The display sheet comprises: a sheet-like member, which comprises a support, such as a sheet of paper and a plastic film, and a 30 to 500 micron thick flexible microporous suction sheet which is disposed on a back surface side of the support and in which an infinite number of fine and flexible depression pores 5 to 300 microns in diameter are formed; and a release film, which releasably covers a surface of the microporous suction sheet to protect the microporous suction sheet, is 10 to 100 micron thick and has a smooth surface. Adhering workability, release workability, storability and reusability are improved by providing the microporous suction sheet. Display contents are printed on a printing receptive layer formed on a front surface side of the support, on the microporous suction sheet or on a printing receptive layer formed on the microporous suction sheet. This display sheet is suitable for front surface application when display contents are printed on the printing receptive layer and for the back surface application when display contents are printed on the microporous suction sheet or on a printing receptive layer formed on the microporous suction sheet.
A display sheet comprising:
A display sheet in which display contents are printed out with a water base ink or an oil base ink on a surface of a 30 to 500 micron thick flexible microporous suction sheet in which an infinite number of fine and flexible depression pores 5 to 300 microns in diameter are formed, a transparent smooth release film being stuck to the printed surface.
A method of performing front surface application of a display sheet including a sheet-like member comprising a support and a 30 to 500 micron thick fine and flexible microporous suction sheet which is disposed on a back surface side of the support and in which an infinite number of fine and flexible depression pores 5 to 300 microns in diameter are formed, and a release film with a smooth surface, a thickness of 10 to 100 microns and a yield point elongation of not less than 2% which releasably covers a surface of the microporous suction sheet to protect the microporous suction sheet, said method comprising the steps of:
A method of performing back surface application of a display sheet including a sheet-like member comprising a 30 to 500 micron thick flexible microporous suction sheet in which an infinite number of fine and flexible depression pores 5 to 300 microns in diameter are formed,
A method of performing back surface application of a display sheet including a sheet-like member comprising a 30 to 500 micron thick flexible microporous suction sheet in which an infinite number of fine and flexible depression pores 5 to 300 microns in diameter are formed,
