Metallised film and process for its manufacture

A process for manufacture of a metallised film, comprising:

• providing at least one backing;
• applying at least one reflective layer extending facing said backing;
• printing a layer of metallised ink facing said baking in order to create at least one reflective layer;
• wherein
• in order to create said layer of printed metallised ink, a printing composition is used including a hardenable binder incorporating discrete solid metallised particles exhibiting a reflective metallic appearance and a grain-size distribution,
• a printing composition is used that includes, by way of metallised particles, metallised pigments or metallic particles in the general form of platelets exhibiting reflective faces, each metallised particle being in the general form of a platelet, and
• wherein said layer of printed metallised ink is printed in contact with a layer exhibiting a surface tension greater than 40 dynes/cm and a smooth surface quality and of specular reflection greater than 50, measured in accordance with standard ISO 2813 with an angle of 60°.
