Abstract: To provide a composite for a dental pattern resin whose shrinkage when curing and expansion when heated can be both suppressed as its usability is kept, the composite for a dental pattern resin includes a liquid formulation and a powder formulation, wherein the liquid formulation includes a polymerizable monofunctional (meth)acrylate, a polymerizable polyfunctional (meth)acrylate, and a polymerization accelerator, and the powder formulation includes more than 5 mass % of a (meth)acrylate copolymer on the basis of the total powder formulation.
