Description

  The present invention provides a decorative effect having a changing effect in which the color tone changes or the pattern changes when the viewing angle is changed without using a member such as a lenticular lens or an embossed sheet. The present invention relates to a decorative structure that can be applied to a specific range in a design with good manufacturability.

  Patent documents 1 and patent documents 2 are known as technology applicable to exterior decoration structures, such as a compact container. The “decorative sheet” of Patent Document 1 basically uses a principle similar to that of a lenticular, but an object thereof is to provide a decorative sheet having a novel configuration that exhibits an ornamental effect that is slightly different from that of a conventional lenticular. The transparent embossed sheet has a structure in which a color pattern printing layer is laminated on the back surface, and a number of fine line lenses are formed on the surface of the transparent embossed sheet. When the decorative sheet is observed from above, the color of the color stripes seen through the upper surface of the lens is dominantly observed. Various color patterns can be observed by changing the correspondence between the lens and the color stripe.

  Patent Document 2 discloses a method for producing a patterned molded body and a patterned molded body obtained thereby by using a non-contact type inkjet printer on the back surface of a transparent layer of a lid plate constituting a lid of a compact container. When a fine pattern formed by combining the striped pattern and the second striped pattern is applied, printing with a transparent ink and printing with a colored ink are performed repeatedly, and a colored layer is further formed on the surface where the fine pattern is formed. It is supposed to be. As a result, each line composing the fine pattern is thickened, and depending on the viewing angle, the two parallel lines of the two striped patterns composing the fine pattern appear to float, and the other Since it appears to sink, it is possible to obtain a fine pattern with a special impression as if the entire pattern is actually a flat surface, as if it were uneven.

  Patent Document 1 obtains a decorative effect by showing fine line-shaped color stripes with light entering and exiting a thin line lens on the surface of a transparent embossed sheet. Since the embossed sheet is used, the decorative surface is smooth. Could not get. Further, although fine line-shaped color stripes appear to be raised, it has not been possible to secure high-quality glitter.

  In addition, there is a need for a work process in which a color pattern printing layer to be printed and a special embossed sheet having a lens effect are separately prepared and bonded and laminated together, and it takes time to produce the decorative sheet itself, When this decorative sheet is attached to an article, an additional step is required, and the productivity is not good.

  Japanese Patent Laid-Open No. 2000-098948 cannot reproduce the so-called changing effect (see Japanese Patent Laid-Open No. 2000-098948) that changes depending on the color tone and the angle at which the pattern is viewed, even though it has a visual effect that makes the printed pattern appear three-dimensional.

  The present invention was devised in view of the above-described conventional problems, and the decoration having a changing effect that changes the color tone or the pattern can be seen by changing the viewing angle, such as a lenticular lens or an embossed sheet. An object of the present invention is to provide a decorative structure that can be applied to a specific range with a desired design by an inkjet printer without using a member, with good manufacturability.

  The decorative structure according to the present invention forms, on the surface of a metallic light reflecting layer, two or three fine wires having the same length and different color tones in contact with each other and arranged in parallel to form a strip-like composite color layer In addition, a plurality of the strip-like composite color layers are arranged and printed in parallel so that the metal light reflecting layer is exposed with an interval equal to the width of the strip-like composite color layer. .

  The narrow strip-shaped composite color layer has a width of 0.03 to 1 mm.

  The thin strip-shaped composite color layer has a thickness of 0.005 mm or more.

The plurality of the strip-like composite color layer rows are arranged in parallel in a range of at least 3 mm ² or more and printed by an ink jet printer.

  In the decoration structure according to the present invention, a member such as a lenticular lens or an embossed sheet is used for a decoration having a changing effect that changes color when the viewing angle is changed or a pattern changes. Without any problem, the ink jet printer can be applied to a specific range with a desired design with good manufacturability.

It is explanatory drawing explaining suitable embodiment of the decorating structure concerning this invention. It is a top view of the decorating structure shown in FIG. It is a perspective view which shows a mode that the polka dot pattern was drawn in the row | line | column of a strip shaped composite color layer as an example of the decorating structure concerning this embodiment. FIG. 4 is an enlarged plan view of a Z part in FIG. 3. It is explanatory drawing explaining the various examples of the form of the row | line | column of a strip shaped composite color layer.

