Document Type and Number:
WIPO Patent Application WO/2014/046064
Kind Code:
A1
Abstract:
The invention pertains to a polyimide precursor containing at least one repeating unit represented by chemical formula (5) and/or at least one repeating unit represented by chemical formula (6). (In the formula, A3 is a bivalent group obtained by removing an amino group from an aromatic diamine or aliphatic diamine, and X3 and Y3 are each independently hydrogen, an alkyl group having 1-6 carbon atoms, or an alkylsilyl group having 3-9 carbon atoms.) (In the formula, A3 is a bivalent group obtained by removing an amino group from an aromatic diamine or aliphatic diamine, and X4 and Y4 are each independently hydrogen, an alkyl group having 1-6 carbon atoms, or an alkylsilyl group having 3-9 carbon atoms.)
