Inkjet ink composition for increasing drying speed of ink on surface of paper sheet

Abstract

The invention relates to an inkjet ink composition for increasing drying speed of ink on the surface of a paper sheet. The ink composition comprises (1) alcohol containing a carbon-carbon triple bond and (2) alkyl diphenyl ether disulfonate. Experiment results show that the ink composition provided by the invention increases the drying speed of the ink on the surface of the paper sheet while guaranteeing the jet quality so as to adapt to high-speed printing.

Description

technical field [0001] The present invention relates to ink compositions for use in ink jet printer ink formulations. Background technique [0002] Inkjet printing is a method of printing in a non-contact way. After nearly 30 years of development, its printing speed and printing quality are close to or reach the traditional printing methods of offset printing and other contact methods. Laid the technical foundation. However, the high-speed digital printing method also puts forward new and higher requirements for inkjet inks: [0003] (1) Inkjet ink should meet the requirements of high-frequency jetting of inkjet printer nozzles, and the jetting frequency is about 30KHZ. [0004] (2) Inkjet ink should ensure stable performance and short maintenance time during long-term (several days) high-intensity work. [0005] (3) The inkjet ink should have a high drying speed on the surface of the paper to ensure that it will not pollute other paper during fast winding (printing and w...

AI Technical Summary

Problems solved by technology

However, by increasing the contact angle of the ink on the nozzle surface, not only will the manufacturing cost of the nozzle be increased, but also as the nozzle works for a long time, the coating on the nozzle surface will partially fall off, causing the problem of jetting failure.
