摘要

PROBLEM TO BE SOLVED: To provide a composition capable of obtaining a coated film having advantageous viscosity stability and advantageous fluidity during the processing, having advantageous shape retentivity after the processing, having advantageous drying property in a temperature range in which a conductive layer is not degraded during the drying, and being excellent in the adhesion strength with a metal-polyimide, flame retardancy, heat resistance, flexibility, mechanical physical property, and chemicals resistance after the drying.

SOLUTION: This composition is a composition comprising (A) a polyimide and (B) a solvent mixture of two or more types of solvents, in which the compatibilization parameter of the solvent mixture of two or more types of solvents is 9 to 14.
