This polyimine is a reaction product of a dialdehyde and a diamine, said dialdehyde being an aromatic dialdehyde that does not have a hydroxyl group, and said diamine including an aromatic diamine that has an electron withdrawing group. This polyimine-imide is a reaction product of a dialdehyde, a diamine, and an acid anhydride, said dialdehyde being an aromatic dialdehyde that does not have a hydroxyl group, said diamine including an aromatic diamine that has an electron withdrawing group, and said acid anhydride including at least one type of acid anhydride selected from the group consisting of aromatic acid anhydrides and alicyclic acid anhydrides. |
