The present invention addresses the problem of providing a polyester film having a good surface state and being provided with both hydrolysis resistance and visible-light shielding properties, and suppressing the formation of irritant gas in the manufacturing process. The present invention relates to a polyester resin composition including a compound represented by general formula (1), a pigment, and a polyester. The present invention further relates to a master pellet, a polyester film, a back sheet for a solar cell module, and a solar cell module. In general formula (1), R2 represents an alkyl group which may have a substituent, a cycloalkyl group which may have a substituent, an aryl group which may have a substituent, or an alkoxy group which may have a substituent, R3 represents a specific alkyl group or a specific aryl group, and R11, R12, and R13 each independently represent a hydrogen atom, an alkyl group which may have a substituent, or an aryl group which may have a substituent. |
