Zusammenfassung:	PURPOSE:The titled pressure-sensitive adhesive sheet having characteristics such as water resistance, weather resistance, opacifying properties, printability, etc., by using a specific base paper as a surface substrate, and setting a repeatedly releasable pressure-sensitive adhesive layer on the back of the base paper. CONSTITUTION:(A) The surface of paper base having improved water resistance, interlaminar strength, and flexibility is coated with an aqueous pigment coating compound comprising (B) carboxy modified latex and (C) a water-resistant agent (e.g., urea formalin resin), and (D) a blending ratio of an adhesive to form an undercoated layer, then, the surface is coated with (E) an aqueous pigment coating compound comprising a pigment and an adhesive as main components to form a topcoated layer, so that the surface substrate is prepared. The back of the substrate is provided with a repeatedly releasable pressure- sensitive adhesive layer, to give the aimed sheet. The component D has 30-80 pts.wt. adhesive based on 200pts.wt. pigment, the component B in the adhesive with high blending ratio is 10-70pts.wt., and the amount of the component C blended is preferably 2-25pts.wt. based on 100pts.wt. pigment.
