Beschreibung
Zusammenfassung:	Provided is a polyimide resin having constituent units A derived from tetracarboxylic dianhydride and constituent units B derived from diamine. The constituent units A include constituent units (A-1) derived from a compound represented by formula (a-1), and constituent units (A-2) derived from a compound represented by formula (a-2). Constituent units B include constituent units (B-1) derived from a compound represented by formula (b-1), and the ratio of constituent units (B-1) in constituent unit B is at least 70 mol%. Also provided are a polyimide varnish and a polyimide film containing said polyimide resin.
