Description
Technical Field
The invention relates to a film, in particular to a film containing a strippable supporting layer, which can be applied to the technical field of anti-counterfeiting.
Background
The present photosensitive film is mainly composed of film base and photosensitive material layer, the film base is made up by using transparent film, the photosensitive material layer is mainly formed from silver halide and several colour couplers, and the photosensitive material can be directly coated on the film, and can be passed through the processes of exposure, development and fixation so as to implement the production of colour picture. The photosensitive film is mainly applied to motion picture films, slides, projection films, X-ray films and the like, and has very few applications in other fields, particularly in the field of anti-counterfeiting technology.
In the production and use of the above-mentioned photosensitive film, since there are processes of coating, sensitization, development, slitting, adhesion, etc., such a photosensitive film is usually not less than 80 μm in thickness in order to ensure dimensional stability and workability of each process. However, in the field of anti-counterfeit technology, some special products, such as jewelry, fine objects, watches, spectacle frames, etc., require small and thin anti-counterfeit marks, for example, the thickness does not exceed 10 μm, and the area requirement is as small as 2mm2In the following, and the identification is completed by one-time shooting, it is obvious that the photosensitive film cannot meet the application of the anti-counterfeiting mark, and the prior art for such a requirement does not provide a solution yet, and needs to be solved urgently.
Disclosure of Invention
The invention aims to provide a film containing a strippable supporting layer for manufacturing a small and thin anti-counterfeiting mark, which can meet the dimensional stability and processability in the processes of coating, sensitization, developing, cutting, adhesion and the like, and can obtain a thin film body after the supporting layer is stripped, and the anti-counterfeiting mark manufactured by using the thin film body has a small area, such as less than 2mm2The thickness of the anti-counterfeiting mark can be very thin, for example, the thickness can not exceed 10 mu m, and the technical problem that the anti-counterfeiting mark is small and thin in special products such as jewelry, exquisite articles, watches, spectacle frames and the like in the market can be solved.
The purpose of the invention is realized as follows:
a film, the film comprises a film layer and a pattern making material layer, and is characterized by further comprising a peelable support layer.
Preferably, the pattern making material layer is a photosensitive material layer, and the photosensitive material can form a pattern through photosensitive development; alternatively, the patterning material layer is a photolithographic material layer, and the photolithographic material can be patterned by laser photolithography.
Preferably, the film layer is located between the support layer and the patterning material layer.
Preferably, the supporting layer, the film layer and the pattern making material layer are arranged from top to bottom in sequence.
Preferably, the photosensitive material layer has at least two layers, and the photosensitive material of each photosensitive material layer is different.
Preferably, a release layer and a first adhesive layer are further arranged between the supporting layer and the film layer from top to bottom.
Preferably, a shielding layer is further attached to the upper surface or the lower surface of the thin film layer.
Preferably, in use, the first adhesive layer has an adhesion force with an adherend to which the first adhesive layer is adhered of not less than 100 g.
Preferably, the attached object is an anti-counterfeiting object or a package of the anti-counterfeiting object.
Preferably, a texture layer is further included between the film layer and the patterning material layer.
Preferably, the upper surface of the patterning material layer is further provided with a texture layer.
Preferably, an adhesive layer II is further arranged between the supporting layer and the film layer.
Preferably, the peeling force between the second adhesive layer and the film layer is less than 50 g.
Preferably, the adhesive layer two is attached to the support layer when the film layer is peeled from the support layer. Preferably, the photolithographic material is a dark coating, a light coating or a white coating.
Preferably, the barrier layer contains TiO2。
The beneficial effects of the invention are very obvious, which are as follows:
1. the invention develops a film of an ultrathin and ultra-small anti-counterfeiting mark which can be applied to the anti-counterfeiting technical field for the first time, can meet the dimensional stability and the processability in the processes of coating, sensitization, developing, cutting, adhering and the like, and the film comprises a strippable supporting layer, and a very thin film body can be obtained after the supporting layer is stripped.
2. The ultrathin film body can be obtained after the supporting layer is peeled off, and the ultrathin and ultrathin anti-counterfeiting mark manufactured by the ultrathin film body is difficult to recover and counterfeit by a counterfeiter, because the counterfeiter is difficult to completely transfer the ultrathin and ultrathin anti-counterfeiting mark from an attached object, and because the ultrathin and ultrathin anti-counterfeiting mark is extremely easy to damage in the transferring process of the counterfeiter, the anti-counterfeiting effect is greatly enhanced.
3. The ultrathin film body is adhered to the surface of a material, such as a paper surface, a metal surface, a plastic film surface and the like, and because the ultrathin film body is ultrathin (generally not more than 6 mu m), the surface of the material after being adhered does not have concave-convex hand feeling, is attractive and difficult to fall off, and the ultrathin film body can be used for manufacturing an ultrathin and ultrathin anti-counterfeiting mark, for example, the area of the anti-counterfeiting mark is less than 2mm2The thickness is not more than 10 mu m, so the anti-counterfeiting mark can be adhered on the surface of the packing material before the printing processing of the packing material without influencing the printing processing of the packing material, compared with the traditional processing technology of firstly printing the packing material and then labeling the anti-counterfeiting mark on the printed packing material, the manufacturing cost is greatly reduced because the traditional mode of firstly printing and then labeling, a production company of anti-counterfeiting products needs to firstly send the packing material to each printing factory for printing, after the printing is finished, the printed packing material is packaged by each printing factory and then is sent to a labeling company, the labeling company unpacks and then pastes the anti-counterfeiting mark, the processing technology of firstly labeling and then printing only needs the production company of the anti-counterfeiting products to firstly send the packing material to the labeling company, firstly labels and then sends the packing material to each printing factory for printing, thereby one procedure of unpacking and printing the packed and printed packing material is saved, and production of counterfeit-proof productsThe label pasting machine has the advantages that a company only needs to butt joint one label pasting company, and does not need to butt joint a plurality of printing factories and the label pasting company like a traditional processing technology of firstly printing and then labeling, so that the efficiency is greatly improved, the operation cost and the management cost are greatly reduced, especially in the process of mass production, the effect is particularly remarkable, and the label pasting machine has great significance for improving the printing, processing and production management mode.
