POLYESTER RESIN COMPOSITION AND MOLDED ARTICLE DECORATED WITH HOT-STAMPING FOIL

WIPO Patent Application WO/2022/202830

A1

A polyester resin composition capable of giving molded articles which are highly rigid and, despite this, have few appearance failures due to, for example, the lifting of reinforcing fibers and have a satisfactory mirror appearance and excellent surface smoothness and which can be decorated by hot stamping. The polyester resin composition comprises 30-55 parts by mass of a poly(butylene terephthalate) resin (A), 8-38 parts by mass of a poly(ethylene terephthalate) resin (B), 3-20 parts by mass of one or more copolyester resins (C), 0-8 parts by mass of a polycarbonate-based resin (D), and 4-23 parts by mass of a carbon fiber reinforcement (E). The copolyester resins (C) comprise a poly(ethylene terephthalate) copolymer resin (C1) and/or a poly(butylene terephthalate) copolymer resin (C2). The polyester resin composition contains a transesterification inhibitor (F) in an amount of 0-2 parts by mass per 100 parts by mass of the sum of the (A), (B), (C), (D), and (E) and has a flexural modulus of 5.8 GPa or greater.
