Abstract
There is provided by the present invention a thermal transfer ribbon which provides images with high resistance to scratch and smear through the use of high loadings of water soluble, dispersible and emulsifiable thermoplastic resins with a water dispersible or emulsifiable wax. The thermoplastic resins are sufficiently compatible with the wax so as not to separate at high concentrations of thermoplastic resin and wax. Coating formulations which provide these thermal transfer ribbons and the images obtained from such ribbons are also provided.
