EMPFAENGER FUER THERMISCHE UEBERTRAGUNG.

摘要

A receiver sheet for dye-diffusion thermal transfer printing, comprises a substrate which supports a receiver coat, the receiver coat comprising a dye-receptive material, such as an organic polymer, and a dye-permeable release agent which is a thermoset amino-modified-silicone organic-oligoepoxide resin. The thermoset combination of silicone and organic moeties in the release agent, gives good protection against adhesion between the dyesheet and receiver sheet when they are subjected to short high temperature pulses during printing, while also enabling sharp images of high optical density to be obtained. This balance of properties is best obtained by dispersing the release agent throughout the dye-receptive material, although they can also be applied to the substrate as separate layers.
