There is provided a modified polyimide comprising a terminal group of the following formula (1) of the present invention and a curing composition containing the modified polyimide. The modified polyimide according to the present invention can provide a highly transparent and colorless transparent polyimide film by suppressing lowering of transmittance and color change due to curing. In particular, it is possible to provide a polyimide film with high transparency, , Insulating films for multilayer printed boards, insulating films for OLEDs, protective films for thin film transistors of liquid crystal display devices, and the like. [Chemical Formula 1] In the above formula, D is a thermosetting or photocurable functional group, R is a divalent or higher-valent organic group, and n is an integer of 1 or more. |
