  • Polarizing mass transfer donor element and method of transferring a polarizing mass transfer layer
    Patent number: 5693446
    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.

  • Polyurethanes and polyurethane/polyureas crosslinked using 2-glyceryl acrylate or 2-glyceryl methacrylate
    Patent number: 4786657
    Abstract: A crosslinkable polyurethane or polyurethane/polyurea comprises the reaction product of a composition comprising a macrodiol or macrodiamine, 2-gl;yceryl acrylate or 2-glyceryl methacrylate, a diisocyanate, and optionally a small glycol or small diamine as chain extender. The performance properties of the polyurethanes and polyurethane/polyureas can be controlled by adjustment of the crosslink level and/or curing parameters.
