Abstract

One of the purposes of investigating the mechanisms of Weigert's effect in azo-dye-colored materials is the search for ways to improve their corresponding characteristics. So far the suggested mechanisms based on the isomerization process of the molecules of the dyes do not account for some facts that take place in this case. I present some results of the investigation of Weigert's effect in azo-dye-colored materials and propose a possible new mechanism.
