ADJUSTMENT OF THE PROPERTIES OF A RETINAL PROTEIN IN A PHOTOCHROMIC PRODUCT

摘要

A product having a substrate and a color application applied thereto is specified. The color application comprises, in each of a first area element and a second area element, at least one color layer (32) comprising a retinal protein which shows a color change when illuminated. Present in at least one of the area elements is a functional layer (33, 33′) which alters the proton availability for the retinal protein in the area element in question, such that the color change of the retinal protein in the first area element and in the second area element shows a different time dependence and/or light sensitivity.

1. A product, comprising:
a substrate; and a color application applied thereon, wherein the color application in each of a first and a second surface element has at least one color layer comprising a retinal protein which exhibits a color change on illumination, wherein in at least one of the surface elements at least one functional layer is present which alters the proton availability for the retinal protein in the surface element concerned, so that the color change of the retinal protein in the first and in the second surface element exhibits at least one of a different time dependence and/or light sensitivity.
