The ink composition comprises 100 parts by weight of an organic solvent-soluble polyimide block copolymer(s), and 1 to 100 parts by weight of a photoacid generator(s). The polyimide block copolymer(s) and the photoacid generator(s) are dissolved in an organic solvent. The polyimide block copolymer(s) contain(s) in its molecular skeleton a diamine having a siloxane bond, and an aromatic diamine having a hydroxyl group(s) and/or carboxyl group(s) at ortho-position with respect to an amino group.
