Abstract

See full text

The invention relates to a selective dyeing method used for dyeing a substrate (10), selectively within a first exposed surface portion (S1) of said substrate. For this purpose, the substrate consists of a material (2) that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion (3) of the substrate in a second portion (S2) of the exposed surface. The substrate is heated such that the dye (C) penetrates a pervious material (1) which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.
