Abstract:
A polyimide precursor composition that exhibits excellent tensile strength and breaking elongation, and that provides a film containing an alicyclic polyimide resin; a method for producing a polyimide film using the polyimide precursor composition; and a permanent film that contains an alicyclic polyimide resin and that exhibits excellent tensile strength and breaking elongation. The polyimide precursor composition is a mixture of a resin precursor component which is a polyamic acid including an alicyclic backbone having a predetermined structure, a monomer component that includes an aromatic diamine compound having a predetermined structure or an alicyclic tetracarboxylic acid di-anhydride having a predetermined structure; an imidazole compound having a predetermined structure; and a solvent.

Claim (Index 3):
A method for producing a polyimide film, comprising:\n forming a coating film of the polyimide precursor composition according to  claim 1 ; and heating the coating film to ring-close a polyamic acid derived from a resin precursor component (B) in the coating film.
