SUBLIMATION TRANSFER IMAGING SYSTEM

摘要

SUBLIMATION TRANSFER IMAGING SYSTEM A process for forming an image which comprises image-wise exposing to radiation of selected wavelength a carrier element comprising, as image forming components, in one or more imaging layers coated on a support a bleachable dye in reactive association with iodonium ion thereby bleaching the dye in exposed areas to form a positive image, and thereafter transferring the positive dye image to a receptor which is either a receptor layer present on the carrier or a separate receptor element by heating the carrier element to a sufficient temperature to allow the dye image to sublime to the receptor thereby forming an image on the receptor.
