Claims
- 1. A method for making a thermal mass transfer donor element comprising the steps of:
coating at least two layers, each layer comprising an absorber material dispersed in a crosslinkable binder, and crosslinking the crosslinkable binders of the layers to form a non-homogeneous light-to-heat conversion layer between a donor substrate and a thermal transfer layer, wherein the donor element is capable of being used for imagewise thermal mass transfer of material from the thermal transfer layer to a proximately located receptor when the donor element is exposed to imaging radiation that can be absorbed and converted into heat by the non-homogeneous light-to-heat conversion layer.
- 2. The method of claim 1, wherein the at least two layers are coated sequentially.
- 3. The method of claim 1, wherein the at least two layers are coated simultaneously by co-extrusion.
- 4. The method of claim 1, wherein crosslinking of the crosslinkable binder of each layer is performed after coating said layer but before coating the next layer.
- 5. The method of claim 1, wherein all of the at least two layers are coated before the crosslinking step is performed.
- 6. The method of claim 1, wherein crosslinking the crosslinkable binders of all the at least two layers is performed simultaneously.
