ABSTRACT:
Optical membranes having embossed data on their surfaces are made by dispensing the polymer/solvent mixture onto a rotatable supporting surface bearing the embossed data, spinning the rotatable surface under conditions sufficient to form the membrane from the polymer and removing the membrane, after formation, from the rotatable surface. Such membranes can be light-transmissive, light-reflective or, as desired, partially reflective and partially transmissive.
