CONSTITUTION:A release layer 13, an ink layer 14, and an adhesive layer 15 are successively laminated on one surface of a base film F to form an image pattern layer 16. The release layer 13 and the ink layer 14 are laminated in irregular states along the irregular surface of the base film F. The adhesive layer 15 is laminated so that the surface to be bonded to the outer surface of a fairing 11 is made smooth. The base film F is brought into pressure contact with the outer surface of the fairing 11, the image pattern layer 16 is bonded thereto through the adhesive layer 15, the base film F is released, and an image pattern made of the ink layer 14 is transferred. The application of irregularities all over one surface of the base film F results in a shaded and shadowed image pattern of the reversed irregular part formed on the surface of the image pattern layer 16. Thus, various types of irregularities can be formed on the surface of the image pattern layer, and variety can be imparted to the outside appearances of various image patterns.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the outer surface of exterior parts, such as fairings, side covers, or The present invention relates to a painting method suitable for painting the outer surface of a tank or the outer surface of a ship's hull parts.

[Prior Art] Generally, stripes, marks, etc. (including letters) are painted on the outer surface of exterior parts such as motorcycle fairings to enhance the design effect. As a method, for example, as shown in Japanese Patent Publication No. 56-45768, a thermoplastic film on which a pattern is printed and an adhesive is laminated is positioned and placed on an exterior component, and then heated and softened. A technique is known in which the above-mentioned pattern is painted on the outer surface of the exterior component with the film covered by the film by press-bonding the film to the exterior surface of the exterior component.

[Problems to be Solved by the Invention] However, in the above technique, since the film is left covering the design, the painting is done later. Since the fairing is closed by the fairing and the film protrudes from the periphery of the fairing, it is necessary to remove the portion covering the opening and the film protruding from the periphery. There were drawbacks such as.

In addition, as a pattern for the fairing, for example, a watermark-like pattern can be created by making a part of the surface uneven, or the entire surface can be made into a matte state with minute unevenness, etc., to improve the appearance. If you want to bring about a change, it is difficult to achieve it using the above methods.

In view of the above circumstances, it is an object of the present invention to provide a painting method that not only allows simple and highly accurate painting to be performed, but also allows various changes to be made in the appearance of the surface. .

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a base printed with a pattern layer formed by laminating at least three layers, a release layer, an ink layer and an adhesive layer, on the outer surface of an exterior component. The film is pressure-bonded with the pattern layer facing the exterior component, then the base film is peeled off to transfer the design layer to the outer surface of the exterior component, and then the design layer is subjected to a curing treatment. This method is characterized in that the surface of the base film on the side on which the pattern layer is printed is textured in advance.

[Function] According to the method for painting the outer surface of the exterior component of the present invention, the base film is pressure-bonded to the outer surface of the exterior component and the pattern layer printed on the base film is transferred to the outer surface of the exterior component, thereby painting the exterior component. Improves the accuracy of alignment between parts and patterns,
Furthermore, by peeling off the base film after transfer, it is possible to open the opening formed in the exterior component and remove the protruding portion from the peripheral edge of the exterior component at the same time, thereby simplifying the work.

In addition, when applying unevenness to the surface of the base film on which the pattern layer is printed, if the unevenness is made fine and applied to the entire surface of the base film, the surface of the pattern layer becomes a fine uneven surface and becomes matte. Therefore, if an uneven part in the shape of a pattern such as a number or a mark is formed on a part of the base film, the uneven part will be reversed on the surface of the pattern layer and a watermark-like pattern with a shadow will be created. Various irregularities can be formed on the surface of the pattern layer, thereby bringing about various changes in the appearance of the pattern.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 in FIG. 1 indicates a motorcycle equipped with exterior parts to which this embodiment is applied, including a body frame 2, a front fork 3 rotatably mounted on the front part of the body frame 2, A steering handle 4 is attached to the upper end of the front fork 3, a front wheel 5 is rotatably attached to the lower part of the front auger 3, and a rear fork is swingably attached to the rear of the body frame 2. 6 and
A rear wheel 7 is rotatably attached to the swinging end of the rear fork 6, an engine 8 is attached to approximately the center of the vehicle body frame 2, and a fuel tank 9 is attached to the upper part of the vehicle body frame 2.

