[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to labels, stickers, stripes and the like used for decorative purposes. The present invention relates to labels, stickers, stripes, and the like, which can retain their original appearance, especially when applied to a substrate while being thermally stressed or stretched.

[0002]

2. Description of the Related Art
Some films or composites are known that can protect the substrate or impart a decorative appearance, such as a metallic appearance, to the substrate. A composite material obtained by depositing a metal such as aluminum, chromium, tin or the like on a polyester film or a similar film or having a pressure-sensitive adhesive or an adhesive is known as CH-2 film manufactured by 3M Corporation. Due to the characteristics of the films, these films had poor followability on a curved surface, and could be practically applied only to a quadratic curved surface (they could be applied only to a square having a side of 3 cm on a sphere having a diameter of 15 cm). Recently, there is a hologram pattern reproduced on a PET (polyethylene terephthalate) film or a material similar thereto, and a hologram pattern is reproduced on the hologram pattern. It could not be attached to a substrate with a curved surface.

Japanese Patent Application Laid-Open No. 2-64187 discloses a metallic glossy adhesive film using a fluorine-containing resin film.
Although this film has flexibility, it has many fish eyes due to the use of fluorine-containing resin, so even if it is used for hairline processing or forming a hologram pattern, it is not possible to obtain a commercially valuable clean product,
Also, it is necessary to plasma-treat the surface during printing,
There is a problem that the price is high.

Japanese Patent Application Laid-Open No. 3-140242 discloses a decorative composite material using a radiation-curable resin for a stabilizing layer of a metal deposition layer. There are problems that an apparatus is required and that heat resistance is generally poor.

[0005]

The objects of the present invention are as follows. (A) good followability to a three-dimensional curved surface, (b) excellent heat resistance, (c) when there is a decorative layer, excellent adhesion between the decorative layer and the stabilizing resin layer, (d) beautiful hairline treatment, When the hologram processing is required, it is possible to provide the decorative sheet which is (e) inexpensive and (f) does not require an irradiation device.

[0006]

According to a first aspect of the present invention, there is provided:
In a decorative sheet including a stabilizing resin layer and a decorative layer, the present invention provides a decorative sheet in which the stabilizing resin layer is a polyurethane resin having a siloxane bond in a molecule. In the present invention, "sheet" is a concept including a so-called sheet or film.

A second aspect of the present invention is a decorative sheet including a stabilizing resin layer and a hologram-treated surface or a hairline-treated surface, wherein the stabilizing resin layer is a polyurethane resin having a siloxane bond in a molecule. Make a summary.

[0008] In addition, the present invention can include a pressure-sensitive adhesive layer and / or a support layer depending on the mode of use.

The components of the present invention will be described below.

[0010] The stabilizing resin layer in the present invention mechanically holds the decorative layer when the decorative sheet is stretched while being heated at room temperature or up to about 160 ° C to conform to a three-dimensional curved surface. It has a function to do. It also has a function as a mechanical support layer when a decorative layer or a decorative surface is provided on the decorative sheet.

In the present invention, the use of a polyurethane resin having a siloxane bond in the molecule for the stabilizing resin layer is based on the following reasons.

(A) Due to the properties of the siloxane bond and the urethane resin, the extensibility is excellent. Therefore, the ability to follow a three-dimensional curved surface is extremely good.

(B) Since it has a siloxane bond in the molecule, it has good heat resistance. Therefore, specifically, 160
It can withstand temperatures of ~ 260 ° C.

(C) Since there is a hydroxyl group linked to silicon in the molecule, when there is a decoration layer, it reacts partially with the decoration layer, mechanically reinforces the decoration layer, and improves the adhesion to the decoration layer. . Therefore, even if the decorative film is stretched while being heated, there is no possibility that microcracks will occur in the decorative layer and whitening will occur.

(D) The heat resistance of the stabilizing resin layer is high, and when the decorative layer is provided, the adhesion to the decorative layer is excellent. As a result, the control of the vapor deposition step and the embossing step becomes easy, and no siloxane bond is contained. Metallization, hairline processing, and hologram processing can be performed beautifully and with high reproducibility, as compared with the conventional urethane resin.

(E) It is inexpensive as compared with conventional expensive fluorine-based resins.

(F) Further, unlike a radiation-curable resin, a radiation device is unnecessary, the dispersion is small, the reproducibility is good, and the resin can be easily produced.

The siloxane bond in the urethane resin containing the siloxane bond in the molecule means a -Si-O- unit, and in the present invention, it is preferable that this unit has a repeating unit of 1 to 1,000. This is because the heat resistance of the urethane resin is improved if there is at least one siloxane bond, while if it exceeds 1,000, the reactivity between the hydroxy group and the isocyanate group in forming the urethane bond is greatly reduced.

The term "urethane resin" as used herein means a resin having a urethane bond in the molecule. Specifically, it can be obtained by reacting a hydroxyl group such as a polyol with an isocyanate group. In particular, a crosslinked urethane resin has good heat resistance and can be suitably used in the present invention.

