Abstract
A thermal mass transfer donor element is provided that includes a thermal transfer layer and a light-to-heat conversion layer, wherein the light-to-heat conversion layer has at least two regions exhibiting different absorption coefficients. The thermal transfer donor elements provided can improve imaging performance by increasing transfer sensitivity and decreasing imaging defects.
Claims31
A thermal mass transfer donor element comprising:
- a substrate;
- a thermal transfer layer capable of being selectively transferred from the donor element to a proximately located receptor;
- and
- a non-homogeneous light-to-heat conversion layer disposed between the substrate and the transfer layer, the non-homogeneous light-to-heat conversion layer comprising a radiation absorber and having at least two regions that exhibit different absorption coefficients, wherein each of the at least two regions comprises the radiation absorber.