  Hereinafter, preferred embodiments of a decorative structure according to the present invention will be described in detail with reference to the accompanying drawings. The decorative structure according to the present embodiment is provided on the surface of the article itself or on the surface of a sheet material having an adhesive bonding surface that adheres to the article surface. As shown in FIGS. 1 and 2, the decoration structure is mainly used. The light reflection layer 1 made of metal and the strip-shaped composite color layer 2 composed of two thin wires 5 having different color tones that are in contact with each other in parallel.

  FIGS. 1A and 1B show a case where the article itself or the sheet material itself is made of metal, and the light reflecting layer 1 is formed by the article itself or the like. FIGS. 1C and 1D show a material in which the article itself or the sheet material itself does not constitute the light reflection layer 1, for example, a synthetic resin material 3, and the metal light reflection layer 1 is formed on the synthetic resin material 3. Is formed. The metal light reflection layer 1 can be formed on the surface of an article or the surface of a sheet material by various known methods such as vacuum deposition or thermal spraying.

  The type of the metal material is not limited, but aluminum or the like is preferable from the viewpoint of reflection performance (brightness), cost, ease of handling, and the like. The thickness of the light reflecting layer 1 is appropriately set in consideration of durability and weather resistance.

  In the case of a sheet material having an adhesion surface, the sheet material is affixed to the article.

  FIGS. 1A and 1C show a first example in which a strip-like composite color layer 2 is formed directly on the surface of a metal light reflection layer 1. In FIGS. 1B and 1D, a light transmissive resin layer 4 is coated on the surface of the light reflective layer 1 for the purpose of protecting the light reflective layer 1. The 2nd example which forms the strip | belt-shaped composite color layer 2 on the surface is shown. Light transmissive means transparent or translucent that allows light to enter the light reflecting layer 1 and also allows reflected light to be emitted from the light reflecting layer 1, and the light transmissive resin layer 4 is colored. It may be.

  1A shows a case where light is transmitted through the thin line 5 constituting the strip-like composite color layer 2, and FIG. 1B shows that light is not transmitted through the thin line 5 constituting the strip-like composite color layer 2. FIG. Shows the case.

In the first example, a plurality of strip-like composite color layers 2 are formed in parallel on the surface of the metallic light reflecting layer 1 by printing. In the second example, a light-transmitting resin layer 4 is coated on the surface of the light-reflecting layer 1 as a primer treatment, and then a plurality of strip-like composite colors are printed on the surface of the light-transmitting resin layer 4 by printing. Layers 2 are formed side by side. As a method for printing the strip-like composite color layer 2, a UV curable ink jet printer that can be easily overprinted and can easily adjust the thickness of the overlaid ink layer is preferably used.

  Each thin strip-like composite color layer 2 has the same length and almost the same thickness (H), and two (P, Q) or three (P, Q, R) fine wires 5 having different color tones are mutually connected. It is comprised by arranging in parallel in the contact state (refer Fig.1 (a) and FIG.5 (c)). The width (K) of each strip-like composite color layer 2 is 0.03 to 1 mm, and is particularly preferably set to 0.05 to 0.5 mm because the changing effect becomes clearer. The individual widths of the two or three fine wires 5 constituting each of the fine band-like composite color layers 2 need not be the same as long as the total width as the fine band-like composite color layer 2 is 0.03 to 1 mm. . The thickness (H) of the strip-shaped composite color layer 2 is 0.005 mm or more, and is particularly preferably set to 0.01 to 0.1 mm. If the thickness is less than 0.005 mm, the changing effect is not exhibited. Even if the thickness is more than 0.1 mm, only a long time is required for printing, and there is almost no change in the changing effect. The individual thicknesses of the thin strip-like composite color layers 2 and the thin wires 5 constituting them do not necessarily have to be uniform. In order to adjust the angle at which the color tone changes or the pattern changes or can be seen, the thickness can be adjusted appropriately by separately preparing a design only for the portion where the thickness is increased and overprinting only that portion.

