Abstract
The present invention relates to it is a kind of can infraluminescence optical color variable pigment, the camouflage paint by optically variable films crush form, optically variable films include intermediate base layer, Al layers, MgF2Layer and Cr layers, Al layers, MgF2The both sides that layer and Cr layers are symmetrically deposited on intermediate base layer successively from inside to outside, intermediate base layer is by IR fluorescence powder NaYF4:Yb is made.Compared with prior art, the pigment that prepared by the present invention has the effect that color change is produced with view transformation, is irradiated by 980nm infrared lasers, and pigment of the invention can produce obvious green emitting point, with double anti-forge function.
Description
Technical field
The present invention relates to a kind of optical color variable pigment, more particularly, to it is a kind of can infraluminescence optical color variable pigment.
Background technology
Optical color variable pigment is a kind of anti-fake material being made according to multilayer films interference optical principle, and its distinctive color becomes
Changing effect can have discolouration with the change of viewing angle, and fantasy coloured effect, other method can be produced to replicate.Early in
1988, Reserve Bank of Canada just employed this optically variable films on Canadian dollar, after the U.S. crushed optical thin film in 1996, system
Into color shifting ink, false proof for 100 dollars, also some national companies mix coating, paint after optical thin film is crushed
In, the ornament of colors changing hue is manufactured, thus, multilayer optical film powder is a kind of widely used camouflage paint.
The content of the invention
The purpose of the present invention be exactly provided for the defect for overcoming above-mentioned prior art to exist it is a kind of make it is simple, have
Antiforge function, have a wide range of application can infraluminescence optical color variable pigment.
The purpose of the present invention can be achieved through the following technical solutions：
It is a kind of can infraluminescence optical color variable pigment, the camouflage paint by optically variable films crush form, described discoloration
Film includes intermediate base layer, Al layers, MgF2Layer and Cr layers, described Al layers, MgF2Layer and Cr layer from inside to outside successively symmetrically deposit
In the both sides of intermediate base layer, described intermediate base layer is by IR fluorescence powder NaYF4:Yb is made.
The particle diameter of described camouflage paint is between 1 micron~200 microns.
Described optically variable films is prepared using physical vapor deposition or chemical vapour deposition.
The thickness of described optically variable films is 1 micron~1000 microns.
Described IR fluorescence powder NaYF4:Yb produces obvious green emitting point under the irradiation of 980nm infrared lasers.
Compared with prior art, the present invention has advantages below and beneficial effect：
(1) pigment prepared by the present invention has the effect that color change is produced with view transformation.
(2) pigment of the invention is irradiated by 980nm infrared lasers, obvious green emitting point can be produced, with dual
Antiforge function.
(3) pigment manufacture method of the invention is simple, has a wide range of application.
