Hard coating composition, hard coating film obtained therefrom, laminate including hard coating film, method of forming hard coating film, and article including hard coating film

A laminate comprising:

• a substrate;
• and
• a single hard coating film disposed on the substrate, the single hard coating film comprising a cured (meth)acrylate-based resin, wherein the single hard coating film has an average water contact angle of 33.5° to 40° and a pencil hardness of 6H or greater at a 1 kilogram load,
• wherein the cured (meth)acrylate-based resin comprises a mixture of three or more multifunctional monomer units and a monofunctional monomer unit with a hydrophilic group,
• wherein the mixture of the three or more multifunctional monomer units includes monomer units derived from a tetra(meth)acrylate monomer, a tri(meth)acrylate monomer, and a di(meth)acrylate monomer,
• wherein the mixture of the three or more multifunctional monomer units comprise pentaerythritol tetra(meth)acrylate, ethoxylated ditrimethylolpropane tetra(meth)acrylate, pentaerythritol tri(meth)acrylate, ethoxylated trimethylolpropane tri(meth)acrylate, ethoxylated ditrimethylolpropane tri(meth)acrylate, ethoxylated bisphenol A di(meth)acrylate, or ethoxylated trimethylolpropane di(meth)acrylate, and
• the mixture of the three or more multifunctional monomer units comprises a weight ratio of the tetra(meth)acrylate monomer, the tri(meth)acrylate monomer, and the di(meth)acrylate monomer is 0.2-1.8:2.8-4.8:1,
• wherein a weight ratio of the three or more multifunctional monomer units to the monofunctional monomer unit with the hydrophilic group is 1:1 to 1.5:1,
• wherein the monofunctional unit with the hydrophilic group comprises a monomer unit derived from methoxy polyethylene glycol (meth)acrylate,
• wherein the monomer unit derived from the monofunctional monomer unit with the hydrophilic group in the cured (meth)acrylate-based resin is 29 weight percent to 45 weight percent, based on the total weight of monomer units of the single hard coating film, and
• the mixture of the three or more multifunctional monomer units in the cured (meth)acrylate-based resin is 53 weight percent to 59 weight percent, based on the total weight of monomer units of the single hard coating film.
