Document Type and Number:
WIPO Patent Application WO/2023/149484
Kind Code:
A1
Abstract:
The present invention pertains to a polyester resin composition, wherein sufficient mold releasability is achieved and fogging and bleed-out are suppressed even when the composition is molded into a product having a complex shape or thin-walled parts. The polyester resin composition contains 0.01-4 parts by mass of a release agent (B) per 100 parts by mass of a polyalkylene terephthalate resin (A), and the release agent (B) contains two or more kinds of fatty acid ester compounds each composed of a polyhydric aliphatic alcohol and a fatty acid. It is preferable that the release agent (B) contains a fatty acid ester compound (B1) composed of a hexahydric aliphatic alcohol and a C5-30 fatty acid, and a fatty acid ester compound (B2) composed of a dihydric to tetrahydric aliphatic alcohol and a C5-30 fatty acid.
