Document Type and Number:
Japanese Patent JP2624443
Kind Code:
B2
Abstract:
PURPOSE: To provide a magnetic fluid material having low optical density in visible and near infrared wavelength ranges.
CONSTITUTION: An ion exchange resin is prepared, to which an ion capable of forming a magnetic phase is loaded. The resin is treated to form magnetic particles in situ. The above-mentioned ion exchange resin and magnetic particles are fluidized in an aq. medium, to form a stable colloid of magnetic particles.
