Abstract: A double-sided, holographic replica comprises a web of transparent, thermoplastic, sheet material having a separate series of off-axis-recorded, phase-modulated holograms pressed into each of the opposite surfaces, respectively, of the web. Oppositely disposed (front and rear) holograms are such as to provide angularly displaced reconstructed images, respectively, when a monochromatic read-out beam is transmitted through the web. The double-sided holographic replica is made by first pressing the web and a first holographic master between a first pair of heated calender rollers to form one replica on one surface of the web, and then pressing the web, while thermoplastically adhered to the first master, and a second holographic master between a second pair of heated calender rollers to form another replica on the other surface of the web. The first and second masters are subsequently cooled and separated from the web.

Abstract: A holographic replica in the form of a tape comprises a thermoplastic vinyl polymeric sheet having holographic information in the form of a relief pattern embossed on a surface thereof. The polymeric sheet generally has a thickness of 1 to 6 mils. and the embossed information generally has a contour depth of about up to 500A. The process for making the holographic replicas comprises embossing a pattern consisting of peaks and valleys from either an original holographic image or a holograph master onto a thermoplastic polymeric sheet at a temperature substantially below the flow temperature of the thermoplastic sheet and with a pressure of less than about 200 psi.
