Abstract
A thermal transfer donor element is provided which can include a support, light-to-heat conversion layer, interlayer, and transfer layer. When the donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. In order to enhance the lifetimes of the transferred material, thermal treatments such as annealing are applied to the receptor before transfer, to the transfer layer after transfer, or a combination of them. The construction and process of the donor element is useful in making colored images including applications such as color proofs, color filter elements, and organic light emitting diode displays and devices.
