| description | The object of the present invention is to provide a coating composition capable of forming a polyimide resin having less coloration and excellent mechanical properties, a method for producing the coating composition, and a method for producing a polyimide resin using the coating composition. The solution of the present invention includes a coating composition of polyamic acid (A) and a solvent (S), wherein the polyamic acid (A) includes polymers of alicyclic tetracarboxylic dianhydride (A1-1), a small amount of aromatic tetracarboxylic acid dianhydride (A1-2) and aromatic diamine compound (A2). |
