Abstract
Provided is an active-energy-ray-curable composition including: a polymerizable monomer having static surface tension of 40 mN/m or greater at 25 degrees C., a content of the polymerizable monomer being 15% by mass or less relative to total amount of the active-energy-ray-curable composition; an organic pigment serving as a colorant, the organic pigment being contained in 2% by mass or greater relative to total amount of the active-energy-ray-curable composition; and a dispersant having amine value of 5 mgKOH/g or greater but 35 mgKOH/g or less, amine value being greater than acid value of the dispersant, the dispersant being contained in 15% by mass or greater but 70% by mass or less relative to mass of the organic pigment, wherein the active-energy-ray-curable composition is substantially free of a surfactant, and wherein a water content in the active-energy-ray-curable composition is 500 ppm by mass or greater but 3,000 ppm by mass or less.
