Problems solved by technology

In this case, the ejection of ink droplets ejected from the recording head tends to become unstable, and image confusion tends to occur in the formed image.
In addition, depending on the type of wetting agent, when the recording head filled with ink is left for a long period of time, the wetting agent solidifies in the recording head or the ink thickens significantly, so there is recovery by blowing and wiping the recording head. Operation, the problem that the ejection state of ink droplets cannot be restored to the state before placement

no. 1 approach

[0017] The first embodiment relates to an ink for an inkjet recording device. The ink for an inkjet recording device is an ink for an inkjet recording device containing at least water, a pigment, a high penetrating agent, a penetrating agent, and a humectant. The high penetrating agent includes 8-substituted 1,3-hexanediol or alkyl-substituted 1,3-pentanediol, penetrants include C1~C4 monoalkyl ethers of polyols, C6~C8 monoalkyl ethers of polyols or The content of polyol dibutyl ether, high penetrant, and the total amount of high penetrant and penetrant are in a specific range, and the humectant includes specific amounts of glycerol and 1,3-propanediol.

[0018] The ink for an inkjet recording device according to the first embodiment (hereinafter, may be simply referred to as ink) may contain a dissolution stabilizer for stabilizing the dissolved state of components contained in the ink as needed. Hereinafter, water, pigment, high penetrating agent, penetrating agent, humectan...

[0052] The second embodiment relates to an image forming method for forming an image with the inkjet recording device using the ink for the inkjet recording device of the first embodiment. The recording method of the inkjet recording device used in the image forming method according to the second embodiment is not particularly limited, and may be a continuous type in which recording is performed while scanning the recording head on the recording medium, or may be a recording method fixed to the main body of the device. A line header type for recording. The inkjet recording device used in the image forming method according to the second embodiment is preferably a recording device provided with a line head-type recording head from the viewpoint of high-speed image formation, and more preferably provided with an inkjet recording device provided on a side opposite to the conveyance of the recording medium. A recording device with a long line head in the direction perpendicular to ...

Abstract

The invention provides ink for inkjet recording apparatus suitable for high-speed image formation. Water and a pigment, as well as a high penetrating agent, a penetrating agent and a moisturizing agent each having specific kind and amount are incorporated in an ink for an inkjet recording apparatus. The high penetrating agent is an alkyl-substituted 1,3-hexanediol or an alkyl-substituted 1,3-pentanediol each having 8 carbon atoms. The penetrating agent is a C1-C4 monoalkyl ether of a polyhydric alcohol, a C6-C8 monoalkyl ether of a polyhydric alcohol, or a polyhydric alcohol dibutyl ether. The moisturizing agent is glycerin and 1,3-propanediol.

Description

technical field [0001] The present invention relates to an ink for an inkjet recording device and an image forming method using the ink for an inkjet recording device. Background technique [0002] In recent years, with the rapid development of recording technology, high-definition image quality comparable to that of silver halide photographs can be obtained, so inkjet recording devices that form images by inkjet recording methods are widely used as image forming devices. [0003] For the above-mentioned inkjet recording apparatus, an increase in image forming speed is strongly demanded. However, when image formation is performed at high speed in an inkjet recording device, before the ink penetrates into the recording medium such as paper, the recording medium carrying the ink is discharged through the discharge roller, and the ink may adhere (offset) to the discharge surface. roll. In this case, image defects tend to occur during image formation. In order to suppress the...
