Assignee: RICOH COMPANY, LTD.
Field: Other special machines (Mechanical engineering)
Classification: CPC C  B | IPC B  C

Claim 0:
1. An active-energy-ray-curable composition comprising:
a polymerizable monomer having static surface tension of 40 mN/ni or greater at 25 degrees C., a content of the polymerizable monomer being 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 has a surfactant content of less than 0.1% by mass or is free of a surfactant,
wherein the active-energy-ray-curable composition is free of a radical-polymerizable 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.
