PURPOSE: Provided is a polybutylene terephthalate resin composition with excellent aluminum deposition, wherein adhesiveness of the aluminum is not lost, 6039even though the composition is exposed at high temperature for a long time. CONSTITUTION: The polyester resin composition comprises (i) 40-90 wt% of polybutylene terephthalate(PBT) resin, (ii) 5-30 wt% of polyethylene terephthalate(PET) resin, (iii) 0.1-5 wt% of reaction catalyst having epoxy and PBT carboxyl terminal groups, (iv) 0.1-10 wt% of epoxy compound having at least 2 epoxy groups, and (v) 2-30 wt%(based on total of the (i), (ii), (iii), and (iv)) of glass fiber and mineral filler. The epoxy compound(iv) is selected from the group consisting of polyglycidyl ether, polyglycidylamine epoxy, bisphenol A epoxy, bisphenol F epoxy, resorcinol epoxy compound, tetrahydroxy bisphenol F epoxy compound, cresol novolac epoxy compound, phenol novolac epoxy compound, and cycloaliphatic epoxy compound. |
