Abstract
There is disclosed an overlaminating adhesive film comprising a transparent film, an adhesive layer and a release material successively laminated in this order, wherein said release material has a surface contacting with the adhesive layer, said surface having a centerline average surface roughness of 0.5 μm or lower; an adhesive forming said adhesive layer has a pH of 7.2 to 8.5 in a solution state before applied, and is an acrylic emulsion-type adhesive having an average particle size of 200 nm or smaller; and a monomer component used for production of said adhesive includes an alkoxysilane group-containing unsaturated monomer in which each alkoxy group has 1 to 4 carbon atoms, but includes no hydroxy-containing unsaturated monomer. The overlaminating adhesive film of the present invention exhibits a good water resistance and is free from deterioration in its transparency due to lifting or bubbles when laminated on an adherend.
