POLYIMIDE PRECURSOR SOLUTION AND POLYIMIDE FILM PRODUCED BY USING THE SAME |
| abstract |
The present invention relates to a process for producing a polyimide precursor by using an amide-based organic solvent having a positive logarithm (Log P) and a density of 1 g / cm 3 or less to alleviate the interaction between the polyimide precursor polyamic acid and the organic solvent, The viscosity of the precursor solution can be lowered, and a polyimide precursor solution having a high solid content and a low viscosity can be obtained. |
