The specific embodiment
The manufacture craft of a kind of roll type holographic pattern of the present invention film; Its principle is: the characteristic of utilizing holographic pattern microcosmic groove structure accurately to be duplicated; Utilize the information transfer layer to duplicate the holographic pattern groove structure on female film surface; Formation has the transfer membrane of the microcosmic groove structure of the holographic pattern that is replicated, and utilizes this transfer membrane to make the holographic pattern film again.The holographic pattern of female film then is retained in female film.On technology, when making the holographic pattern film, realized having substituted imprint process of the prior art with coating process, improved production efficiency greatly, provide cost savings.
Accurately duplicate requirement for what reach the holographic pattern groove structure; The application is in manufacture craft; The selection of layers of material and the technological parameter of layers of material are all optimized, both improved production efficiency, what is more important is in follow-up technology; Guaranteed the accuracy that the holographic pattern groove structure duplicates between each layer; Well arranged, the Stability Analysis of Structures of the groove structure that duplicates under the above-mentioned technological parameter, accuracy of repetition is high, thereby visually is presented as the high accuracy of female film holographic pattern is duplicated.
Specifically, as shown in Figure 5, the surface of female film 1 has holographic pattern groove structure 2, and vapor deposition information transfer layer 4 on female film surface, and evaporation process is following: in vacuum evaporation plating machine, vacuum is lower than 10
-2Millibar, speed 60-1000m/min.Utilize the characteristic that can accurately be duplicated between structure sheaf of holographic pattern microcosmic groove structure, above-mentioned groove structure 2 is copied to information transfer layer 4 accurately.Having this kind layer constructed products and can be referred to as transfer membrane, is the basis of carrying out subsequent technique of the present invention.
Coating adhesive adhesion coating on the information transfer layer 4 of transfer membrane carries out itself and paper tinsel film compoundly again, and combination process is following: in compounding machine, and 80-150 ℃ of oven dry, be 10-60 second drying time, operating speed is 20-150m/min.Female film is peeled off, can be obtained the holographic pattern film.After peeling off, attached on the paper tinsel film, because information transfer layer 4 is the holographic pattern groove structures 2 on the female film that duplicates, therefore, this holographic pattern film has also promptly been realized duplicating holographic pattern on female film to information transfer layer 4 with adhesive layer.And female film of this moment still also remains with complete holographic pattern, can continue to use and carry out follow-up technology.
As a kind of improvement, can apply a transfer layer between female film 1 and the information transfer layer 4, thereby make that duplicating with transfer effect of female film surface hologram groove groove structure is more superior.Transfer layer adopts coating machine to be applied to wet amount 1-20 gram/m
2,, 80-200 ℃ of oven dry, be 10-60 second drying time, operating speed is 20-150m/min.
Improve as another kind; On the basis that makes above-mentioned holographic pattern film, above-mentioned can also further being improved to: surface-coated second protective layer at the holographic pattern film, carry out itself and film compound again; After compound film is peeled off the holographic pattern film that is improved.Because it is not through multiple membrane process, so its surface do not have minute surface (face) effect that traditional transfer membrane technology is had, and this is a weak point of utilizing the holographic pattern film that this technology makes.So the information transfer layer not only has the holographic pattern groove structure identical with female film; And grating is just full; Groove structure is stable, well arranged, and this new holographic figure line film can reach face (minute surface) effect after the same transfer of the holographic pattern film that makes with traditional transfer membrane technology.
Female film among the present invention adopts female film commonly used on the market to get final product; Preferred surface has the roll type film of holographic pattern groove structure or the composite membrane of metal forming or film and metal forming; Because its surface grating is full, groove structure is more stable, more helps realizing accurately duplicating of groove structure.And the female film of roll type is applicable to and the continuity production application of large molded machine, coating machine, compounding machine can improves efficiency of operation greatly.Female film commonly used on the market mainly contains following two kinds of structures.A kind of is the female film with double-layer structure, promptly comprises paper tinsel rete, Information Level, and wherein the information layer surface impression has holographic pattern.Therefore, from microcosmic, female film surface promptly has the groove structure of holographic pattern, thereby can realize duplicating this groove structure.And another kind has three-decker, i.e. paper tinsel rete, Information Level, information protection layer, and wherein the information layer surface impression has holographic pattern.Above-mentioned paper tinsel rete; Can be selected from the composite membrane of PET film, BOPP film, PI film, PC film or metal forming or above-mentioned film and metal forming; Metal forming wherein; Then can be all kinds of common metal paper tinsels of aluminium foil, Copper Foil or the like, as long as processing requests such as Information Level adhesion-tight, the follow-up heatproof stretch-proof of adaptation all can.For carrying out compound paper tinsel film,, can also select to use chemical films except selecting for use the above-mentioned material with female film.Chemical films described here is meant with plastics to be that substrate surface is through chemically treated plastic sheeting.
