Description

  The present invention relates to a sticker attached to a smoke glass of a vehicle.

  Conventionally, as car exterior decoration stickers, there is a base film provided with a concealing layer, a color layer and a clear layer, and by providing a concealing layer on the base of the color layer, it is not affected by the color of the application site In addition, the color layer can be visually recognized.

  Moreover, as a stained glass-like film for dwelling interiors, there is one in which a color layer is provided on the surface of a transparent base film and the back side of the base film is attached to a window glass. Since this stained glass-like film has no concealing layer, outdoor and indoor light is transmitted through the color layer, and a stained glass-like window glass is obtained.

  By the way, when the above-mentioned automobile exterior decoration sticker is affixed to automobile smoke glass for UV protection, privacy protection, etc., the color layer can be visually recognized by reflected light when viewed from the outside of the vehicle because there is a concealing layer. However, the color layer cannot be visually recognized from the inside of the vehicle due to the shielding layer.

  In addition, when the above-mentioned stained glass film for residential interiors without a cover layer is applied to smoke glass for automobiles, external light is transmitted and the color layer is beautifully colored on the inside of the car. The appearance from the dark becomes dark, and the color development of the color layer cannot be obtained.

  On the other hand, considering the difference in appearance between reflected light and transmitted light, the same image can be transferred, printed, or affixed with a transparent film on both sides of a white translucent film having transmission, reflection and concealment functions. There has been proposed a day / night combined image (for example, Patent Document 1) having a structure in which both images completely overlap outlines.

  In the day / night combined image disclosed in Patent Document 1, reflected light and transmitted light are obtained by setting the color density (density) of an image viewed with transmitted light to twice the color density (density) of an image viewed with reflected light. Both of them are described as being able to see beautiful images. However, even in this day / night combined image, if the image is pasted on the smoke glass for automobiles, the transmittance of transmitted light from the outside of the vehicle is lowered by the smoke glass, so that the image viewed from the inside of the vehicle becomes dark.

  Furthermore, in the double-sided design sticker, for the purpose of improving the visibility through the smoked glass, a support layer, a printed layer applied to at least one surface of the support layer, and an adhesive layer on the printed layer side There is a pressure-sensitive adhesive sticker (for example, Patent Document 2) for attaching a low light transmittance medium in which the pressure-sensitive adhesive layer is provided only around the support layer. In the double-sided pattern type sticker of Patent Document 2, it is described that the visibility through the smoked glass is improved by providing an adhesive layer only around the printed layer and providing a smooth air layer between the smoked glass and the printed layer. Has been.

  However, since the double-sided design sticker of Patent Document 2 is a sticker for reflected light, it is necessary to print the design on both sides of the sticker. In addition, when a double-sided design sticker is attached to the smoke glass of an automobile, the outside cannot be seen from the sticker location, visibility from the inside of the car is reduced, the outside of the car is difficult to understand, and the inside of the car is not bright. And I can't see the pattern on the indoor side.

It is sectional drawing of the sticker which provided the recessed part on the surface, and smoke glass same as the above.

  Hereinafter, embodiments of the sticker of the present invention will be described with reference to the drawings.

  1 to 5 show Embodiment 1 of the present invention. As shown in the figure, a sticker 1 which is a vehicle sticking print sheet is attached to the outer surface of a smoke glass 2 of a vehicle such as an automobile. Examples of the smoked glass 2 include those in which the light transmittance of the glass itself is lowered and those in which a film for automobile window glass is attached to glass, and the light transmittance is lower than that of transparent glass.

  The sticker 1 is formed by superposing a white translucent printing layer 4, a translucent printing layer 5, and a transparent clear printing layer 6 having optical transparency on the surface of a transparent substrate 3 having optical transparency. A transparent adhesive layer 7 having light transmittance is provided on the back surface of the transparent substrate 3. And the white semi-transparent film | membrane 8 is comprised by the said transparent base material 3 and the white semi-transparent printing layer 4 given to the surface of this transparent base material 3. FIG. The translucent printing layer 5 is a colored display portion, and in this example represents a figure imitating a stained glass.

  Semi-transparent means that the degree of transparency is less than that of transparent. Translucent is less light transmissive than transparent and transmits part of light and reflects part of it.

  The transparent substrate 3 is a synthetic resin transparent film made of polyurethane resin, vinyl chloride resin, PET resin (polyethylene terephthalate), or the like. As a printing method for the printing layer, ink jet printing or silk screen printing is used. For printing, synthetic resin ink such as urethane ink and vinyl chloride ink is used. The transparent substrate 3 has a thickness of 50 to 500 μm, which is thicker than the printing layers 4, 5 and 6.

