Claim:
1. A dental color tone adjustment material kit, comprising a primer composition (A) and a dental color tone adjustment material (B), wherein the primer composition (A) comprises an acid group-containing polymerizable monomer (a) and a volatile organic solvent (b), the dental color tone adjustment material (B) comprises a polymerizable monomer (d), a polymerization initiator (e), particle aggregates (f), titanium dioxide (g), and a pigment (h), a content of the acid group-containing polymerizable monomer (a) is 0.05 to 45 weight % of a total weight of the primer composition (A), a content of the volatile organic solvent (b) is 55 to 99.95 weight % of a total weight of the primer composition (A), the polymerizable monomer (d) comprises a polyfunctional acrylate monomer (d1) having three or more acryloyl groups per molecule and a volatile monofunctional (meth)acrylate monomer (d2), a total content of the monomer (d1) and the monomer (d2) is 88 weight % or more of a weight of the polymerizable monomer (d), the particle aggregates (f) are chain aggregates of ultrafine filler particles having an average primary particle diameter of 1 to 50 nm, a content of the particle aggregates (f) is 5 to 20 parts by weight per 100 parts by weight of a total weight of the polymerizable monomer (d) and the particle aggregates (f), a content of the titanium dioxide (g) is 0.05 to 2 parts by weight per 100 parts by weight of a total weight of the polymerizable monomer (d) and the particle aggregates (f), and the pigment (h) is a pigment other than the titanium dioxide (g).
