A resin composition consisting essentially of (A) an aromatic copolyester derived from (1) a mixture of terephthalic acid and isophthalic acid and/or the functional derivatives thereof and (2) a bisphenol and/or the functional derivatives thereof; (B) a polyamide; and (C) a compound of a metal of Gr

A resin composition consisting essentially of (A) an aromatic copolyester derived from (1) a mixture of terephthalic acid and isophthalic acid and/or the functional derivatives thereof and (2) a bisphenol and/or the functional derivatives thereof; (B) a polyamide; and (C) a compound of a metal of Groups IVB, VB, VIB, VIIB, VIII, IB, IIB, IIIA, IVA or VA of the Periodic Table. An article molded from the resin composition exhibits high heat resistance, mechanical properties and moldability. It is particularly resistant to cracking upon impact, and is also resistant to breaking at a thin walled portion.
