Abstract: The present invention relates to a siloxane hard resin including alicyclic epoxy siloxane alone or a reactive monomer, which is prepared by condensation reaction of alkoxysilanes, and has a weight average molecular weight in the range of 1000 to 4000 and a molecular weight distribution of PDI 1.05 to 1.4. A siloxane hard cured article produced by photo- or thermal polymerization has high hardness by compact crosslinking of siloxane molecules having different molecular weights.

Abstract: The present disclosure relates to a hard-coating cured material which contains a siloxane resin component including an epoxy group and a preparing method of the hard-coating cured material. Especially, by using a special polymerization method like a cationic polymerization and a moisture-heat treatment, it is possible to provide a hard-coating film having both superior flexibility and high surface hardness that cannot be obtained from conventional coating compositions.
