Abstract
Novel cyano hydroxy pyridone monoazo yellow dye compounds are useful in thermoplastic electrostatographic toners. They absorb at the desired wavelength, are lightfast and have high tinctorial strength. They resist decomposition, sublimation and bleeding upon being thermally fixed to a substrate. For use in color transparencies, these dyes form a transparent toner image.
