Description

  The present invention relates to a method of forming a figure having a three-dimensional display effect using a marking sheet and a figure three-dimensional display using the marking sheet. More specifically, in the present invention, a marking sheet graphic is attached to one surface of a transparent plate, and a marking sheet graphic having a shape slightly smaller than this is attached to the other surface, or a transparent plate By creating a matte figure on one surface and sticking a marking sheet figure that is slightly smaller than this on the other surface, the observer can feel the figure three-dimensionally on the other side. The present invention relates to a method of forming a figure having an effect (method of forming a pseudo three-dimensional figure) and a figure three-dimensional display.

  Conventionally, marking sheets are cut into letters and figures and pasted on glass, plastic, metal, wood, and cement surfaces to decorate show windows, create signboards, and display company names on entrance doors. In addition, display or decoration of wall surfaces indoors and outdoors, decoration of furniture, etc. are widely performed. The marking sheet is a thin sheet that is usually colored with a dye or a pigment and that is provided with an adhesive layer on one side of a base sheet made of a thin resin layer having a thickness of about 30 to 500 μm. Therefore, even if this marking sheet is simply affixed to a flat substrate such as glass, it does not give a three-dimensional display or decoration, and the marking sheet forms a figure or pattern that gives a three-dimensional effect. However, this has not been done in particular.

  On the other hand, attempts to perform a three-dimensional display using a sheet-like material have been made widely. Examples of such a method include forming a sheet with a concavo-convex pattern by embossing, providing a three-dimensional effect with this concavo-convex pattern, filling the intaglio surface of a rotating drum with a synthetic resin, and then solidifying and peeling off. There are known methods for imparting a three-dimensional effect by using a sheet with a convex shape molded on the surface, a method for imparting a three-dimensional effect by using this convex shape, and a method for imparting a three-dimensional effect by using a sheet of synthetic resin formed thickly using a silk screen method. ing. All of these methods provide a three-dimensional effect by actually forming a three-dimensional part on the sheet itself. By these methods, a three-dimensional effect is imparted to the sheet and the decorativeness is enhanced. However, additional steps are required to produce these sheets having a three-dimensional effect, both of which are expensive. In addition, for example, embossed sheets have a problem of lack of profoundness although they have a three-dimensional effect, and in order to change the three-dimensional pattern, it is necessary to create a new roll for shaping, etc. It is difficult to change the pattern. On the other hand, a sheet formed with a convex shape and a thick sheet by silk screen printing have a heavy feeling, but the manufacturing process is complicated, and there is a problem in dealing with changes in the uneven pattern. Moreover, the three-dimensional effect of these sheets is only microscopic.

  As a method other than the above, a decorative sheet having a three-dimensional (3D) feeling while being flat is manufactured by superimposing a lenticular lens on a stereo printed sheet. A sheet formed by stereo printing has a stereoscopic effect using the action of parallax stereogram by a lenticular lens. However, since a lenticular lens has to be used, there is a problem from the viewpoint of decorativeness. Furthermore, the conventional one is not satisfactory in terms of stereoscopic effect.

Further, it has been proposed to use a moire pattern to feel a virtual depth, or to form a decorative pattern having a three-dimensional effect by combining a lenticular sheet and a moire pattern (see, for example, Patent Documents 1 and 2). ). However, in these methods, it is necessary to newly create a moire pattern, which is complicated and cannot cope with any decoration pattern.

  The present invention is a method for forming a figure having a three-dimensional effect that is free from the above-mentioned problems, that is, without using complicated processes and without using special materials and devices (pseudo three-dimensional figure). Forming method).

  That is, the present invention relates to a first figure made of a marking sheet, and the first inside out, which is different in color from the first figure and has an outer edge within a certain distance from the outer edge of the figure turned upside down. Forming a second figure consisting of a marking sheet that is slightly smaller than the figure, placing the first figure on one side of the opposing surface of the transparent plate, and the other side of the transparent plate and the transparent A method for forming a figure having a three-dimensional display effect, characterized in that the second figure is pasted within an outer edge of a vertical projection figure of the first figure with respect to a plate surface.

  The present invention is also the above-described method for forming a figure having a three-dimensional display effect, wherein the transparent plate is made of glass or plastic and has a thickness of 2 to 10 mm.

  Further, the present invention is characterized in that the first graphic is formed by a colorless translucent marking sheet having fine irregularities on the surface, and the second graphic is formed by a colored marking sheet. This is a method of forming a figure having any one of the above three-dimensional display effects.

