Description
Technical Field
The present invention relates to a transfer film, and more particularly to a transfer film capable of generating a specular reflection effect; the invention further relates to an application of the transfer printing film, in particular to an application of the transfer printing film to a plurality of targets made of different materials.
Background
With the increasing living standard, people not only pursue the inherent quality of the product, but also more concentrate on the appearance of the product to show personal taste and uniqueness. Among them, in order to properly show the sense of quality of production, it is a common practice to improve the glossiness or brightness of products by plating films, and to promote the development of mirror surface decoration technology.
Current mirror decoration techniques include water electroplating, vacuum electroplating, water transfer printing and spray coating. However, the water electroplating generates a large amount of metal waste liquid, which is easy to cause environmental protection problems; the vacuum plating equipment is relatively expensive, the process is complex, and the cost is high; the problems of film breakage and large amount of wastewater pollution are easy to occur in water transfer printing; the application of spray coating is limited, and in addition to the requirement that the target object itself has high flatness to enable the sprayed particles to show the mirror surface effect after being stacked, the mirror surface reflection effect can be shown by improving the flatness by spraying multiple layers of coatings on the target object, so that the mirror surface decoration effect achieved by spray coating is also high in cost.
Based on the defects of the conventional water electroplating, vacuum electroplating, water transfer printing and spraying, the prior art develops a transfer printing film which sequentially comprises a base material, a mirror-like release layer and a highlight layer from bottom to top, and by means of the technical means of arranging the mirror-like release layer between the base material and the highlight layer, after a user applies the transfer printing film to a target object to be transferred, the highlight layer can be attached to the surface of the target object, and the highlight layer is smoothly separated from the mirror-like release layer and the base material, so that the highlight layer is transferred to the surface of the target object, and the mirror reflection effect can be displayed.
However, when the prior art attempts to decorate the surface of the target object by using the transfer film, it is found that the mirror-like release layer is provided to facilitate the releasing of the highlight layer from the substrate and the transfer of the highlight layer onto the surface of the target object, but the mirror-like release layer has a certain thickness, which is not easy to adhere to the surface of the decorated target object during the heating, stretching and pressure forming process, and inevitably generates ripples or orange peel, which all result in that the mirror-like release layer and the highlight layer transferred onto the target object cannot exhibit the originally expected mirror reflection effect, so that there is a need for improvement.
Disclosure of Invention
In order to overcome the disadvantages of the prior art, the present invention provides a transfer film and the use thereof, which can omit the use of a mirror-like release layer, and can smoothly provide a mirror reflection effect to a transferred target object after the transfer film is transferred to the surface of the target object.
In order to achieve the above object, the present invention provides a transfer film, including: the substrate is provided with a joint surface, the highlight layer is provided with a mirror surface and a joint surface which are opposite, the mirror surface of the highlight layer is in direct contact with the joint surface of the substrate, the arithmetic average roughness of the joint surface of the substrate is less than 1.5 micrometers, the material of the substrate comprises a polyethylene composition, the polyethylene composition is provided with hydroxyl groups (hydroxyl groups, -OH groups), and the material of the highlight layer comprises polymethyl methacrylate.
Through the technical means, the transfer printing film can be separated from the base material conveniently only by arranging the mirror-like release layer in the prior art, and has expected mirror reflection effect. In other words, the high-light-emitting layer of the present invention can be favorably attached to the surface of the object after transfer, and can also provide the object with a specular reflection effect.
The mirror surface and the binding surface of the high light layer are made of the same material, have high light characteristics and can show mirror reflection effect, and the binding surface is used for further binding to a target object.
In the present specification, the phrase "the mirror surface of the highlight layer is in direct contact with the bonding surface of the substrate" means that no mirror-like release layer as in the prior art is additionally disposed between the highlight layer and the substrate in the transfer film.
Preferably, the arithmetic mean roughness of the bonding surface of the substrate is less than 1.2 microns; more preferably, the arithmetic mean roughness of the bonding surface of the substrate is less than 1 micron; still more preferably, the arithmetic mean roughness of the bonding surface of the substrate is less than or equal to 0.8 μm. In one embodiment, the arithmetic mean roughness of the bonding surface of the substrate is greater than or equal to 0.05 microns and less than or equal to 0.2 microns. The invention can maintain the surface characteristics of the mirror surface of the highlight layer when the mirror surface of the highlight layer is directly contacted with the bonding surface of the substrate by controlling the arithmetic average roughness of the bonding surface of the substrate.
