Abstract
Fifteen merocyanine dyes are prepared by condensing N-arylquinaldine salts with ethoxymethylenephenylrhodanine and acetanilomethyleneethylrhodanine. These have not previously been described in the literature and are characterized. The absorption spectra of the dyes in the visible region are observed.
