Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a partial hologram in which a hologram image exhibiting a three-dimensional aesthetic appearance can be arbitrarily and easily introduced into a design or pattern obtained by ordinary printing or coating. Is.

2. Description of the Related Art As is well known, a hologram irradiates an object with two kinds of laser light, an object light and a reference light at the same time, and at this time, an interference fringe generated by a positional deviation of the light is utilized.
This is recorded on a special film or plastic plate. With this hologram, it is possible to represent a three-dimensional pattern or image that was impossible in the past.

However, the commercially available hologram foils and films are often expensive, and therefore, they are often used at one point or only at a specific place in a printed matter or a coating, rather than being used alone. . However, the combined use of holograms with other printing designs, etc., in combination with such designs, was able to exhibit extremely high visual effects.

Generally, as a method of introducing a hologram into a printed material or a coating material, an adhesive layer or a heat sealing agent layer is formed on the back surface of the hologram foil or the hologram film in advance, and the printed surface or coating of the substrate is formed. A method of sticking the above-mentioned hologram foil or hologram film on the surface or thermally transferring it has been adopted.

[0005]

However, in this method, as described above, it is necessary to previously form an adhesive layer or a heat sealing agent layer on the back surface of the hologram foil or the hologram film to prepare a label material or a transfer foil material. In addition, this label material or transfer foil material must be punched into a desired shape. In addition, the stamped label material or transfer foil material must be attached or foil-pressed at a predetermined position. As described above, the conventional method described above has a problem that the workability is extremely poor and the manufacturing cost is high.

Further, the shape thereof is also limited. That is,
When the hologram image is introduced only into the minute portion, the above-mentioned punching process (work) becomes extremely difficult, and the workability is further deteriorated in the subsequent sticking work or foil stamping work. Or the accuracy deteriorates. On the other hand, even for a large area, the transfer foil material requires a foil stamping machine corresponding to the large area, which is practically impossible.

[0007]

The present invention has been proposed in view of the above, and after forming a transparent or semitransparent hologram layer on a substrate, printing or coating is partially performed on the surface of the hologram layer. The present invention relates to a method for producing a partial hologram (hereinafter, referred to as the first invention), characterized in that the unevenness on the surface of the hologram layer is partially eliminated by the printing layer or the coating layer.

The base material used in the first invention may be any material such as paper, metal, plastic, etc., and its shape is not particularly limited and may be a sheet shape or a thick molded article shape. Not a thing.

In the first invention, first, a transparent or semitransparent hologram layer is formed on the base material. Any known method may be used for this forming method. For example, a thermoplastic resin which is transparent or semitransparent by admixing pigments or the like by attaching a plate having engraved hologram irregularities to the roll surface. A method of transferring to a layer or the like, and further forming a coating layer such as a metal vapor deposition layer having a high refractive index, which is transparent or semitransparent, may be adopted if necessary. In addition, a commercially available hologram foil or hologram film is used as a transfer plate, and a transparent or pigment is mixed with a support film to form a translucent ultraviolet (or electron beam) curable resin (liquid) layer. After pressure-bonding and irradiating with ultraviolet rays (or electron beams) to cure, peel off the commercially available hologram foil or hologram film, and if necessary, a coating layer such as a metal vapor deposition layer that is transparent or semitransparent and has a high refractive index. Method of formation (= Japanese Patent Application No. 4 proposed by the present inventor
-73218) may be adopted.

Then, partially (at a predetermined location designed in advance) on the surface of the transparent or translucent hologram layer.
It is printed or coated. For this printing or coating method, known screen printing, offset printing, gravure printing, flexo printing,
Printing or coating may be carried out by any method such as letterpress printing, coating using a roll coater, gravure coater, flexo coater, spray coating, dipping coating, spin coating, or the like.

As described above, the processing operation of the first invention is extremely simple, and the product obtained by the first invention has a printing layer or coating layer partially applied to the surface of the hologram layer. Since the irregularities are eliminated, the hologram becomes a partial hologram in which the hologram image can be seen only in the portion where the printing layer or the coating layer is not provided.

In the first aspect of the present invention, the printing or coating is formed on a predetermined portion designed in advance as described above. However, the treatment can be easily performed on a fine and complicated plane shape or a large area. Since it can be applied, it can be applied to any desired design, and a visually appealing product can be produced. Moreover, in the first invention, although there are some differences depending on the specific printing method or coating method, the processing accuracy is high and the mass productivity is at least higher than that of the method using the conventional label material or transfer foil material described above. high.

