RETRO-EFFECTIVE FOLLOWS AND PROCEDURES FOR THEIR ESTABLISHMENT

摘要

Retro-reflecting film, having:a first protective film (25);a first thermoplastic binding medium (23) trained on the first protective film (25);a first non-flammable binding medium (21) which is formed on the first thermoplastic binding medium (23);a coloured layer (19) formed on the first non-flammable binding medium (21);a light-permeable layer (17) formed on the coloured layer (19);a coloured area (L1),which has a first layer of light collection (15), which is formed on the translucent layer (17) and which passes through the translucent layer (17) light which is passed through the first layer of light collection (15), and which sprinkles the light supplied on an interface with the coloured layer (19),so that a proportion of the scattered light is emitted outwards through the first layer of light collection (15) together with fluorescent light or light accumulated in the coloured layer (19);a second protective film (39);a second thermoplastic binding medium (37) which is formed on the second protective film (39);a second non-flammable binding medium (35) formed on the second thermoplastic binding medium (37) so that it has a thickness corresponding to the sum of the thickness of the first non-flammable binding medium (21) and the coloured layer (19);a reflective layer (33) formed on the second non-flammable binding medium (35);a reflecting area (L2), which has a second light collection layer (31), is formed on the reflecting layer (33), so that the reflecting layer (33) reflects light which is supplied to the reflecting layer (33) by the second light collection layer (31);anda base film (41) glued to the first layer of light collection (15) and the second layer of light collection (31) by a bead binding layer (43).
