Abstract

The present invention provides a self-adhesive composite resin having excellent adhesiveness to tooth structures and excellent mechanical strength. The present invention relates to a self-adhesive dental composite resin containing: an asymmetric acrylamide-methacrylic acid ester compound (a); an acid group-containing (meth)acrylic polymerizable monomer (b); a hydrophobic crosslinkable polymerizable monomer (c); a photopolymerization initiator (d); and a filler (e). The asymmetric acrylamide-methacrylic acid ester compound (a) is represented by the following general formula (1):where X is an optionally substituted, linear or branched C1 to C6 aliphatic group or an optionally substituted aromatic group, the aliphatic group is optionally interrupted by at least one linking group selected from the group consisting of —O—, —S—, —CO—, —CO—O—, —O—CO—, —NR1—, —CO—NR1—, —NR1—CO—, —CO—O—NR1—, —O—CO—NR1—, and —NR1—CO—NR1—, and R1 is a hydrogen atom or an optionally substituted, linear or branched C1 to C6 aliphatic group.