  The white translucent printing layer 4 is formed by applying white printing having a thickness of about 2 to 10 μm on the surface of the transparent substrate 3 and is formed by dot printing by ink jet printing or silk screen printing. In this case, the translucent white translucent print layer 4 is formed by adjusting the ratio of the print area (area where dots are formed) and the non-print area (area where dots are not formed) in dot printing. be able to.

  The white translucent printing layer 4 constitutes a translucent hidden printing layer. In printing using white ink, the translucent white translucent printing layer 4 can be formed by adjusting the thickness of the printing layer without providing a non-printing area.

  The translucent printing layer 5 is printed on the surface of the white translucent film 8 provided with the white translucent printing layer 4 with a thickness of about 2 to 10 μm. And a pattern or a picture is represented by printing using a plurality of colors of ink.

  The clear print layer 6 is formed to a thickness of 10 to 20 μm on the surface of the translucent print layer 5 with a transparent ink. Preferably, the clear print layer 6 is formed by silk screen printing, and is formed thicker than the white translucent print layer 4 and the translucent print layer 5.

  In this case, since the clear printing layer 6 becomes an overcoat layer of the semi-permeable printing layer 5, when the semi-permeable printing layer 5 is formed by inkjet printing or the like, it is more durable than the semi-permeable printing layer 5. The translucent printing layer 5 can be protected by the high silk screen printing clear printing layer 6. The transparent adhesive layer 7 is provided by printing or coating.

  By the way, in this example, in silk screen printing, a silk screen (plate) on which a printed image simulating a stained glass is drawn is produced, and, for example, solvent-drying type or thermosetting ink is printed through the silk screen, Since silk screen printing is performed by single color printing, in order to print different colors, it is necessary to perform multilayer printing using inks of different colors. For this reason, silk screen printing has a problem that it takes time and time for processing.

  In contrast, inkjet printing is a method of printing by spraying ink from an electronically controlled head nozzle, and multicolor printing can be performed at a low cost, but compared to silk screen printing, The inventors have inferior durability, and the inventors propose a new manufacturing method based on these viewpoints.

  An example of the manufacturing method of the sticker 1 according to the present invention will be described focusing on printing. As shown in FIG. 4, the white translucent printing process (S1) which prints the white translucent printing layer 4 on the said transparent base material 3 is performed by inkjet printing. Next, a translucent printing step (S2) for printing the translucent printing layer 5 on the surface of the white translucent printing layer 4 is performed by ink jet printing, and multicolor printing is performed in the translucent printing step (S2). Do. Next, a clear printing step (S3) for printing the clear printing layer 6 on the surface of the semi-transmissive printing layer 5 is performed by silk screen printing. In this case, the white translucent printing layer step (S2) may be carried out by ink jet printing following the white translucent printing step (S1). Specifically, the white translucent printing layer 4 and the translucent printing layer. 5 is provided on the same side surface of the transparent substrate 3, so that the white translucent printing in which the white translucent printing layer 4 and the translucent printing layer 5 are continuously printed by an ink jet printer as shown in FIG. And it can also be set as a translucent printing process (S1 ').

  After printing the translucent print layer 5, a clear print layer step (S3) for printing the clear print layer 6 on the surface of the translucent print layer 5 is performed by silk screen printing.

  In addition, after providing the transparent adhesive layer 7 in the back surface of the transparent base material 3, and providing release paper (not shown) in this transparent adhesive layer 7, the printing process shown in FIG.4 and FIG.5 can be performed, Or you may provide the transparent adhesion layer 7 in the back surface of the transparent base material 3 after the printing process shown in FIG.4 and FIG.5.

  According to said manufacturing method, it can manufacture at low cost compared with silk screen printing by performing the multi-color translucent printing layer 5 by inkjet printing. Moreover, after the white translucent printing layer 4 hardens | cures by inkjet printing, the translucent printing layer 5 can be printed continuously. Furthermore, since the ink-jet print layers 4 and 5 are covered with the clear print layer 6 by silk screen printing or the like, the ink-jet print layers 4 and 5 are protected, and the sticker 1 is excellent in durability.

  And said sticker 1 is affixed on the outer surface of the smoke glass 2 of a motor vehicle. In FIG. 2, the sticker 1 is affixed to the window 31 located on the rear side surface of the automobile. In this case, it is preferable to stick the sticker 1 on the smoked glass 2 of the window 31 that does not open or close. However, if the sticker 1 can be opened and closed, the sticker 1 can be attached to the smoked glass 2 of the window 31A to be opened and closed. The window 31A is provided in a rear door 32 that can be opened and closed in the automobile, and the rear door 32 is a slide door.

