発明の名称 (英語) Security mark, method, device and producing method thereof, and ink for security mark and producing method thereof NEW
発明の概要(英語) (TW201601943)
As a technique capable of achieving higher security performance in methods for authenticating security marks that use a photochromic compound, provided is an authentication method that comprises: a process for irradiating excitation light on a security mark containing a photochromic compound; a process for acquiring first security information relating to temporal changes of the absorption spectrum and/or the reflection spectrum of the security mark after irradiation of the excitation light; and a process for comparing the acquired first security information with previously acquired first security information on said security mark.
In said authentication method, the security mark preferably contains two or more photochromic compounds for which the coloring and/or the rate of decoloring after coloring as a result of a photochromic reaction differ.
特許請求の範囲(英語) [claim1]
1. A authentication methods, it is the authentication method of safe mark, includes: Will stimulate the light illumination in containing light to safe mark procedure (process) that the color deterioration chemical compound makes;
With obtaining about the safe mark after illumination stimulation light by the absorption spectrum that forms and/or reflection spectrum change the procedure of first security information on time.
[claim2]
2. Like the request 1 authentication method, it further contains the first security information that the checkup obtains, with on the first security information procedure that this safe mark obtains in advance.
[claim3]
3. Like request 2 authentication method, when defers to the first security information that the acquisition temperature correction obtains, carries on with on the checkup that of first security information this safe mark obtains in advance.
[claim4]
4. Like request item 1 to threes any authentication method, this safe mark is contains based on the light after the coloration of metachromasia and/or the coloration the achromatic speed different over 2 light makes to the color deterioration chemical compound.
[claim5]
5. Like request item 1 to fours any authentication method, this safe mark department further contains the phosphor to make, and further includes: Obtains about from the fluorescence spectrum second security information procedure that this safe mark emits;
With the second security information that the checkup obtains, with on the second security information procedure that this safe mark obtains in advance.
[claim6]
6. Like request item 1 to five any authentication method, and/or the reflection spectrum determination obtains this first security information using the time analysis absorption spectrum.
[claim7]
7. 1 kinds of authentication installments of safe marks, it is includes: The stimulation uses the photo source, it is containing the ultraviolet ray and/or wave length 400-600nm the stimulation light illumination of light in the safe mark;
The determination uses the photo source, it is the visible light and/or near infrared light illumination in this safe mark;
The light detector, it is the examination by the visible light that this safe mark is formed and/either the near-infrared light transmitted light or the reflected light;
With the analysis department, it is storage from the signal that this light detector outputs, as about the safe mark after illumination stimulation light by the absorption spectrum that forms and/or reflection spectrum change the first security information on time.
[claim8]
8. Like the request 7 authentication installments, it has further the demonstration department, this analysis department preservation on the first security information that this safe mark obtains in advance, checks the first security information that obtains with the first security information that preserves, but result output in this demonstration department.
[claim9]
9. Like request 8 authentication installments, this analysis department preservation stipulated when this light to the achromatic speed and temperature of color deterioration chemical compound the adjustment information of relations, based on this adjustment information, acquisition the temperature correction according to the first security information that obtains, carries on with the checkup that of first security information preserves.
[claim10]
10. 1 kinds of safe marks use the printing ink, it is contains based on the light after the coloration of metachromasia and/or the coloration the achromatic speed different over 2 light makes to the color deterioration chemical compound.
[claim11]
11. 1 kinds of safe marks with the printing ink manufacture method, it are contains the mix based on the light after the coloration of metachromasia different and/or the coloration the achromatic speed different over 2 light to the color deterioration chemical compound, after making the illumination stimulation light the absorption spectrum and/or the reflection spectrum change design step on time.
[claim12]
12. 1 kinds of safe marks, it is contains based on the light after the coloration of metachromasia and/or the coloration the achromatic speed different over 2 light makes to the color deterioration chemical compound.
[claim13]
13. 1 manufacture methods of safe marks, it is contains the mix based on the light after the coloration of metachromasia different and/or the coloration the achromatic speed different over 2 light to the color deterioration chemical compound, after making the illumination stimulation light the absorption spectrum and/or the reflection spectrum change design step on time.
[claim14]
14. 1 kinds of goods of additional safe marks, this safe mark is contains based on the light after the coloration of metachromasia and/or the coloration the achromatic speed different over 2 light makes to the color deterioration chemical compound.
