Abstract:
This hard coating film (10) sequentially comprises, on a transparent film (1), a hard coating layer (3) and a top coating layer (5); and the top coating layer is positioned on the outermost surface. The hard coating layer has a thickness of 0.5 µm to 100 µm; and the top coating layer has a thickness of 2 µm to 20 µm. The hard coating layer is a cured product of a hard coating composition that contains a polyorganosiloxane compound containing an alicyclic epoxy group and a cationic photopolymerization initiator. The top coating layer is a cured product of a top coating composition that contains a multifunctional (meth)acrylate having three or more (meth)acryloyl groups in each molecule and a radical photopolymerization initiator. It is preferable that the top coating composition additionally contains a fluorine compound that comprises a fluorine atom and a functional group having a radically polymerizable double bond in each molecule.
