Title:
POLYIMIDE PRECURSOR COMPOSITION, AND PROCESS FOR PRODUCING INSULATING COATING LAYER USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/121817
Kind Code:
A1
Abstract:
The present invention relates to a polyimide precursor composition for forming insulating polyimide coating layers, characterized by comprising a specific polyamic acid and a specific phosphorus compound. The composition is further characterized in that the polyamic acid is one which, when heated under such conditions that the maximum heating temperature is 300-500ºC, can produce a polyimide film having a coefficient of water vapor permeability higher than 1.0 g·mm/(m2·24h).
