Imide is acidic as its H+ can be released. The two strongly electronegative carbonyl O are capable of withdrawing the unshared pair of electrons on N as well as the electrons making the N-H bond. This weakens the N-H bond. After the H+ is released, the anion is stabilised by resonance.
If a proton on N between two C=O's is removed by a base, one can draw two resonance structures, one involving each C=O, to stabilize the resulting anion. However, with an amide, there is only one C=O and when the H is removed, only one resonance structure can be drawn. As a result, the amide H is less acidic than the imide H.

SO2 is acidic. When dissolved in water, it forms sulfurous acid, which can donate a hydrogen ion, making the solution acidic.
Coffee is acidic.
Yes, coffee is acidic.

However, with an amide, there is only one C=O and when the H is removed, only one resonance structure can be drawn. As a result, the amide H is less acidic than the imide H.
Imides are more acidic than amides because the hydrogen atom in imides is present on a nitrogen atom that is more electronegative than the oxygen atom in amides. This greater electronegativity leads to a more stable conjugate base after deprotonation, making the imide more acidic.
An azimine is an azo imide.
An amine imide is any of a class of organic compounds formally derived from an amine and a nitrene - R3N+-N-R.
The Global Polyamide-imide Resin Market growing at a CAGR of 6.2%, and it is expected to reach USD 0.91 billion by 2029, over the forecast period 2023-2029.
