Description
Technical field
The present invention relates to be applicable to a kind of optical anti-counterfeiting element of all kinds of high safety products such as banknote, credit card, passport, marketable securities and high value added product; And relate to the product that has this Security element; Specifically; Relate to a kind of Security element that has interference light change characteristic and diffraction light change characteristic simultaneously, and further relate to the product that has this Security element, for example use banknote or the cheque paper of this Security element as opened window safety line.
Background technology
The application of optical anti-counterfeiting technology in high demand for security products such as banknote, credit card, passport and marketable securities and high value added product is very extensive, and has obtained extraordinary effect.
The optical anti-counterfeiting technology adopts diffraction light change image usually and interferes light variation image to realize false proof purpose.
Diffraction light change image, such as hologram, dynamic diffraction etc., its optical texture is the diffraction grating of relief type, utilizes its diffraction reproduced image.This image can have stereoeffect, dynamic change, change color etc. with as popular anti-counterfeiting characteristic, can have implicit pattern, coding pattern etc. again and be used as professional and expert's anti-counterfeiting characteristic.This type anti-fake product is made through adopting mould pressing process that diffraction structure is transferred on the basement membrane usually.
Mould pressing process has two kinds, and the one, be coated with mold pressing on the basement membrane of metallic reflector (being called hard pressure); The one, do not having mold pressing on the basement membrane of metallic reflector (being called soft pressure), and then whether determining the plating reflecting layer according to product requirement.Metallic reflector can improve the brightness of diffraction light change image greatly.
The metal of metallic reflector is aluminium normally, also can be other metal, such as silver, nickel, copper etc.Metallic reflector can be continuous, and cover whole diffraction light change image fully; Also can be discontinuous and cover part diffraction light change image, wherein cover part and unmasked portion form patterns such as character, sign, sign.
GB2,136,352 disclose a kind of Security element that has the diffraction light change image of above-mentioned metal pattern.Basement membrane can be single plastic sheeting, also can be to have to be used to improve the mold pressing imaging layer of diffraction light change image quality and the plastic sheeting of other functional layers.According to requirement of products and environment for use, can be chosen on the metallic reflector that processes the coating protective layer or be covered with diaphragm, to improve the stability of product.
Interfering light variation image, is the image that the change color of utilizing the interference effect of optical film structure to produce forms.It is compared with diffraction light change image, and the change color contrast is strong, differentiates easily.Interference light becomes image technique and utilizes pearl printing ink, photochromatic printing ink, single or multiple lift blooming, composite plastic film to wait and realize usually.The different single layer optical film of optical thickness has the various colors variation effect, adds in the printing ink and just constitutes pearl printing ink and be broken into fractionlet to this blooming.Multi-layer optical film comprises deielectric-coating and medium/metal film.
Deielectric-coating can be the assembly of thin films structure that high refractive index medium and low refractive index dielectric replace, and for example Chinese patent discloses a kind of multilayer dielectric film No. 00814584.9.Typical medium/metal film comprises three-decker, is followed successively by absorbed layer, dielectric layer and reflecting layer from top to bottom.Absorbed layer is metal (perhaps metallic compound) layers of several nanometers to tens nanometer thickness; Dielectric layer is the transparent dielectric layer with certain optical thickness, and itself can be the sandwich construction of different medium; The reflecting layer also is a metal level, and it can adopt identical with absorbed layer or different metallic (the most frequently used is aluminium).Wherein, absorbed layer is very thin, guarantees that light can see through.And different with absorbed layer be that thicker tens nanometers that are generally in reflecting layer can not let light see through to several microns.The reflecting layer can be discontinuous, and metal section and part forms patterns such as character, sign, sign with no metal section and part.Chinese patent discloses the multiple layer metal/deielectric-coating of different structure for No. 99809993.7 and No. 00818424.0.Be broken into fractionlet to multilayer film as just constituting photochromatic printing ink in the pigment adding printing ink, one Chinese patent application discloses a kind of method of making photochromatic printing ink pigment No. 97194750.3.
Chinese patent No. 00810089.6 and No. 00818424.0, and one Chinese patent application has the optical anti-counterfeiting element that interference light becomes characteristic and diffraction light change characteristic when disclosing multiple different structure for No. 03802372.5.Their common feature is to have substituted the metallic reflector in the common diffraction light change image element with optical interference coating, perhaps interferes light variation image and diffraction light change image to be positioned at the both sides of a hyaline layer or film.These structures make diffraction light change characteristic and the interference light change characteristic in the same area occur simultaneously, can produce some unique optical effects.But, in all said structures, there is not the independent reflecting layer that belongs to diffraction light change image, if optical interference coating is the medium/metal film, the shared metallic reflector of diffraction structure and inteferometer coating then.
