A compound of formula (I0): wherein R1 represents a substituent, R2 represents a hydrogen atom, or a substituent, R3 represents a hydrogen atom, or a substituent, Ring A represents an aromatic ring which can be substituted, and Ring B represents a 5-membered heteroaromatic ring which can be substituted, or a salt thereof.

Studies on UV/Vis Absorption Spectra of Azo Dyes. XX. On the Different Substituent Effects on the Absorption Maxima of Hydrazones and Benzenediazonium Ions

PMO theory predicts that substituent effects on the absorption maxima of benzenediazonium ions are partly contrary to those in hydrazones.Therefore, it seemed likely that azo coupling products absorbing at shorter wavelengths than the parent diazonium ion
