Abstract
Provided is 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, in which the composition includes 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 5 ppm to 25 ppm/3 ppm to 30 ppm of a titanium (Ti)-germanium (Ge) composite catalyst compound (based on an amount of Ti/Ge), based on weight percentage.
