Title:
イメージ表示シートおよびイメージ表示システム
Document Type and Number:
Japanese Patent JP4225599
Kind Code:
B2
Abstract:
An imaging element is disposed on a front surface of a retroreflective sheeting to form an image-displaying sheeting. The imaging element includes a light-transmitting prismatic sheeting that has a surface provided with a plurality of parallel prisms. The imaging element also includes an adhesive layer that adheres the prismatic sheeting to the front surface of the retroreflective sheeting. At least a portion of the imaging element is shaped in the form of indicia. In some cases the prismatic sheeting itself is shaped in the form of indicia. In other cases the imaging element includes a light-transmitting colored layer disposed on the front surface of the retroreflective sheeting and shaped in the form of indicia. In the latter case, the prismatic sheeting can be shaped as before to match the indicia-shaped colored layer, or it can extend continuously across the entire retroreflective sheeting. A stationary light source can be added and suitably positioned to enhance visibility of the image in a viewing plane.
