    Das Färben von Polyacrylnitrilfasern mit Azatrimethincyaninen (1962)
    Weinheim : Wiley-Blackwell

    Notes: Azatrimethincyanine besitzen wie alle basischen Farbstoffe auf Polyacrylnitrilfasern ein gutes Ziehvermögen. Verbindungen mit isoliert stehenden Stickstoffatomen in der Methinkette weisen ungenügende Lichtechtheiten auf, wogegen diejenigen mit vicinalen Stickstoffatomen in der Methinkette gute bis ausgezeichnete Lichtechtheiten zeigen. Damit ist eine Arbeitshypothese teilweise bestätigt worden, wonach durch steigenden Ersatz der Methingruppen durch Stickstoffatome die Lichtechtheit der Trimethincyanine auf Polyacrylnitrilfasern verbessert wird.

    Dyeing of Poly(acrylonitrile) Fibers with Azatrimethinecyanines (1962)
    Weinheim : Wiley-Blackwell
    Angewandte Chemie International Edition in English 1 (1962), S. 532-537 
    Details
    ISSN: 0570-0833

    Notes: Like all basic dyes, azatrimethinecyanines possess a good dyeing affinity for acrylic fibers. Compounds with isolated nitrogen atoms in the trimethine chain show insufficient light fastness, whereas good to excellent fastness to light is displayed by compounds having neighboring nitrogen atoms in the chain. Thus, a working hypothesis stating that the light fastness of trimethinecyanines on acrylic fibers is improved by progressive replacement of methine groups by nitrogen atoms has been partially confirmed.