The polyol is a compound having two or more hydroxy groups in a molecule, and includes diol, triol and the like. The polyol used in the production of the urethane resin containing a siloxane bond in the molecule used in the present invention is disclosed in
Polyols having a siloxane bond in the molecule and having a diol or a triol at the terminal described in -97868 are preferable. Further, a polysiloxane having two or more alkoxy groups bonded to a silicon atom which is easily hydrolyzed in the presence of water may be used. Since this polyol has a siloxane bond in the molecule, the resulting urethane resin has good heat resistance, oxidation resistance, elongation and surface properties. Furthermore, it has good adhesion and adhesion to metal, glass, etc., and is particularly suitable for the decorative sheet of the present invention. Furthermore, since it has a hydroxy group at the terminal, it has good reactivity with isocyanate groups and can use a polyol having a wide range of molecular weights. Because it can be used.

In addition, the polyol suitable for the present invention may have various functional groups introduced therein, for example, polyester, polyether, carboxyl, phenyl, methyl, ethyl, acryl, amino groups and the like. This is because heat resistance, adhesive strength, elongation, and the like can be controlled as a decorative sheet. Particularly, polyols having a benzene ring described in JP-A-4-41493, for example, 1,3-bis (p-hydroxybenzyl) -1,1,3,3-tetramethyldisiloxane and derivatives thereof are particularly heat-resistant. It is suitable for the present invention in that the property is good.

The isocyanates suitable for the production of the urethane resin used in the present invention include aromatic, araliphatic, aliphatic and alicyclic isocyanates, for example,
Diphenylmethane-4,4'-diisocyanate (MD
I), tolylene diisocyanate (TDI), hexamethylene diisocyanate, isophorone diisocyanate, dicyclohexylmethane-4,4′-diisocyanate, naphthylene diisocyanate (NDI), and their terminal block types. These isocyanate trimers have excellent heat resistance,
In particular, trimers such as isophorone diisocyanate (IPDI) and hexamethylene diisocyanate (HDI) are suitable for the present invention because they have excellent heat resistance and can form a urethane resin that does not yellow.

By reacting the polyol and the isocyanate as described above, a polyurethane resin containing a siloxane bond in the molecule suitable for use in the present invention can be produced.

The thickness of the stabilizing resin layer in the present invention is not particularly limited, but is 0.1 to 500 μm when a support layer is separately provided, and 1 when no support layer is provided.
0 to 1000 μm is preferred. When a support layer is not separately provided, if the thickness is less than 10 μm, the effect of mechanical reinforcement is poor. If the thickness exceeds 1000 μm, three-dimensional followability is poor and the cost may be increased. On the other hand, when the support layer is separately provided, the thickness of the stabilizing resin layer can be reduced as compared with the case where the support layer is not provided.
If it is at least μm, the effect of the above-mentioned stabilizing resin layer can be obtained. Further, when a support layer is separately provided, if the thickness exceeds 500 μm, the thickness of the entire decorative sheet becomes thick, and the three-dimensional followability may be poor.

The decorative layer is defined as a layer having a decorative effect adjacent to the stabilizing resin layer, and is composed of a print layer, a metal thin film layer, a hologram layer, a hairline layer, etc., alone or in combination. The decorative layer may be provided on at least one surface of the stabilizing resin layer, and may be provided on both surfaces of the stabilizing resin layer. The effect of the present invention is remarkably obtained when a metal thin film layer, a hologram layer, or a hairline layer, of which heat resistance is a problem, is provided as the decorative layer.

Next, the decorative layer will be specifically described. The decorative layer includes a print layer, a metal thin film layer, a hologram layer, a hairline layer, or the like, alone or in combination.

(A) Printing layer: The printing layer is made of a vinyl chloride sheet or polyester sheet on which characters, symbols, figures, etc. are displayed with ink, decorative tape, or the like, or directly using ink or the like. It can be provided on the activated resin layer or the support layer. In particular, when a support layer is provided on a decorative sheet, the adhesion of ink or the like is generally good, which is preferable.

(B) Metal thin film layer: This layer is made of Al, C
r, Sn, Au, Ag, Ni, Ti, a metal such as TiO _2, metal oxide or made of a metal sulfide such as ZnS or the like. Although the thickness is not particularly limited, a thickness of 50 to 5000 angstroms is preferable in consideration of productivity, decorativeness, adhesion to the stabilizing resin layer, mechanical strength, and the like. This layer can be formed by a sputtering method, an electron beam method, a vacuum evaporation method, a plating method, a lamination method, or the like.

(C) Hologram layer: What is a hologram layer?
Depending on the viewing angle, the direction of light reflection and the amount of reflection are different,
Fine irregularities (hologram pattern) provided on the surface,
It is defined as a decorative layer that has been subjected to a so-called hologram process.
This layer can be provided by subjecting a polyester sheet, a polypropylene sheet, an acrylic sheet, a vinyl chloride sheet or the like to fine embossing.

