Abstract

The invention provides a partial metallic hologram wherein a light reflecting layer is formed easily at a low price and the light reflecting layer and the hologram region are formed in a pattern having an arbitrary shape, and a method of producing the same. A metallic hologram comprises a light reflecting layer, wherein the light reflecting layer is formed by coating or printing with a high brightness coating agent.

Claims

1. A metallic hologram comprising a light reflecting layer, wherein the light reflecting layer is formed by coating or printing with a high brightness coating agent.

2. The metallic hologram according to claim 1, wherein the high brightness coating agent contains a binder resin and metal thin film flinders.

3. The metallic hologram according to claim 2, wherein the metal thin film flinders are surface-treated with an organic fatty acid, methylsilyl isocyanate or a cellulose derivative.

4. The metallic hologram according to claim 1, wherein the light reflecting layer is formed in a pattern having an arbitrary shape.

5. The metallic hologram according to claim 1, wherein the hologram region is formed in a pattern having an arbitrary shape.

6. A method of producing a metallic hologram comprising a light reflecting layer, which comprises forming the light reflecting layer by coating with a high brightness coating agent.

7. The method of producing a metallic hologram according to claim 6, wherein the light reflecting layer is formed in a pattern having an arbitrary shape by printing with a high brightness coating agent.

8. The method of producing a metallic hologram according to claim 6, wherein the hologram region is formed in a pattern having an arbitrary shape by printing a transparent varnish.

9. The method of producing a metallic hologram according to claim 7, wherein the hologram region is formed in a pattern having an arbitrary shape by printing a transparent varnish.
