| abstract |
The present invention provides a hard coating film having excellent flexibility that cannot be obtained by existing coating compositions and at the same time having a high surface hardness of 9H or more. The present invention relates to a hard coating film using a siloxane resin composition containing an epoxy group and a method for producing the hard coating film, and more particularly, to a special heat treatment after cation polymerization of a siloxane resin composition containing an epoxy group. A method for producing a hard coating film using a polymerization method. A method for producing a hard coating cured product, wherein the composition contains a siloxane resin containing an epoxy group and a cationic initiator, and further contains a reactive monomer containing an alicyclic epoxy group, a glycidyl group or an oxetane group.
