VerfahrenzurDarstellungindigoiderKüpenfarbstoffe.
Es wurde gefunden, dass man sehr wertvolle indigoide Küpenfarbstoffe erhält, wenn man die α-Derivate, vorzugsweise die α-Arylide halogensubstituierter Isatine und Naphtisatine auf 3-Phenyi-l-indanon und dessen Substitutionsprodukte, Homologe oder Analoge, einwirken lässt.
Von den in den Monatsheften für Chemie, Band 31, S. 60 sowie in den deutschen Patent- schriften Nr. 227862 und 232369 beschriebenen vom α- und ss-Indanon sich ableitenden Farb- stoffen unterscheiden sich die nach vorliegendem Verfahren erhältlichen Farbstoffe durch ihre

Process for the preparation of indigoid vat dyes.
It has been found that very valuable indigoid vat dyes are obtained if the α-derivatives, preferably the α-arylides of halogen-substituted isatins and naphthisatins, are allowed to act on 3-phenyl-1-indanone and its substitution products, homologues or analogs.
The dyes obtainable according to the present process differ from the dyes described in the monthly magazine for chemistry, volume 31, p. 60 as well as in the German patent documents Nos. 227862 and 232369, which are derived from α- and ss-indanone

excellent clarity and fastness of the cotton dyeings, while the above-mentioned indallone dyes are of no importance as cotton dyes, since they only dye this fiber in weak, unsightly shades, moreover the?
- and ss-indanone dyes according to the information in German Patent No. 231542, an aftertreatment, which is not necessary with the present dyes.
Example.
