  • Patent number: 4869996
    Abstract: An improved process for preparing negative images from a photohardenable tonable element, wherein the unexposed photohardenable tonable element is tacky in a preselected temperature range, T.sub.1 -T.sub.2, in which temperature range the exposed photosensitive tonable element is nontacky but wherein the exposed element is retackifiable at elevated temperatures above T.sub.2. After imagewise exposure the unexposed areas have a colorless toning material applied to them at a temperature within the range T.sub.1 -T.sub.2 to make them nontacky at temperatures of at least up to T.sub.3, which is greater than T.sub.2. After heating to an elevated temperature above T.sub.2 but less than T.sub.3 the exposed areas have a contrasting toning material applied to them to give a negative or reverse image.
