Method for applying formulations which contain bacteriorhodopsin onto substrates, and products produced by this method

摘要

The invention relates to a method for producing a coating, in regions, on a substrate, said coating being based on a formulation, in the form of an active color-change motif, which contains bacteriorhodopsin color-changing pigment, and to coatings produced using a method of this type and to articles having coatings of this type. Here, the method comprises the following steps: a) printing of the substrate with the formulation, in the form of a motif, containing bacteriorhodopsin color-changing pigment; b) partial drying of the printed substrate; c) optionally repetition of steps a) and/or b); calendering of the printed and partially dried substrate; e) complete drying of the coating.

1. A method for producing a coating, in regions, on a substrate, said coating being applied in the form of an active colour-change motif, said coating being based on a formulation that contains bacteriorhodopsin colour-change pigment, said method comprising the following steps:
a) printing of the substrate with the formulation, which contains bacteriorhodopsin colour-change pigment, in the form of a motif; b) partial drying of the printed substrate such that the coating is no longer sticky, but still soft and compressible; c) optionally repeating steps a), b), or both a) and b); d) calendering of the printed and partially dried substrate; e) complete drying of the coating.
