PURPOSE: A polymer film for copying a hologram program is provided to facilitate the embossing of hologram image by forming a hologram receiver layer. CONSTITUTION: An amorphous sheet of one-axis or two-axis orientation polymer base layer is made of one selected from a group including polyester, cellulose triacetate, polyimide, polycarbonate and polysulphone. Methylacrylate 15 weight part and ethylacrylate 85 weight part are copolymerized to obtain an acryl emulsion resin with a glass transition temperature of 25deg.C. The acryl emulsion resin 2 to 4wt% is dispersed into water to obtain a distribution solution with a viscosity of at most 6cps. The distribution solution is coated on at least one surface of the amorphous sheet with a thickness of 0.1 to 1.0 micrometers. The amorphous sheet is one-axis or two-axis elongated. |
