chromophoric portion of the dyes were prepared by a reaction of substituted phthalic anhydride with a carboxyethyl substituted resorcinol analogue followed by a condensation with a secondresorcinol analogue. In order to avoid an accumulation of symmetric side products, the second step was performed in two substeps: acid-catalyzed formation of a triphenylmethyl intermediate followed by base-catalyzed cyclization
