressed by the following General Formula (1): (where R 1 and R 2 are each independently a C 1 to C 3 alkyl group, -O-Et- is an oxyethylene group, and k, l, m, and n are each an integer from 0 to 2).

Description

technical field [0001] The present invention relates to a novel liquid composition for preventing bubble adhesion suitable for inkjet recording. Normal ejection is possible due to adverse effects caused by adhesion of road-forming members. Background technique [0002] The inkjet recording method is a printing method in which small droplets of ink are ejected from fine nozzle heads, dispersed, adhered to a recording medium such as paper, and printed. This method is characterized by high-speed printing of high-resolution and high-quality images with an inexpensive device. Therefore, an inkjet recording apparatus using this method has been widely favored commercially because of good printing quality, low cost, quieter operation, and image forming ability. Among them, thermal (Bubble Jet (registered trademark)) and piezoelectric drop-on-demand (Drop-On-Demand) printers are particularly successful in the market, and are widely used as office and home computer printers.
