ABSTRACT:
Imaging elements are prepared by a method in which an image is generated on a donor element and then transferred from the donor element to a receiver element by the steps of lamination and peeling. The donor element comprises a support, an image-forming layer and optional release and adhesive layers and the image is formed by imagewise laser-induced thermal ablation of the image-forming layer. The method is particularly useful for the preparation of lithographic printing plates as it avoids the need to employ alkaline developing solutions.
