From 1893 until 1976, the Monroe Chemical Company sold Putnam Fadeless Dyes.  These dyes were used by consumers to color numerous types of textiles.  Using samples acquired from Putnam product displays of the 1920’s-1930’s, we developed a micellar electrokinetic capillary chromatographic (MEKC) method of analysis of fabrics containing these dyes.  Specifically, dye extraction, MEKC separation, and ultra-violet/visible detection conditions were optimized such that fingerprint" electropherograms were produced for each fabric and Putnam dye color combination analyzed.  Additionally, dyed fabrics were exposed to numerous lighting conditions prior to analysis such that photodegradation products could be observed.  Our method has utility in artifact conservation and forensic analysis.<br/>
