Popis:	Azomethine dyes were obtained by reaction of 1-methyl- and 1,2-dimethyl-3-arylbenzo[f]quinolinium methiodides with 1-nitroso-2-naphthol. Merocyanine dyes were isolated by the action of KOH on 2-hydroxy-5,6-benzostyryl derivatives of 3-arylbenzo[f]quinolinium salts. The absorption spectra of the dyes in ethanol and chloroform are presented, and it is shown that, as compared with the spectra of the merocyanines, there is a bathochromic shift of the absorption bands in the spectra of the azomethine dyes. The azomethine and merocyanine dyes have solvatochromic properties and display photosensitivity in the UV and visible regions when they are introduced into a polymer matrix.
