A dental adhesive material kit may have desirable adhesive properties for tooth structure, and, while ensuring appropriate strength, may allow easy removal of excess cement in a semi-cured state created by temporarily applying light to excess portions of cement with a photoirradiator. Such a dental adhesive material kit may include a dental aqueous adhesive composition (A) and a dental curable composition (B), satisfying the inequality (I)
0t2t13.0(I),
wherein t1 (min) is a contactual polymerization start time of the dental aqueous adhesive composition (A) and the dental curable composition (B), and t2 (min) is a polymerization start time of the dental curable composition (B).

The invention relates to an aqueous dental single-component primer composition as well as a kit with this primer composition and a composite. The primer composition according to the present invention is self-etching and self-undercoating. It comprises a polymerizable (meth)acrylate or (meth)acrylamide monomer with (i) at least one acidic group such as for example a phosphoric acid group and with (ii) at least one hydrophilic group such as for example a terminal hydroxy group or two polymerizable (meth)acrylate or (meth)acrylamide monomers, wherein one thereof comprises (i) at least one acidic group and one thereof comprises (ii) at least one hydrophilic group. In addition, at least one of the polymerizable (meth)acrylate or methylacrylamide monomers comprises (i) a polyfunctionality, preferably an at least threefold polyfunctionality, particularly preferably a 3-, 4-, 5-, 6-, 7-, 8-, 9- or 10-fold polyfunctionality and/or (ii), or a further polymerizable (meth)acrylate or methylacrylamide monomer (iii) with a polyfunctionality, preferably an at least three-fold polyfunctionality, particularly preferably a 3-, 4-, 5-, 6-, 7-, 8-, 9- or 10-fold polyfunctionality is contained. This polyfunctionality inheres in the capability to polymerize. In particularly, at least three, preferably terminal, (meth)acrylate, (meth)acrylamide and/or allyl groups are present. Furthermore, this primer composition is characterized by the absence of a photoinitiator, a polymerization catalyst, in particularly a polymerization catalyst on the basis of vanadium as well as by the absence of an organic solvent.
