Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a label for a vehicle violating a traffic violation, and more particularly to a label for a vehicle violating a traffic violation (travel label) that is attached to the window surface of a vehicle such as a vehicle violating a parking violation. .

Technical Prelude to the Invention and Its Problems With the rapid spread of automobiles, the number of vehicles violating traffic laws, such as parking illegally, is rapidly increasing. A label indicating the number 18 is pasted on the window surface of such a parked vehicle.
Violators are required to report to the police station indicated on the label, have the label removed in the presence of officials, and at the same time pay a fine for violating the law.

Such labels have an acrylic or rubber adhesive layer on the back of a base material such as paper or film. There is a problem that 119 simply peels off by hand after being pasted on the window surface.On the other hand, if the adhesive layer is too strong, it will stick firmly to the window surface. However, there was a problem in that it could not be easily removed within the jurisdictional police station.

For this reason, there is a desire for a traffic label for anti-traffic vehicles that has a strong adhesive force while being affixed to the window surface, and that can be easily peeled off by law enforcement authorities.

As such a label for a vehicle violating a traffic violation, /: For example, Japanese Utility Model Application Publication No. 53-151398 proposes a T5 label in which one side of printed paper is coated with an ultraviolet curable adhesive. The label for traffic violations disclosed in Japanese Utility Model Publication No. 53-151398 does not disclose what specific compound should be used as the ultraviolet curable adhesive.

In fact, trimedylolpropane triacrylate, tetramedylolmethanetetraacrylate, and pentaerythritol triacrylate are well known as ultraviolet ray compounds.

Pentaerythritol triacrylate, dipentaerythritol monohydroxypentaacrylate-1-, dipentaerythritol hexaacrylate or 1,4
- At least two photopolymerizable carbon-carbon double bonds in the molecule of butylene glycol diacrylate-1, 1,6-hekylene diol diacrylate, polyethylene glycol cyacrylate, commercially available oligoester acrylate, etc. The inventors have found that when using a compound having the above, there is a major problem that the adhesive may remain on the window surface of a car, or that the adhesive strength does not decrease sufficiently even when irradiated with ultraviolet rays. discovered.

Purpose of the Invention The present invention is an attempt to solve the problems associated with the prior art as described above. To provide a label for traffic violation vehicles that does not have adhesive remaining on the windshield surface of a vehicle due to the sharpness of the horn being sufficiently reduced, and that is adhered to the windshield surface with sufficient adhesive strength before being irradiated with ultraviolet rays. It is intended to.

A first label for a vehicle with a traffic violation according to the present invention is a label for a vehicle with a traffic violation in which a UV curable adhesive layer is provided on the end surface of the base material. The adhesive layer is characterized by consisting of an adhesive and a urethane acrylate oligomer.

Further, a second label for a vehicle violating a traffic violation according to the present invention is a label for a vehicle violating a traffic violation in which a layer of an ultraviolet curable adhesive can be seen on the back side of the substrate, in which the ultraviolet curable adhesive is an adhesive;
It is characterized by consisting of a urethane acrylate oligomer and a light-scattering inorganic compound powder.

In the traffic violation label according to the present invention, the label for traffic violation is provided with an ultraviolet curable adhesive layer on the back side of base + A, and the ultraviolet curable adhesive layer or adhesive and the urethane acrylate oligomer are necessary. Since it is composed of a light-scattering inorganic compound powder according to The adhesive strength is sufficiently reduced, so that the adhesive can be easily peeled off from the window surface of a car without any residual adhesive remaining on the window surface.

DETAILED DESCRIPTION OF THE INVENTION The label for traffic violation vehicles according to the present invention will be described below with reference to specific examples shown in the drawings.

As shown in FIG. 1, the label 1 for traffic violation vehicles such as parking violation vehicles according to the present invention is composed of a base vi2 and an ultraviolet curing adhesive layer 3 provided on the back surface of this base material 2. ing.

