Pigments Based on Holography and Gratings

The average distance between the peaks of the structure is about 800 nm. 

Holographic flake pigments are useful for the preparation of decorative coatings that can be used to emphasize the lines and contours of a three-dimensional surface. Another possibility is the application in molded plastics to provide a decorative appearance, e.g., in tiles.
