Title: ADHESIVE MONOMER FOR DENTAL MATERIAL
Abstract:
The purpose of the present invention is to provide an adhesive monomer for a dental material, having a function of improving adhesion strength to tooth structures during dental therapy, and to provide an adhesive monomer for a dental material which imparts high mechanical strength to a cured product. An adhesive monomer for a dental material is provided which contains a compound represented in general formula (1), which comprises a core part (X) and a terminal group (Y1) bonded together directly or with a linking group (Z) interposed therebetween. (1) X(Y1)n1a(Z-Y1)n1b (in general formula (1) above, n1a represents the number of terminal groups (Y1) directly bonded to the core part (X), n1b represents the number of terminal groups (Y1) bonded to the core part (X) with a linking group (Z) interposed therebetween, and the sum of n1a and n1b is equal to the valence of the core part (X); the core part (X) contains an oxygen atom or a nitrogen atom, and is a polyvalent organic group of 1-200 carbons having a valence of 3 or more, in which the atom bonding to the terminal group (Y1) or the linking group (Z) is an oxygen atom or nitrogen atom; the terminal group (Y1) is a specific phosphorus-containing group, a specific (meth)acryloyl group-containing group (Y2), a (meth)acryloyl group, a hydrocarbon group with 1-20 carbons, or a hydrogen atom; multiple terminal groups (Y1) may be the same or different, however, one or more of all the terminal groups (Y1) in the compound represented by general formula (1) are a specific phosphorous-containing group, and one or more is a (meth)acryloyl group-containing group (Y2); the linking group (Z) is a specific divalent group, and if multiple linking groups (Z) are included, then the linking groups (Z) may be the same or different.)
