Abstract: The present disclosure provides a styrene derivative and a preparation method thereof, and a modified organic silicone resin and a preparation method and use thereof, and belongs to the technical field of back coating solutions. The styrene derivative is specifically 2,3-difluoro-4-methoxystyrene. A fluorine atom is introduced into a benzene ring structure, and the obtained styrene derivative contains a C—F bond with a relatively high chemical bond energy, such that the styrene derivative has a relatively high thermal stability. The styrene derivative can be introduced into an organic silicone resin to make the obtained modified organic silicone resin have a higher thermal stability. The modified organic silicone resin can be used as a back coating solution to effectively improve a heat resistance of barcode thermal transfer ribbons.
