Security device with printed metal layer in the form of a pattern and method of manufacturing the same |
| abstract |
A security device with improved visibility using a printed metal layer. A transparent base layer having a surface provided with an optically variable relief microstructure, a transparent high refractive index layer adapted to the surface relief microstructure on the surface of the base layer, and transparent high refraction. A reflective metal layer 20 printed on the refractive index layer, wherein the reflective metal layer is printed in the form of a pattern, and the thickness of the transparent high refractive index layer is reflected on each surface of the transparent high refractive index layer 450 The metal layer is chosen to be λ / 2n, where n is the refractive index of the transparent high refractive index layer, so as to achieve constructive interference of light at a wavelength λ in the range of ˜650 nm. A security device formed by metal particles, such as small pieces or platelets, wherein the metal particles are adapted to the surface relief microstructure. [Selection] Figure 1A |
