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.
