Abstract

Electromagnetically controllable microbodies whose optical properties may be altered by changing their orientations are useful in imaging and display devices, The microbodies may be microspheres with one hemisphere white, one black, and either being magnetic, Such microbodies may be coated in a con-trolled manner by applying a monolayer thereof on a plastic or polymeric sheet, The sheet and microbodies are exposed to solvent vapor which softens the sheet and the microbodies are allowed to imbed in the sheet to a desired depth- Solvent vapor is removed and metallization, demetallization, color-ization or decolorization is conducted on the sheet-micro-bodies composite. The microbodies are then dislodged from the sheet with additional solvent and collected,
