In a first aspect, an article includes an inorganic substrate and a polymer film layer. The inorganic substrate includes a material including a ceramic, a glass, a glass-ceramic or a mixture thereof. The material includes a metal cation selected from the group consisting of silicon, aluminum, titanium, zirconium, tantalum, niobium and mixtures thereof and oxygen. The polymer film layer includes a polymer including an imide group. From an interface where the inorganic substrate contacts the polymer film layer, a line-profile of a CNO− signal from negative secondary ion mass spectroscopy decreases as it moves away from the interface and into the bulk of the polymer film layer.

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.

Disclosed is an actinic radiation curable (meth)acrylic composition for use in hardcoats for optical displays containing one or more multifunctional (meth)acrylate monomers, one or more Si-containing (meth)acrylate monomers, one or more UV radical initiators, one or more monomers to improve surface cure, nanoparticles, and one or more organic solvents. Coated hardcoat articles made from this composition exhibit improved properties for use in display applications.
