Patent number: 8409342Abstract: A pearlescent pigment and a process for enhancing the magnetic properties of a pearlescent pigment. The pearlescent pigment has a layer with regions of ?-Fe2O3 and regions of ?-Fe2O3. The magnetic properties of a pearlescent pigment may be enhanced by the steps of: providing a platelet pigment with a layer of Fe2O3, with a magnetic susceptibility less than 0.1×10?5 m3/kg; reducing some or all of the Fe2O3 to Fe3O4; and oxidizing some or all of the Fe3O4 to ?-Fe2O3. The color difference (?E*) between the provided pigment and the resultant pigment is not more than about 5.Type: GrantFiled: June 26, 2012Date of Patent: April 2, 2013Assignee: Sun Chemical CorporationInventors: Aaron M.
