Thermal transfer image-receiving material

A thermal transfer image-receiving material having an image-receiving layer comprising a thermoplastic resin capable of receiving a dye, on a support, wherein the thermoplastic resin is a polyester obtained by poly-condensation of monomers represented by formula (1), (2), (3) and (4) of monomers represented by formula (1), (2), (5) and (6):
