<p>An object of the present invention is to provide a polyimide precursor composition solution that (i) uses no siloxane diamine, (ii) is curable at low temperature (not more than 250° C.) and (iii) has low viscosity regardless of its high concentration, and a photosensitive resin composition, photosensitive resin film, a thermosetting resin composition, a polyimide insulating film, and a printed wiring board with an insulating film, each of which has good physical properties and is obtained by use of the polyimide precursor composition solution. The foregoing object is attained by using a polyimide precursor composition solution which includes at least a (A) urethane imide oligomer having a terminal carboxylic acid group and a (B) diamino compound and/or isocyanate compound.</p> |
