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 4):
A permanent film comprising an imidazole compound (A) and a polyimide resin, wherein\n the imidazole compound (A) is a compound represented by the following formula (1): wherein, in the formula (1), R 1  is a hydrogen atom or an alkyl group, R 2  is an optionally substituted aromatic group, R 3  is an optionally substituted alkylene group, R 4  each independently represent a halogen atom, a hydroxy group, a mercapto group, a sulfide group, a silyl group, a silanol group, a nitro group, a nitroso group, a sulfonato group, a phosphino group, a phosphinyl group, a phosphonato group, or an organic group, and n is an integer of 0 to 3; and the polyimide resin is a resin in which a polyamic acid including a repeating unit as a main component represented by the following formula (b2): wherein, in the formula (b2), R b1 , R b2 , and R b3  each independently represent one selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, and a fluorine atom, R b10  represents an aryl group having 6 to 40 carbon atoms, and m represents an integer of 0 to 12 is ring-closed.
