Abstract

An imaging process uses an imaging medium comprising a polymer having a plurality of first groups. This polymer is imagewise contacted with an imaging reagent comprising a plurality of second groups, thus causing, in the areas of the medium exposed to the imaging reagent, the second groups to react with the first groups and form a colored material, and thereby forming an image on the imaging medium. One of the first and second groups comprises a benzotriazinone or benzothiatriazine-4,4-dioxide benzotriazinone moiety and the other comprises a naphthol or a pyrazalone moiety.
