| 摘要 |
The invention relates to a thin-layer element (30) having a multilayered structure for security papers, documents of value and the like, which appears to have a golden colour when viewed in incident light and which has at least two semitransparent mirror layers (34, 35) and at least one dielectric spacer layer (36) arranged between the at least two mirror layers, so that when measuring the transmission of un-polarised light in the blue wavelength range from 420 nm to 490 nm, a resonance having a half-value width of 70 to 150 nm is exhibited. |
