ACTIVE RAY-CURABLE INKJET INK COMPOSITION, ACTIVE RAY-CURABLE INKJET INK SET, AND IMAGE FORMATION METHOD AND INKJET PRINTER EACH USING THE INK SET

摘要

PROBLEM TO BE SOLVED: To obtain an active ray-curable inkjet ink composition excellent in curability, free from occurrence of color mixing, and capable of stably printing highly fine images, to provide an active ray-curable inkjet ink set, and to provide an image formation method and an inkjet printer each using the ink set.

SOLUTION: The active ray-curable inkjet ink composition essentially comprises photopolymerizable compounds, an acid generator and a coloring material, wherein at least one of the photopolymerizable compounds is a cationically polymerizable monomer. This composition also contains 0.1-10 mass% of a 1-10C monohydric alcohol.
