Description

[Detailed description of the invention] The present invention relates to a decorative base material having a metallic luster pattern, more specifically having a pattern consisting of a metallic luster part colored in an arbitrary color and a faded metallic luster part. Decorative substrates, e.g. glass products,
This relates to plastic products and metal products.

An object of the present invention is to provide a decorative base material having a metallic luster pattern that has an excellent design effect and is excellent in durability, productivity, and economic efficiency.

BACKGROUND ART Conventionally, the surfaces of base materials such as glass products, plastic products, metal products, etc. are decorated with metallic luster patterns, which have been obtained in the following manner. That is, (1) a release layer is provided on a base sheet such as paper or plastic film, a matting agent layer and a transparent colored layer are partially provided on the release layer in alignment with each other, and a metallic luster thin film layer is further provided on top of the release layer. (2) After printing and applying a paint containing a pigment with a metallic feel to the surface of the base material using a transfer material made by sequentially laminating adhesive layers, the surface of the base material has a metallic luster. Hot-stamped stamping foil with a metallic luster thin film layer as one constituent layer on the necessary areas,
(3) Instead of applying a paint containing a pigment with a metallic feel, a release layer is provided on the base sheet,
A pigment layer using a pigment with a metallic feel is provided thereon as a coloring agent, and after transfer printing processing is performed using a transfer material made by laminating an adhesive layer on top of the pigment layer, the above-mentioned
Similar to (2), hot stamping is applied to the areas where metallic luster is required. (4) A peeling layer is provided on the base sheet, a colored layer is partially provided on top of the peeling layer, and a metallic luster is further applied on top of that. Using a transfer material provided with a thin film layer and an adhesive layer, and a mold consisting of a smooth plate and an eraser plate, a metallic luster consisting of a metallic luster part and an eraser-like metallic luster part is created at the same time as the transfer printing process. There are things that appear with patterns.

However, each of these decorative substrates having a metallic luster pattern has the following drawbacks, and a satisfactory one has not yet been obtained. In other words, in the case of the product (1), the transfer material used for manufacturing requires registration that is extremely difficult in industrial terms, and if even the slightest deviation occurs in the registration, a product with significantly inferior design effect will be obtained. I can't. Products in (2) and (3) (i) hot stamped using stamping foil have extremely low resistance in areas that require metallic luster, and (ii) require a process of providing a pigment layer and hot stamping. Because of this, the work is time-consuming and is inferior in economic efficiency and productivity. For products in (4), (i) the molds used during manufacturing are expensive, (ii) the design effect is poor because it is difficult to express delicate patterns, and (iii) the transfer printing process It has drawbacks such as difficulty in registration.

The inventors of the present invention have completed various experiments and considerations in view of the above points, and as a result have completed the present invention.
That is, in the present invention, an adhesive layer is formed on the surface of the base material,
A pigment layer containing a pigment having a metallic appearance is formed thereon, a metal thin film layer is partially formed on the pigment layer, and a resin layer is further formed on top of the pigment layer, and the resin layer is in contact with the metal thin film layer. This is a decorative base material having a metallic luster pattern, characterized in that only some parts are dyed in an arbitrary color.

Hereinafter, the decorative base material having a metallic luster pattern according to the present invention will be explained in detail based on the drawings.

The base material 1 used in the present invention may have a quadratic plane or a curved surface, and examples thereof include glass products, plastic products, metal products, and the like.

As shown in FIG. 1, a pigment layer 3, a metal thin film layer 4, and a partially dyed resin layer 5 are formed on the surface of this base material 1 via an adhesive layer 2. The pigment layer 3 is a layer containing a pigment having a metallic appearance, and is a layer exhibiting a faded metallic luster. To form the adhesive layer 2, pigment layer 3, metal thin film layer 4, and resin layer 5, transfer printing may be performed on the surface of the base material 1 using a transfer material 6 to be described later.

Next, a method for creating this transfer material will be explained.

As shown in Figure 2-e, the layer structure of the transfer material includes a base sheet 7, a resin layer 5, a metal thin film layer 4, a pigment layer 3,
It consists of an adhesive layer 2.

As the base sheet 7, single or composite films of polyester, polypropylene, polyethylene nylon, cellophane, etc., or films whose surfaces are subjected to mold release treatment, etc. can be used.

A resin layer 5 is provided on the base sheet 7. The resin layer 5 is formed using a resin that can be peeled off from the base sheet 7. Examples of such resins include acrylic resins, vinyl resins, cellulose resins, chlorinated olefin resins, thermosetting acrylic resins, and epoxy resins. This resin layer 5 is preferably a transparent resin layer because it transfers to the transferred object side after transfer and also plays the role of surface protection.
This resin layer 5 may be colored.