  In the present invention, the first graphic is formed by a colored marking sheet, and the second graphic is formed by a colored marking sheet having a color different from that of the marking sheet constituting the first graphic. A method of forming a figure having any one of the three-dimensional display effects described above.

  According to the present invention, the second graphic has an outer edge at a fixed inner distance from the outer edge of the inverted graphic of the first graphic, and the outer edge of the inverted graphic of the first graphic and the second graphic In the method of forming a figure having any one of the above three-dimensional display effects, the certain distance from the outer edge is 1 to 10 mm.

  In the present invention, a first figure made of a marking sheet is attached to one surface of a transparent plate, and the vertical projection figure of the first figure is the other surface of the transparent plate and the transparent plate surface. In the outer edge of the first figure, the color is different from that of the first figure, and the figure is slightly smaller than the inverted figure of the first figure having an outer edge within a certain distance from the outer edge of the figure that is the first figure turned upside down. It is a figure three-dimensional display body characterized by sticking the 2nd figure which consists of a marking sheet.

  In addition, the present invention forms a first graphic matted by sandblasting on one surface of a transparent plate, and is perpendicular to the other surface of the transparent plate and to the transparent plate surface. In the outer edge of the projected figure, a second figure made of a colored marking sheet, which is a figure slightly smaller than the first inverted figure, having an outer edge within a certain distance from the outer edge of the figure that is the first figure turned inside out, is pasted. This is a method for forming a figure having a three-dimensional effect characterized by wearing.

  The present invention also has a matte first figure formed by sandblasting on one surface of the transparent plate, and the first figure is formed on the other surface of the transparent substrate and with respect to the transparent plate surface. A second graphic composed of a colored marking sheet, which is a graphic slightly smaller than the first inverted graphic, having an outer edge within a certain distance from the outer edge of the graphic inverted from the first graphic within the outer edge of the vertical projection graphic. Is a figure three-dimensional display body characterized by being attached.

  In this specification, unless otherwise specified, “graphics” is used to mean figures of any shape including figures such as numerals, letters including alphabets, hiragana, katakana, and kanji. It is done. Further, in the present invention, “the colors are different” means that one of hue, saturation, and lightness is different from each other, and one is matt, the other is not matt, and one is Including those which are transparent and the other is opaque.

Effects of the invention

  In the present invention, the first graphic formed by the marking sheet is attached to one surface (for example, the back surface) of the transparent plate having a thickness of a certain level or more, and the other surface (for example, the opposite surface) (for example, the back surface) A second figure formed by a marking sheet that is slightly smaller than the first figure and formed from a marking sheet different from the color of the first figure is stuck on the surface) so as not to protrude from the first figure. However, when the transparent plate to which the graphic is attached in this way is viewed from the second graphic side, the two marking sheet graphics that are attached in an overlapping manner are observed with a stereoscopic effect. Although the present invention is not limited to this because of this effect, the first and second figures attached to the transparent plate have similar shapes except that they are different in size. In addition, since the large graphic similar to the thickness of the transparent plate is arranged at a distance behind the similar small graphic, the two eyes are attached even though two flat graphics are attached. An illusion of the figures in one piece, it is thought that a small figure attached to the front appears to rise from a large figure attached to the back. Such an effect is produced more or less if the color of the first graphic is different from the color of the second graphic, that is, any one of hue, saturation, and brightness is different. This effect is also observed when the first graphic attached to the back of the transparent plate is a matte colorless figure, and when the hue of the second graphic is black, the graphic is The effect that looks three-dimensional becomes extremely large. Further, even if the matte figure is not the marking sheet figure, that is, a figure formed by matting the surface of the transparent plate by sandblasting or the like, the same effect can be obtained.

BEST MODE FOR CARRYING OUT THE INVENTION

  The marking sheet having an adhesive layer used in the method for forming a pseudo three-dimensional pattern of the present invention includes, for example, NOCS, cutting sheet, fograss (all commercially available from Nakagawa Chemical Co., Ltd .; “NOCS”, “cutting sheet”, “fograss”). Many types of products are already on the market under the trade name or other trade names, and as mentioned above, conventionally, glass such as signs, show windows, doors, outer walls of buildings, inner walls, enclosures of construction sites It is widely used for decoration, display, protection, and marking of various other articles. Commercially available NOCS has a 1000 mm or 1010 mm width and 20 m roll, and the cutting sheet is usually specified as a L dimension of 920 mm width and 20 m roll, and an R dimension of 450 mm width and 12 m roll. In the present invention, since it is difficult to obtain a stereoscopic effect when the first figure located below is seen through the second figure, the marking sheet used for forming the second figure is preferably opaque. . In addition, the marking sheet that forms the first graphic that is particularly larger than the one can see the graphic from the adhesive layer side, and therefore the adhesive layer needs to be transparent. Before explaining the method of forming a pseudo three-dimensional pattern using the marking sheet of the present invention, a conventional method known in the art or a known method of pasting a marking sheet figure on a substrate using this marking sheet is shown in FIG. A description will be given with reference to FIG.

