The present invention provides an adhesive composition comprising a polymerizable phosphonic acid derivative which is a composition having intramolecularly a polymerizable group and a phosphonic acid group, represented by the general formula [1]:
wherein
R represents a polymerizable group;
A represents an oxygen atom or a sulfur atom;
X
q
s represent independently an oxygen atom or a sulfur atom;
Y
q
s represent independently the same or different organic group;
Z
q
s may be independently the same or different from each other and, a part of the Z
q
s optionally selected or all of the Z
q
s represent organic groups having a substituent which is an organic group other than a polymerizable group and a phosphonic acid group;
p is an integer from 1 to 10;
q is an integer from 1 to p;
when p is 1,
q is 1;
X
1
represents an oxygen atom or a sulfur atom;
Y
1
represents an organic group;
Z
1
represents an organic group having one or more of substituents which are organic groups other than an acidic group and a polymerizable group, or a salt thereof. The adhesive composition or the salt thereof according to the present invention improve a shelf life and adhesion properties of an adhesive composition comprising essentially a (meth)acrylate monomer having intramolecularly an acidic group and water in dental treatment.
