PURPOSE: To bring uneven patterns into relief outstandingly in the visible direction without being lost to or hard to view by providing a metallized surface and translucent metallized layer on the uneven pattern surface of a transparent synthetic resin film having uneven patterns on its surface.
CONSTITUTION: There is employed as a base material a substance in which an isocyanate based anchor coat is given to a biaxially oriented polyester film. The anchor coat surface is subjected to a corona discharge treatment, and in use of T-die extrusion laminating machine, polyester resin is extruded at a temperature of 300°C and with a thickness of 30μm. At this time, along a cooling mirror roll, a polypropylene formed sheet having crushed stone patterns consisting of fine multi-way embossed stripes is disposed in a manner placing the pattern surface into contact with the extruded resin, and they are pressed by means of a press roll in a state of the extruded resin sandwiched therebetween.
