The present invention relates to a method of removing thermosetting paint film using isopropyl alcohol, and more specifically, to a method of removing thermosetting paint film comprising the steps of: adding plastic resin coated with thermosetting paint film into a reactor including a mixed solution of isopropyl alcohol, phenoxy ethanol and alkali at a predetermined temperature; allowing the mixture to react for a short time; and then removing the separated paint film. This invention provides an excellent method to remove thermosetting paint film, prevents heat aging thus enabling to consistently maintain inherent physical properties and secure safety even after removal of the film due to the much lower reaction temperature with a solvent as compared to those in conventional methods, prevents deterioration in physical properties caused by remaining impurities, provides a low cost process with a simplified manufacturing process and enables to effectively recycle a large amount of plastic resin waste.
