Description
Technical field
The invention belongs to false-proof film material technology field, be specifically related to a kind of laminated film with reflection holography and angular color change dual nature.
Background of invention
In the prior art, reflection hologram (seeing Chinese patent 021374732) with the making of superpolymer photosensitive material, have very high reflection efficiency, good field angle and stereoeffect, can be used as anti-fake material and ornament materials, be different from embossed holographic and seek for the uniqueness of material and the uniqueness of vision, improved false proof grade to a certain extent.Specific pattern or the literal made of angular photochromic material have angular color change performance (seeing Chinese patent 021369747), and the material variable color is obvious, and difficulty is forged in identification easily, thereby reach effectively false proof effect.But, above-mentioned two kinds of technology are combined, prepare the false-proof film that has reflection hologram and angular color change pattern function concurrently, to improve anti-counterfeiting power, be not reported so far.
Summary of the invention
The objective of the invention is to propose a kind of false-proof film that has reflection hologram and angular color change information pattern dual nature concurrently and preparation method thereof.
The false-proof film that the present invention proposes is made of through articulamentum is compound two functional layers, wherein, one is to have high brightness, transparent reflection holography layer with great visual angle, another is that angular color change pattern or literal are arranged on the surface, and the color after changing viewing angle presents the angular color change patterned layer of different color.
Among the present invention, the reflection holography functional layer 3 that described reflection holography layer 10 is made up of coverlay 1, protective seam 2, superpolymer hologram recording material and enhancement layer 4 is compound successively constitutes, as shown in Figure 1; The light that described angular color change layer 20 is made up of separation layer 22, angular photochromic material becomes pattern functional layer 23, separation layer 24, tack coat 26 is compound successively constitutes, as shown in Figure 2; Reflection holography layer 10 connects to form the composite anti-fake film with angular color change layer 20 by articulamentum 5, sees shown in Figure 3.
Among the present invention, in the described angular color change layer 20, as required, between separation layer 24 and tack coat 26, also dyed layer 25 can be set.
Among the present invention, before reflection holography layer 10 and angular color change layer 20 were compound, the former downside also was provided with a release layer 6, so that articulamentum 5 is protected, the latter's upside also is provided with a protective seam 21, so that separation layer 22 is protected.
Among the present invention, articulamentum 5 can adopt adhesivess such as polyacrylic or Polyurethane rubber.
Described overlayer 1 can adopt membraneous materials such as polyethylene terephthalate (PET) film, Biaxially oriented polypropylene (BOPP) film or tygon (PE) film.
Described protective seam 2 can adopt the material or the photopolymer binder of esters of acrylic acid.
Described enhancement layer 4 is used to strengthen the brightness and the visual field of reflection hologram.
Described separation layer 22,24 is used for the defencive function layer; its material can adopt prepolymer and trimethylolpropane tris acrylic acid ester monomer or aliphatic urethane diacrylate, the epoxy acrylate etc. of amino acrylates class; coat the surface of functional layer, to prevent penetrating of functional layer.
Described dyed layer 25 can add as required.
Described tack coat 26 can adopt pressure sensitive adhesive, also can adopt hot melt adhesive.
Among the present invention, described reflection hologram functional layer 3 is made of compositions such as photographic layer, monomer, light-initiated systems.Wherein, photographic layer is a refractive index film forming matter within the specific limits.Described angular color change functional layer 23 is that a kind of components such as photoinitiator, cellulose derivative and polymerisable monomer that contain are by being polymerized.See Chinese patent 021374732 and 021369747.
The preparation method of false proof laminated film of the present invention is as follows: prepare hologram layer 10 and angular color change layer 20 respectively earlier, carry out compound then.Prepare hologram pattern 3 in the photographic layer inside of method in hologram layer 10 by reflection record on the composite bed at last.Wherein, hologram layer 10 is made up of refractive index film forming matter within the specific limits; preparation can be adopted the method for patent 021374732: compositions such as monomer, light-initiated system are joined in the solvent under red light; be mixed to dissolving with magnetic agitation; coat (as PET, PE, OPP etc.) on the plastic foil; in temperature is that drying makes in 65～75 ℃ the drying box, goes up enhancement layer then again, and protective seam and overlayer get final product.The preparation of angular color change layer 20 can be adopted the method in the patent 021369747.With photoinitiator (as: isobutyl benzoin ether, 2,4,6-trimethylbenzene formyl hexichol phosphine oxide, 1-hydroxy cyclohexyl phenylketone, 2,2-dimethyl-2-phenyl acetophenone etc.) be mixed in the solution of cellulose derivative and polymerisable monomer and dissolve, after decompression is taken out and is desolvated, obtain jelly, jelly is coated on the base material, pass through the magnetic field of 0.5～5.0T under the room temperature, then under the radiation of ultraviolet light, solidify, obtain having angular color change pattern 23, separation layer 22 and 24 is gone up promptly more again in its both sides.20 on reflection holography layer 10 and angular color change layer compound can be finished also and can be finished by the compound technology of heat by laminating technology by articulamentum 5.
To have the reflection hologram template is fixed on the optical table, the directional light of identical incident angle (becoming 30 ° of-80 ° of angles with the dry plate normal) is a reference light during with logging template H2 with coherent light, the recording sheet that reflection holography recording layer and angular color change patterned layer is compound contacts with template by the dimethylbenzene matching fluid, form evenly about 2-6 μ dimethylbenzene optically coupled layers, under the irradiation of reference light, in thin layer, write down reflection holography Fig. 3.The photopolymer film obtains a reflection holography Fig. 3 who contains the angular color change pattern through photocuring and hot enhancement process.
The composite anti-fake film that the present invention proposes can seen two kinds of patterns by translation-angle under the light source usually, and one is to observe holographic three-dimensional pattern under the light of certain angle; Another tool is that the angular color change pattern or the literal on surface transfers green to by golden red behind rotational angle.Therefore, the present invention proposes anti-counterfeiting power, this film can be used as false proof Jianzhen's sign, driving license, identity document, credit card, reaches the covering of all kinds of documents etc.
