Ink composition, window using the same, and manufacturing method of window using the same

A manufacturing method of a window, the method comprising:

• providing a base substrate comprising a flat area and at least one bent area adjacent the flat area;
• printing an ink composition on a face of the base substrate;
• and
• curing the printed ink composition,
• wherein the ink composition comprises:
• an acrylic resin comprising a polymerization of product of a first monomer having a hydroxyl group, a second monomer having an epoxy group, a third monomer having an acrylate group, and a fourth monomer having a substituted or unsubstituted phenyl group;
• an epoxy resin;
• a first curing agent having an isocyanate group;
• and
• a second curing agent having an amine group,
• wherein a solid content of the epoxy resin is present in the ink composition in about 12.5 parts by weight to about 25 parts by weight based on 100 parts by weight (solid content) of the acrylic resin.

A window comprising:

• a base substrate comprising a flat area and at least one bent area adjacent the flat area;
• and
• a printed layer disposed on one face of the base substrate and formed with an ink composition,
• wherein the cured ink composition comprises:
• an acrylic resin comprising a polymerization product of a first monomer having a hydroxyl group, a second monomer having an epoxy group, a third monomer having an acrylate group, and a fourth monomer having a substituted or unsubstituted phenyl group;
• a first curing agent having an isocyanate group;
• and
• a second curing agent having an amine group,
• wherein the ink composition includes:
• from about 10 moles to about 30 moles of the first monomer;
• from about 10 moles to about 20 moles of the second monomer;
• from about 20 moles to about 35 moles of the third monomer;
• and from about 20 moles to about 35 moles of the fourth monomer.
