<p>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 colour-change motif, which contains bacteriorhodopsin colour-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 colour-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.</p> |