This traffic violation vehicle label 1 is the UV curing and [)
1. It is preferable that a release paper 4 is provided on the back side of the ultraviolet curable adhesive layer 3, if necessary, to protect the adhesive layer 3 until use.

Hayatsuki 2 specifically includes polyethylene film, polypropylene film, polyvinyl chloride film, polyethylene terephthalate film 1 to 1, polybutylene terephthalate film, and polybutene film 1. Synthetic resin films such as polyethylene film, polyurethane film, polymethylpentene film, ethylene acetate film, paper, synthetic paper, etc. are used. These substrates may be transparent or opaque.

Among these, synthetic resin film, synthetic paper, and water resistance are particularly preferred because they are widely used.

these! HJ2, especially synthetic resin film, synthetic paper, etc., can also contain an ultraviolet absorber.

On the front of the 2nd Form, necessary information such as the nature of the violation and the police station where the person should appear is printed or filled out.

On the back surface of such a base material 2, as shown in FIG. 2, a light shielding element 5 is provided as necessary.

This light-shielding layer 5 serves to prevent ultraviolet rays contained in sunlight from reaching the violet Tato ray-curable adhesive layer 3, and specifically includes metal foil, metal vapor deposited film, A resin coating containing an ultraviolet absorber, a side fat coating, an ultraviolet filtration substance, and the like are used.

The metal foil or (sting fat coating) as the light shielding layer 5 is the base material 2.
It can be formed by bonding a metal foil or a resin film with an adhesive.

Further, the metal vapor deposited film as the light shielding layer 5 can be formed by vapor depositing a metal on the back surface of the group +A2 according to a conventional method. Further, in step 1, a composition containing an ultraviolet absorber or an ultraviolet irradiant substance and a base (or a lubricant) is prepared; Apply this ink composition to the back surface of the base material 2.
It can also be formed by 5'.

The ultraviolet curable compound 1εj3 used in the present invention is formed including an adhesive and a urethane acrylate oligomer as an ultraviolet curable compound.

As the adhesive, conventionally known λ1j adhesives can be widely used, or acrylic adhesives are preferable, and specifically, those selected from homopolymers and copolymers having acrylic ester as the main monomer unit. These include acrylic polymers, copolymers thereof with functional monomers, and mixtures of these polymers. For example, examples of acrylic esters include ethyl methacrylate, butyl methacrylate, 2-ethylhexyl methacrylate, glycidyl methacrylate, 2-hydroxyethyl methacrylate, and the above-mentioned methacrylates. For example, those in which acrylic acid is replaced with acrylic acid can also be preferably used.

Furthermore, ultraviolet curing described below [In order to increase the compatibility as a single compound, the above acrylic acid ester and a sulfuric acid such as (meth)acrylic acid, acrylonitrile, acetic acid, and nil may be co-merized. . The molecular weight of the acrylic polymer polymerized from these seven polymers is 2.0.
X105 to 10.0X]○, preferably 4.
0X105 to 8.0XIO''.

In the present invention, a urethane acrylate oligomer is used as the ultraviolet curable compound. Urethane acrylate oligomers are used. The urethane acrylate oligomer is made of a polyester or a polyol compound such as a polyether type, and a poly(isocyanate compound such as 2.4-1-lylene diisocyanate, 2.6
-Drylene diisocyanate, 1,3-xylylene diisocyanate, 1゜4-xylylene diisocyanate,
For example, is a (meth)acrylate having a hydroxyl group added to the isocyanate-terminated urethane prepolymer prepared by reacting diphenylmethane 4,4-diisocyanate or the like? - hydroxyethyl (meth)acrylate,
iQ is produced by reacting 2-hydroxypropyl (meth)acrylate 1~, polyethylene 1-nocol (meth)acrylate, and the like. This urethane acrylate oligomer is an ultraviolet polymerizable compound having at least one carbon-carbon double bond.

