Polyimide precursor solution, process for producing the solution and moldings and coatings obtained therefrom
 A polyimide precursor solution which comprises a polyimide precursor and a solvent wherein the polyimide precursor and the solvent are not solated strongly. A process for the production of the polyimide precursor solution, as well as moldings and coatings obtained from the solution. The polyimide precursor solution of the present invention has excellent storage stability, and the solvent can be removed easily at the time of the production of moldings or coatings. According to the process of the present invention, the polyimide precursor solution can be produced easily using simple apparatus and an inexpensive solvent(s) having low toxicity. The polyimide molding obtained from the polyimide precursor solution has excellent uniformity and no residual solvent. The polyimide coating obtained from the polyimide precursor solution has excellent uniformity, no residual solvent and excellent adhesiveness to a base material.
