To provide a pressure-sensitive adhesive sheet highly suitable for a high-speed inkjet printer, having high ink-drying property and satisfying the adhesivity as a paper for confidential post card, etc., and offset printability.
The pressure-sensitive adhesive sheet has an adhesive layer on at least one surface of a substrate sheet. The adhesive layers are bondable by placing the layers opposite to each other and applying a high pressure and the bonded adhesive layers are peelable. The adhesive layer contains an adhesive, a fine particle filler, an inkjet ink fixing agent and a binder resin. The binder resin is composed of at least one compound selected from a partially saponified polyvinyl alcohol having a saponification degree of ≤90 mol% and a polymerization degree of ≤1,000 and an organic polymer compound having a glass transition point of -30 to +50°C and a gel fraction of 30-90 mass% in toluene.
