    Abstract: A plasticizer made of an ester prepared from a hydroxycarboxylic acid is new, and an amorphous polyester resin composition comprises this plasticizer and amorphous polyester resin. The plasticizer contains at least one ester selected from (A), (B), (C) and (D). (A) is an ester prepared from (Aa) and (Ab). (Aa) is at least one ester selected from esters of a hydroxyaromatic carboxylic acid represented by general formula (A1), esters of a hydroxycondensed polycyclic aromatic carboxylic acid having at least one OH or COOH group, esters of a hydroxyalicyclic carboxylic acid, ester anhydrides of these carboxylic acids, and 1-3C alkyl esters of these carboxylic acids. (Ab) is at least one compound hydroxy compound selected from aliphatic alcohols, alicyclic alcohols, aromatic alcohols, phenols, alkylphenols or 2-4C alkylene oxide additions of these alcohols. [Image] X a>H, OH, 1-22C alkyl, alkenyl, alkoxy group or halogen atom; n, m : integer 1 or more; n+m : 5; p : 0, 1, 2 or 3. (B) is an ester prepared from (Ba) and (Bb). (Ba) is at least one ester selected from esters of hydroxyaromatic carboxylic acid represented by general formula (B1), esters of a hydroxycondensed polycyclic aromatic carboxylic acid having at least one OH or COOH group, esters of a hydroxyalicyclic carboxylic acid, ester anhydrides of these carboxylic acids, or 1-3C alkyl ester of these carboxylic acids.
