CURABLE COMPOSITION, THREE-DIMENSIONAL OBJECT PRODUCING METHOD, THREE-DIMENSIONAL OBJECT PRODUCING APPARATUS, AND ARTIFICIAL TOOTH OBJECT

Document Type and Number:

Japanese Patent JP2023140203

Kind Code:

A

Abstract:

To provide a curable composition that is free of titanium oxide and highly safe, is suitable for inkjet ejection, and exhibits high strength and whiteness after curing.SOLUTION: A curable composition contains 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. The content of the hard solid component is 3 vol.% or greater and 40 vol.% 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.SELECTED DRAWING: None
