Abstract:
1. A polyester resin composition comprising, on a weight basis, 30 ppm or less of antimony, 0.5 to 50 ppm, in terms of titanium, of a titanium compound having at least one substituent selected from the group consisting of an alkoxy group and an acylate group, and 0.1 to 100 ppm, in terms of phosphorus, of ethyl diethylphosphonoacetate, wherein the number of titanium-containing particles having an equivalent circular diameter of 1 μm or more is less than 100/0.02 mg of the composition; the alkoxy group in the titanium compound is at least one functional group selected from the group consisting of a β-diketone-system functional group, a hydroxycarboxylic acid-system functional group, and a ketoester-system functional group; and the acylate group in the titanium compound is either a multivalent carboxylic acid-system functional group or a nitrogen-containing multivalent carboxylic acid-system functional group.
