摘要: Dyes of the formula: ##SPC1##In whichR is unsubstituted or substituted alkyl or aralkyl;R.sup.1 to R.sup.6 is each hydrogen or a substituent;R.sup.7 is hydrogen or alkoxy;R.sup.8 is hydrogen or alkoxy;n is zero or 1;X.sup.- is an anion; andR.sup.1 and R.sup.8 may together be a radical: ##SPC2##Where R.sup.9 is hydrogen, alkyl or alkoxy; and at least one of the radicals R.sup.1 to R.sup.6 is arylmercapto.The dyes give bright colorations, particularly on polyesters and in resins.
