example 1

[0070] The present invention will be explained below with reference to FIGS. 1 and 2 .

[0071] The first electrode layer 2 (100 nm in thickness) was formed by ITO sputtering on a polyethylene terephthalate sheet (DIAFOIL T-100, Mitsubishi Polyester Film Corporation) having a thickness of 100 μm used as the transparent substrate 1 . The second electrode layer 5 (thickness 100 nm) was obtained by performing ITO on another polyethylene terephthalate sheet (DIAFOIL T-100, Mitsubishi Polyester Film Corporation) having a thickness of 100 μm used as the second transparent substrate 3. sputter formation. Subsequently, a ZnS:Cu solution (FEL-190, Fujikura Kasei Co., Ltd.) was coated on the ITO face of the first electrode layer 2, thereby forming a light emitting layer 4 with a thickness of 40 μm. The ITO faces of the second electrode layer 5 are stacked on the light emitting layer 4 in such a manner that they are bonded to each other. Drying was performed at 100° C. for 30 minutes u...

[0073] The present invention will be explained below with reference to FIGS. 3 and 4 .

[0074] The first electrode layer 2 (100 nm in thickness) was formed by ITO sputtering on a polyethylene terephthalate sheet (DIAFOIL T-100, Mitsubishi Polyester Film Corporation) having a thickness of 100 μm used as the transparent substrate 1 . Subsequently, a ZnS:Cu solution (FEL-190, Fujikura Kasei Co., Ltd.) was coated on the ITO face of the first electrode layer 2, thereby forming a light emitting layer 4 with a thickness of 40 μm. After drying at 100° C. for 30 minutes using a drier, a barium titanate solution (FEL-615, Fujikura Kasei Co., Ltd.) was further applied thereon to form dielectric layer 9 with a thickness of 30 μm. Drying was performed at 100° C. for 30 minutes using a drier as described above, thereby obtaining a sheet 10 . Thereafter, a conductive paste 11 (FEL-685, Fujikura Kasei Co., Ltd.) having the functions of a second electrode layer and a see-through control laye...

[0076] The present invention will be explained below with reference to FIG. 5 .

[0077] Using a color printer (DocuCentre Color f360, Fuji Xerox Co., Ltd.), on a polyethylene terephthalate sheet (DIAFOIL T-100, Mitsubishi Polyester Film Corporation) used as a transparent substrate with a thickness of 100 μm Text is printed on one surface, then black is printed across the entire surface on the other side to create a see-through control layer. Thus, a printed polyethylene terephthalate sheet 31 (100 µm in thickness) was obtained. A printed polyethylene terephthalate sheet 31 was subjected to perforation using a flat die cutter (RFP-S20, UHT CORPORATION) in such a manner that holes of 1 mm were formed therethrough in a matrix pattern at an interval between hole centers of 2 mm deal with. Thus, a sheet-shaped decorative material 32 having see-through properties is manufactured. Subsequently, the EL tube 33 (Lumiline TM EBAC Corporation) are disposed around the edge of the sh...

Abstract

Luminescent sheet having see-through property, luminescent decorative material, and method of producing the same are provided. This invention relates to a luminescent sheet having see-through property, through which see-through holes are formed and which comprises a means of causing luminescence; a method of producing the luminescent sheet, comprising carrying out perforation processing on a sheet body comprising a means of causing luminescence so as to impart see-through property to such sheet body; and a method of producing the luminescent sheet, comprising carrying out perforation processing on a sheet body so as to impart see-through property to such sheet body and then applying a means of causing luminescence to the sheet body. According to this invention, a luminescent decorative material having see-through property, which is visible even at night and of which different decorative properties are visible in the daytime or under lighting due to the presence or absence of luminescence, is provided.

Description

technical field [0001] The present invention relates to a luminescent sheet and a luminescent decorative material which can be applied to windows of commercial buildings, vehicles, etc. as an advertising medium, a decorative medium or a security sheet, and also relates to a manufacturing method thereof. Background technique [0002] In order to manufacture special-purpose decorative materials (sheets) with see-through properties, on which different images can be displayed on either side of the sheet, respectively, the following methods are suggested and actually used: To obtain special A method of decorating materials of use, comprising each image consisting of different pixels depicted by dots on each sheet, layered on top of each other in a precise manner, and then one of the sheets is removed from the other such that the removed sheet's Pixels are transferred to pixels of another sheet (Japanese Patent Laid-Open (Kokai) No. 5-92694A (1993)); and inks having different adhe...
