ABSTRACT:
Room temperature stable aqueous dispersions of ketone resins are prepared by dissolving poly(ethylene oxide) resin and optionally surfactant in the aqueous medium mixed with the ketone resin. Coating formulations with these dispersions can contain additional co-dispersed components such as waxes, additional resins and/or pigments. The coating formulations can provide thermal transfer layers of thermal transfer ribbons which contain both wax and ketone resins.