Preferably, the substrate has a Machine Direction (MD) elongation at break of 300% to 600% and a Transverse Direction (TD) elongation at break of 300% to 600%. More preferably, the substrate has a machine direction elongation at break of 375% to 525% and a cross direction elongation at break of 375% to 525%. Still more preferably, the substrate has a machine direction elongation at break of 400% to 500% and a cross direction elongation at break of 400% to 500%. Accordingly, the transfer film can be applied to not only flat surfaces with large areas, but also targets with different detailed structures or concave-convex wavy surfaces.
Preferably, the polyethylene composition in the material of the substrate may be modified polyethylene having a plurality of hydroxyl groups, and the modified polyethylene may comprise a repeating unit of formula I and/or formula II as follows:
wherein n1 is a natural number greater than or equal to 0 and less than 5000, and n2 is a natural number greater than 0 and less than 5000.
When n1 is 0, the polyethylene composition in the material representing the substrate comprises only repeating units of formula II, i.e. the repeating units of the polyethylene composition consist of formula II.
Preferably, n1 is a natural number from 0 to 3000.
Preferably, n2 is a natural number between 1000 and 4000.
Preferably, the polyethylene composition has a degree of polymerization of 2000 to 3000. More preferably, the polyethylene composition has a polymerization degree of 2300 to 2600.
The material of the substrate may further comprise a plasticizer, and the content of the plasticizer is 8 to 13 weight percent based on the total weight of the material of the substrate. Preferably, the plasticizer is present in an amount of 9 to 12 wt%, based on the total weight of the base material.
In this specification, the highlight layer has a high gloss characteristic, and after the highlight layer of the transfer film is transferred to a target object, the surface of the target object exhibits a macroscopic specular reflection effect. The glossiness of the mirror surface of the highlight layer is greater than or equal to 80 GU. In one embodiment, the specular surface of the highlight layer has a reading value of 90GU to 100GU as measured by a 60-degree gloss meter. In another embodiment, the specular surface of the highlight layer has a reading of greater than or equal to 85GU to 95GU as measured by a 20 degree gloss meter. In another embodiment, the specular surface of the highlight layer has a reading of greater than or equal to 95GU to 105GU as measured by an 80 degree gloss meter.
Preferably, the polymethyl methacrylate (PMMA) is polymethyl methacrylate oligomer (PMMA oligomer).
Preferably, the material for forming the high-light layer may include a solvent such as Methyl Ethyl Ketone (MEK), Butyl Acetate (BAC), Ethyl Acetate (EAC), and 1-hydroxy cyclohexyl phenyl Ketone (TBO 184), but is not limited thereto. The invention adopts butanone as a solvent, is beneficial to uniformly dispersing polymethyl methacrylate, and can coat a highlight layer on a substrate.
The material for forming the high-gloss layer may be added with a cross-linking agent or an ultraviolet curing glue (for example, an ultraviolet curing resin such as urethane acrylic resin or modified epoxy acrylic resin) so that the high-gloss layer is cured and fixed to a target object made of a material such as plastic or metal after being irradiated with ultraviolet rays, without an additional adhesive layer for bonding the target object and the high-gloss layer. In one embodiment, the energy range of the UV radiation can be 500mJ/cm2To 1800mJ/cm2(ii) a In another embodiment, the energy range of the UV irradiation can be 500mJ/cm2To 1500mJ/cm2。
The thickness of the substrate may be 30 to 100 micrometers; preferably, the thickness of the substrate may be 20 to 100 micrometers.
The thickness of the high light layer can be 10 micrometers to 100 micrometers; preferably, the thickness of the high light layer can be 10 to 50 micrometers; more preferably, the thickness of the highlight layer may be 15 to 50 micrometers. The invention can improve the brightness and the mirror reflection effect of the light-raising layer by increasing the thickness of the light-raising layer.
