A polyimide adhesive composition is a reaction product of polyamic acid and bismaleimide (I) modified by barbituric acid (II) or the derivatives thereof. Once the present composition is directly coated onto copper foil, the bonding force is greatly improved as compared to compositions without (II) or (I) and (II). Therefore, the adhesive normally used in the manufacture of flexible printed circuits boards and tape automated bonding (TAB) is no longer necessary.