  FIG. 1 shows a partial cross-sectional view of a marking sheet. The film thickness and the like are expressed as appropriate thicknesses for convenience of explanation, and the layers are not necessarily described in an accurate ratio. The same applies to the other figures. In FIG. 1, the marking sheet 1 is usually composed of a base sheet 2 and an adhesive layer 3, and a release paper 4 is attached to the surface of the adhesive layer for protecting the adhesive layer. The base sheet 2 is composed of a plastic sheet having a thickness of, for example, about 30 to 500 μm, more generally about 50 to 200 μm, and usually colored by containing a dye or a pigment. The plastic material constituting the base sheet 2 includes polyvinyl chloride resin, polyester resin such as polyethylene terephthalate, polyethylene resin, polypropylene resin, acrylic resin, polycarbonate resin, polyurethane resin, silicone resin, Typical examples include singles and blends of synthetic resins such as fluororesins. The layer structure of the base sheet 3 is composed of a single layer or a composite layer such as a laminate. Further, the base sheet is known to be transparent or opaque, colored as described above, or uncolored, a smooth surface, or matte. Furthermore, the base sheet 2 is printed on the surface if necessary.

  On the other hand, as the material constituting the pressure-sensitive adhesive layer 3, acrylic, vinyl chloride / vinyl acetate, rubber-based pressure-sensitive adhesives and the like are representative, and the thickness is not particularly limited. The thing of the range of 200 micrometers is generally used. Pressure-sensitive and heat-sensitive adhesives are known. The adhesive layer of the marking sheet may be transparent or opaque, but since the first figure is observed from the adhesive layer side, at least the adhesive layer of the marking sheet for forming the first figure Must be transparent.

  Moreover, as for the release paper 4, it is common that the release layer 4b is formed in the adhesion layer side of the base paper 4a, for example by apply | coating a silicone release agent. Further, on the surface opposite to the adhesive layer 3 of the base paper 4a, the surface of the base paper is smoothed, and the releasability of the marking sheet from the base sheet 2 when the marking sheet is rolled up is good. For the purpose of, for example, a resin layer 4c made of polyethylene or the like is provided as necessary.

  In order to attach a figure of a desired shape to the adherend 9 using these marking sheets, first, as shown in FIG. 2A, cutting of the desired shape is performed on the marking sheet. As a cutting method at this time, a computer cutting method using a cutting machine (plotter) from the base sheet 2 of the marking sheet 1 or a manual cutting method using a cutting knife is employed. In this cutting process, a cutting line 5 of a desired shape of characters, figures and the like is put on the marking sheet. At this time, the cutting is performed to a depth halfway through the release paper 4 (half cut). The In the case of computer cutting, information such as characters and figures is formed by CAD / COM and the like, and the marking sheet is cut by transmitting this information to a cutting machine.

  Next, as shown in FIG. 2 (b), the base sheet 2 of the half-cut marking sheet and the scraped portions (unnecessary portions) 2 b and 3 b of the adhesive layer 3 are removed (scrap lift), and the release paper 4 is placed on the release paper 4. The base sheet 2a and the adhesive layer part 3a of the pattern part which makes the figure of desired shape remain. Thereafter, as shown in FIG. 2 (c), an application sheet (transfer sheet) 6 carrying an adhesive layer 8 having an appropriate adhesive force is pressed against one side of the substrate 7, and the remaining base having the desired shape is pressed. The adhesive layer 8 of the application sheet is bonded to the surface of the sheet 2a. As the base material 7 of the application sheet 6, stretched polypropylene, impregnated paper, polyester such as polyethylene terephthalate, or the like is used. Next, as shown in FIG. 2 (d), the application sheet 6 is peeled off. As a result, the marking sheet 2 a and the adhesive layer 3 a having a desired shape are peeled from the release paper 4 together with the application sheet.

