A resin dispersion for dye receiving layer of a thermal transfer image-receiving sheet, including a polyester resin particle and an aqueous medium. The polyester resin particle includes a polyester resin that is a polycondensate of an alcohol component including at least one of a propylene oxide adduct of 2,2-bis(4-hydroxyphenyl)propane and an ethylene oxide adduct of 2,2-bis(4-hydroxyphenyl)propane, and a carboxylic acid component including an aliphatic dicarboxylic acid compound having a carbon number of 6 or more and 10 or less. A molar ratio of the propylene oxide adduct of 2,2-bis(4-hydroxyphenyl)propane to the ethylene oxide adduct of 2,2-bis(4-hydroxyphenyl)propane in the alcohol component is 0/100 or more and 40/60 or less. A molar ratio of the ethylene oxide adduct of 2,2-bis(4-hydroxyphenyl)propane to the aliphatic dicarboxylic acid compound having a carbon number of 6 or more and 10 or less is 2.1 or more and 15 or less.
