A reflective film (5) has a layer of microspheres (2) on one side and is heat-formed between two embossing cylinders (6). The embossing cylinders (6) peripherally exhibit two matrices which produce, on the side of the film (5) bearing the microspheres, a distribution of microscopic reliefs, and on the opposite side, corresponding cavities. A base layer (4) of material is applied to the side with the cavities, filling them. The heat-formed film comprises a first layer (31) of a transparent resin interpositioned between the microspheres (2) and a thin reflecting layer (32) containing metal, which in turn is covered by several layers (33 and 34) of protective material coupled to a layer (35) of heat-formable material. The reflector laminate is usefully applied in the field of horizontal road signals. |
