Abstract
A polyester resin composition includes: (A) polycyclohexylenedimethylene terephthalate (PCT) resin which is a polymer of terephthalic acid and cyclohexanedimethanol, wherein the cyclohexanedimethanol has a trans/cis isomer ratio of about 2.3 or more; (B) a white pigment, wherein the white pigment is titanium dioxide; and (C) inorganic fillers, wherein the inorganic fillers are glass fibers. A molded article formed from the polyester resin composition can exhibit improved mechanical properties and moldability, and thus can be suitable for light emitting diode (LED) reflectors.
