Polarizer protective film comprising a cured resin
The present invention relates to a polarizer protective film comprising a cured resin and exhibiting high hardness and excellent properties.
1. A polarizer protective film, including a cured resin of a composition comprising a multifunctional acrylate monomer, an acrylate oligomer having an elongation of 5 to 200%, and an acrylate elastic polymer;
wherein the acrylate elastic polymer includes one or more poly-rotaxane, and wherein the poly-rotaxane includes a macrocyclic compound combined with a lactone compound including an acrylate moiety at the end; a linear molecule passing though the macrocyclic compound; and
stopper groups which are connected to both ends of the linear molecule and prevent the macrocyclic compound from leaving,
wherein the acrylate oligomer having the elongation of 5 to 200% is modified with one or more selected from the group consisting of propylene oxide and caprolactone, and
wherein the composition is solvent free.
2. The polarizer protective film according to claim 1 , wherein the composition comprises 20 to 70 parts by weight of the multifunctional acrylate monomer, 20 to 70 parts by weight of the acrylate oligomer having the elongation of 5 to 200%, and 1 to 50 parts by weight of the acrylate elastic polymer, when the total weight of the cured resin is 100 parts by weight.
3. The polarizer protective film according to claim 1 , wherein the acrylate elastic polymer has an elongation of 5 to 200%.
