Polyester resin compositions each comprising a polyester resin and a silane-treated phyllosilicate, wherein the silane-treated foliated phyllosilicate is one prepared by incorporating a swellable phyllosilicate salt with organo-silane of the general formula (I): YnSiX4-n (wherein n is an integer of 0 to 3; Y is an optionally substituted C1-C25 hydrocarbon group; and X is a hydrolyzable group or hydroxyl, with the proviso that when n or 4-n is 2 or above, nY's or (4-n)X's may be the same or different from each other) and the maximum layer thickness of the silane-treated foliated phyllosilicate in the composition is larger than 100 Å but smaller than 2000 Å.
