Abstract
Provided are a monomer which can provide a cured product having both high toughness and rigidity, a monomer composition containing the monomer, the monomer composition used as a dental material monomer composition, a dental material composition containing the monomer composition or the dental material monomer composition, a cured product thereof having excellent mechanical properties, a dental material formed by curing the dental material composition, a method for producing the monomer composition, and a method for producing the dental material. A (meth)acrylate (D) is a reaction product of an amine compound (A) having two or more amino groups, an iso(thio)cyanate compound (B) having two or more iso(thio)cyanato groups, and a hydroxy (meth)acrylate compound (C) having one or more polymerizable groups.
