Ultraviolet-curable composition, method for producing cured object, cured object, ultraviolet-curable ink, method for producing printed matter, and printed matter

Abstract

Provided is an ultraviolet-curable composition which includes at least a radical-polymerizable compound, a polymerization initiator, and one or more solvents, wherein the radical-polymerizable compound is present as particles and the polymerization initiator includes a compound having a structure represented by formula (1) and a structure represented by formula (2). When the ultraviolet-curable composition which contains no colorant component is diluted 100 times the total mass of the ultraviolet-curable composition with a solvent which is the highest in mass proportion of the solvents, then the dilution has an absorbance at 385-nm wavelength of 0.40 or greater.
