WATER-DISPERSIBLE POLYESTER RESIN HAVING IMPROVED WATER RESISTANCE AND CHEMICAL RESISTANCE, WATER-DISPERSION EMULSION CONTAINING SAME, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a water-dispersible polyester resin having improved water resistance and chemical resistance, a water-dispersion emulsion containing the same, and a preparation method thereof. The present invention can minimize the use of organic solvents to be added to a water-dispersible polyester resin to thereby reduce hazard to a human body, does not create odor by excluding a use of amines, and can prepare a water-dispersion emulsion having excellent coating, adhesive property, and water-dispersion stability without using emulsifiers such as surfactants.