  The thin strip-like composite color layer 2 has two (P, Q) or three (P, Q, R) fine wires 5 of different color tones on the surface of the metallic light reflecting layer 1 or the light transmissive resin layer 4. They are arranged side by side in a bundle in contact with each other. That is, the thin strip-shaped composite color layer 2 is configured by arranging two or three thin wires 5 (P, Q, R) having the same length in the width direction with their length directions aligned. In order to obtain a changing effect, each thin line 5 (P, Q, R) needs to have a color tone different from each other at each contact portion. Needless to say, the color of the single thin wire 5 may be partially changed in the length direction. Further, with respect to the strip-like composite color layer 2, the strip-like shape may be linear or curved. By printing a plurality of strip-like composite color layers 2 in parallel, various various color stripe patterns are drawn on the surfaces of the metallic light reflecting layer 1 and the light transmissive resin layer 4 (see, for example, FIG. 2). .

  As shown in FIG. 2, the plurality of strip-like composite color layers 2 are approximately the same as the width (K) of each strip-like composite color layer 2 so that the metal light reflecting layer 1 is exposed between the strip-like composite color layers 2. Are printed in parallel at intervals (D). A gap 6 is formed between the strip-like composite color layers 2 by setting the interval (D). When the strip-like composite color layer 2 is viewed from an oblique direction as if the thickness is observed, two or three in contact with each other. Among the thin wires 5, the fine wire 5 closer to the viewpoint appears to be reflected in the metal light reflection layer 1 exposed in the gap 6. The interval (D) is preferably set to 0.03 to 1 mm in relation to the thickness (H) and width of the strip-shaped composite color layer 2 (thin line 5).

By arranging a plurality of the strip-shaped composite color layers 2 in parallel in the same direction, the entire color layer group exhibits a changing effect at the same angle. Conversely, the band-like composite color layers 2 that are not parallel to each other have different angles at which the changing can be visually recognized. Therefore, in order to make the changing effect clearer, it is desirable to arrange the plurality of strip-like composite color layers 2 in the same direction in a certain range or more, and more specifically, in the same direction in a range of 3 mm ² or more. . For example, by printing ten strip-like composite color layers 2 having a length of 3 mm and a width of 0.05 mm in parallel at an interval of 0.05 mm, the changing effect can be visually recognized at the same angle in a range of about 3 mm ^2. A decorative structure can be obtained.

  When light is transmitted through the fine wire 5, the fine wire 5 transmits the light incident thereon toward the metal light reflecting layer 1, and transmits the light reflected by the light reflecting layer 1 to be emitted to the outside. To do. When the thickness of the thin wire 5 is increased, the color tone is emphasized. On the other hand, when light does not pass through the fine line 5, the color of the fine line 5 is visually observed. In any case, the color of the thin line 5 is reflected on the metallic light reflecting layer 1 exposed in the gap 6 between the strip-shaped composite color layer 2 and the color reflected on the light reflecting layer 1 is visually observed. It is caught at.

  Note that a transparent protective coating 10 may be formed on the surface of the metallic light reflecting layer 1 or on the surface of the light-transmitting resin layer 4 so as to cover the strip-like composite color layer 2.

  Next, the effect | action of the decorating structure concerning this embodiment is demonstrated. As shown to Fig.1 (a), if the incident direction of light L1-L4, in other words, the direction visually recognized, is changed variously, the decoration from which a color tone and light luminance change variously can be obtained. That is, for example, when the fine line 5 (Q) is viewed from the L2 or L3 direction, the thickness of the fine line 5 (Q) is reflected in the metallic light reflecting layer 1 in the gap 6 between the strip-shaped composite color layers 2, It can be visually recognized as the width of the thin wire 5 (Q) is widened. On the other hand, since the other thin line 5 (P) arranged in parallel with the reflected thin line 5 (Q) is located behind the thin line 5 (Q), the visible range is narrowed. As a result, when the viewpoint is changed from L1 to L2 or L3, the color tone and the pattern formed by the thin lines 5 (Q) in the plurality of thin strip-like composite color layers 2 can be visually recognized more clearly. The color tone and pattern composed of P) are hardly visible.

  As described above, the color tone, thickness (H), width (W), width (K) and interval (D) of the strip-shaped composite color layer 2 are variously set according to the required design properties. If you change the viewing angle, you can get a special decoration that looks like the color changes or the pattern changes.

  As an example of the decorative structure, FIG. 4 in which the Z portion in FIG. 3 and FIG. 3 is enlarged shows a case where a polka dot pattern is drawn with color stripes.

