- A--[B--X--Y--Z].sub.2 (I)
- wherein
- A is selected from the group consisting of ##STR5## n is an integer of 1 or more; B is selected from the group consisting of --NHCOO--, --NHCONR--, --CONH-- and --NHCO--;
- R is a linear or branched C.sub.1 -C.sub.6 alkyl group which may have a substituent;
- X is a linear or branched alkylene group which may have a substituent;
- Y is a single bond, or a bonding group selected from the group consisting of --O--, --S--, --COO--, --OOC--, --NHCOO--, --OOCHN--, --CONH--, --NHCO--, --SO.sub.2 NH--, --NHSO.sub.2 --, --SO.sub.2 -- and --O.sub.2 S--; and
- Z is a hydrogen atom, a linear or branched alkyl group which may have a substituent and/or an unsaturated group, or a phenyl group.
- 3. A heat transfer image-receiving sheet according to claim 1, wherein said resin and said dye-transfer promoting agent are existing in the dissolved state.
- 4. A heat transfer image-receiving sheet according to claim 1, wherein said dye-receiving layer comprises a thermoplastic resin containing 0.1 to 8% by weight of nitrogen, and said dye-transfer promoting agent, and
- a releasing layer comprising a catalyst-setting releasing agent containing an unsaturated bond is further provided on the surface of said dye-receiving layer.
- 5. A heat transfer image-receiving sheet according to claim 4, wherein said thermoplastic resin has a glass transition temperature of 70.degree. C. or higher, said dye-transfer promoting agent has a melting point of from 60.degree. C. to 130.degree. C., and said dye-receiving layer has a softening point of 60.degree. C. or higher.
- 6. A heat transfer image-receiving sheet according to claim 4, wherein said thermoplastic resin is an urethane-modified polyester resin.
- 7. A heat transfer image-receiving sheet comprising:
- a substrate film,
- a dye-receiving layer formed on at least one surface of the substrate film, and
- a dye-transfer promoting layer formed on the dye-receiving layer, comprising a compound which is in a crystalline state at room temperature, and can be fused by thermal energy which is applied when heat transfer recording is conducted.
- 8. A heat transfer image-receiving sheet according to claim 7, wherein said dye-transfer promoting layer comprises a bis compound having the following formula (I):
- A--[B--X--Y--Z].sub.2 (I)
- wherein
- A is selected from the group consisting of ##STR6## n is an integer of 1 or more; B is selected from the group consisting of --NHCOO--, --NHCONR--, --CONH-- and --NHCO--;
- R is a linear or branched C.sub.1 -C.sub.6 alkyl group which may have a substituent;
- X is a linear or branched alkylene group which may have a substituent;
- Y is a single bond, or a bonding group selected from the group consisting of --O--, --S--, --COO--, --OOC--, --NHCOO--, --OOCHN--, --CONH--, --NHCO--, --SO.sub.2 NH--, --NHSO.sub.2 --, --SO.sub.2 -- and --O.sub.2 S--; and
- Z is a hydrogen atom, a linear or branched alkyl group which may have a substituent and/or an unsaturated group, or a phenyl group.
- 9. A heat transfer image-receiving sheet according to claim 7, wherein said dye-transfer promoting layer is present in an amount of from 0.01 to 1.0 g/m.sup.2.
