Abstract

A compound (A) is represented by the formula (1):

wherein R 1 is a hydrogen atom or an alkali metal atom, R 2 is a hydrogen atom or an alkali metal atom, R 3 is a hydrogen atom or a methyl group, Z is a divalent or trivalent organic group, and the lines consisting of a solid line and a broken line bonded to Z represent a single bond or a double bond.

First claim

The invention claimed is:

1. A compound (A) represented by the formula (1):

wherein
R 1 is a hydrogen atom or an alkali metal atom,
R 2 is a hydrogen atom or an alkali metal atom,
R 3 is a hydrogen atom or a methyl group,
Z is a divalent or trivalent organic group, and the lines consisting of a solid line and a broken line bonded to Z represent a single bond or a double bond,
provided that when R 1 and R 2 are a hydrogen atom, and R 3 is a methyl group, Z is not a trivalent organic group including 1,4-phenylene group,
the compound (A) is not a compound represented by following formula:

the divalent or trivalent organic group Z in the formula (1) includes one or more groups selected from divalent groups represented by formula (Z1), ether bonds, 1,4-phenylene groups, 1,4-cyclohexylene groups and divalent linear saturated hydrocarbon groups,

wherein Y 1 and Y 2 are each independently an oxygen atom, a divalent group represented by —CH 2 — or a divalent group represented by —NH—, and Y 3 is an oxygen atom or a sulfur atom.

2. The compound (A) according to claim 1 , wherein the molecular weight is 200 to 600.

3. The compound (A) according to claim 1 , wherein the topological polar surface area (tPSA) is not less than 50.00 Å 2 .

4. The compound (A) according to claim 3 , wherein the C log P value is not less than −5.000.

5. The compound (A) according to claim 1 , wherein the divalent or trivalent organic group Z in the formula (1) is a C6-C20 linear saturated hydrocarbon group or a C6-C20 group having —O—C(═O)—CH 2 —.

6. A cured product obtained by curing an adhesive composition comprising a compound (A) represented by the formula (1) to a metal including a noble metal, a tooth substance or a ceramic:

wherein R 1 is a hydrogen atom or an alkali metal atom,
R 2 is a hydrogen atom or an alkali metal atom,
R 3 is a hydrogen atom or a methyl group,
Z is a divalent or trivalent organic group, and the lines consisting of a solid line and a broken line bonded to Z represent a single bond or a double bond.

7. The compound (A) according to claim 1 , wherein —C(═O)O— in the formula (1) is bonded to a CH 2 group in Z.

8. The compound (A) according to claim 1 , wherein the divalent or trivalent organic group Z in the formula (1) includes one or more groups selected from divalent groups represented by formula (Z1), ether bonds, 1,4-cyclohexylene groups and divalent linear saturated hydrocarbon groups.
