Abstract
The application discloses an anti-counterfeiting pigment composition and a preparation method thereof. The anti-counterfeiting pigment composition comprises: the pigment with the anti-counterfeiting characteristic and the infrared reflection pigment have the following mass ratio of 10-80 percent: 20% -90%, wherein the transmittance of the infrared reflection pigment to visible light wave band is more than 90%, and the reflectance of the infrared reflection pigment to infrared wave band with interval of 780nm-1200nm is more than 85%. The anti-counterfeiting pigment composition provided by the application is a combination of a pigment with anti-counterfeiting characteristics and an infrared reflection pigment, has multiple anti-counterfeiting effects, and is good in color development and high in color uniformity.
Description
Technical Field
The application relates to the technical field of optical anti-counterfeiting, in particular to an anti-counterfeiting pigment composition and a preparation method thereof.
Background
In recent years, with the development of anti-counterfeiting technology, a plurality of color-changing and special synthetic materials gradually expose the corners. The color-changing material is widely applied to the traditional visual anti-counterfeiting technology, and more invisible anti-counterfeiting technologies are added to the color-changing material, such as infrared anti-counterfeiting and magnetic anti-counterfeiting.
However, infrared highly reflective materials are often monochrome pigments, and can only be used to authenticate security elements on specific identification devices. The magnetic and infrared double anti-counterfeiting can be printed only by two different kinds of printing ink at present and cannot be directly combined for use.
Disclosure of Invention
The application provides an anti-counterfeiting pigment composition and a preparation method thereof, the anti-counterfeiting pigment composition is easy to prepare, low in cost and capable of achieving multiple anti-counterfeiting effects, and the anti-counterfeiting pigment composition is good in color development and high in color uniformity.
In order to solve the technical problem, the application adopts a technical scheme that: there is provided a security pigment composition comprising: the pigment with the anti-counterfeiting characteristic and the infrared reflection pigment have the following mass ratio: 10-80%, and the mass ratio of the infrared reflection pigment is as follows: 20% -90%, wherein the transmittance of the infrared reflection pigment to visible light wave band is more than 90%, and the reflectance of the infrared reflection pigment to infrared wave band with interval of 780nm-1200nm is more than 85%.
Furthermore, the anti-counterfeiting pigment composition has a preset reflectivity for an infrared band and a preset transmittance for a visible light band, the pigment with anti-counterfeiting characteristics has a preset anti-counterfeiting index, the preset anti-counterfeiting index combines the preset reflectivity and the preset transmittance to obtain an identification index, and the identification index is used for anti-counterfeiting identification.
Further, the pigment with the anti-counterfeiting characteristic comprises optically variable pigment and/or magnetic pigment, and the preset anti-counterfeiting index comprises magnetic index and/or optically variable index.

Then comparing the measured actual result with the test data of the composition in the database under the same proportion, and if the measured result is consistent with the data in the corresponding database or the difference between the measured result and the data in the database is small, such as the error does not exceed five percent, the formulated anti-counterfeiting pigment composition is qualified; if the measured result is not consistent with the corresponding test data in the database, or the difference between the two is large, for example, the error exceeds five percent, the formulated composition is considered to be unqualified, and the formulated composition needs to be adjusted. After the adjustment, the anti-counterfeiting index and the infrared data of the blended composition are measured continuously, and the obtained measurement result is compared with the test data until the measurement result is consistent with the test data.
