Document Type and Number:
WIPO Patent Application WO/2017/191830
Kind Code:
A1
Abstract:
The present invention relates to the following: a polyimide resin having a constituent unit A derived from a tetracarboxylic acid dianhydride and a constituent unit B derived from a diamine, wherein the constituent unit A includes a constituent unit (A-1) derived from 4,4'-(hexafluoroisopropylidene)diphthalic anhydride and the constituent unit B includes a constituent unit derived from an aliphatic diamine; a polyimide resin composition including the polyimide resin and inorganic microparticles; and a polyimide film including the polyimide resin or the polyimide resin composition. The present invention provides: a polyimide resin that makes it possible to form a film having heat resistance, colorless transparency, and low water absorbency; a polyimide resin composition; and a polyimide film.
