Sample book for Palatine fast dyes, a trade name for metal-complex dyes where chromium is incorporated into the dyestuffs molecule by the manufacturer. The process for Palatine fast dyes was achieved around 1915 by I.G. Farben Industries AG, and the dyes were widely used for wool in "suitings and better dress goods," as well as "knitting, weaving, and carpet yarns." The text describes the dyeing process and contains mounted yarn samples with dye concentrations and information on color fastness to various effects, such as washing, milling, and perspiration.
