Abstract
A magnetic paint is prepared by a method comprising a surface-treating step for magnetic powder, to obtain a first composition by mixing and stirring a composition which comprises a magnetic powder, a dispersant and/or a binder resin, and an organic solvent, and which contains 40% by weight or less of a non-solvent component, while applying a shear force to the composition; and a concentrating step to obtain a second composition by concentrating the first composition until the content of the non-solvent components of the first composition reaches 80% by weight or more.
