Abstract: The present invention relates to an adhesive composition for adhesion of a polarizing film and a protecting film, a preparation method of the polarizer using the adhesive composition and a polarizer produced by the method. The adhesive composition of the present invention is a photocurable adhesive composition composed of 30-70 weight part of (metha)acrylate monomer, 25-65 weight part of acrylate oligomer, 4-10 weight part of a photoinitiator, and 0-3 weight part of an additional additive. And, the polarizer prepared by using the same has excellent flexibility, elasticity, impact resistance, adhesive strength and durability, resulting in the increase of strength and reliability as a polarizer. The preparation method of a polarizer of the present invention using the photocurable adhesive composition does not need heating and pressing processes, making the manufacturing line simple and thereby reducing costs for facilities.