  In FIG. 4, the strip-shaped composite color layer 2 in which two thin wires 5 (P, Q) having different color tones are arranged in parallel with each other is arranged on the surface of the rectangular metal light reflection layer 1 with a gap 6 therebetween. A plurality of parallel strips are arranged in parallel to form rows 7 and 8 of strip-like composite color layers. The strips of the composite color layers are arranged in a direction perpendicular to the row 7 of the strips of the composite color layers arranged in parallel from the upper left to the lower right over the whole of the rectangle so as to form a polka dot pattern in the inside. And a row 8 of strip-like composite color layers arranged in a circular range.

  When the decoration of FIG. 4 is viewed from the front, the entire color tone is visually recognized as a color tone that is a mixture of different color tones of the thin lines 5 (P) and (Q), and the pattern is hardly visible. When viewed from the direction A in the figure, the color of the thin line 5 (P) constituting the row 8 of the strip-shaped composite color layer stands out, and the color of the thin line 5 (Q) appears light. On the other hand, the color tone of the row 7 of the strip-like composite color layer is almost the same as when viewed from the front. When viewed from the direction B, on the contrary, the color of the thin line 5 (Q) constituting the column 8 of the strip-shaped composite color layer stands out, and the color of the thin line 5 (P) appears light. Similarly, when viewed from the direction C, the color of the thin line 5 (P) constituting the column 7 of the strip-shaped composite color layer stands out, and the color of the thin line 5 (Q) appears to be faint. Since such a change occurs, the decorative structure in FIG. 4 has a feature that a polka dot pattern appears to rise or disappear in a rectangle when viewed from different angles.

  Further, the color tone of the thin lines 5 (P) and (Q) constituting the row 7 of the strip-like composite color layer and the color tone of the thin lines 5 (P) and (Q) constituting the row 8 of the strip-like composite color layer are respectively If they are different, you can see the polka dots when viewed from the front, but the color will change when the angle is changed.

  In the decorative structure according to the present embodiment described above, two or three thin wires 5 having the same length and different color tone are brought into contact with each other in parallel on the surface of the metal light reflection layer 1. Since the strip-shaped composite color layer 2 formed side by side is arranged and printed in parallel so that the metal light reflection layer 1 is exposed at an interval equivalent to the width of the strip-shaped composite color layer 2, By changing the incident direction or viewing angle, it is easy to decorate with a desired design with an inkjet printer without using an embossed sheet or other material, so that the color tone or the pattern can be changed. Can get to.

  Since a member such as an embossed sheet having a lens effect is not used as in the background art, a smooth decorative surface can be obtained. In addition, since a plurality of strip-like composite color layers 2 are formed on the surface of the metallic light reflecting layer 1 at intervals, the light reflecting layer 1 ensures a decorative effect having a glittering effect that gives a sense of quality. be able to.

  The decorative structure can be easily configured by simply printing the strip-like composite color layer 2 on the surface of the light reflecting layer 1 made of metal, and the printed color pattern printing layer and the embossed sheet as in the background art Are separately prepared, and the work process of adhering to each other and laminating are unnecessary, and high production efficiency can be secured for the decorative structure itself.

  In addition, regarding the application of the decorative structure according to the present embodiment to the article, when the article or the sheet material itself is made of metal, and even if the article or the like is a synthetic resin material, the metal light reflecting layer 1 is used. By forming this, it is possible to obtain a decorative structure simply by directly printing the strip-like composite color layer 2 on the article, and attach the decorative sheet to the article as in the background art that requires an embossed sheet. Unlike those that require additional steps in some cases, high productivity can be ensured.

  The strip-like composite color layer 2 can be printed by various printing methods. However, by printing with a UV curable ink jet printer, a decorative structure with high accuracy and high production efficiency can be obtained.

  FIG. 5 shows various examples of the form of the strip-like composite color layer 2. FIG. 5A shows a case where two adjacent strip-like composite color layers 2 are combined with thin lines 5 of two different colors (P, Q and R, S). FIG. 5B shows a case where the interval (D) between the strip-like composite color layers 2 is appropriately changed (D1> D2).

  FIG. 5C shows that the number of colors of the thin line 5 of each strip-like composite color layer 2 is changed to two colors (P, Q) or three colors (P, Q, R), or the width ( W) is changed (W1> W2). FIG. 5D shows a case where the thickness (H) of each thin wire 5 constituting the thin strip-like composite color layer 2 is changed (H1> H2> H3).

  In any of these examples, it is needless to say that the same operational effects as those of the above embodiment can be obtained.
