Abstract
An adhesive agent comprising a condensation resin having a structural unit obtained by polycondensing a polymerizable monomer containing a monomer (A) having 2 or more carboxyl groups and a monomer (B) having 2 or more amino groups, and meeting at least one of the following (1) and (2), and the following (3): (1) at least one selected from the group consisting of the monomer (A), an anhydride of the monomer (A), and the monomer (B) is liquid at 25° C.; (2) the condensation resin has a polyoxyalkanediyl group; and (3) the condensation resin has a cyclohexane ring.

An adhesive agent comprising a polyamide resin having a structural unit obtained by polycondensing a polymerizable monomer containing a monomer (A) having 2 or more carboxyl groups and a monomer (B) having 2 or more amino groups, the polyamide resin contains an isophthalic acid unit, and meeting at least one of the following (1) and (2)
- (1) at least one selected from the group consisting of the monomer (A), an anhydride of the monomer (A), and the monomer (B) is liquid at 25° C.;
- (2) the polyamide resin has a polyoxyalkanediyl group;
- and
- wherein the polyamide resin contains a diamine unit having a cyclohexane ring;
- wherein the content of the diamine unit having a cyclohexane ring in the polyamide resin is 0.1 to 20 mol % based on the total amount of the monomer (A) unit and the monomer (B) unit, and
- wherein the content of the isophthalic acid unit in the polyamide resin is 87.5-100 mol %, based on the total amount of the isophthalic acid unit and a terephthalic acid unit.
