Abstract: The present invention relates to a method for providing a substrate with a tint and a functional coloring, comprising the following steps (a) to (c) in this order: (a) providing a substrate to be provided with a tint and a functional coloring, the substrate being made of plastic glass and the substrate having a first main side and a second main side with a convex shape opposite the first main side, (b) applying a tint to both main sides of the substrate provided in step (a), and (c) applying a functional coloring to both main sides of the substrate provided with a tint on both main sides in step (b) by dip coating, thereby obtaining a substrate provided with a tint and a functional coloring on both main sides.

Abstract: The present invention relates to a method for providing a substrate on one face with a tint and a functional coloration, comprising the following steps (a) to (d): (a) supplying a substrate to be provided on one face with a tint and a functional coloration, the substrate comprising a semifinished part manufactured from transparent plastic and having a first main face and a second main face which lies opposite the first main face and has a convex shape, (b) applying a tint to both main faces of the substrate supplied in step (a), (c) applying a functional coloration to the second main face of the substrate provided with a tint on both main faces in step (b), the functional coloration being brought about by at least one photochromic dye and the at least one photochromic dye being present in a photochromic coat material forming a polymeric coat on the substrate, and (d) post-processing the substrate provided with a functional coloration on the second main face in step (c), in such a way that the tint on the firs
