Abstract

An image display is to be transferred from a support onto a substrate and displays an image including personal information. The image display includes a base layer releasably supported by the support and having a light-transmitting property, and an image display layer including a hologram and/or diffraction grating and transferred onto the base layer by a thermal transfer method using a thermal head. The image display layer displays an image including at least a piece of the personal information. An individual authentication medium including the image display, and manufacturing methods of the image display and individual authentication medium are also described.

Claims

1. An image display that is to be transferred from a support onto a substrate and displays an image including personal information, comprising:

a base layer releasably supported by the support and having a light-transmitting property; and

a first image display layer including a hologram and/or diffraction grating and transferred onto the base layer by a thermal transfer method using a thermal head, the first image display layer displaying a first image including at least a piece of the personal information.

2. The image display according to claim 1, wherein the first image display layer further includes an ink layer.

3. The image display according to claim 2, wherein an image displayed by the hologram and/or diffraction grating is bordered with a image displayed by the ink layer.

4. The image display according to claim 2, wherein the ink layer is made of a color ink.

5. The image display according to claim 4, wherein a color of the color ink and a color of the substrate are complementary colors.

6. The image display according to claim 1, further comprising a second image display layer facing the base layer and displaying a second image by utilizing light absorption.

7. The image display according to claim 6, wherein the first image includes a piece of the personal information, while the second image includes another piece of the personal information.

8. The image display according to claim 7, wherein the first image includes first personal information, the second image includes second personal information, and the first and second personal information are information of the same person.

9. The image display according to claim 8, wherein at least one of the first and second images includes biometric information.

10. The image display according to claim 8, wherein the first and second images include the same facial image.

11. The image display according to claim 1, wherein the first image display layer includes dot- shaped portions, and each center of the dot-shaped portions is located on a lattice point of a virtual planar lattice.

12. The image display according to claim 1, further comprising an adhesive layer facing the base layer with the first image display layer interposed therebetween.

13. An individual authentication medium comprising:

the image display according to claim 1; and

the substrate having the image display transferred from the support.

14. A method of manufacturing an image display that is to be transferred from a support onto a substrate and displays an image including personal information, comprising:

transferring a part of a transfer material layer including a hologram and/or diffraction grating onto the base layer releasably supported by the support by a thermal transfer method using a thermal head so as to form an image display layer on the base layer, the image display layer including a part of the hologram and/or diffraction grating and displaying an image including at least a piece of the personal information.

15. The method according to claim 14, wherein the transfer material layer further includes an ink layer, and the image display layer further includes a part of the ink layer.

16. A method of manufacturing an individual authentication medium, comprising:

forming an image display comprising a base layer and an image display layer and displaying an image including personal information, wherein the formation of the image display includes transferring a part of a transfer material layer including a hologram and/or diffraction grating onto the base layer releasably supported by a support by a thermal transfer method using a thermal head so as to form the image display layer on the base layer, the image display layer including a part of the hologram and/or diffraction grating and displaying the image including at least a piece of the personal information; and

transferring the image display from the support onto a substrate of the individual authentication medium.

17. The method according to claim 16, wherein the transfer material layer further includes an ink layer, and the image display layer further includes a part of the ink layer.
