Abstract
A magnetic paint including magnetic powder, a binder and organic solvents is provided. The magnetic paint is prepared by first dispersing the magnetic powder and an amount of the binder in the range from about 20% to about 80% by weight based on the weight of the total binder in a poor solvent of the binder so as to obtain a first dispersion, dispersing after adding a good solvent of the binder and the rest of the binder into the first dispersion, and then dispersing the mixture so as to a second dispersion. About 25% by weight or more of the binder based on the weight of the total binder is adsorbed to the magnetic powder.
