Description

  The present invention relates to fashion products such as clothes, hats, shoes, bags, and the like on which hidden designs are formed.

The retroreflective display has been used for traffic signs, etc., because it has excellent visibility to the headlights of motor vehicles, etc., but recently it has become visible for the purpose of fashion effects. Clothes and the like on which a retroreflective design pattern is described have been proposed.
For example, the following Patent Document 1 describes that a flexible and thin retroreflective film is installed in a free form at a free position on clothes. Patent Document 2 describes that a retroreflective ink is attached to a mesh ground as clothing by printing or the like. According to these, the comfort of clothes with retroreflective properties is improved. Patent Document 3 describes that a color retroreflective ink product similar to a cloth is fixed to the cloth surface. According to this, the color and decoration of clothes can be maintained day and night.

By the way, in various shows and events, for the purpose of surprise the audience, there is a case where a strange directing effect is given to the clothes of the person appearing on the stage. However, simply writing a retroreflective design on the clothing as described above has required the lighting to be devised so that the light source can be directly applied to that portion, and so much production effect cannot be obtained.
The present invention has been devised as a result of such considerations, and by forming a retroreflective design design as a hidden design on the same part of a fashion product such as clothing, along with a normal design design. At first glance, the aim is to provide fashion products that can produce effects like magic tricks.

  The present invention is a fashion product in which a desired design pattern is formed in a visually recognizable part and is further formed with another hidden design superimposed on the design design, wherein the hidden design emits light from a light source. It is characterized in that when it is directly radiated, it is reflected in the direction of the light source so as to appear instead of the design design.

In the present invention, an effect such as a magic effect that a design design and a hidden design are displayed interchangeably in the same part of a fashion product depending on illumination conditions is obtained.
That is, under lighting conditions in which the light source does not directly illuminate the design design, there is almost no reflection of light on the hidden design, and light is reflected by the design design, so only the design design appears, while the light source directly illuminates the design design. Under the lighting conditions, the hidden design appears in place of the design design because the hidden design reflects the light better than the design design due to the retroreflection effect.

It is a top view which shows the basic composition of the fashion product made into an example of embodiment of this invention. (A) is a plan view showing how the design design looks when the present embodiment is viewed under normal light, and (b) is the appearance of the hidden design when the present embodiment is viewed under direct light.

  The fashion products to be implemented by the present invention are clothes, hats, shoes, bags, and the like worn by the user and may be of any type, but the following is a description of an embodiment in which clothes (T-shirts) are implemented. .

  FIG. 1 is a plan view showing a basic configuration of a fashion product as an example of an embodiment of the present invention. The fashion product 1 is formed by superimposing at least a part of the design design 10 and the hidden design 11 on a part that can be seen by others when worn, in this example, the same part on the front body. The part may be made of fiber as a base material, synthetic resin or the like as a base material, or may be formed of a metal plate or the like.

  The design design 10 is a character, design, or picture that can be identified by a person. As an example of the design pattern 10, a combination of “♂” and “♀” marks is shown. There is no particular restriction on the design and size of the design design 10. The design design 10 is not particularly limited as long as the design material 10 is formed of a dye, pigment, or the like exhibiting irregular reflectivity on the base material of the part. The design design 10 may be color or monotone.

  The fashion product 1 is further formed with another hidden design 11 superimposed on the design design 10. The hidden design 11 is also a character, design, or picture that can be identified by a person. As an example of the hidden design 11, the characters “LOVE for YOU” are written. Although there is no particular limitation on the design and size of the hidden design 11, it is desirable to use a monotone design.

