Abstract:
1. A one-package dental adhesive composition comprising: (A) a polymerizable monomer component containing not less than 5% by mass of an acidic group-containing polymerizable monomer; (B) a polyvalent metal ion-eluting filler; (C) a volatile organic solvent; (D) water; and (E) a photopolymerization initiator, wherein said polyvalent metal ion-eluting filler (B) is blended in such an amount that the amount of the polyvalent metal ions eluted out from said filler becomes 1.0 to 7.0 meq per gram of said polymerizable monomer component (A); said volatile organic solvent (C) is blended in an amount in a range of 60 to 100 parts by mass per 100 parts by mass of said polymerizable monomer component (A) satisfying a condition expressed by the following formula (1): wherein α is the amount of said volatile organic solvent (C) blended per 100 parts by mass of said polymerizable monomer component (A), X is a number representing the amount of the polyvalent metal ions eluted out from said polyvalent metal ion-eluting filler (B) or the amount (meq) thereof per gram of said polymerizable monomer component (A), and said water (D) is blended in an amount of 3 to 30 parts by mass per 100 parts by mass of said polymerizable monomer component (A), wherein the dental adhesive composition is not gelled after preservation for one month at 37° C.
