Patent ID: 8492506

Claim:
A polyimide precursor resin composition, comprising a polyimide-imide (A) containing a diamine monomer unit represented by the following formula (1) and a poly amic acid (B) containing at least one kind of monomer unit selected from the group consisting of tetracarboxylic acid monomer units represented by the following formulae (2p) to (2r), wherein the haze of the film having a thickness of 40 μm obtained by imidation of the polyimide precursor resin composition is 4% or less; wherein the polyamic acid (B) is obtained by reacting a diamine component with at least one kind of monomer unit selected from the group consisting of tetracarboxylic acid monomer units represented by the following formulae (2p) to (2r) in the presence of the polyamide-imide (A) at 60-80° C.; wherein R represents an alkylene group having 1 to 5 carbon atoms;
