Abstract:
1. A method of adhering a pressure-sensitive adhesive sheet for vehicle coatings containing a surface control agent, comprising the step of adhering the pressure-sensitive adhesive sheet onto coated surface of the vehicle coatings, characterized in that the difference (absolute value) between the solubility parameter (SP value) of a pressure-sensitive adhesive layer (X) formed on the side of the pressure-sensitive adhesive sheet in contact with the vehicle coating and the solubility parameter (SP value) of the surface control agent contained in the vehicle coating is 0.6 (cal/cm 3 ) 1/2 or less, wherein the pressure-sensitive adhesive layer (X) is formed by curing an acrylic adhesive composition containing a vinyl monomer containing an alkyl (meth)acrylate (al) having an alkyl group containing 2 to 14 carbon atoms as the principal component or a partial polymer thereof (a), a photopolymerization initiator b and a multifunctional (meth)acrylate (c) by irradiation with active energy ray, wherein the alkyl (meth)acrylate (al) is contained in an amount of 60 wt % or more with respect to the sum of all monomer components of the vinyl monomer.
