Abstract:
Provided are a dope solution for preparing a polarizing plate protective film by a solution casting method using an acrylic polymer with high thermal resistance and high molecular weight, and a polarizing plate protective film using the same.
The polarizing plate protective film using the dope solution according to the present invention has excellent optical properties, high tensile strength, low hygroscopic properties, and high thermal resistance, and thus, has the effects of excellent dimensional stability, and excellent adhesion with a polyvinyl alcohol film.
The polarizing plate protective film using the dope solution according to the present invention has excellent optical properties, high tensile strength, low hygroscopic properties, and high thermal resistance, and thus, has the effects of excellent dimensional stability, and excellent adhesion with a polyvinyl alcohol film.