The outer surface of the fairing 11 is painted by the method according to this embodiment.

The fairing 11 is made of synthetic resin such as ABS or AES, or painted metal such as steel plate or aluminum, and has an air duct 12 opened in a portion facing the side of the vehicle body frame 2. ing. Here, among resin-based paints, those having polarity and low drying temperature, such as urethane-based paints, are preferably used as the paint used for the coating.

The outer surface of the fairing 11 is decorated with stripes extending from front to back, and the method for applying the stripes will be described below.

First, the structure of the base film F used in this embodiment will be explained.

As shown in Fig. 2, this base film F is obtained by cutting a base film material F, which is press-molded by sandwiching the film material between two rolls RR' into appropriate sizes. be. For the base film F, thermoplastic resins such as vinyl chloride, ABS, polycarbonate, polyethylene, polypropylene, polycarbonate, and composites thereof are used.

Here, a large number of minute protrusions are formed on the entire circumferential surface of one roll R' (lower side in Fig. 2), each having a height of microns and a distance between them. As shown in FIG. 3, minute recesses D1 formed by protrusions are formed on the entire surface of the film F on the roll R' side. That is, the base film F
Concave processing is applied to the entire one side.

Then, as shown in FIG. 4, a release layer 13 and an ink layer 14 are provided on one surface (lower surface in the figure) of the base film F.
, adhesive layers 15 are sequentially laminated to a predetermined uniform thickness to form a pattern layer 16. Each of these layers 13
．． 14.15, the release layer 13 and the ink layer 14 are similarly laminated on the uneven surface of the base film F, and the adhesive layer 15 is laminated on that surface, that is, the outer surface of the fairing 11. Each layer is sequentially laminated on the base film F by printing means such as silk printing, gravure printing, barcode printing, knife coating, etc. so that the surface to be adhered is smooth.

Note that FIG. 5 is a plan view of the base film F on which the pattern layer 16 is formed.

As the peeling layer 13, an ultraviolet curing resin, polyvinyl butyral, nitrocellulose, chlorinated rubber, etc. mixed with an appropriate photoinitiator or sensitizer are used.

The ink layer 14 may be made of ordinary ink or one that can better cope with the elongation of the base film F.
An ink using an acrylic-vinyl chloride resin binder and pigments with good weather resistance is used.

As the adhesive layer 15, either a thermoplastic resin or a thermosetting resin can be used; however, for example, when adhering to a resin or a painted surface on a resin, temperature restrictions and In terms of storage stability of the base film F, thermoplastic resins, particularly urethane-based thermoplastic resins, are preferred.

Next, a procedure for painting the outer surface of the fairing 11 using the base film F according to the method of this embodiment will be explained based on FIGS. 6 to 9.

First, a support shown at 18 in the figure is prepared. This support 1
8 has a shape whose upper surface follows the back surface of the air ring 11 of 7.

Then, as shown in FIGS. 6 and 7, the support 18 carrying the fairing 11 is set on the stand 20 in the vacuum container 19, and the base film 16 on which the pattern layer 16 is printed is set. F, pattern layer 16, fairing 1
facing the outer surface of 1, and the pattern and fairing 11
Place it in the vacuum container 19 while aligning with the
The inside of the vacuum container 19 is airtightly divided by the base film F.

Subsequently, after reducing the internal pressure of each of the divided chambers 21 and 22 formed in the vacuum container 19 by the base film F to the same vacuum pressure, the base film F is placed above the vacuum container 19. It is heated to an appropriate temperature by the provided heater H to soften it.

Thereafter, as shown in FIG. 8, the Uke raises the lifting mechanism 23 that supports the stand 20, so that the Uke raises the support 18 and the fairing 11 together with the stand 20, and bases the outer surface of the fairing 11 on the base. Bring it into contact with film F.

