The alcohol soluble 3,3'-diethylthiacarbocyanine bromide dye (TCC), whose structure is shown below is a useful charge generation compound for use in photocopying. The quality of the coatings obtained by casting TCC from alcoholic solutions such as from methanol or ethanol is very good. This is also true when TCC is coated as a dispersion in polymer from alcohol solutions. Thus, TCC is coated either neat or as a dispersion in a polymer, whereupon a charge transport layer is then overcoated.