This J: urethane acrylate oligomer has a molecular weight of 3,000 to 10,000, preferably 400.
If you use a product with a rating of 0 to 8000, even if the car window surface is uneven, there will be no adhesive (=J) on the window surface when peeling off the traffic label from the window surface. Preferably, when such a urethane acrylate oligomer is used as an ultraviolet curable compound, the number of photopolymerizable carbon-carbon double bonds in the molecule is reduced as disclosed in JP-A-60-196.956. Compared to the case of using a low molecular weight compound having 52 or more molecules, a far superior traffic violation label can be obtained.In other words, the adhesive strength of the label before irradiation with ultraviolet rays is sufficiently strong. Furthermore, after irradiation with ultraviolet rays, the adhesive strength is sufficiently reduced so that no adhesive remains on the window surface when the label is peeled off.

The blending ratio of the adhesive and the urethane acrylate oligomer in the adhesive in the present invention is from 10 to 901ffi.
urethane acrylate oligomer is 90~
It is preferable that the suspension be used with a suspension of 100 to 10 ω. In this case, the obtained traffic violation label has a high initial adhesive strength, but the adhesive strength is greatly reduced after irradiation with ultraviolet rays, and the label can be easily peeled off from the window surface.

In addition to the above-mentioned adhesive and ultraviolet curable compound, such an ultraviolet curable adhesive layer 3 can also contain a light scattering inorganic compound powder.

This light-scattering 1'1 barless compound is
) is a compound that can diffusely reflect the ultraviolet rays when it is illuminated, and specifically, silica powder, alumina powder, silica alumina powder, myj
J I'! I) End etc. are exemplified. The light-scattering inorganic compound is preferably one that almost completely absorbs ultraviolet rays as described above, but it is also possible to use compounds that absorb ultraviolet rays to some extent.

Light scattering power
It is desirable that the This light-scattering inorganic compound is contained in the adhesive 4-1 in an amount of 0.1 to 10%, preferably 1 to 10%.
It is desirable to use 4 weight + 36 scales. If the compound is used in the adhesive layer in a concentration exceeding 10% by weight, the adhesive strength of the adhesive layer may be reduced, so it is preferable to use it, whereas if it is less than 0.1% by weight, it is preferable. However, even if the label is irradiated with ultraviolet rays, the adhesive strength may not be sufficiently reduced, and the adhesive may remain on the window surface when the label is removed, which is not preferable.

Adding light-scattering inorganic compound powder to adhesive layer/Jrl v
When UV rays are irradiated onto the traffic violation vehicle label obtained by this process, the irradiated UV rays collide with the compound and change direction before reaching the window. Therefore, the diffusely reflected ultraviolet rays sufficiently penetrate into the depths of the adhesive layer, so that the adhesive layer is sufficiently cured in all parts. Therefore, by adding an inorganic compound powder to the adhesive layer to prevent light scattering, the adhesive will not adhere to the window surface when the traffic violation vehicle label is peeled off.

Further, by mixing an isocyanate curing agent into the above-mentioned pressure-sensitive adhesive, the initial adhesive strength can be set to an arbitrary value. Examples of such curing agents include polyhedral isocyanate compounds, such as 2°4-tolylene diisocyanate, 2,6-tolylene diisocyanate,
1,3-xylylene diisocyanate, 1,4-xylylene diisocyanate, diphenylmethane-4,4'-diisocyanate, diphenylmethane-2,4-cyisocyanate-1, 3-mebuldiphenylmethane diisocyanate, Kirimethylene diisocyanate, isophorone diisocyanate, dicycloxylmethane-4,4-
Diisocyanate, dicyclohexylmethane-2,4'
-Diisocyanate, lysine isocyanate, etc. are used.

Furthermore, by incorporating a UV initiator into the above-mentioned pressure-sensitive adhesive, the manual curing time and the amount of UV irradiation due to UV irradiation can be reduced.

