(A) 40-80 mass% of butyl acrylate units, 1-15 mass% of styrene units, 1-30 mass% of methyl methacrylate units, 1-30 mass% of methyl acrylate units, hydroxyl group containing vinylic monomer units 1-10 An acrylate copolymer composed of mass% and 0.1-1 mass% of carboxyl group-containing vinyl monomer units, having a weight average molecular weight (Mw) of 300,000 to 1 million, and a molecular weight distribution (Mw / Mn) of 3.0 or less; B) It is a re-peelable process film formed by forming the adhesive layer which consists of an isocyanate type crosslinking agent on one side of a base film. In this process film, when the adherend is a base sheet, the contamination on the side of the base sheet after peeling is suppressed, and the adhesive force with the adhesive sheet applied to the peeling surface after peeling is sufficiently high, and the adherend has a high temperature near 260 ° C. Applicable also in the case of exposed glass parts. |
