Färgskiftpigment

Färgskiftpigment, also known as iridescent or pearlescent pigments, are special effect pigments that change color depending on the angle of light and observation. This phenomenon is achieved through a multilayered structure, typically composed of thin, transparent layers of metal oxides coated onto a substrate, often mica. The interference of light waves reflecting off these different layers creates the illusion of shifting colors.

The specific colors observed are determined by the thickness of the oxide layers and the materials used. Common substrates include natural mica, synthetic mica (fluorphlogopite), and glass flakes, each offering different levels of brilliance and particle size. Titanium dioxide and iron oxides are frequently used as the coating materials due to their refractive properties and color possibilities.

Färgskiftpigment find widespread application in various industries. In automotive coatings, they provide a dynamic and eye-catching finish. They are also used in cosmetics, such as eyeshadows, nail polishes, and lipsticks, to create shimmering and multi-dimensional effects. The printing industry utilizes these pigments for security features on banknotes and documents, as well as for decorative printing on packaging and textiles. The unique visual properties of färgskiftpigment make them a popular choice for applications where visual appeal and a sense of depth are desired.