Specifically, such UV initiators include benzoin, benzoin methyl ether, benzoin ethyl ether, benzoin isopropyl ether, penzyl diphenyl lylphide, tetramethyldiuram monosulfide, azobisisobutyronitrile, dibenzyl , diacetyl, β-chloroanthraquinone, and the like.

In the traffic violation vehicle label 1 according to the present invention, as shown in FIG. 3, the light shielding layer 4 can be formed by partially providing a peeling 811 layer 6 on the inner surface of the base material 2.

If this J: Una peeling N6 is provided, if an attempt is made to unduly remove the traffic violation label 1, the light shielding layer 4 and the adhesive layer 3 will remain on the window surface 7, as shown in FIG.
The fact that it was unfairly removed can be easily destroyed.

Hereinafter, how to use and pay for the traffic violation vehicle label according to the present invention will be explained.

If the label 1 for traffic violation vehicles according to the present invention is provided with a release paper (not shown), the release paper is removed and the label 1 is placed on the window surface 7 of the automobile. On this occasion,
It is also possible to write the details of the violation on the surface of the base material 2.

When a violative vehicle appears at the designated enforcement jurisdiction, as shown in Figure 5, an ultraviolet ray irradiation device 8 illuminates the ultraviolet curable adhesive layer of the label with ultraviolet rays 9 from inside the vehicle.
After reducing the adhesion of the label to the window surface,
Peel the label from the window surface.

Effects of the Invention In the label for a vehicle violating a traffic violation according to the present invention, the label for a vehicle violating a traffic violation is provided with an ultraviolet curable adhesive layer on the back side of the base material. Since it is composed of a light-scattering inorganic compound and a light-scattering inorganic compound if necessary, it has sufficient adhesive strength before applying ultraviolet rays to the ultraviolet curable adhesive layer. After being exposed to light for 1 hour, the viscosity is sufficiently reduced, and the adhesive can be easily peeled off from the window surface of the car without any residual adhesion.

The present invention will be explained below with reference to examples, but the present invention is not limited to these examples.

Coating 1 (i) was dried, and a release paper was temporarily attached for protection to form a label for a parking violation vehicle.

When this parking violation label was pasted on the window of a car, it was difficult to remove by hand, but ultraviolet rays were passed through an air-cooled high-pressure mercury lamp ( 80w/cm, light
When irradiated for 2 seconds at a distance of 10c+), it could be easily peeled off by hand.

Example 2 Hitomi [0.3% benzotriazole-based ultraviolet absorber or gland absorbent was applied to the back side of a vinyl chloride base material (38 μm thick) with raw material.
Apply the added PVC resin to a thickness of 5μ7n as a light shielding layer1.
J was formed, and then an adhesive containing 2.5 parts of fine silica powder (0K-412 manufactured by Degumasu Co., Ltd.) was added to an adhesive made of the same acrylic adhesive and urethane acrylate oligomer as in Example 1. 21i was coated to a dry film thickness of 25 μm to form a label for a parking violation vehicle.

Using this label, a test was conducted using the same method as in Example 1), and it was found that even if the purple Tato line light Q; It was obvious.

Example 3 Transparent January 4 pieces Polyethylene terephthalate 1~(50μ?f
On the back side of the 3μ7 thick alkyd resin with 50 parts of silicone release agent added in a character pattern,
After partially coating the film, aluminum was vapor-deposited to form a light-shielding layer. On the back side of the light-shielding layer, a polygonal adhesive layer made of the same acrylic adhesive and urethane acrylate oligomer as used in Example 1 was formed to create a label for a parking violation vehicle of the present invention. When the same test as in Example 1 was conducted, it was found that the label could be removed by hand, and the part where the release layer was formed had some residue on the glass surface, such as the light-shielding layer and the adhesive, and these could not be removed by hand. . In addition, by shining ultraviolet rays on the sticker surface for 2 seconds from the inside of the window, it was possible to remove them by simply rubbing them off.
