Claims20
A method of preparing a hard coating film, comprising the steps of:
- applying a hard coating composition onto both sides of a supporting substrate, the hard coating composition comprising a binder including a tri- to hexa-functional acrylate-based monomer, inorganic particles and a photoinitiator;
- and
- irradiating the applied hard coating composition with ultraviolet to simultaneously photocure the hard coating composition, thus forming a hard coating layer.
