PURPOSE: An adhesive improver is provided to improve adhesion with other layers, and to provide a retardation film with excellent adhesion between layers. CONSTITUTION: An adhesive improver accommodates an isocyanate group by reaction of a polymer with a repeating unit represented by chemical formula 1, and polyfunctional isocyanate. In chemical formula 1, each of R1 and R2 is independently hydrogen, methyl group, or cyano group; each of R3, R4, and R5 is independently halogen-substitutable C0-6 alkylene group, and can include a ketone group, ester group, or thiol group; and A is halogen, C3-10 cycloalkyl group, aryl group, phenyl group, benzyl group, or C1-8 alkoxy group. |