  If necessary, these steps are repeated for marking sheets of other colors, and a plurality of color figures are arranged in a desired arrangement on the same application sheet 6. As shown in FIG. 2 (e), the application sheet 6 carrying one or more figures made of the marking sheet thus obtained is displayed or decorated as desired. It aligns to a position and the adhesion layer 3a of a marking sheet is pressed and adhered to the adherend 9. Thereby, the marking sheet symbol portions 2 a and 3 a having a figure shape carried on the application sheet 6 are stuck on the adherend 9. Thereafter, as shown in FIG. 2 (f), the application sheet 6 is peeled off from the marking sheet graphic surface of the design portion, whereby display or decoration made up of characters, graphics, etc. is performed on the adherend.

As above-mentioned, in this invention, the marking sheet figure from which a magnitude | size and a color differ on the front and back of a transparent plate. The transparent plate may be any transparent plate such as a plastic plate such as acrylic or a glass plate. In the present invention, since the figure is stereoscopically viewed as a composite image of the first and second marking sheet figures attached to the front and back of the transparent plate, the first figure (one size larger figure) is transparent. It is desirable to see the shape and color clearly through the board. For this reason, the transparent plate is preferably colorless and transparent. Moreover, even if the thickness of the transparent plate is too thick or too thin, it is difficult to obtain a stereoscopic effect. Further, in the case where the first graphic and the second graphic are attached to the front and back of the transparent plate, the stereoscopic view observes the second graphic through the transparent plate from the front or oblique direction on the second graphic side. In some cases, when observing from the oblique direction of the first graphic, if the second graphic protrudes even partially from the outline of the first graphic, the stereoscopic effect is reduced. Or it becomes difficult to obtain. Also, the thickness of the transparent plate is different because the thickness of the transparent plate on which the figure can be observed with a three-dimensional effect also varies depending on the size of the figure formed on the front and back of the transparent plate, the difference between the size of the first figure and the second figure, etc. In consideration of the size of the first graphic, the difference between the size of the first graphic and the size of the second graphic, the degree of swell required for the three-dimensional graphic, etc. Considering whether or not the pattern can be stereoscopically viewed within the angle range, the thickness may be an appropriate thickness. However, it is usually 2 to 15 mm, more preferably about 3 to 10 mm. For example, when the design is composed of a plurality of figures and the overall size is large, it is generally preferable to make the thickness of the transparent plate thin in order to obtain the overall stereoscopic effect. Furthermore, it is preferable that the front and back surfaces of the transparent plate to which the first and second figures are attached are parallel planes.

  In addition, the first graphic and the second graphic can be stereoscopically viewed if the second graphic is slightly smaller than the first graphic and the hue, saturation, or brightness is different from each other. In general, the larger the hue difference, saturation difference, and brightness difference between the first graphic and the second graphic, the greater the effect. For example, an example in which the first figure is formed by a white marking sheet and the second figure is formed by a black marking sheet as a lightness difference. In this case, an excellent stereoscopic effect can be obtained when viewed from an oblique direction. Further, when the first graphic is formed of a matte colorless marking sheet, for example, fograss, and the second graphic is formed of a white marking sheet, a colored marking sheet or a black marking sheet, An excellent solid figure can be observed when an excellent solid figure is observed from any of the oblique directions and the second figure is black. Further, even when the first and second graphics are, for example, red and green or yellow and blue, or a combination of colors close to or complementary to each other, they can be similarly observed as a three-dimensional graphic. Of course, the figure can be observed three-dimensionally by other color combinations.

  The shape of the figure that can be stereoscopically viewed is not particularly limited, but it is generally preferable that the figure is a line figure such as a character figure. Also, the size of the figure may be arbitrary, but since it is difficult to obtain a stereoscopic effect in either case of being too large or too small, the size of one figure is related to the first figure. Is preferably about 0.5 to 30 cm in length and about 0.5 to 30 cm in width. Furthermore, the distance between the outer edge (contour line) of the first graphic and the outer edge (contour line) of the second graphic that is slightly smaller than the first graphic also depends on the size of the graphic, the thickness of the transparent plate, etc. Although it is different, its value is not particularly limited, but generally it is preferably about 0.1 to 1 times the thickness of the transparent plate. Further, specific numerical values may be about 1 to 10 mm, more preferably about 3 to 5 mm. The width between the contour of the first graphic and the contour of the second graphic is preferably the same width over the outer periphery of the graphic, but it is not necessarily required to be exactly the same width. In the present invention, the two marking sheet figures different in hue, saturation or brightness, which are pasted on the front and back surfaces of the transparent plate, are perceived as a single body through the transparent plate as if the eyes were integrated. Therefore, if the marking sheet is printed on the surface, attention may be paid to this printed pattern, and as a result, there may be cases where stereoscopic viewing is not performed. The marking sheet to be used is preferably one having no printed pattern on its surface.

