PROBLEM TO BE SOLVED: To prevent rising and peeling and to eliminate paste remaining phenomenon by using one main face of a transparent substrate as a recording side and the other main face as a reproduction light incidence side and disposing a protective film on the other main face by way of an acrylic adhesive layer in a peelable state. SOLUTION: A coloring material layer 3, a reflecting layer 4 comprising a metallic film of gold, silver, aluminum or the like and a protective layer 5 are successively laminated on one main face of a transparent substrate 1 comprising a polycarbonate resin or the like. A peelable protective film 6 is disposed on other main face by way of an acrylic adhesive layer. A gas permeable PP film as the protective film 6 is entirely coated with an acrylic adhesive comprising a crosslinked acrylic acid copolymer by means of a reverse coater so as to form the acrylic adhesive layer of a prescribed thickness. A margin to grasp is preferably provided to the protective film or handling items are preferably recorded on the surface of the protective film. |
