Aniline Dye
 
Aniline Dyes were first synthetic dyes used as a cheap alternative to vegetal ones.  They were first developed in Europe in the 1850s but were shortly discovered to poses rapid fading qualities with exposure to light and water.  They were banned in Iran in the early 1900, and eventually replaced with Chrome synthetic dyes everywhere else.
