PURPOSE: An adhesive composition for electronic paper is provided to obtain a contrast range of 5 or more after curing by increasing the ion content in the adhesive composition, thereby obtaining excellent electric operation and color reproducibility. CONSTITUTION: An adhesive composition for electronic paper satisfies a condition of formula 1: X=100-5,000ppm. In the formula 1, X is the ion content of a cured material of the adhesive composition and represents the total content of anions and cations. The adhesive composition comprises: a monomer mixture for forming an emulsion copolymer resin which includes alkyl(meth)acrylic acid ester monomer; an emulsifier; and a neutralizer. The emulsifier and/or the neutralizer are ion-based. An adhesive film for the electronic paper is obtained by applying the adhesive composition onto an adhesive film or sheet, and forming an adhesive layer(100). |
