PURPOSE:To obtain a contact adhesive which is excellent in wear resistance, can bond even when an oil layer is present in an adhesive layer and does not set off the surface of other materials, by mixing a synthetic rubber latex adhesive with a particular aggregate of particulate silica. CONSTITUTION:A synthetic rubber latex adhesive y is mixed with an aggregate of a particulate silica z coated with an org. matter and treated for inactivation to obtain a contact adhesive x. The contact adhesive x is applied to the bonding surfaces f, f and dried. The bonding surfaces f, f are superposed and pressed. In this case, bonding can be conducted even when an oil layer o is present in a contact adhesive layer x. Therefore, this contact adhesive x is suitable for bonding a bonding printing paper. |
