<p>A clay dispersion, wherein an organically modified clay is dispersed in a polar organic solvent, and the clay dispersion is obtained by: dispersing a swelling clay in a liquid which includes water as a main component; adding organic onium ions to the liquid to cause ion-exchange between the organic onium ions and hydrophilic cations existing on the surface of the swelling clay to obtain an organically modified clay; removing the ion-exchanged hydrophilic cation to obtain the organically modified clay which is in a condition that water exists in the clay; and adding the organically modified clay from which the ion-exchanged hydrophilic cation is removed to an polar organic solvent.</p> |
