Abstract
Provided are an optical display device protecting film and an optical display device comprising the same, the optical display device protecting film comprising: a first substrate layer; and a hard coating layer formed on the first substrate layer, wherein the substrate layer is made of a thermoplastic polyurethane film, and the first substrate layer has a thickness of 100 μm to 200 μm and has a Shore hardness of 95 A to 98 A.
Claims24
A protective film for optical displays, comprising:
- a first base layer;
- and a hard coating layer formed on the first base layer,
- wherein the first base layer is formed of a thermoplastic polyurethane and the first base layer has a thickness of 100 μm or more to 200 μm or less and a Shore hardness of 95 A to 98 A.
A protective film for optical displays, comprising:
- a first base layer;
- and a hard coating layer formed on the first base layer,
- wherein the hard coating layer is formed of a hard coating composition comprising a first urethane (meth)acrylate oligomer, a second urethane (meth)acrylate oligomer, a (meth)acrylate monomer, zirconia particles, an initiator, a silicon-based additive, and a fluorine-based additive,
- wherein the first urethane (meth)acrylate oligomer has different elongation from the second urethane (meth)acrylate oligomer,
- wherein the first urethane (meth)acrylate oligomer is present in an amount of about 10 parts by weight to about 50 parts by weight and the second urethane (meth)acrylate oligomer is present in an amount of about 40 parts by weight to about 80 parts by weight, of the total amount of 100 parts by weights of the first urethane (meth)acrylate oligomer, the second urethane (meth)acrylate oligomer, the (meth)acrylate monomer, and the zirconia particles.
