Patent ID: 8653224

Claim:
A composition for manufacturing a polyester resin having a molar ratio of a diol compound to a dicarboxylic acid compound ranging from 1.05 to 1.4, wherein the composition comprises 5 ppm to 50 ppm of a phosphorous (P) compound (based on an amount of P), 10 ppm to 40 ppm of a cobalt (Co) compound (based on an amount of Co), 0.2 ppm to 20 ppm of a color enhancer, and 8 ppm to 15 ppm/3 ppm to 16 ppm of a titanium (Ti)-germanium (Ge) composite catalyst compound (based on an amount of Ti/Ge), based on weight percentage, wherein a value of color coordinate L is 75.0 or more, a value of color coordinate b is 0.0 or less, and inherent viscosity (I.V) is in a range of 0.70 dl/g to 0.9 dl/g.
