PROBLEM TO BE SOLVED: To prevent the shape of a light source and the luminescence pattern of a light guide board from appearing irregularly without deteriorating the quality characteristic of a printed image and to provide a uniform decorative illumination display by forming a sheet separately provided with a light diffusing layer and an ink jet recording layer. SOLUTION: A sheet 1 for manufacturing a transmissive display board is provided with a light diffusing layer 13 and an ink jet recording layer 11, or the light diffusing layer 13 may be provided on one face of a base material 12, and the ink jet recording layer 13 may be provided on the other face of the base material 12. Polyester, polycarbonate, cellulose acetate, polyimide, polyethylene, polypropylene or polyvinyl chloride can be used for the base material 12. The light diffusing layer 13 is a layer for obtaining a uniform light source by making the luminescence pattern of a light guide board inconspicuous, and it contains at least a synthetic resin binder and a light diffusing agent. The ink jet recording layer 11 is normally a single layer or multiple layers, and it is mainly made of a hydrophilic polymer or a water-soluble polymer. |
