PURPOSE:To easily form a layer capable of protecting the surface of a body to be coated from before to after processing, by processing the body to be coated onto which a sheet coated with a photocuring acryl adhesive composition comprising specified components has been laminated, curing said composition, and then peeling off the sheet. CONSTITUTION:A photocuring adhesive composition comprising a) an acrylic copolymer of 3,000-50,000 in average molecular weight having one or more (meth)acryloyl groups and a functional group contributive to cross linking in its molecule, b) a cross liking agent capable of reacting with the functional group contributive to cross linking in said copolymer and a photosensitizer is applied onto a self-supporting sheet (or film). After the composite sheet on which said adhesive layer has been formed is laminated through the adhesive layer onto the surface of a body to be coated, the adhesive layer is cured by light irradiation. Then, the self-supporting sheet only is peeled off to form a surface protective layer comprising a polymerizedly cured product on the surface of the body to be coated. According to this method, the damage of the surface of the body to be coated before and during processing can be inhibited by the application of said composite sheet, and the surface after being processed can be protected by the surface protective layer.
