INK COMPOSITION FOR WATER-BASED INKJET

摘要

PROBLEM TO BE SOLVED: To provide an ink composition for water-based inkjet having superior time stability and jettability of the ink and gloss and brightness of the printed matter.

SOLUTION: The ink composition for water-based inkjet contains a fine particle resin dispersion obtained by radically polymerizing an ethylenic unsaturated monomer in an aqueous medium in the presence of water-soluble resin (A). Use of the fine particle resin dispersion in the ink composition for water-based inkjet improves time stability of the ink and clogging of the ink in jetting. The fact that a fine particle resin dispersion having a smaller average particle size is easily obtained and the ink composition has a good film formation produces printed matter having superior gloss and brightness.
