Claim:
1. A hard-coating resin composition consisting essentially of a siloxane resin including an alicyclic epoxy group, wherein the siloxane resin has a weight-average molecular weight in the range of from 1,000 to 4,000 and a molecular weight distribution of PDI ranging from 1.05 to 1.4, wherein an epoxy equivalent of the siloxane resin is in the range of from 0.35 to 0.6 mol/100 g, and wherein the siloxane resin is prepared, in the presence of water and a catalyst, by hydrolysis and condensation of (i) an alkoxysilane alone represented by the following Chemical Formula 1 including an alicyclic epoxy group and an alkoxy group, or (ii) an alkoxysilane represented by the following Chemical Formula 1 including an alicyclic epoxy group and one or more selected from the group consisting of tetramethoxysilane, tetraethoxysilane, methyltrimethoxysilane, methyltriethoxysilane, methyltripropoxysilane, dimethyldimethoxysilane, dimethyldiethoxysilane, phenyltrimethoxysilane, phenyltriethoxysilane, triphenylmethoxysilane, triphenylethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, vinyltrimethoxysilane, vinyltriethoxysilane, vinyltripropoxysilane, N-(3-acryloxy-2-hydroxypropyl)-3-aminopropyltrimethoxysilane, N-(3-acryloxy-2-hydroxypropyl)-3-aminopropyltriethoxysilane, N-(3-acryloxy-2-hydroxypropyl)-3-aminopropyltripropoxysilane, 3-acryloxypropylmethylbis(trimethoxy)silane, 3-acryloxypropyltrimethoxysilane, 3-acryloxypropyltriethoxysilane, 3-acryloxypropyltripropoxysilane, 3-(meth)acryloxypropyltrimethoxysilane, 3-(meth)acryloxypropyltriethoxysilane, 3-(meth)acryloxypropyltripropoxysilane, N-(2-aminoethyl)-3-aminopropyltrimethoxysilane, N-(2-aminoethyl)-3-aminopropyltriethoxysilane, 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, chloropropyltrimethoxysilane, chloropropyltriethoxysilane, and heptadecafluorodecyltrimethoxysilane: wherein, R R n is an integer of from 1 to 3.
