Title:

STYRENE DERIVATIVE AND PREPARATION METHOD THEREFOR, MODIFIED ORGANIC SILICON RESIN AND PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/267440

Kind Code:

A1

Abstract:

The present invention provides a styrene derivative and a preparation method therefor, a modified organic silicon resin and a preparation method therefor, and an application thereof, and belongs to the technical field of back coating liquids. The styrene derivative provided in the present invention is specifically 2,3-difluoro-4-methoxystyrene; in the present invention, a fluorine atom is introduced to a benzene ring structure, and the resulting styrene derivative comprises a C-F bond having a relatively high chemical bond energy, such that the styrene derivative has a relatively high thermal stability; with the styrene derivative being introduced into an organic silicon resin, the resulting modified organic silicon resin can have a relatively high thermal stability; and the heat resistance of a back coating liquid for a heat transfer printing barcode ribbon can be effectively improved when the modified organic silicon resin is used as the back coating liquid for the heat transfer printing barcode ribbon.
