Abstract: PURPOSE: An acrylic adhesive is provided to use for an optical film, and to reduce the difference of a refractive index with an optical film by improving refractive index. CONSTITUTION: An acrylic adhesive comprises 2-ethylhexylacrylate, 2-ethylhexylacrylate, acrylic acid, and zirconium carboxyethylacrylate in chemical formula 1 or 2-phenoxyethylacrylate in chemical formula 2. The adhesive manufactured by mixing 80-98 weight% of 2-ethylhexylacrylat, 1-10 weight% of acrylic acid, and 0.1-1.5 weight% of zirconium carboxyethylacrylate on the basis of total weight of a monomer, and through a solvent-polymerization. The adhesive is manufactured by using methyl arizidine derivatives as a hardener.
