Abstract

See full text

A method of making a multi-layered film includes depositing thin film layers onto a first side of a double-sided transparent substrate. The thin film layers are transparent, and two adjacent layers of said plurality of thin film layers have different refractive indices. One or more absorbers are deposited at an interface formed between two of the thin film layers that are adjacent to one another, or formed by the first side of the substrate and one of the thin film layers. The absorbers absorb selected wavelengths of incident light and reflect part of the incident light after inducing a phase shift. The location of the interface is selected to provide desired wavelengths of absorbed and reflected light. The multi-layered film has a first appearance when viewed from the first side of the substrate and a second appearance when viewed from the second side of the substrate.
