Document Type and Number:
WIPO Patent Application WO/2013/161970
Kind Code:
A1
Abstract:
The present invention relates to a polyamic acid solution composition, which is obtained by reacting a tetracarboxylic acid component comprising at least 50 mol% of a fluorine atom-containing tetracarboxylic dianhydride and a diamine component comprising at least 50 mol% of a fluorine atom-containing diamine in a solvent and adding to the resulting polyamic acid solution a colloidal solution of colloidal silica dispersed in an organic solvent such that the amount of the silica is 1 to 100 parts by mass per a total of 100 parts by mass of the tetracarboxylic acid component and the diamine component.
