The invention provides a thermoset scratch-resistant touch screen hardening film (IMO) conducting film and a preparation method of the film; the film comprises a polyethylene glycol terephthalate (PET) base film; a scratch-resistant coating layer is arranged on the upper surface of the PET base film; a conductive layer coating is arranged on the lower surface of the PET base film; a conductive layer is transparent; and the scratch-resistant coating layer is a heat-cured coating layer. The preparation method comprises the steps of: carrying out corona on the PET base film; coating on the PET base film; drying the coated PET base film; carrying out heat curing on the dried PET base film; after that, curing the PET base film; rolling; coating the transparent conductive layer on the back of the rolled PET base film; and drying, curing, rolling, slitting to obtain the thermoset scratch-resistant IMO conducting film. The thermoset scratch-resistant IMO conducting film is simple in structure, good in flexibility, hi
