Claims16
Dye-donor element for use according to thermal dye transfer methods, said element comprising a support having thereon a dye layer comprising a dye layer carried by a polymeric binder resin, characterized in that said dye is an azo dye corresponding to the following general formula (I):
- ##STR65## wherein each of R.sup.1 to R.sup.4 independently represent hydrogen, an unsubstituted alkyl group, a cycloalkyl group or an aryl group, or R.sup.1 and R.sup.2 and/or R.sup.3 and R.sup.4 may be joined together to form a 5- or 6-membered heterocyclic ring system, or each of R.sup.1 to R.sup.4 independently can be joined to the carbon atom of the aromatic ring at a position ortho to the position of attachment of the anilino nitrogen to form a 5- or 6-membered ring;
- X and Y independently represent a substituent;
- selected from the group consisting of SH, OH, halogen, NO.sub.2, CN, alkyl, amino, carbonamido, sulfonamido, acylamido, sulfonylamino phosphorylamino, alkoxy, thialkoxy, alkoxycarbonyl and aryloxycarbonyl;
- n represent 0, 1, 2, 3, or 4, X substituents may be the same or different when is greater than 1;
- n' represents 0, 1, 2, 3 and 4, and Y substitutents may be the same or different when n' is greater than 1.
Dyed receiving element comprising a support provided with a dye-image receiving layer containing dyes in imagewise distribution, formed by thermal dye sublimation transfer using a dye-donor element comprising a support having thereon a dye layer comprising a dye carried by a polymeric binder resin, characterized in that said dye in an azo dye corresponding to the following general formula (I):
- ##STR68## wherein each of R.sup.1 to R.sup.4 independently represented hydrogen, an unsubstituted alkyl group, a cycloalkyl group or an aryl group, or R.sup.1 and R.sup.2 and/or R.sup.3 and R.sup.4 may be joined together to form a 5- or 6-membered heterocyclic ring system, or each R.sup.1 to R.sup.4 independently can be joined to the carbon atom of the aromatic ring at a position ortho to the position of attachment of the anilino nitrogen to form a 5- or 6-membered ring;
- X and Y independently represent a substituent selected from the group consisting of SH, OH, halogen, NO.sub.2, CN, alkyl, amino, carbonamido, sulfonamido, acylamino, sulfonylamino, phosphorylamino, alkoxy, thioalkoxy, alkoxcarbonyl and aryloxycarbonyl;
- n represents 0, 1, 2, 3 or 4, the X substituents may be the same of different when n is greater than 1;
- n' represents 0, 1, 2, 3 to 4, the Y substituents may be the same different when n' is greater than 1.