After a primer layer for metal thin film is provided as necessary on the base sheet 7 on which the resin layer 5 is provided, a water-soluble resin layer 8 is applied to the areas where a faded metallic luster is required.
will be established. (See Figure 2-a). The water-soluble resin layer 8
When dyeing the resin layer 5 or the primer layer for metal thin film with a dye solution, the dye is required to act as a resist dyeing layer, so it is necessary to appropriately select and use a dye that is difficult to dye depending on the composition of the dye solution. Examples of such water-soluble resins include water-soluble cellulose resins such as polyvinyl alcohol and methyl cellulose.

After providing the water-soluble resin layer 8, a colored layer 9 is provided using a dye solution (see Figure 2-b). The colored layer 9 is a layer provided for dyeing the portion of the resin layer 4 where the water-soluble resin layer 8 is not provided, and the dyed portion exhibits a metallic luster colored in an arbitrary color. become a part. This dyeing is thought to be achieved by the solvent in the dye solution swelling the surface of the resin layer 5, but it can be dyed even more strongly by heat treatment if necessary.

Further, unlike general inks, it is preferable to use an ink that does not contain a binder as the dye solution.
This is to prevent the binder from interfering with the dissolution of the water-soluble resin layer 8 in the subsequent cleaning process even if the colored layer 9 is provided over the water-soluble resin layer 8. This makes registration, which is extremely difficult industrially, unnecessary.

After the colored layer 9 is provided and the resin layer 5 is partially dyed, the metal thin film layer 4 is provided (see Figure 2-c). This metal thin film layer 4 is formed using a metal such as aluminum, chromium, silver, copper, or tin, for example, by vacuum evaporation.

After the metal thin film layer 4 is provided, it is washed to remove unnecessary materials such as the water-soluble resin layer 8 and the colored layer 9 on the water-soluble resin layer, and then dried (see Figure 2-d).

After drying, a pigment layer 3 containing a pigment having a metallic appearance is provided on top of the metal thin film layer 3. This pigment layer 3 becomes a portion that reveals a faded metal surface. As the colorant used, a paste made of metal powder such as aluminum or brass with stearic acid, oleic acid, etc. is suitable. As the resin binder used, acrylic, vinyl, thermosetting acrylic melamine, epoxy, etc. can be used. The degree of fading of the faded metal surface obtained by this pigment layer 3 can be arbitrarily determined by selecting the pigment, and
It can be adjusted using matting agents such as silica and calcium carbonate. Incidentally, the pigment layer 3 may be formed by mixing pigments or dyes other than metal powder into the ink, if necessary, to reveal a colored metal surface.

Thereafter, an adhesive layer 2 is provided on the pigment layer 3 (see Figure 2-e). As the adhesive layer 2, for example, resins such as vinyl/melamine, thermosetting acrylic, epoxy, and polyester/melamine can be used.

The thus obtained transfer material 6 is used to perform transfer printing on the surface of the substrate 1, and then the substrate 1 is heated at 150° C. to 180° C.
The decorative substrate having the metallic luster pattern according to the present invention can be obtained by subjecting the substrate 1 to a heat treatment at 400° C. for 15 to 30 minutes to harden the thermosetting resin in the transfer layer. If the substrate 1 is made of glass, metal, or heat-resistant material such as phenol or melamine resin, the substrate surface can be pretreated as necessary (e.g., silane coupling treatment, acid treatment, etc.) before transfer printing to obtain a decorative substrate having a metallic luster pattern with stronger adhesion.

Since the decorative base material having a metallic luster pattern according to the present invention has the above-described structure, it has the following effects. That is, in the present invention, the part with metallic luster is composed of a metal thin film layer, so that a surface with excellent brightness can be obtained, while the part with metallic luster is made of a pigment and matting agent with a metallic feel. Since the paint film is constructed and heat treated, the pigment and matting agent become rough on the surface due to shrinkage during curing of the coating film, and a surface having an arbitrary degree of matteness can be obtained. Further, since there is no misregistration between the highly lustrous metallic luster portion and the faded metallic lustrous portion, the design effect is excellent.

Furthermore, the manufacturing process of the present invention only involves transfer printing using a transfer material, and the manufacturing process of the transfer material does not require registering, which is extremely difficult industrially, so productivity is improved. It is highly economical. Furthermore, since this transfer material is firmly adhered to the base material by baking, it has extremely excellent durability, especially adhesion strength.

Therefore, the decorative base material having a metallic luster pattern according to the present invention has extremely high practical value.