The hidden design 11 is formed of a transparent paint or the like that exhibits retroreflection at the site where the design design 10 is formed. For example, the hidden design 11 can be formed by fixing a large number of fine particles exhibiting a retroreflective action on the part of the fashion product 1.
If the hidden design 11 is formed by such a method, under normal illumination in which light is applied to the part from the ceiling or the like, the fine particles exhibiting a retroreflective action hardly reflect light in the horizontal direction where the person is present, The design design 10 in a place where there are no fine particles diffuses light in all directions including the horizontal direction where a person is present. On the other hand, under illumination that directly shines light directly on the part, fine particles exhibiting retroreflective action reflect light intensively in the direction toward the light source (retroreflection), and the reflected light contains fine particles. It is much more powerful than the light irregularly reflected by the design pattern 10 in the place where it is not.
Therefore, when the fashion product 1 is viewed under normal light (illumination, sunlight), only the design pattern 10 is visible in the part, but when the fashion product 1 is viewed from the vicinity of a direct light source (such as a strobe). In this case, a unique effect that only the hidden design 11 can be seen in place of the design design 10 occurs. That is, it is possible to obtain an effect such as a magic effect that the design design 10 and the hidden design 11 are interchanged in the same part of the fashion product 1 depending on the illumination conditions. Further, when the fashion product 1 is viewed with the naked eye, the design design 10 is visible, but when the photo is taken with a digital camera with a strobe or the like, the hidden design 11 is also photographed.

  FIG. 2A is a plan view showing how the design design looks when the present embodiment is viewed under normal light, and FIG. 2B is a view when the present embodiment is viewed in the vicinity of a direct light source. It is a top view which shows how to show the hidden design.

  When the fashion product 1 is viewed with ordinary light, the light source is located away from the viewer of the fashion product 1, so that irregularly reflected light from the design pattern 10 is directed toward the viewer, but the hidden design 11 The retroreflected light from is not suitable for the viewer. As a result, the hidden design 11 is hidden as shown in FIG. 2A, and only the design design 10 is normally visible.

  On the other hand, when the fashion product 1 is viewed in the vicinity of a direct light source, for example, when the fashion product 1 is photographed with a stroboscope, the light source is in the vicinity of the person (camera lens) viewing the fashion product 1, so that the design design 10 Both the diffusely reflected light from the light and the retroreflected light from the hidden design will go to the viewer. However, the former has low luminance because of weak light, and the latter has high luminance because of strong light. As a result, as shown in FIG. 2B, the design design 10 becomes a dark background and is almost invisible, and the hidden design 11 becomes bright and stands out.

  Next, some examples of a design method and a hidden design forming method in this embodiment will be described.

  As a first method, it is possible to fix a design sheet in which a design design and a hidden design are formed in advance on a portion (plain) of a fashion product to be used as a base (hereinafter referred to as a base product).

  3A is a plan view of an example of the base product, FIG. 3B is a plan view of a design sheet fixed to the base product, and FIG. 3C is a partial view of the design sheet. It is a longitudinal cross-sectional view. FIG. 3C is obtained when a rectangular portion r indicated by a dotted line at the center of FIG. 3B is cut in the horizontal direction.

  The base product 1A is plain. The design sheet 2 has a two-layer structure made of a transparent resin or the like. That is, the design sheet 2 is composed of a first layer 2a in which the design design 10 is formed by a dye or pigment exhibiting irregular reflection properties, and a second layer 2b in which the hidden design 11 is formed by a large number of fine particles 12 exhibiting retroreflection properties. The adhesive 2c is applied to the back side of the first layer 2a. As the adhesive 2c, an adhesive suitable for the type of the base material may be selected. An adhesive capable of obtaining tackiness by pressing with an iron or the like may be used. By fixing such a design sheet 2 to the base product 1A, a fashion product having the design design 10 and the hidden design 11 is obtained.

  As a second method, it is possible to fix the design sheet 2 on which the hidden design is formed in advance in the portion of the base product 1A on which the design design is formed in advance.

  FIG. 4A is a plan view of another example of such a base product, FIG. 4B is a plan view of a design sheet fixed to the base product, and FIG. 4B is the design sheet. It is a partial longitudinal cross-sectional view. FIG. 4C is obtained when a rectangular portion r indicated by a dotted line at the center of FIG. 4B is cut in the lateral direction (cut with the design sheet fixed to the base product).

