Title: ACTIVE RAY-CURABLE INKJET INK, AND IMAGE FORMATION METHOD USING SAME
Abstract:
The purpose of the present invention is to provide: an active ray-curable inkjet ink which has good dispersion stability during storage, good surface smoothness when ejected on a recording medium, and does not undergo the bleeding of a fatty acid onto the surface of the ink; and an image formation method using the active ray-curable inkjet ink. The purpose can be achieved by an active ray-curable inkjet ink which comprises: a photopolymerizable compound; at least one wax in the total mass of 1 to 8 mass% relative to the whole mass of the ink; and a fatty acid in the total mass of 0.0001 to 0.10 mass% relative to the whole mass of the wax.
