Abstract
An adhesive film for a reflection sheet and a reflection sheet using the adhesive film is provided. The adhesive film comprises a plastic base film having a heat shrinkage of −0.1 to 0.5% at 150° C. in machine and transverse directions; an adhesive layer formed on one side of the base film by applying an adhesive composition; and an anchor coating layer formed on the other side of the base film, opposite to the side on which the adhesive layer is formed. The adhesive film for a reflection sheet according to the present invention is manufactured by applying an adhesive composition on a plastic base film where heat shrinkage is controlled. Thus, the adhesive film has superior dimensional stability at a high temperature and excellent workability in a post process for laminating a reflection layer. Partial detachment does not occur when an adhesive layer is detached from an adherent, and stable physical properties can be achieved.
