<p>According to the method of making a magnetic coating material, 100 parts by weight of a magnetic metal powder, 1 to 10 parts by weight of fatty acid, 1 to 5 parts by weight of a dispersing agent, and a solvent are combined in the absence of a binding agent, wherein the solvent is present in sufficient amount to yield an admixture having a solids concentration of the magnetic metal powder in the range from 65 to 70 percent. The admixture is kneaded using a pressure kneader. The kneaded admixture is then blended with a binding agent to provide the magnetic coating material. <IMAGE></p> |
