PROBLEM TO BE SOLVED: To provide an ultraviolet-curable pressure-sensitive adhesive which, when two curable layers formed from this adhesive are faced, tightly contacted under a high pressure, and thus bonded to each other, exhibits a high adhesive power and which is cured quickly; and a pressure-sensitive adhesive printing sheet which, when the two curable layers are faced, tightly contacted under a high pressure, and thus bonded to each other, exhibits a strong adhesive power and which, when peeled as required, can be peeled off easily. SOLUTION: This pressure-sensitive adhesive is prepared by incorporating a urethane acrylate oligomer and a photopolymerizable acrylic monomer having a Tg of 0 deg.C or lower, each in a specified proportion, into the adhesive and by using a photopolymerization initiator and a photopolymerization accelerator having an amino group or by using a photopolymerization having an amino group.
