PROBLEM TO BE SOLVED: To provide an adhesive sheet free from the problem of a blocking and developing sufficient adhesive force by the application of a prescribed pressure even if, to the adhesive layer surface, silicon, etc., adheres, in the printing or copying operation. SOLUTION: The adhesive sheet has an adhesive layer at a prescribed part of a sheet substrate. The adhesive layer has no adhesivity in dried state and develops adhesivity by coming into contact with a plasticizer. An adhesivity imparting layer composed of a binder compounded with microcapsules containing a plasticizer is formed at the other part of the sheet substrate adjacent to the adhesive layer and the adhesive force is developed by the application of a prescribed pressure on the sheet. A binder which does not develop adhesive force even by coming into contact with the plasticizer is used as the binder. COPYRIGHT: (C)2004,JPO
