ABSTRACT:
In situ dye generation in a thermal transfer system is achieved by reacting an electrophile with a coupler compound to form an arylidene dye. The electrophile and/or the coupler compound are transferred from a donor element to a receiver element where they react to form a colored dye. The invention comprises a dye image recording element comprising a support bearing the electrophile which has the structure: ##STR1## wherein X is halogen, substituted or unsubstituted alkylsulfonyloxy, substituted or unsubstituted arylsulfonyloxy, or substituted or unsubstituted acyloxy;
