Abstract

The invention discloses inkjet ink applicable to photo printing and a preparation method thereof. The inkjet ink is prepared from the following raw materials in percentage by weight: 20 to 40 percentof dyestuff color paste, 2 to 10 percent of a high-boiling-point solvent, 10 to 30 percent of a medium-boiling-point solvent, 1 to 5 percent of a low-boiling-point solvent, 0.2 to 3 percent of a surfactant, 0.1 to 0.2 percent of fungicide and 20 to 40 percent of de-ionized water, wherein the high-boiling-point solvent is a solvent with the boiling point which is greater than or equal to 250 DEG C;the medium-boiling-point solvent is a solvent with the boiling point which is greater than 120 DEG C and less than 250 DEG C; the low-boiling-point solvent is a solvent with the boiling point which is greater than 70 DEG C and less than or equal to 120 DEG C. With the adoption of the manner, the inkjet ink disclosed by the invention is matched with other raw materials by adopting a specific ratioand the solvents with different melting points; all the raw materials are cooperatively matched and the product ink can have good printing smoothness and does not block a spraying nozzle; the ink hasgood color representation on photo paper, does not have a color blending phenomenon and is applicable to the photo printing.

Description

technical field

[0001] The invention relates to the technical field of inkjet ink, in particular to an inkjet ink suitable for photo printing and a preparation method thereof. Background technique

[0002] With the widespread use of digital cameras, more and more digital camera users hope to output and retain the photo images taken by digital cameras on printing media. In order to meet the needs of such users, photo printers have emerged as the times require. With the popularization of digital cameras and the development of the imaging industry in recent years, various types of photo printers have been introduced and used, including inkjet photo printers, dye sublimation thermal transfer photo printers and direct heating photo printers. Among them, inkjet photo Printers are widely used. For inkjet photo printers, the performance of inkjet ink is an important factor affecting the printing effect of inkjet photo printers, while the existing conventional inkjet inks suitable f...
