| abstract | (57) [Problem] To provide a resin composition in which the toughness (tear strength, tensile elongation at break) of polyethylene terephthalate and / or polyethylene naphthalate is improved without impairing transparency. SOLUTION: An aromatic crystalline polyester resin (A) composed of polyethylene terephthalate and / or polyethylene naphthalate (A) has an acid component of 60 mol% or more and tetramethylene glycol in an amount of 60 mol% or more based on 5 to 99.5 wt%. Hard segment 20 which is polybutylene terephthalate as a diol component of at least mol% 0.5 to 95% by weight of a polyester block copolymer (B) of 80 to 20% by weight and 80 to 20% by weight of a soft segment which is a polyester containing an aromatic dicarboxylic acid as an acid component and hexamethylene glycol as a diol component. %. A polyester resin composition characterized by having a scattered light amount (haze) of 5% or less when formed into a sheet-shaped molded article having a thickness of 300 μm. |
