Aspects regarding colour fastness and adsorption studies of a new azo-stilbene dye for acrylic resins

Abstract The aim of this study was the colour fastness investigation of the new synthetized direct symmetrical azo-stilbene dye, using two of the film field domain reference tests, namely the wet-scrub and the UV tests. The dye was incorporated in a water-based resin, and then was applied on a PCV f...
