Abstract

The present invention is to provide a method for producing a laminate having excellent adhesion properties. An embodiment of the present invention is a method for producing a laminate, the method including: a step 1 of dry-treating a surface A of a plastic to obtain a dry-treated plastic having a surface B that has been dry-treated; a step 2 of wiping the surface B with a cleaning tool containing a composition for wiping, the composition containing at least one solvent selected from the group consisting of water and polar solvents, and a silane coupling agent, to obtain a cleaned plastic having a surface C that has been wiped with the cleaning tool; and a step 3 of applying at least one selected from the group consisting of adhesives and primers on the surface C to obtain a laminated body.
