CHARACTERIZATION OF ISOBARIC SPECIES AND PHOTO-DEGRADATION PRODUCTS OF TRIARYLMETHANE DYES WITHIN TEXTILES

摘要

Since mid-19th century, triarylmethane dyes were widely used for ink production and dyeing textiles [1]. These dyes, characterized by bright hues, are one of the first classes of synthetic dyes produced and marketed [2]. Nevertheless, their analysis is highly complicated due to their poor light fastness and their complex composition constituted by homologous species, often differing only for the presence or position of the same substituent on the aromatic rings.
