This paper presents the synthesis of a new symmetrical disazo direct dye with good coloring properties for acrylic resins and several theoretical approaches to choose the best simulation method of the dye structure and spectra. The synthesized dye contains 4,4′-diaminostilbene-2,2′-disulfonic acid,...
