Description

This disclosure generally relates to articles such as optical tools in the form of foils, sheets, and/or flakes. The optical tools may include a reflective layer; a selective optical modulation layer outside the reflective layer; and functional molecules present in at least one of the following: the selective optical modulation layer, a functional layer outside the surface of the selective optical modulation layer, near the outer surface of the selective optical modulation layer, near the reflective layer of the selective optical modulation layer, and the functional layer outside the reflective layer. In another embodiment, the optical tools may include a reflective layer; a selective optical modulation layer outside the reflective layer; and functional molecules present in at least one of the following: the reflective layer, a functional layer outside the surface of the reflective layer, near the outer surface of the reflective layer, and near the selective optical modulation layer of the reflective layer. Methods for manufacturing optical tools are also disclosed. Pigment flakes in paint systems must be compatible with the specific chemical properties of the paint system. If the pigment flake material is not compatible with the paint system, the intended optical effect cannot be achieved due to the incorrect orientation of the pigment flakes in the paint. In certain applications, random flake orientation is required. To control the behavior of the flakes in the paint, it is necessary to control the surface energy of the flakes, in addition to adjusting the hydrophobicity or hydrophilicity as needed. Conventional pigment flake compatibility requires a separate chemical coating step in a chemical bath, for example, for the application of silane functionalization for compatibility with the desired paint chemistry. The material properties of vacuum-deposited pigment flakes cannot be gradually adjusted because all materials must be evaporated under vacuum, which significantly limits the choice of materials. Functionality can only be added in a separate chemical coating step to vacuum-prepared pigment flakes, and cannot be added as part of a layer coating process. In one embodiment, an optical tool is disclosed comprising a reflective layer; a selective optical modulation layer outside the reflective layer; and a functional molecule present in at least one of the selective optical modulation layer, a functional layer outside the surface of the selective optical modulation layer, near the outer surface of the selective optical modulation layer, near the reflective layer of the selective optical modulation layer, and the functional layer outside the reflective layer.

In further embodiments, optical tools are disclosed that include a reflective layer; a selective optical modulation layer outside the reflective layer; and a functional molecule present in at least one of the following: the reflective layer, a functional layer outside the surface of the reflective layer, near the outer surface of the reflective layer, and near the selective optical modulation layer of the reflective layer.