  In FIG. 2, reference numeral 21 denotes a rim display unit representing a stained glass rim, and reference numeral 22 denotes a colored glass display unit provided between the rim display units 21. The transparent adhesive layer 7 of the sticker 1 is provided with a release paper (not shown). The release paper is peeled off and the sticker 1 is attached to the outer surface of the smoked glass 2.

  Thus, in the sticking structure of the sticker 1 in which the sticker 1 is attached to the outer surface of the smoked glass 2, the outside light G is reflected from the outside of the vehicle to the white translucent printing layer 4 and the smoked glass 2, and the reflected light H of the outside light G is reflected. , H and the design of the translucent print layer 5 is colored and visually recognized, and the design of the translucent print layer 5 is visually recognized by the transmitted light T of the in-vehicle light N traveling from the inside of the vehicle to the outside of the vehicle. The external light G is transmitted through the white translucent printing layer 4 and the smoked glass 2, and the design of the translucent printing layer 5 is colored by the transmitted light T of the external light G and visually recognized, and the reflected light H of the in-car light N Thus, the design of the semi-transmissive printing layer 5 can be visually recognized. When the outside of the vehicle is brighter than the inside of the vehicle, the pattern of the semi-transmissive printing layer 5 is colored and visually recognized mainly from the reflected light H of the outside light G from the outside of the vehicle, and semi-transmitted mainly by the transmitted light T of the outside light G from the inside of the vehicle. The pattern of the color print layer 5 is colored and visually recognized. Further, if the outside of the vehicle has a predetermined brightness, it is possible to visually recognize what is outside the vehicle through the sticker 1.

  As described above, the sticker 1 to be attached to the smoked glass 2 includes the white translucent printing layer 4 as a light-transmitting concealing layer, thereby making it possible to achieve both color development outside the vehicle and transparency into the vehicle. In this case, the opacity of the white translucent printing layer 4 is preferably 30% or more and 70% or less. The opacity is a value measured according to JIS P 8149.

  When the opacity of the white translucent printing layer 4 exceeds 70%, the visibility of the translucent printing layer 5 from the inside of the vehicle is lowered, and the external visibility is maintained through the smoked glass 2 and the sticker 1. It is because it becomes impossible. Furthermore, when the opacity of the white translucent printing layer 4 is less than 30%, the color developability of the translucent printing layer 5 from the outside of the vehicle by the reflected light H is lowered.

  Thus, in this embodiment, corresponding to claim 1, the sticker 1 is attached to the smoke glass 2 of the vehicle, and includes a translucent printing layer 5, a white translucent film 8, and a transparent adhesive layer 7. The transparent adhesive layer 7, the white translucent film 8 and the semi-transmissive printing layer 5 are directly superimposed in this order from the side of the smoked glass 2. The transmissive printing layer 5 can be seen.

  Thus, in this example, in correspondence with claim 2, the white translucent film 8 is provided with the white translucent printing layer 4 on the surface which is any surface of the transparent substrate 3, A low-cost sticker 1 can be obtained. The white translucent print layer 4 is preferably provided only on one of the front and back surfaces of the transparent substrate 3.

  Thus, in the present embodiment, in correspondence with claim 3, the white translucent printing layer 4 is a dot printing layer for ink jet printing or a dot printing layer for silk screen printing. Sex can be maintained.

  As described above, in this example, the silk screen clear printing layer 6 was provided on the surface opposite to the smoked glass 2 in this example, that is, the surface of the semi-transmissive printing layer 5 in this example. Sex can be secured.

  Hereinafter, as an effect of the embodiment, since the white translucent film 8 is produced by applying the white translucent printing layer 4 to any surface of the transparent substrate 3, the low-cost sticker 1 can be obtained. Moreover, since it is the method of forming the white translucent printing layer 4 using the dot printing by inkjet printing, or the dot printing by silk screen printing, the visibility of the translucent printing layer 5 is maintainable. Moreover, when the white translucent printing layer 4 is a dot printing layer by inkjet printing, it can be manufactured at low cost, and when it is a dot printing layer by silk screen printing, it is excellent in durability. Moreover, since the translucent printing layer 5 is provided only on the surface side of the white translucent film 8, the visibility from the inside of the vehicle through the smoked glass 2 can be maintained.
