Abstract
(EN)
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. As a result, provided is a method for drying a polyimide paste which can maintain productivity and printed shape.

La présente invention concerne un procédé de séchage d'une pâte de polyimide qui contient un solvant organique et une résine de polyimide dissoute dans le solvant organique, et qui est durcie en polyimide durci par séchage et chauffage. Le procédé est caractérisé en ce qu'il comprend : une étape d'application de la pâte de polyimide sur une surface d'un substrat ; une étape d'application d'un solvant contenant une substance polaire sur au moins une surface d'une partie du substrat sur laquelle la pâte de polyimide a été appliquée ; et, après application du solvant contenant la substance polaire, une étape de séchage de la pâte de polyimide et du solvant contenant la substance polaire. En conséquence, l'invention concerne un procédé de séchage d'une pâte de polyimide qui peut maintenir la productivité et la forme imprimée.