The invention also provides an application of the transfer printing film, which comprises applying the transfer printing film on a target object. Therefore, after the transfer printing film is transferred to the target object, the appearance of the target object can be endowed with a visual effect of mirror reflection through the highlight layer of the transfer printing film.
Specifically, after the transfer film is applied to the surface of an object, the bonding surface of the highlight layer of the transfer film is bonded to the surface of the object, and the substrate of the transfer film can be peeled off from the mirror surface of the highlight layer.
In one embodiment, after the highlight layer of the transfer film contacts the surface of the target, the transfer film may be heated at a temperature of 50 ℃ to 120 ℃ to soften the highlight layer, and a pressure of 1.0atm to 4.0atm is applied to facilitate the transfer film to wrap the target, and then the polymethyl methacrylate is caused to perform a crosslinking reaction by ultraviolet rays to be hardened and fixed to the target. The invention can be separated from the high gloss layer solidified and fixed on the object without a release layer, and does not affect the mirror reflection effect of the high gloss layer because the arithmetic average roughness of the substrate joint surface is very small (smaller than the arithmetic average roughness of the object surface).
According to the invention, the binding surface of the high-light layer of the transfer printing film is directly bound to the surface of the target object, and the high-light layer and the target object are bound without additionally arranging an adhesive layer. In other words, the surface of the target directly contacts the bonding surface of the highlight layer without an adhesive layer.
According to the present invention, the material of the target may be selected from the group consisting of: plastic, metal, and glass, but not limited thereto.
Preferably, the plastic includes Polycarbonate (PC), polypropylene (PP), Polyester (PET), polyethylene terephthalate (ABS), Polyurethane (PU), or thermoplastic elastomer (TPE), but not limited thereto.
According to the invention, the target may be selected from the group consisting of: the mobile phone, the tablet computer, the protective shell, the household appliance, the automobile, the makeup and maintenance product, the ornament and the decorative plate, but not limited to the above.
In one embodiment, the surface of the target may be a flat surface or a curved surface.
In another aspect, the target has a protrusion or a recess, and any one of the length, width and height of the protrusion or recess is less than 500 mm. Preferably, any one of the length, width and height of the convex or concave portion is more than 0 mm to 100 mm.
The adhesion surface of the high-light layer of the transfer film is directly adhered to the convex portion and/or the concave portion of the target.
The transfer film of the invention has good ductility, so that objects with different sizes can be arbitrarily applied.
If the mirror decoration is required for a large-area target, for example: the length and/or width of the surface of the target object can be more than 1.5 meters on the outer surface of the whole automobile; preferably, the length and/or width of the surface of the target is greater than 2 meters; more preferably, the surface may have a length and/or width greater than 2 meters and less than 5 meters.
If the mirror decoration is required for a small area of the target, for example: a handset housing or an accessory, the length and/or width of the surface of the object may be less than 500 mm; preferably, the length and/or width of the surface may be greater than or equal to 0.1 mm to less than or equal to 200 mm.
In summary, the transfer film of the present invention not only can solve the technical defects of the conventional water electroplating, vacuum electroplating, water transfer printing and spraying, but also can omit the limitation that the conventional transfer film needs to use a release layer, a mirror layer or a mirror-like release layer, so as to ensure that the surface of the target has the mirror reflection effect after the transfer film is applied to the target, and improve the aesthetic property and functionality of the target. In addition, the transfer film of the present invention can be applied to various targets, such as metal targets, and thus has a wide application range and excellent market potential.

Detailed Description
The technical solutions of the present invention will be described in detail below in order to clearly understand the technical features, objects, and advantages of the present invention, but the present invention is not limited to the practical scope of the present invention.
Several examples are provided below to illustrate embodiments of the present invention; those skilled in the art can readily appreciate from the disclosure of the present invention that the advantages and features of the present invention may be realized and attained by various modifications and changes without departing from the spirit and scope of the invention.
Transfer printing film
As shown in fig. 1, the transfer film 10 includes a substrate 100 and a highlight layer 110 disposed on the substrate 100, the substrate 100 has a bonding surface 101, the highlight layer 110 has a mirror surface 111 and a bonding surface 112 opposite to each other, the mirror surface 111 of the highlight layer 110 is in direct contact with the bonding surface 101 of the substrate 100, an arithmetic mean roughness of the bonding surface 101 of the substrate 100 is less than 1.5 μm, a material of the substrate 100 includes a polyethylene composition, and a material of the highlight layer 110 includes polymethyl methacrylate.
