Abstract
A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes ethyl cellulose as a binder. The dye-donor element is capable of printing a defect-free image on a receiver element at a line speed of 2.0 msec/line or less while maintaining a print density of at least 2.0.
Claims26
A method of printing, comprising
- obtaining a donor comprising a support and a dye layer, wherein the dye layer comprises a binder and a dye, the binder comprising ethyl cellulose;
- obtaining a receiver having a support and a dye-receiving layer on the support;
- placing the dye layer of the donor adjacent the dye-receiving layer of the receiver;
- and
- applying heat in an imagewise fashion to the donor to form a dye image on the receiver,
- wherein the image is formed at a line speed of 2 msec or less.
A dye-donor element comprising a support and a dye layer, wherein the dye layer comprises a dye and a binder, the binder consisting essentially of a first ethyl cellulose with an ethoxyl content of 50.5% or greater, and a second ethyl cellulose with an ethoxyl content of less than 50.5%.
A print assembly comprising a donor and a receiver,
- wherein the donor comprises a support and a dye layer, wherein the dye layer comprises a binder and a dye, the binder comprising ethyl cellulose, and
- wherein the receiver comprises a support and an extruded dye-receiving layer on the support.
