ADHESIVE FILM FOR POLARIZING PLATE, POLARIZING PLATE INCLUDING THE SAME AND OPTICAL DISPLAY INCLUDING THE SAME |
| 摘要 |
An adhesive film for polarizing plates, a polarizing plate including the same, and an optical display including the same are provided. An adhesive film for polarizing plates is formed of an adhesive composition for polarizing plates, which includes a non-carboxylic acid (meth)acrylic copolymer, an isocyanate curing agent, and an epoxy curing agent, wherein the adhesive film has a modulus at 85° C. of about 0.1 MPa to about 0.8 MPa and a modulus ratio of about 3 or less, as calculated by the equation, Modulus ratio=G′(25° C.)/G′(85° C.), where G′(25° C.) is modulus (unit: MPa) at 25° C. of an adhesive film and G′(85° C.) is modulus (unit: MPa) at 85° C. of the adhesive film. |

1. An adhesive film for polarizing plates, the adhesive film being formed of an adhesive composition comprising: a non-carboxylic acid (meth)acrylic copolymer; an isocyanate curing agent; and an epoxy curing agent,
wherein the adhesive film has a modulus at 85° C. of about 0.1 MPa to about 0.8 MPa and a modulus ratio of 3 or less, as calculated by Equation 1:
Modulus ratio=G′(25° C.)/G′(85° C.), where G′(25° C.) is modulus (unit: MPa) at 25° C. of the adhesive film and G′(85° C.) is modulus (unit: MPa) at 85° C. of the adhesive film. |