  The method for forming a three-dimensional pattern according to the present invention will be described more specifically with reference to FIGS. FIG. 3 is a plan view of the transparent plate 10 in which the first character graphic 11a and the second character graphic 12a of “NC” having different sizes as viewed from the second graphic 12a side are attached to the front and back surfaces. . 4 and 5 are cross-sectional views taken along lines AA and BB in FIG. 3, respectively. In the example of FIG. 3, an acrylic plate having a thickness of 5 mm is used as the transparent plate 10, and the first figure 11 a is a translucent fograss C-16 (inc. The second figure 12a is formed by using a cutting sheet 791 which is a black marking sheet. The size of the figure is 60 mm in length and breadth for both N and C for the first character figure. The first character is cut as a graphic in which the NC character is turned over so that the first character becomes an NC character graphic when viewed from the back side. On the other hand, the second graphic is an NC character graphic having a contour line on the inner side 3 mm along the contour line of the graphic (NC character graphic) obtained by turning over the first graphic. As shown in FIGS. 4 and 5, the first graphic 11 a and the second graphic 12 a are formed on the front and back surfaces of the acrylic plate 10 having a parallel plane, and the outer edge (contour line) of the second graphic 12 a is acrylic. In the vertical direction of the first graphic 11a with respect to the plate surface, each is attached so as to be located 3 mm inside the vertical outer edge of the first graphic. When the NC symbol in FIG. 3 is viewed from the front direction and the diagonal direction on the second graphic side, each character of the second NC symbol is observed as being greatly raised on the first graphic.

  The first and second character figures 11 a and 12 a were manufactured as follows and adhered to the acrylic plate 10. That is, since the first character figure is seen from the adhesive layer side after being attached to the acrylic plate 10, information as a shape in which the NC is turned upside down is formed by CAD / COM or the like. This information was transmitted to the cutting machine, and the fog glass C-16 was cut (half cut) by the cutting machine, and the cutting part was cut off from the cutting sheet. A cutting line 11c on the cutting sheet 11 cut out at this time is shown in FIG. On the other hand, the second character graphic “NC” is formed by CAD com or the like to form a character graphic having a contour line 3 mm inside along the contour line of the NC character graphic with the first graphic turned upside down. The character information was created, and this information was transmitted to the cutting machine, whereby the cutting sheet 791 was cut (half cut), and the cutting portion was cut out from the cutting sheet. A cutting line 12c on the cutting sheet 12 cut out at this time is shown in FIG. The order of forming the information of the first and second graphics and the order of performing the cutting of the first and second graphics may be any order.

  The half-cut first graphic 11a and second graphic 12a were each attached to a predetermined position on the acrylic plate by the same method as shown in FIG. In other words, the unnecessary portions 11b and 12b of the marking sheet that has been half-cut are raised, the graphics remaining on the transfer paper are transferred to 11a and 12a, respectively, and the transferred graphics are transferred to the predetermined acrylic sheet 10. The application sheet was peeled off from the figure, and the pattern consisting of the first figure and the NC figure consisting of the second figure were stuck and formed on the acrylic plate 10. Either the first figure or the second figure may be attached to the acrylic board first, but first the first figure is attached to the acrylic board, and then the position of the first figure is acrylic. It is preferable to stick a second graphic, which is slightly smaller than the first graphic, at a predetermined position while checking through the plate because it is easy to perform alignment.

  In the above example, the graphic is an alphabetic character and the design is a combination of alphabetic characters. However, the graphic is not limited to an alphabetic character, but a kanji, hiragana, numeral, other arbitrary graphic, and any of these The combination may be as described above. Also, the size of the characters and the width of the first graphic outline and the second graphic outline are not limited to 3 mm, and may be any width. Further, the types and colors of the marking sheets are not limited to the combinations exemplified above.

  In the above example, the matte figure which is the first figure is formed by the marking sheet (fog glass), but the same effect can be obtained by forming the first matte figure directly on the surface of the transparent plate by the sandblast method. Is done.

  As described above, according to the present invention, it is possible to obtain a display with a large three-dimensional effect or an arbitrary shape that could not be obtained conventionally by a simple operation of sticking a known marking sheet to a transparent plate. A decorative figure can be formed. In addition, even if a display or decorative graphic is once provided on the transparent plate, if both the front and back surfaces are marked with a marking sheet graphic, the marking sheet attached on the transparent plate is peeled off and the same operation is performed again. Another design having a three-dimensional effect can be easily formed on the same transparent plate, and effects such as reuse of the transparent plate and change of the design at an arbitrary time are also exhibited.
