ABSTRACT:
A process for preparing images on a tonable, light-sensitive layer in which a transfer layer containing a toner and a core/shell polymer as a binder is used. The core polymer has a glass transition temperature above 50.degree. C. and the shell polymer has a glass transition temperature below 40.degree. C. Such transfer layers are used in proofing processes for high quality printing.
