Polyimine precursor, polyimine, varnish, polyimide film and substrate |
| abstract |
The present invention relates to a polyimine precursor comprising a repeating unit represented by the following chemical formula (1), characterized in that at least two kinds of A are the following chemical formulas (2-1) and (2-2) a repeating unit represented by the chemical formula (1) represented by any one of (3) or (4), a linear thermal expansion coefficient of 50 to 200 ° C of the polyimine obtained from the polyimide precursor The transmittance is 50 ppm/K or less, and the transmittance at a wavelength of 400 nm at a thickness of 10 μm of the polyimide film is 75% or more. □ (wherein A is excluded from the divalent group of the amine group from the aromatic diamine or the aliphatic diamine, and each of X1 and X2 is independently hydrogen, an alkyl group having 1 to 6 carbon atoms, or a carbon number of 3 to 9 Alkyl group.) □□□□ |
