Abstract
The specification describes a new group of alkanol substituted disazo compounds that are useful in dyeing polyamide textile fibers in orange hues. The new compounds are compatible with several acid blue dyes and several acid red dyes that are commercially important as dyes for nylon. The new compounds are particularly well suited for use as the "yellow" component in trichromatic systems for dying polyamide carpeting and other textiles. The new compounds are relatively inexpensive to make and have outstanding application and fastness properties. Other aspects of the specification are concerned with a method of making the new compounds and with a method of dyeing polyamides with said compounds and to the novel dyed polyamides resulting from the use of the new group of compounds as dyes.
