Title:
POLYIMIDE PRECURSOR COMPOSITION, PREPARATION METHOD THEREFOR, AND POLYIMIDE SUBSTRATE MANUFACTURED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2019/004677
Kind Code:
A1
Abstract:
The present invention relates to a polyimide precursor composition, a preparation method therefor, and a polyimide substrate manufactured therefrom. The polyimide precursor composition has a low viscosity while containing a solid part in a high concentration, and thus is advantageous for manufacturing a substrate and has excellent room temperature storage stability. In addition, the polyimide substrate has excellent heat resistance and mechanical properties, and thus is suitably applicable as a display substrate.
