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.
