Abstract
A method of transferring a high resolution polarizing image from a mass transfer donor element to a receptor element. The transfer can be induced by thermal energy or electromagnetic (optical) energy. In either case, the transferred image will be a high resolution image that exhibits optically anisotropic properties. The polarizing mass transfer donor element comprises a substrate having a polarizing mass transfer layer coated thereon. Optionally, the polarizing mass transfer donor element further comprises a light absorbing material, preferably in the form of a light to heat conversion layer. The polarizing mass transfer donor element can further comprise an adhesive to facilitate transfer of the polarizing mass transfer layer.