The transfer film 10 can be applied to various different types of objects, thereby giving the objects a specular reflection effect; the target is, for example: compact case, ornaments, mobile phone, tablet computer, protective shell, household electrical appliance, building materials, kitchen ware, automobile, decorative plate, etc., but not limited thereto.
In one embodiment, the target may be a compact case. After the transfer film is applied to the compact case, as shown in fig. 2A, the surface 201 of the compact case is a curved surface, and the surface 201 of the compact case is attached to the attaching surface 112 of the highlight layer 110, so that the appearance of the compact case presents a visual effect of mirror reflection through the highlight layer 110.
In another embodiment, the object may be an article, as shown in FIG. 2B, having a large area surface 202 and a small area surface 203; after the transfer film is applied to the ornament, the large-area surface 202 and the small-area surface 203 of the ornament are attached to the highlight layer 110, so that the entire appearance of the ornament can have a mirror reflection visual effect through the highlight layer 110. Although the width of the small-area surface 203 is only 3 mm, the highlight layer 110 can still be well attached to the small-area surface 203 without wrinkling, thereby improving the texture and fineness of the overall appearance of the ornament.
In yet another embodiment, the target may be a mobile phone, and as shown in fig. 2C, a protrusion 2011 (e.g., a camera lens) may be disposed on the mobile phone; after the transfer film is applied to the mobile phone, the convex 2011 region of the mobile phone is not attached to the highlight layer 110, so the highlight layer 110 in the region is taken away by the substrate 100 during peeling, thereby leaving the position of the camera lens free, and enabling the subsequent mobile phone lens to be directly assembled. Although the height of the protrusion 2011 is only 0.5 mm, the highlight layer 110 can still be well attached to the side of the protrusion 2011 without wrinkling, and the overall appearance of the protrusion 2011 can show a mirror reflection effect when viewed from different angles, thereby improving the texture and fineness of the overall appearance of the mobile phone.
In another embodiment, the target may be a tablet computer, and as shown in fig. 2D, a recess 2012 may be formed in the tablet computer. After the transfer film is applied to the tablet computer, the vent holes 2013 disposed on the concave portion 2012 can further improve the adhesion effect of the light-raising layer 110 being sucked to the concave portion 2012 by a vacuum-pumping manner, so that the concave portion 2012 of the tablet computer can be closely attached to the highlight layer 110, and the entire appearance of the tablet computer can show a mirror reflection visual effect through the highlight layer 110. Although the depth of the concave part 2012 is only 2 mm, the high gloss layer 110 can still be well adhered to the concave part 2012 without wrinkling, and the overall appearance of the concave part 2012 can show a mirror reflection effect when viewed from different angles, thereby improving the texture and fineness of the overall appearance of the tablet computer. According to different product requirements, the target 20 may have a plurality of recesses 2012, and the recesses 2012 may constitute a trademark.

Comparative example 1: the transfer film of comparative example 1 has a substrate, a mirror-like release layer, and a highlight layer, wherein the substrate is a commercially available polyolefin film (i.e., PO film) including Polyethylene (PE) and polypropylene (PP).
Comparative example 2: the transfer film of comparative example 2 has a substrate and a highlight layer, wherein the substrate is a commercially available product, the material is a polyethylene terephthalate film (i.e., PET film), the elongation at break thereof is 75%, and the highlight layer is the same as in example 1.
Application of transfer printing film
Examples 2 to 4 are all applications of the transfer film of example 1, and the transfer film of example 1 is transferred to a metal object (example 2) on which ink is printed, to a plastic object (example 3) on which ink is printed, and to a plastic object (example 4) on which ink is not printed, respectively.
Comparative examples 3, 5 and 7 are applications of the transfer film of comparative example 1, and the transfer film of comparative example 1 is transferred to a metal object printed with ink (comparative example 3), a plastic object printed with ink (comparative example 5) and a plastic object not printed with ink (comparative example 7), respectively.
