Coating comprising a photochromic material, a method for its production as well as its use

摘要

The invention relates to a coating comprising a photochromic material, its production and its use. The photochromic material of the coating has an optically reversible photochromic effect, wherein the switching threshold is disposed outside of or in the boundary region of the visible range of the spectrum. According to the invention, the photochromic material is coated with an influencing material, so that the switching threshold of the coated photochromic material is shifted towards wavelengths longer than the switching threshold of the uncoated photochromic material.