(D) Hairline layer: The hairline layer is
It is defined as a decorative layer having a hairline pattern, and has a pattern such as a fine wavy, straight, or semicircular shape having a length of several μm or more and a depth of several Å to several μm on the surface. This layer can be provided by subjecting a polyester sheet, a polypropylene sheet, an acrylic sheet, a polyvinyl chloride sheet or the like to a fine polishing roll process.

When the present invention is used as a decorative sheet, it is practically preferable to provide a pressure-sensitive adhesive layer in advance, since the pressure-sensitive adhesive layer can be directly applied to a decorative base material. The position of the pressure-sensitive adhesive layer may be on the outer surface of the decorative sheet, and may be in contact with the decorative layer as shown in FIG. 1 or in contact with the stabilizing resin layer or the support layer as shown in FIGS. May be. When the pressure-sensitive adhesive layer is in contact with the decorative layer, the decorative layer can be protected from an enemy environment by the stabilizing resin layer or the support layer, so that the durability of the decorative layer is significantly improved. However, when the pressure-sensitive adhesive layer is in contact with the decorative layer, it is desirable that the pressure-sensitive adhesive layer be substantially transparent so as not to impair the decorativeness of the decorative sheet. In addition, when the pressure-sensitive adhesive layer is in contact with the stabilizing resin layer or the support layer and a vinyl chloride resin is used for the decoration layer,
Although a plasticizer is indispensable for the decorative layer, it is possible to prevent a decrease in adhesive strength due to bleeding of the plasticizer.

For the pressure-sensitive adhesive layer, specifically, an acrylic, urethane-based, epoxy-based, rubber-based, silicone-based adhesive or the like can be used. In particular, a silicone-based adhesive or the like is suitable for the present invention because of its high heat resistance, good elongation, and good adhesion to the stabilizing resin layer. In addition,
In addition, a filler, a cross-linking agent, a reinforcing material, and the like can be added to the pressure-sensitive adhesive layer of the present invention in order to improve heat resistance, concealing property, and handleability.

Although the thickness of the pressure-sensitive adhesive layer is not particularly limited, it is usually preferably 1 μm to 5 mm in consideration of the adhesive force and the ease of production. The pressure-sensitive adhesive layer can be provided on the decorative sheet by a laminating method or a coating method. In such a case, since a polyurethane resin having a siloxane bond in the molecule is used for the stabilizing resin layer, it is excellent in heat resistance and solvent resistance, and an adhesive can be directly coated on the stabilizing resin layer. It is.

The decorative sheet of the present invention can include a support layer. The support layer has the following functions in the present invention.

(A) Step film: When coating the raw material of the stabilizing resin layer on the support layer and curing the stabilizing resin layer, or when laminating the stabilizing resin layer, It plays a role as a process film when providing an adhesive layer.

(B) Reduction in the amount of the stabilizing resin layer used: Although the polyurethane resin having a siloxane bond in the molecule used for the stabilizing resin layer is much less expensive than the fluorine-based resin, This is because, compared to a normal urethane resin, it is more expensive, so that it is preferable to use as little as possible.

(C) Enhancement of self-supporting property and heat resistance: This is for further enhancing the self-supporting property and heat resistance of the decorative film according to the application.

(D) Improving the durability of the decorative sheet: This is to protect the decorative surface of the decorative sheet from an enemy environment such as ultraviolet rays, oxygen, and mechanical stimuli, thereby improving the durability of the decorative sheet.

Therefore, in order to secure such a function,
Specifically, it is preferable to use a resin film of polyvinyl chloride, polyurethane, acrylic, polyester, polypropylene, polyimide, polyamide or the like as the support layer. In addition, the thickness of the support layer is not particularly limited, but can be used in a range that does not impair the three-dimensional followability and decorativeness, which is the object of the present invention. Specifically, a thickness of 10 μm to 3 mm is preferable.

The support layer is in contact with the stabilizing resin layer, which is necessary to fulfill the function as a process film, but is in contact with the stabilizing resin layer for other purposes. It does not necessarily have to be in contact.

After applying the decorative sheet to the base material, the support layer can be peeled off if necessary, or can be left as it is.

In order to improve the adhesion between the support layer and the stabilizing resin layer, an adhesive layer may be separately provided.

The hologram processing surface and the hairline processing surface will be described below. It is also possible to apply the above-mentioned hologram treatment or hairline treatment directly to the stabilizing resin layer, or to provide a support layer and apply the hologram treatment or hairline treatment to the support layer. Further, after performing such a hologram process or a hairline process, it is also possible to combine a metal deposition process.

In the present invention, it is also possible to improve the usability of the decorative sheet by providing a release film on the adhesive layer without departing from the objects and effects of the present invention.
