Zusammenfassung:Disclosed is an ultraviolet-curable pressure sensitive adhesive composition comprising an ultraviolet-curable pressure sensitive adhesive component and a phosphorus type photopolymerization initiator. Also disclosed is an ultraviolet-curable pressure sensitive adhesive sheet obtained by coating a substrate with the ultraviolet-curable pressure sensitive adhesive composition. The ultraviolet-curable pressure sensitive adhesive composition is capable of retaining ultraviolet curing properties even if the ultraviolet-curable pressure sensitive adhesive sheet is brought into contact with wash water for a long period of time.
