NONIONIC ADDITIVE FOR CONTROLLING PUDDLING OF INKJET INK

摘要

PROBLEM TO BE SOLVED: To provide inkjet ink improved in puddling at a print head and a method for decreasing the puddling of inkjet ink.

SOLUTION: A puddling additive comprising a nonionic polar group and a 6-30C hydrocarbon chain line is used to improve the puddling of inkjet ink. The nonionic polar group is an alcohol group, an alkene group, or a zwitterionic group, and the 6-30C hydrocarbon chain line is a saturated or unsaturated 6-30C hydrocarbon chain. The inkjet ink further contains a dye and an inkjet vehicle. The method for reducing the puddling of inkjet ink includes the addition of the puddling additive to the inkjet ink.