Comparative example 4, comparative example 6, and comparative example 8 are applications of the transfer film of comparative example 2, and the transfer film of comparative example 2 is transferred to a metal object (comparative example 4) on which ink is printed, to a plastic object (comparative example 6) on which ink is printed, and to a plastic object (comparative example 8) on which ink is not printed, respectively.
Comparative test for application of transfer film
As shown in fig. 3, the transfer efficiency of the transfer film applied to the targets (housings) of different materials and the transfer areas of the transfer film in examples 2 to 4 and comparative examples 3 to 8 was evaluated by visually observing the transfer yield of the highlight layer 110 of the transfer film and the visual effect thereof in the different transfer areas. The object has a first transfer region 21, a second transfer region 22 and a third transfer region 23, the first transfer region 21 being a major surface (i.e. the largest surface) of the object and having an area size of about 130cm 2; the second transfer region 22 is a side surface of the object and has an area size of about 24cm 2; the third transfer area 23 indicates the surface of the object bottom, and the third transfer area 23 is parallel to the first transfer area 21, and the area size is about 4.8cm2, and the results are shown in table 1.
Table 1: transfer printing effect of each transfer printing film in different transfer printing areas after transfer printing to each surface of target object
O: showing the mirror reflection effect after the transfer of the target object.
And (delta): representing a transfer yield of 30% to 60% or the occurrence of waving or orange peel.
X: indicating that the transfer yield was less than 30% or that the adhesive failed.
First, it is understood from the embodiments 2 to 4 that the transfer effect of the transfer film of the embodiment 1 is not affected regardless of the material of the target object, such as metal or plastic, and the entire appearance of the target objects of the embodiments 2 to 4 can exhibit the visual effect of mirror reflection.
Second, it is clear from the embodiments 3 and 4 that the transfer effect of the transfer film of the embodiment 1 is not affected regardless of whether the surface of the object is coated with ink, and the entire appearance of the objects of the embodiments 3 and 4 can exhibit the visual effect of specular reflection.
Thirdly, as can be seen from the data of comparative examples 3, 5 and 7, the transfer yield in the third transfer area was only 30% to 60% or the moire or orange peel appeared, which indicates that when the PO film was used as the base material, the increase of the mirror-like release layer resulted in insufficient bulk variation and the adhesion to the surface of the object was not easy.
Finally, it is clear from the data of comparative examples 4, 6 and 8 that only the highlight layer was adhered to the target, but the transfer film was difficult to be applied to the market because the PET film had poor ductility and wrinkles were easily generated when the PET film was used as the base material, and the transfer film was not adhered to the second and third transfer regions.
Lamination effect test of transfer film
As shown in fig. 4, the target is a decoration and has a convex portion 2011, an extending platform 2014 and a curved surface 2015, and the convex portion 2011, the extending platform 2014 and the curved surface 2015 are integrally formed; after the transfer film is applied to the decoration, the high gloss layer 110 can be attached to the protrusion 2011, the extension 2014 and the curved surface 2015, so that the whole appearance of the decoration can have a visual effect of specular reflection; although the planar width of the extended platform 2014 is less than 1 mm and the circumferential length thereof can exceed 3 cm, the highlight layer 110 can still be well attached to the extended platform 2013 and the connecting bending part between the extended platform 2014 and the convex part 2011 and the curved surface 2014 without wrinkling, so the invention has excellent attaching effect.
In summary, the present invention provides a technical means different from the conventional method that the mirror reflection effect can be obtained only by electroplating with water, vacuum electroplating, water transfer printing and spraying, the transfer printing film of the present invention is transferred to the target without mirror reflection effect, the surface of the target can be modified by the high gloss layer of the transfer printing film as desired, and the target can be given the visual effect of mirror reflection, and the transfer printing film can give the visual effect of mirror reflection to the target no matter whether the material and the surface of the target are pre-formed with ink or whether a detailed structure is provided, and has a good transfer printing rate, thereby improving the texture, the fineness and the value of the overall appearance of the target.
The above embodiments are merely examples for convenience of description, but the embodiments are not intended to limit the scope of the invention; it is intended that all such alterations, modifications, and other changes which come within the spirit of the invention are desired to be embraced therein without departing from the scope of the appended claims.
