Ink jet printing with metal complex

A dye-donor element comprising a support having on one side thereof a dye layer comprising a dye precursor dispersed in a polymeric binder, the dye precursor having the following structure: ##STR1## and the support having on the other side thereof a slipping layer.

Dye-donor element for thermal dye transfer

A multicolor dye-donor element for thermal dye transfer capable of producing improved color gamut comprising a support having thereon a set of sequential repeating dye patches of yellow, magenta and cyan image dyes dispersed in a polymeric binder, the element also having at least one additional dye patch comprising a dye dispersed in a polymeric binder, the dye of each such additional dye patch which, when transferred to a dye image-receiving layer before or after transfer of the original yellow, magenta and cyan image dyes, has a hue measured at its maximum density which is outside the color gamut defined by the hues of the original transferred yellow, magenta and cyan image dyes by more than 5 CIELAB .DELTA.E.sub.c units.

Dye sets for thermal imaging having improved color gamut

A thermal dye transfer assemblage comprising:
