IN SITU DYE GENERATION FOR THERMAL TRANSFER PRINTING 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: Image wherein X is halogen, substituted or unsubstituted alkylsulfonyloxy, substituted or unsubstituted arylsulfonyloxy, or substituted or unsubstituted acyloxy; E1, E2, E3, and E4 are each independently hydrogen, substituted or unsubstituted alkyl or alkenyl having up to about six carbon atoms, substituted or unsubstituted aryl having up to about ten carbon atoms, halogen, cyano, benzoxazolyl, nitro, -CO2R, -COR, -CONH2, -CONHR, -CONRR, or -SO2R, wherein each R is independently substituted or unsubstituted alkyl or alkenyl having up to about six carbon atoms, or substituted or unsubstituted aryl having up to about ten carbon atoms, with the proviso that at least two of the E groups are other than hydrogen, alkyl, alkenyl, aryl or halogen; -ii- B1 and B2 represent the atoms necessary to complete optional five- or six-member rings formed with carbonyl moieties of E1, E2 or E3; B3 represents hydrogen or the atoms necessary to complete an optional five- or six-member ring with a carbonyl moiety of E1; and n is zero or one.
