    • 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.
    • 反射膜(5)在一侧具有一层微球(2),并且在两个压印滚筒(6)之间被热成型。 压花圆筒(6)周边地表现出两个矩阵,它们在承载微球的薄膜(5)一侧产生微观浮雕的分布,并在相对的侧面上产生相应的空腔。 将材料的基层(4)施加到具有空腔的一侧,填充它们。 热成型膜包括插入在微球体(2)之间的透明树脂的第一层(31)和含有金属的薄反射层(32),所述薄层反射层又被保护材料的多个层(33和34)覆盖 耦合到可热成型材料的层(35)。 反射层板有效地应用于水平道路信号领域。
