Claim 19:
20. An active-energy-ray-curable composition comprising:
(meth)acryloyl morpholine as a polymerizable monomer having a static surface tension of 40 mN/m or greater at 25 degrees C., a content of the polyme,rizable monomer being 5% by mass or greater but 15% by mass or less relative to a 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 the total amount of the active-energy-ray-curable composition; and
a dispersant having an amine value of 5 mgKOH/g or greater but 35 mgKOH/g or less, the amine value being greater than an acid value of the dispersant, the dispersant being contained in 15% by mass or greater but 70% by mass or less relative to a mass of the organic pigment,
wherein the active-energy-ray-curable composition is free of a surfactant,
wherein the active-energy-ray-curable composition is free of a radical-poly erizable compound containing a vinyl ether group and a (meth)acrylate group, 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.