By opening the divided chamber 21 of the vacuum container 19 on the side where the fairing 11 is not disposed to the atmosphere and increasing its internal pressure, the base film F is attached to the fairing 11 as shown in FIG. by pressing it against the outer surface of the
The pattern layer 16 is attached to the fairing 11 by its adhesive layer 15.
Attach to the outer surface of the

Next, after taking out the fairing 11 from the vacuum container 19, the base film F is peeled off. In this state, the pattern formed by the ink layer 14 is transferred to the outer surface of the fairing 11. At this time, due to the flexibility of the base film F, the pattern layer 16 is
Since the outer periphery of the fairing 1 and the periphery of the air duct 12 are rolled up and slightly covered to the back side, the cut-off end of the pattern is located on the back side of the fairing 11, so that the appearance is not spoiled.

After such a removal operation of the base film F, the release layer 13 exposed on the fairing 11 is irradiated with ultraviolet rays to harden the release layer 13.

As a result, a hardened layer is formed on the surface of the pattern layer 16, making it possible to perform painting with high weather resistance and scratch resistance.
When applied to exterior parts such as the fairing 11 described above that are exposed to adverse conditions such as being sprayed with outside air, rain, and even mud, it is expected that the appearance will be maintained for a long period of time.

Note that such a curing treatment can also be performed by applying a clear coat to the surface of the pattern layer 16 without adding the ultraviolet curable resin. The paint used for this clear coating is urethane-based two-component paint for resin exterior parts, and high-temperature baking acrylic melamine paint for metal exterior parts (for example, fuel tanks). .

Furthermore, according to this embodiment, since one side of the base film F is subjected to fine unevenness processing, the surface of the pattern layer 16 laminated on the base film F also has the same shape as shown in Fig. 1θ. The surface of the pattern layer 16 has a finely uneven surface, so that the surface of the pattern layer 16 absorbs light and does not reflect much light, which is a so-called matte state.

In the above embodiment, the entire surface of the pattern layer 16 is made uneven by processing the entire surface of the base film F into a matte state. By forming uneven portions in the shape of a pattern such as, for example, the uneven portions can be reversed on the surface of the pattern layer 16 to form a shaded pattern, various types of unevenness can be formed on the surface of the pattern layer 16. This allows the appearance of various patterns to vary.

The present invention is not limited to the fairing 11 of a motorcycle l as in the above embodiments, but can also be applied to side covers and other exterior parts of motorcycles, as well as tricycles such as buggies, and four-wheeled vehicles such as passenger cars. It can also be applied to exterior parts of cars and ships.

Furthermore, the method of press-bonding the base film F to the exterior component may be any method other than the method described above.

[Effects of the Invention] As explained above, according to the method for applying the outer surface of an exterior component of the present invention, at least a release layer,

A method for painting the outer surface of an exterior component, comprising transferring the pattern to the outer surface of the exterior component, and then subjecting the surface of the pattern layer to a hardening treatment by applying a clear coating, the method comprising applying the pattern on the base film in advance. Since the surface on which the layer is printed is textured, the following effects can be achieved.

■It is possible to paint with high precision at the set position of the exterior parts, and even when painting across the discontinuous parts formed on the exterior parts, the edges of these discontinuous parts can be painted. To prevent deterioration of appearance by suppressing positional deviation between patterns between parts.

■If an opening is formed in the exterior part, it is possible to open the opening and remove the protruding part from the periphery by one operation of peeling off the base film, and painting makes the work easier. In addition, the painting can improve the weather resistance and scratch resistance of the surface of the subsequent design.

■When applying unevenness to the surface of the base film on which the pattern layer is printed, if the unevenness is made fine and applied to the entire surface of the base film, the surface of the pattern layer also becomes a fine uneven surface and becomes matte. If a part of the base film is formed with an uneven part in the shape of a pattern such as a number or a mark, the uneven part will be reversed on the surface of the pattern layer, forming a watermark-like pattern with a shadow. It is possible to form various irregularities on the surface of the pattern layer, such as by forming various irregularities on the surface of the pattern layer, thereby bringing about various changes in the appearance of the pattern.