If, for example, a base material having a sheet or plastic sheet on which an adhesive layer or a pressure sensitive adhesive layer is previously formed is used as a base material, the obtained product is used as a label material or a transfer foil material. Can also be used as

Further, in the present invention, a transparent or semitransparent hologram layer is formed on a supporting film, an adhesive layer is formed on the back surface, and the supporting film is laminated on a substrate, and then the hologram layer is formed. The partial hologram is produced by partially printing or coating the surface of the hologram layer so that the irregularities on the surface of the hologram layer are partially eliminated by the printing layer or the coating layer (hereinafter referred to as “second hologram”). The invention is also proposed).

The supporting film and the adhesive (layer) used in the second invention are not particularly limited in their material and other properties, and any known one can be used. Further, other methods and the like may be performed according to the method described in the first invention.

The second aspect of the present invention is, for example, when the hologram layer cannot be formed on the substrate due to the shape, that is, the first aspect.
The invention is used in a mode in which the invention cannot be applied, and may be appropriately selected and applied in consideration of practical conditions and the like.

Further, in the present invention, a transparent or semi-transparent hologram layer is formed on the back surface of the support film, an adhesive layer is formed on a base material having an empty space, and the support film is attached on the base material. The present invention also proposes a method for manufacturing a partial hologram (hereinafter, referred to as a third invention), characterized in that the unevenness on the back surface of the hologram layer is partially eliminated by the adhesive layer by combining them. .

In the third aspect of the invention, a void having a desired shape is previously formed on a base material, and an adhesive layer is formed on the base material by an appropriate method. Next, a support film having a transparent or semitransparent hologram layer formed on the back surface is attached to the front surface of the adhesive layer to produce a partial hologram. A known heat-sealing method or the like can be used as the method for laminating the support film, and the method is not particularly limited, but the adhesive layer on the base material is heat-melted (softened) to be formed on the back surface of the support film. Since the irregularities of the transparent or semitransparent hologram layer thus formed are eliminated, the hologram image becomes a partial hologram in which the hologram image can be seen only in the portion where the adhesive layer is not provided, that is, in the empty portion of the base material.

In the present invention, a transparent or semi-transparent hologram layer is formed on a support film, an adhesive layer is formed on a base material having an empty space, and the support film is laminated on the base material. After that, by partially printing or coating the surface of the hologram layer, the unevenness of the surface of the hologram layer is partially eliminated by the printing layer or the coating layer. It also proposes a manufacturing method (hereinafter referred to as the fourth invention).

In the fourth aspect of the invention, similarly to the third aspect of the invention, a void having a desired shape is formed in advance on the base material, and the adhesive layer is formed on the base material by an appropriate method. Next, a support film having a transparent or semitransparent hologram layer formed on the surface thereof is attached to the surface of the adhesive layer. Further, the transparent or semitransparent hologram layer of the support film is partially printed or coated on the surface thereof to produce a partial hologram. That is, in the fourth invention, as in the first and second inventions, the printing layer or the coating layer partially applied to the surface of the hologram layer eliminates the unevenness of that portion. It becomes a partial hologram in which the hologram image can be seen only at the place where no layer is provided.

Further, in each of the first to fourth inventions, a method of manufacturing a partial hologram in which a semitransparent or opaque metal vapor deposition layer is formed on the other surface side of the hologram layer on which irregularities are formed (hereinafter referred to as the fifth invention). That)) is also proposed.

In this method, a metal is vapor-deposited so as to be semitransparent or opaque on one side of the substrate or one side of the support film in the first to fourth inventions, and a partial hologram is formed by the above-mentioned method. Just make it. Reflectivity may be imparted by forming the metal vapor deposition layer in this manner. When the metal vapor deposition layer is provided in the third invention, the metal vapor deposition layer is located above the hologram layer. Therefore, a semi-transparent metal vapor deposition layer may be provided, or a metal vapor deposition layer may be partially provided at a predetermined location to hide the hologram image at that location.

As described above, in the first to fifth inventions of the present invention, a hologram is easily introduced into a pattern or a pattern formed by various printing or coating, and the hologram is selected according to the shape and design of the substrate to be formed. A mode may be appropriately selected and implemented.
