Abstract: A method of producing a laminate including a laminated structure of a pressure-sensitive adhesive sheet, a reinforcing agent layer, and an adherend, the laminate being capable of expressing high impact resistance even when the thickness of the reinforcing agent layer is small, and/or being capable of expressing a high adhesive strength. The method of producing a laminate includes: a step (I) of applying an aqueous paint containing a reinforcing agent and an aqueous medium to a surface of the adherend to form the reinforcing agent layer; and a step (II) of bonding the pressure-sensitive adhesive sheet to a surface of the reinforcing agent layer thus formed, the aqueous paint containing, in 100 parts by weight thereof, 6 parts by weight to 98 parts by weight of an alcohol.

Abstract: The present invention provides a method of stripping multiple plies of a pressure-sensitive adhesive layer, capable of easily separating and dismantling the joint portion in a short time, without affecting the adherend involved. The stripping method of the present invention strips the multiple plies of a pressure-sensitive adhesive layer, including a pressure-sensitive adhesive body having at least a pressure-sensitive adhesive layer containing heat-expandable fine particles and an adherend, the pressure-sensitive adhesive body and the adherend being laminated on each other, and the multiple plies of a pressure-sensitive adhesive layer contain a coloring matter component, and the pressure-sensitive adhesive body and the adherend are stripped from each other, by irradiating the coloring matter with a laser light beam having a wavelength coinciding with the absorption wavelength of the coloring matter and by expanding the heat-expandable fine particles with the aid of the heat thus generated.
