Abstract (en)
[origin: WO0244291A2] To provide a coating composition of a soluble aromatic polyimide having good heat resistance and mechanical strength. As a soluble polyimide, a compound of the formula (I) in which R's represent independently from one another H, halogen, an alkyl group or an alkoxy group, or a substituted or unsubstituted phenyl group; A is a tetravalent aromatic group or a group of the formula (II) in which B is a covalent bond, a >C(R<2>)2 group, a carbonyl group, 0, S, a >SO2, group, a >Si (CH3)2 group, a >Si(C2H5)2 group, a >NR<3> group or a bifunctional ether group in which R<2> is a hydrogen atom or -C(R<4>)3, R<3> is H, an alkyl group or an aryl group, and R<4> is H, F or Cl; Ar is an aromatic nucleus or a group of the formula (III) in which Ar and B are the same as defined above, and each p is an integer of 0 to 10; m is an integer of 1 to 10 is used. The polyimide has a weight average molecular weight of 150,000 to 1,000,000.
