Abstract
A curable composition containing a radical-polymerizable monomer and a hard solid component having a volume average particle diameter of 10 nm or greater and 1,000 nm or less is provided. The content of the hard solid component is 3% by volume or greater and 40% by volume or less. The difference (n1−n2) between the refractive index (n1) of a cured product of any other component than the hard solid component and the refractive index (n2) of the hard solid component is 0.04 or greater.

A curable composition, comprising:
- a radical-polymerizable monomer;
- and
- a hard solid component having a volume average particle diameter of 10 nm or greater and 1,000 nm or less,
- wherein a content of the hard solid component is 3% by volume or greater and 40% by volume or less,
- an absolute value (|n1−n2|) of a difference between a refractive index (n1) of a cured product of any other component than the hard solid component and a refractive index (n2) of the hard solid component is 0.04 or greater, and
- a viscosity of the curable composition at 25° C. is 1,000 mPa·s or lower.
