Description
Technical field
The utility model relates to a kind of hot transfer printing and uses fluorescence membrane; Specifically; Relate to a kind of light-emitting film that can be used for hot transfer printing based on organic fluorescence materials, it can be surperficial with color fluorescence pattern transfer to most of solid dielectric through the mode of hot transfer printing, like plastics, paper, glass etc.
Background technology
Now, fluorescence falsification preventing has become institute of businessman and has often adopted one of false proof means, but simultaneously, its application limitation is still quite big.Specifically:
At first be that color is single, present common fluorescence falsification preventing label is just accomplished monochromatic false proof mostly, like the blue-fluorescence coding on Chinese cigarette surface;
Next is an application difficult, fluorescence falsification preventing is applied to must fluorescent material be processed printing ink among the product, but will the fluorescent ink that disposed be added in the ready-made printing process, should use the comparison difficulty; With the offset press is example, and nowadays best offset press is eight look machines, expensive, but itself need the color of printing generally just to have five or six kinds, and what that is to say the anti-forgery ink that can be used for printing has only two or three kind, quite big to the color limitation; In addition, because the invisibility of fluorescent ink itself, the duplet version also is a difficult point;
The 3rd is that the false proof ageing resistance of organic fluorescence is poor, and as in the ordinary course of things, organic fluorescence is red will to fade about one month in periods of direct sunlight; But use inorganic fluorescent material, because it is insoluble to printing ink, printing applicability and printing effect can be very poor.
Up to now, this area is still untapped goes out a kind of novel fluorescence product that can solve above-mentioned prior art problems.
Therefore, this area presses for and develops a kind of novel fluorescence product that can solve above-mentioned prior art problems.

Description of drawings
Fig. 1 is the structural representation of the hot transfer printing of the utility model with fluorescence membrane.
Fig. 2 shows the hot transfer printing of the utility model and uses with the transfer printing of fluorescence membrane.
The specific embodiment
The inventor of the utility model finds after having carried out extensive and deep research; Through using the structure of release layer and fluorescence adhesive layer; Phosphor pattern is wrapped in middle; And said structure is applied to hot transfer substrate film, fluorescence membrane is used in the hot transfer printing that can obtain having overcome the defective of above-mentioned prior art.Based on above-mentioned discovery, the utility model is accomplished.
The utility model provides the hot transfer film based on multiple organic fluorescence materials, and these fluorescent materials can be excited by ultraviolet light, visible or infrared light, and sends visible fluorescence to the infrared wavelength interval, and the color of being sent out can be red, and is green, indigo plant, Huang etc.These fluorescent materials are applied to hot transfer film, can obtain hot transfer printing and use fluorescence membrane.
The utility model provides a kind of fluorescence heat transfer film, and it is formed by three layers, and said three layers is base film, release layer and fluorescence adhesive layer successively.
In the utility model, the base material of being selected for use is generally PET (PET) material; Release layer is generally and keeps solid state at normal temperatures, and bonding force diminishes at a certain temperature, breaks away from from basalis very soon; The key property of fluorescence adhesive layer is with the stock surface higher bonding force to be arranged, and guarantees that printed layers combines firmly with the stock surface.Simultaneously, should select different adhesives according to different stocks.
In the utility model, said fluorescence adhesive layer comprises any solubilized organic fluorescence materials and does not influence the printing ink and the adhesive of printing applicability, for example toluene-butanone system gravure ink.
Below in conjunction with accompanying drawing the utility model is done further to describe, it should be understood that, they only are used to the utility model is described and are not used in the scope of restriction the utility model.
Fig. 1 is the structural representation of the hot transfer printing of the utility model with fluorescence membrane.As shown in Figure 1; Said hot transfer printing is made up of base film 1, release layer 2 and fluorescence adhesive layer 3 with fluorescence membrane, and it can prepare through following steps: the first step, at base film surface coated mould release; Because solvent evaporates rapid speed in the mould release; So in coating process, note controlling viscosity, promptly control the solid content of mould release; Note the transparency of mould release simultaneously, not so can influence the effect of printed layers; The coating thickness of mould release is controlled at about 5 microns; Second step directly was dissolved in adhesive with fluorescent material, and the mode of adhesive through gravure or flexo is printed in base film surface (release layer surface); According to the complexity of printed pattern, can select multiple fluorescent ink for use, as red; Indigo plant, green, Huang etc.; If pattern has certain complexity, need to adopt the ultraviolet source of 365-405nm to carry out to version.
Fig. 2 shows the hot transfer printing of the utility model and uses with the transfer printing of fluorescence membrane.As shown in Figure 2; The forming hot transfer printing by base film 1, release layer 2 and fluorescence adhesive layer 3 and can printed phosphor pattern be needed on printable fabric 5 surfaces through hot transfer apparatus (comprise hot glue roller 6 with heating plate 7) of gained with fluorescence membrane; Wherein said printable fabric can comprise the solid carrier that need carry out fluorescent printing, for example plastics, paper, fabric, glass, pottery and metal etc.
The major advantage of the utility model is:
At first; Because the phosphor pattern on the heat transfer film can print through the mode of gravure or flexo; Its color can be not limited to the restriction of equipment; Thereby can print more complicated or colorful pattern, but in theory once the kind of printing color can comprise the fluorescent ink of existing any color;
Secondly, use easy, now; Client such as need are printed the fluorescence falsification preventing pattern on certain product of oneself, the product of must will undertaking the printing of offers fluorescent printing producer and prints again, perhaps oneself invest fluorescent printing equipment and print; These two kinds of schemes all will significantly improve product cost, and after adopting corresponding fluorescence heat transfer film, producer only needs to the client hot transfer film to be provided; The client only need use hot transfer apparatus simple to operate; Just can be with required fluorescence falsification preventing pattern seal to any self required carrier surface that carries out fluorescent printing, its operation is very simple, and cost is also very cheap;
At last, because in the thermal transfer printing process, its adhesive layer and release layer have played the effect of secluding air in the middle of phosphor pattern is wrapped in indirectly, will reduce the ageing process of fluorescent material greatly, can significantly improve the service life of fluorescent material.
Further set forth the utility model below in conjunction with concrete embodiment.But, should be understood that these embodiment only are used to the utility model is described and do not constitute the restriction to the utility model scope.The test method of unreceipted actual conditions in the following example, usually according to normal condition, or the condition of advising according to manufacturer.Except as otherwise noted, all percentage and umber are by weight.
