Description
Technical field
The present invention relates to fields of pigments, can induce secondary filter pigment more particularly, to one kind；It more particularly relates to be used for
The inducible polychrome filter pigment for forming induction pattern of other products such as ink, coating.
Technical background
Can induce polychrome filter pigment has been a kind of well known product, is chiefly used in currency security and brand protection field.
" magnetic thin film interference's device or pigment and its manufacturing method contain this magnetic to the patent CN1459034A of Sicpa Holding S.A
Property film interference device printing ink or coating composition, secret papers and application ", content teaches such product emphatically
Design technology, technology of preparing and application technology.Due to the defect of Color Scheme technology, secondary optical filtering is not done to interference colours,
So there is no monochromatic better pigment, local tyrant's gold system that the honorable camouflage paint of new edition RMB is provided by Xi Bai company
It is very not identical with the background color red of 100 yuans of bills.
Summary of the invention
Present invention mainly solves the problem of be the secondary optical filtering of building, it is monochromatic more preferable to obtain the not obtainable front of original structure
Inducible filter pigment.
The present invention provides a kind of inducible filter pigment, is following symmetrical laminated construction: medium filter layer/half reflection
Layer/dielectric layer/reflecting layer/induction reflecting layer/reflecting layer/dielectric layer/semi-reflective layer/medium filter layer.
The dielectric layer can choose magnesium fluoride (MgF2), silica (SiO2), ice crystal (Na2AlF6) etc. materials.Europe
Can have to free state fluorine ion in the multinomial safe and healthy regulation of alliance and forbid requiring, fluorine can also be abandoned by such as encountering this kind of situation
Change magnesium material, other materials will not human body and environment generation negative impact.Optics can be used in the thickness of the dielectric layer
Thickness QWOT, the reference wavelength λ of corresponding selection0Value is 300~800nm；Physical thickness selection is 100~5000 nanometers.
The induction reflector material selects to be to compare the key link: should meet the need as reflection layer function
It asks, also to meet the needs of inducing function, at the same time, it is also necessary to meet it and be wanted to what human body and environment did not had a negative impact
It asks.The metal material of group of the lanthanides: the materials such as gadolinium, dysprosium, holmium, erbium, bismuth has been selected in specific implementation of the invention.Also it can choose selection
Iron, cobalt, nickel, iron-cobalt-nickel mixture or the alloy material containing iron-cobalt-nickel.The thickness of the induction reflector material is equally wanted
Consider to meet the function of induction and the function of reflected light, thus material thickness according to it is corresponding it is magnetic different it is corresponding not
Together, but there is a lower limit requirement, be not easy to induce if too thin, the lower thickness limit of lanthanide series metal is 20 nanometers, iron-cobalt-nickel, iron-cobalt-nickel mixing
The lower thickness limit of object or the alloy containing iron-cobalt-nickel is 10 nanometers, if induction reflecting layer thickness low LCL can be to external world's guidance not
Sensitivity or even Induction failure.
Reflector material selection aluminum material perhaps aluminum alloy materials aluminum material or aluminum alloy materials as reflecting layer
The effect of realization is that the final reflectivity of filter is relatively high, and color monochrome saturation degree is relatively high.
The semi-reflective layer material can choose the metal material of group of the lanthanides: the materials such as gadolinium, dysprosium, holmium, erbium, bismuth, in addition this
Layer does not need the demand that selection has induction, so it is also an option that titanium material or chromium material.
The present invention provides another inducible polychrome filter pigment can be Jie in order to improve the monochromaticjty of material colour developing
Matter layer is set as optical filtering membrane system stack layers；Then the inducible polychrome filter pigment is following symmetrical laminated construction:
Dielectric coating series stack layers/semi-reflective layer/dielectric layer/reflecting layer/induction reflecting layer/reflecting layer/dielectric layer/half reflection
Layer/dielectric coating series stack layers.
The dielectric coating series heap is (aH1bL1)nH1, wherein n is integer；A, b is multiplier；High refraction in H1 layers of use
The material of rate, minimum refractive index N coefficient are not less than 2.0, express H1 thickness using optical thickness, selectable range defines
The numerical value of a quarter between 50-1000 nanometers；L1 layers use low-index material, and largest refractive index N is not more than
1.6, thickness is expressed using optical thickness, selectable range is defined in the numerical value of a quarter between 50-1000 nanometers.When
So more complicated structure is more accurate to the control of optical filtering, while the difficulty prepared also will increase.
Compared to the prior art, the invention has the following advantages that
The present invention uses metallic aluminium or aluminum alloy materials as reflecting layer on the both sides in induction reflecting layer, reflects in this case
The effect that layer is shown can be much higher than the effect of siderochrome nickel or rare earth material as reflecting layer；Additionally, due to there is induction reflecting layer
Presence, metallic aluminum material or aluminium alloy can choose thinner thickness on thickness.
In addition, secondary filtering structure is constructed on the basis of original single filtering structure, so that it is better to obtain monochromaticjty
Product；Capability improving of the introducing of medium membrane stack to optical filtering, single filter to form dominant hue, and dominant hue is repaired in secondary optical filtering
Just, unwanted stray light is filtered again；The good filter of more monochromaticjty can be obtained through this structure.
