Influence of Coalescent on the Gloss of Plastic Water-Based Flexographic Ink

摘要

This article analyzed and studied the effects of different types of coalescing agent on gloss of plastic water-based flexographic ink. As one of the most important characters for plastic water-based flexographic ink, gloss determines the quality of the flexo-printing products. It is significant for plastic water-based flexographic ink to improve the film quality and reduce the dosage of coalescing agent. We mainly studied on the influence of mass fraction of alcohol coalescing agent (A1), esters coalescing agent (A2) and esters coalescing agent (A3) in plastic water-based flexographic ink. The results indicated that the best dosages of the three kinds of coalescing agents are 1.4, 1.0 and 1.0%. The gloss is increasing 5.2, 14.6 and 10.3% respectively. The esters coalescing agent (A2) have notable effect on the gloss of the ink.
