ABSTRACT:
A dye compound of a general formula (I): ##STR1##
where R.sub.1 represents a hydrogen atom, or a substituent; R.sub.2 and R.sub.3 independently represent a substituent; X represents a nitrogen atom or --C(R.sub.5).dbd.; R.sub.5 represents a substituent; and R.sub.4 represents an aromatic group or an unsaturated heterocyclic group as bonded to the nitrogen atom in the formula via an unsaturated carbon atom, which dye compound is fast to heat and light and is useful for color image formation and as a filter dye; and a thermal transfer dye donating material having a dye donating layer containing a thermal transferring dye on a support, where the thermal transferring dye is represented by: ##STR2##
where X.sup.2 represents --N.dbd., or --C(R.sup.22).dbd.; R.sup.21, R.sup.22, R.sup.23 and R.sup.24 independently represent a hydrogen atom, or a non-metallic substituent; R.sup.25, R.sup.26, R.sup.27 and R.sup.28 independently represent a hydrogen atom, or a substituent substitutable on the benzene ring in the formula; R.sup.29 and R.sup.210 independently represent a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group; and R.sup.21 and R.sup.22, and/or R.sup.22 and R.sup.23, and/or R.sup.21 and R.sup.24, and/or R.sup.25 and R.sup.26, and/or R.sup.26 and R.sup.29, and/or R.sup.29 and R.sup.210, and/or R.sup.27 and R.sup.210, and/or R.sup.27 and R.sup.28 each combine and form a ring.
