Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an exterior hologram seal with excellent weather resistance.

[Conventional technology and the problem to be solved by the invention]

Jurai's holograms and stickers, which can be freely pasted on desired places and items to reproduce hologram images, can be used as an exterior for parts of vehicles, building windows, etc., and are protected against sunlight, etc. This causes problems such as discoloration and peeling of the seal as it deteriorates over time.

Such problems often occur because conventional bologram seals are made of a general-purpose plastic film base material, which lacks weather resistance. A measure was taken to coat the surface of the affixed PoCl Gram sticker with a weather-resistant resin, but this method had the disadvantage of poor workability as it used solvents during coating, and it also required painting equipment. There was a problem that it was complicated.

In addition, in the past, there was a hologram J and transfer foil that could be transferred to a desired location, article, etc. and reproduce a hologram image in the same way as a bologram sticker, but the transfer body using this transfer foil is generally Since the layer P1 is thin, it has poor abrasion resistance and weather resistance, and it is difficult to impart weather resistance to itself.Furthermore, a transfer processing machine is required for transfer, so the work is not easy. there were.

The present invention has been made in view of the point -F, and it is an object of the present invention to provide a hologram seal for exterior use that has excellent weather resistance and is extremely easy to handle.

[Means to solve the problem]

The gist of the present invention is an exterior hologram seal, characterized in that a hologram forming layer, a hologram effect layer, and an adhesive layer are sequentially provided on a weather-resistant plastic film base material.

The hologram used in the present invention is a so-called "transparent hologram" which does not hide the display part located below the hologram forming layer 3, or a so-called "transparent hologram'°" which does not hide the display part located below the hologram forming layer 3. , so-called "reflection holograms" and the like are mentioned.

As the material for the hologram forming layer 3, a thermoplastic 1'l resin, a hardened thermosetting resin, or a mixture of the above thermoplastic resin and thermosetting resin can be used.

Other maturing substances having radically polymerizable unsaturated groups can also be used, and specific examples include ultraviolet curable resins and the like.

The hologram forming layer 3 can be formed by coating the resin on the base material 2 and then performing heat embossing to form a hologram image, or it can be formed by a conventionally known method. can. ``The hologram effect layer 4 is formed on the hologram forming layer 3, and is a layer having a function of increasing the hologram effect. The effect layer 4 can be opaque or transparent (in the case of opacity, the hologram formation N3
becomes a reflection hologram, and in the case of transparency, the hologram forming layer 3 becomes a transparent hologram.0 The opaque effect layer 4 used for the reflection hologram is I7S200.
~aOO people, preferably 300-400 people, metal thin layer. Examples of the material include metals such as aluminum, chromium, antimony, copper, and silver, and alloys thereof. Aluminum and chromium are usually used, and chromium is particularly preferred when weather resistance is considered.

Examples of the transparent effect layer used in the transparent hologram include a transparent material having a different refractive index from that of the hologram forming layer, and a metal layer having a thickness of less than 200 mm. In the former case, the refractive index may be larger or smaller than that of the hologram resin layer, but if the refractive index is 0.
．． It is preferably 1 or more, more preferably 0. 5 or more, but rr: must be greater than 1.0. or,
In the latter case, although it is a thin metal film, the thickness is less than 200 mm, so the transmittance of light waves is high, and as a result, the hologram effect is produced and the lower part of the display area, etc. ! Produces a shielding effect. Examples of the material for the above layer include the following.

(1) A transparent layer with a higher refractive index than the hologram forming layer. VB').

(2) A transparent ferroelectric material with a higher refractive index than the hologram forming layer.

(3) A transparent continuous thin film with a lower refractive index than the hologram forming layer.

(4) A fully reflective thin film with a thickness of 200 Å or less.

(5) A resin having a different refractive index from that of the hologram forming layer.

(6) A laminate formed by appropriately combining the materials listed in (11 to (5)) above.

The above materials (+) to (5) may be combined arbitrarily, and the vertical positional relationship of each layer in the layer structure may also be arbitrarily selected. Among the effect layers of (+) to (6) above, the thickness of the effect layer of (4) is less than 200 people, but the thickness of the effect layer of (+) to (3), (5), and (6) is less than 200 people. may be a transparent region of the material forming the thin film, and is generally preferably 10 to 10,000 people, more preferably 100 to 5,000 people.

The method for forming the effect layer 4 is a vacuum vapor deposition method when the effect layer is the above-mentioned full-bending vapor deposition layer or the materials listed in (1) to (4) above;
