Title:
POLYIMIDE PRECURSOR COMPOSITION, POLYIMIDE FILM, AND POLYIMIDE FILM/SUBSTRATE LAMINATE
Document Type and Number:
WIPO Patent Application WO/2022/114136
Kind Code:
A1
Abstract:
Provided is a polyimide precursor composition with which it is possible to manufacture a polyimide film that has excellent thermal characteristics and/or thermal resistance, and that has excellent transparency. The polyimide precursor composition comprises a repeating unit including a repeating unit expressed by the following general Formula (I) and a repeating unit obtained by further imidizing the general Formula (I), and contains a polyimide precursor having an imidization ratio of more than 0% and less than 50% and a solvent. (where 70 mol% or more of X1 is a structure expressed by Formula (1-1), and 70 mol% or more of Y1 is a structure expressed by Formula (D-1) and/or (D-2).)
