ABSTRACT:
Process for forming at least a single color image on a receptor material using photohardenable elements which contain one or more imagewise photohardenable layers toned with a toner material comprising a sublimable dye or mixture of dyes, the process comprising heating for at least 5 seconds, while in contact with a receptor material, either the toned element, the receptor material, or both, to a sublimation temperature of said dye and thereby cause at least a portion of the dye to sublime imagewise and condense on the receptor material. The temperature should not degrade the receptor or photohardenable layer. At least one non-imagewise exposed photohardenable layer may be present in the toned element. The process is useful in forming color proofs or proposed fabric patterns, color prints, projector overlays, etc.
