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 thermosetting adhesive composition comprising specified components has been laminated, curing said composition, and then peeling off the sheet. CONSTITUTION:A thermosetting adhesive composition comprising a polymerizable compound having one or more polymerizable unsaturated groups in its molecule, a substrate polymer or oligomer and a thermal polymerization initiator is applied onto the surface of a self-supporting sheet (or film). After the composite sheet on which the layer of said thermosetting adhesive composition has been formed is laminated through said adhesive layer onto the surface of a body to be coated, e.g. a plate body, said adhesive layer is cured by heating it. Thereafter, said 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.
