<p>PROBLEM TO BE SOLVED: To manufacture a material which has a performance to make a played-back image clearly visible and is of a high quality free from an uneven defect on the surface, and further, is of a high mass-productivity. SOLUTION: A transparent resin film with a high light transmissivity of, at least, 80% and a total light reflection factor of not more than 7% is continuously stuck to one face of both faces of a transparent resin sheet. In this case, the transparent film is laminated on the transparent resin sheet at a tension rate of 1-10kg/m (per the length of a roll).</p> |
