Abstract:
A method for producing an aqueous polyimide precursor solution composition includes forming a polyamic acid by the reaction of a tetracarboxylic acid component and a diamine component in an aqueous solvent together with an imidazole in an amount of 1.6 mole or more per mole of the tetracarboxylic acid component of the polyamic acid.
