摘要： Provided is a hard coating film. The hard coating film includes a base layer and a hard coating layer disposed on the base layer and having a pencil hardness of 4H or higher. A surface elongation at break of the hard coating film falls within a predetermined range, as measured by a certain method. The hard coating film shows excellent durability under high-temperature/high-humidity conditions, has no microcracks formed after repeated folding, and shows excellent pencil hardness.

摘要： Provided is a hard coating film including a polyamideimide substrate layer and a hard coating layer, each of which has a predetermined refractive index, with a difference in the refractive index between those layers being 0.05. The substrate layer has a tensile modulus of 3 to 7 GPa, at a thickness of 80 μm, as measured according to ASTM D111. The present invention relates to a hard coating film having improved mechanical and optical properties.
