<p>An adhesive composition exhibiting an adequately controlled adhesive bonding strength when paper sheets coated therewith are bonded together and adapted for subsequent separation of the bonded sheets of paper by peeling comprises as essential ingredients: (a) a rubber latex; (b) a silica gel powder having a specified average particle diameter; and (c) a starch, preferably having a specified particle diameter, e.g. wheat starch, each in a specified weight proportion. In addition to good balance between reliability of the adhesive bonding and subsequent peelability, a paper sheet coated with the adhesive composition is protected from decrease in adhesiveness even when the surface is contaminated with a silicone oil and from problems due to blocking when adhesive-coated sheets are stacked one on the other with the adhesive-coated surfaces in direct contact with each other.</p> |
