Zusammenfassung:A print assembly including a dye-donor element and a receiver element, wherein the print assembly has a donor having a dye-donor layer having a first glass transition temperature and at least one dye, and a receiver having a dye-receiving layer having a second glass transition temperature on a support, wherein the print assembly has a receiver/donor dye partition coefficient of at least 2.5 when the print assembly is heated above the higher of the first or second glass transition temperature for a time sufficient to achieve an equilibrium state of dye distribution between the dye-donor layer and dye-receiving layer. The print assembly can be used at fast print speeds of 2.0 msec/line or less.
