  In a first aspect, a polyimide film includes a dianhydride and a diamine. The dianhydride, the diamine or both the dianhydride and the diamine include an alicyclic monomer, an aliphatic monomer or both an alicyclic monomer and an aliphatic monomer. The polyimide film has a tensile modulus of 5.5 GPa or more, a b* of 1.4 or less and a yellowness index of 2.25 or less for a film thickness of 50 μm. In a second aspect, an electronic device includes the polyimide film of the first aspect.

  In a first aspect, a coating solution includes a soluble polymer and a crosslinking precursor. The soluble polymer includes an imide group. The crosslinking precursor includes a first amine group that is either reactive or passivated towards crosslinking and one or more additional amine groups, wherein the one or more additional amine groups has been passivated towards crosslinking such that the crosslinking precursor can be chemically converted, thermally converted, photo-converted or dissociated to form at least two reactive amines. In a second aspect, a process for forming a polymer film includes: (a) casting a coating solution, (b) activating the crosslinking precursor using an external stimulus to form at least two reactive amines and crosslink the polymer, and (c) drying the polymer film. The coating solution includes a soluble polymer, including an imide group, and a crosslinking precursor.
