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.

1. A method for making a thermal mass transfer donor element comprising the steps of:coating at least two layers simultaneously by co-extrusion, 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.
