US Patent 7776436 Hardcoat film

A hardcoat for a plastic substrate film is provided which has good suitability for printing and satisfactory hardness, can prevent influence of the deformation of a plastic substrate film from extending to the hardcoat, and is resistant to cracking and peeling. The hardcoat is produced from a coating component containing one or more organic components having a polymerizable functional group and an inorganic filler, at least one of the organic components being free from a hydrogen bond-forming group. In the hard coat, the content of the inorganic filler in the surface of the hardcoat is higher than that in the interior of the hardcoat. The hardcoat can be applied to antireflection films and hologram labels.
