摘要：

This paper aims to explain the variation of (UV-Vis) spectral parameters of pre-formed azo chromium (1:1) complex dyes, containing the sulfonic group in the diazotation component, having aryl-azo-pyrazolone and aryl-azo-naphtaline type structures, (aryl=benzene, naphtaline) versus spectral parameters of (1:1) chromium complex of azo dyes (A): 2-aminophenol-4-sulphonic acid -> acetoacetanilide and (B): 1-diazo-2-naphtol-4- sulphonic add acetoacetanilide, considered as reference structures, taking into account the electronic effects (sigma, pi) of substituents.
