Document Type and Number:
WIPO Patent Application WO/2019/082495
Kind Code:
A1
Abstract:
The present invention provides a method for drying a polyimide paste which contains an organic solvent and a polyimide resin dissolved in the organic solvent, and is cured into cured polyimide by drying and heating. The method is characterized by comprising: a step for applying the polyimide paste to a surface of a substrate; a step for applying a solvent containing a polar substance to at least a surface of a portion of the substrate to which the polyimide paste has been applied; and a step for, after applying the solvent containing the polar substance, drying the polyimide paste and the solvent containing the polar substance.
