摘要： A high hardness flexible hard coating film is disclosed. The high hardness flexible hard coating film comprises a substrate film and a hard coating layer. The hard coating layer comprises a (meth)acrylate binder and reactive silica nanoparticles, wherein the reactive silica nanoparticles comprise reactive (meth)acrylate modified silica nanoparticles and reactive (meth)acrylate-polyhedral oligomeric silsesquioxane (POSS) modified silica nanoparticles. The high hardness flexible hard coating film will not crack or fracture under an dynamic inward folding test for performing 180° bend testing at a radius of 1 mm with 2×105 times, and the pencil hardness (JIS K 5400) thereof is 6H or more.
