WIPO Patent Application WO/2016/199611

A1

The purpose of the present invention is to provide: an active light-curable inkjet ink set for three-dimensional printing, which has excellent formability, concealability and mechanical properties, and which enables the achievement of a full-color three-dimensional model; and a three-dimensional printing method. An active light-curable inkjet ink set for three-dimensional printing according to the present invention is characterized by containing a white ink composition W and a color ink composition C. White ink composition W: a composition which contains a white pigment and a polymerizable compound, and wherein the content of the white pigment relative to the total mass of the white ink composition W is from 0.5% by mass to 10% by mass. Color ink composition C: a composition which contains a coloring agent, a specific acrylate monomer AC and a specific acrylate monomer BC, and wherein the content of the acrylate monomer AC relative to the total mass of the color ink composition C is 5% by mass or more but less than 50% by mass and the content of the acrylate monomer BC relative to the total mass of the color ink composition C is 20% by mass or more but less than 80% by mass.
