Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a decorative display having transparency.

(Prior Art) As a conventional transparent display element, a transparent synthetic resin plate or a glass plate or other base material surface is formed by printing or painting an appropriate image such as a picture or a character with a desired colorant. It was displayed. However, with these display plates, when viewed from one side, a normal image can be viewed, but when viewed from the other side, left-right reversed images are viewed. Therefore, an appropriate image in the opposite direction on the transparent substrate surface,
After forming characters by printing, etc., a solid hiding layer is formed from above with a bright color hiding colorant such as white ink, and then an appropriate image in the forward direction is printed on it by printing or the like. By forming the display body, the images on the front and back are overlapped so that they cannot be viewed, and the images can be viewed in the normal direction. However, in this case, since there is a solid hiding layer in the area where the image is formed, the opposite side cannot be seen through the image area.

(Purpose of the Invention) The present invention, when a display is formed using a transparent substrate and a colorant, allows the opposite side to be seen through the image area formed on the display, and the images on the front and back of the display are It is intended to provide a novel decorative display member which is not overlapped with each other and viewed, and in which an image is formed by using a heat-sensitive or light-sensitive discoloration discolorable colorant.

(Structure of the Invention) The present invention provides a first colored layer and a masking layer, or a first colored layer on a transparent substrate.
A transparent display having a net-like or dot-like colored layer in which a colored layer, a masking layer, and a second colored layer are laminated in this order, in the first colored layer or / and the masking layer or / and the second colored layer. A heat-sensitive or light-sensitive coloring discoloration / erasing area is provided.

Also, the present invention provides a decorative display body having a see-through property, characterized in that the heat-sensitive or light-sensitive color-change discoloration area is formed by using heat-sensitive or light-sensitive color materials that act on light having different temperatures or different wavelengths. is there.

(Effect of the Invention) The present invention has a net-like structure in which a transparent substrate is provided with a first colored layer and a masking layer, or a first colored layer and a second colored layer are laminated with a masking layer sandwiched therebetween.
Since the dot-shaped laminated colored layer is provided, the opposite side of the display can be seen through the see-through portion having the reverse pattern of the mesh-shaped and dot-shaped laminated colored layer. Further, the first or second colored layer having the same or different patterns or characters on the front side or front and back sides of the concealing layer of the laminated colored layer, or the concealing layer is formed of a heat-sensitive or photosensitive color-change discolorable color material Since it is formed by applying, the coloring agent is colored or colored by touching the colored area from the front surface or the back surface of the display body with fingers, contacting warm air, or lighting and irradiating ultraviolet rays. The display image can be enjoyed as a variable image by changing the color or erasing the color.

(Embodiment) Referring to the drawings, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. A colored layer formed by laminating a first colored layer 2, a hiding layer 3, or a first colored layer 2, a hiding layer 3, and a second colored layer 4 in this order on a transparent substrate 1 made of reticular or dot-shaped. a is provided. Then, a see-through part b on which the coloring layer is not applied is formed in the pattern portion opposite to the net-like or dot-like pattern portion of the coloring layer a.
The first colored layer 2 of the colored layer a, or the concealing layer 3 and the second colored layer 4 are a printing ink used for ordinary printing, a thermosensitive color change and a decolorizable thermosensitive ink (thermochromic ink) and a photosensitive color change. It is formed by using a decolorizable photosensitive ink (photochromic ink), or by using a normal printing ink and any one of a thermal ink and a photosensitive ink. An image such as a pattern or a character formed by the thermal ink or the photosensitive ink is formed on the entire area or a partial area of the colored layer a. Further, it may be formed so as to be overlaid on the first colored layer, the concealing layer, the second colored layer, etc. in the colored layer a formed by the normal printing ink. In addition, a transparent protective plate of the same quality as that of the base material 1 may be laminated and stuck on the base material 1 from the side of the colored layer a. As the first colored layer 2 and the second colored layer 4 of the colored layer a formed on the base material 1, a monochromatic or multicolored line drawing, a gradation reproduction image, or the like can be displayed and formed. As the thermochromic ink, an ink containing spiropyran, bisphenol A or the like as a developer, or a microencapsulated product thereof as a developer is used, and as the photochromic ink, an inorganic compound such as zinc sulfide is used. Alternatively, an ink can be used in which an organic compound such as hydrazone, stilbene, salicylaldehyde, spiropyran, and bianthrone is used as a color former, or those obtained by microencapsulating them are used as a color former.

As a method of forming the colored layer a on the base material 1, for example, a printing method such as a screen printing method or a transfer sheet provided with the colored layer a to be transferred is used, and the base material 1 is heated and applied. It can be formed by an appropriate means such as a transfer method of performing pressure transfer, or a combination thereof.

FIG. 2 is a partial plan view of an embodiment of the display device of the present invention, in which a transparent colored layer a is provided on a transparent substrate 1 and a transparent region having a reverse pattern (negative pattern) with respect to the colored layer a. Is provided with a see-through part b. And the colored layer a
For example, a triangular pattern c is applied to a partial area in the area of 3 by a thermal ink, and a circular pattern d is applied to the outside of the area by using a thermal ink that operates at a different temperature from the thermal ink used for the pattern c, for example. It is a thing. Further, as the patterns c and d, a photosensitive ink that is colored by ultraviolet rays may be used.

(Effect of the Invention) The present invention provides a laminated colored layer including a first colored layer, a concealing layer, and a second colored layer in a dot shape and a dot shape on a transparent substrate,
In the portion where the colored layer is not formed, a see-through portion having a reverse pattern (negative pattern) is formed with respect to the colored layer, so that when viewed from one side (for example, the front side) of the substrate, the one side Only images such as pictures and characters displayed by the first colored layer on the side can be viewed, and images such as pictures and characters displayed by the second colored layer on the other side (opposite back side) are hidden by the concealment layer. Therefore, the front and back images can be viewed without overlapping. In addition, since the colored layer is provided with an appropriate pattern of thermal ink or photosensitive ink,
It has the effect that the display pattern can be changed by changing the temperature of the display or irradiating it with ultraviolet light. It can be used for display devices, showcases for exhibition, interiors, and transparent materials for windows. It is of practical value.
