METHOD FOR PRODUCING POLYIMIDE FILM AND POLYAMIC ACID SOLUTION COMPOSITION

Disclosed is a method for producing a polyimide film, wherein a polyamic acid solution composition is coated on a base material and the resultant coating film is processed by heat treatment; the polyamic acid solution composition is obtained by introducing a specific chemical structure into a polyam...

Zusammenfassung:	Disclosed is a method for producing a polyimide film, wherein a polyamic acid solution composition is coated on a base material and the resultant coating film is processed by heat treatment; the polyamic acid solution composition is obtained by introducing a specific chemical structure into a polyamic acid at a ratio within a specific range; and the polyamic acid has a chemical structure composed of a 3,3',4,4'-biphenyltetracarboxylic acid component and/or a pyromellitic acid component, and a paraphenylenediamine component. Also disclosed is the polyamic acid solution composition.
