NOVELTY - Manufacture of surface protection film involves preparing adhesive composition containing (meth)acrylic acid ester copolymer, isocyanate-type crosslinking agent, 0.001-0.009 parts mass reaction accelerator and 0.01-1 parts mass reaction retarder, with respect to 100 parts mass (meth)acrylic acid ester copolymer, coating adhesive composition on base material (2) containing polyester film, heating the base material in which the adhesive composition is coated, volatilization-removing reaction retarder from the adhesive composition, and promoting crosslinking adhesive composition.    USE - Manufacture of surface protection film. Uses include but are not limited to touchscreen, liquid crystal display device, organic electroluminescent apparatus, plasma display panel and solar cell.    ADVANTAGE - The method enables efficient manufacture of surface protection film having excellent adhesiveness with respect to adhesive layer and base material, with high productivity and yield, and suppresses deformation of adhesive composition and unevenness formed in the substrate surface.    DETAILED DESCRIPTION - Manufacture of surface protection film involves preparing adhesive composition containing (meth)acrylic acid ester copolymer including 0.5-10 %mass structural unit derived from monomer which has hydroxyl group, or structural unit derived from monomer which has hydroxyl group and structural unit derived from monomer which has carboxyl group, and having molecular weight less than 800000, isocyanate-type crosslinking agent, 0.001-0.009 parts mass reaction accelerator and 0.01-1 parts mass reaction retarder, with respect to 100 parts mass (meth)acrylic acid ester copolymer, coating adhesive composition on base material containing polyester film, heating the base material in which the adhesive composition is coated, volatilization-removing reaction retarder from the adhesive composition, and promoting crosslinking adhesive composition.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining manufacture of surface protection film.    Base material (2)    Peeling film (4)    Laminate (5)    Heating unit (6)    Winding apparatus (7)