  A design design 10 is formed in advance on the part of the base product 1A with a dye or pigment exhibiting irregular reflection. In this case, an existing product having the design design 10 may be employed as it is. Design sheet 2 A sheet made of transparent resin or the like, and a hidden design 11 is formed by a large number of fine particles 12 exhibiting retroreflective properties, and an adhesive 2c is applied to the back surface thereof. By fixing such a design sheet 2 to the base product 1A, a fashion product having the design design 10 and the hidden design 11 is obtained.

  A thermal transfer sheet may be used as the sheet material used in the first and second methods.

  As a third method, a hidden design may be printed with a paint exhibiting retroreflectivity on the portion of the base product on which the design design is formed in advance. Specifically, a concealed design is printed with an adhesive on the portion of the base product on which the design design has been formed in advance, and after spraying fine particles exhibiting retroreflective properties, the adhesive is dried. In this way, a fashion product having a design design and a hidden design can be obtained. Or you may use the coating material with which the microparticles | fine-particles which show retroreflective properties were mixed beforehand. There is no restriction | limiting in particular in a printing method, Various printing methods, such as letterpress printing, intaglio printing, flat plate printing, inkjet printing, can be used.

  5 (a) and 5 (b) are cross-sectional views illustrating the principle of action of fine particles exhibiting retroreflectivity. In these drawings, light is incident on the same fine particle from different directions.

  The fine particles 12 are minute transparent spheres (beads) made of glass, acrylic resin, or the like, and a reflective film 12a is formed on the hemisphere thereof by metal deposition or the like. The metal vapor deposition film is originally opaque, but becomes transparent when made extremely thin. If the fine particle 12 is viewed as a convex lens, the focal point is outside the fine particle 12, but the distance between the surface of the fine particle 12 and the focal point becomes closer as the diameter of the fine particle 12 becomes smaller. Therefore, if the reflection film 12a is formed with the fine particle 12 having a minimum diameter, the parallel light incident on the surface of the fine particle 12 from each direction is reflected on the reflection film 12a by refraction as shown in FIGS. 5 (a) and 5 (b). The light is converged, reflected and diffused in the opposite direction, and recursed by a process of refraction and convergence again on the incident surface to return to parallel light.

  The hidden design 11 is expressed by the local surface density of the fine particles 12 when the fine particles 12 are dispersed in the design sheet 2 (or the base product). That is, a region where the fine particles 12 are fixed at a high density in the design sheet 2 is a hidden portion 11a of the hidden design 11, and a region where the fine particles 12 are fixed at a low density (including a density of 0) is a hidden portion 11b of the hidden design 11. It becomes.

  FIG. 5C is a cross-sectional view of an example of a design sheet to which fine particles are fixed. In this example, the left portion where the fine particles 12 are fixed at high density is the hidden portion 11b of the hidden pattern 11, and the right portion where the fine particles 12 are fixed at low density is the dark portion 11b. In this example, all of the fine particles 12 are fixed (semi-embedded) to the design sheet 2 with the hemisphere without the reflection film 12a exposed. In this way, since the retroreflection occurs in the large number of fine particles 12, the hidden design 11 can be clearly seen.

  FIG. 5D is a cross-sectional view of another example of a design sheet to which fine particles are fixed. Also in this example, the left side portion where the fine particles 12 are fixed at high density is the hidden portion 11a of the hidden pattern 11, and the right portion where the fine particles 12 are fixed at low density is the dark portion 11b. In this example, the fine particles 12 are fixed to the design sheet 2 in a random direction. However, even if it does in this way, since the number of the fine particles 12 is enormous, retroreflection occurs at a certain rate, so that there is no problem in the visibility of the hidden design 11.

  Note that even the bright portion 11a of the hidden design 11 is not completely covered by the fine particles 12, and there is a gap, so that the design design 10 on the back side can be seen naturally under normal light. Further, since the reflection film of the fine particles 12 does not reflect all light but partially transmits it, the design pattern 10 on the back side can be seen through the fine particles 12 under normal light. For this reason, the hidden design 11 exhibits transparency to normal light.
