[0010] There is a technology that uses a paint film containing an easily peelable layer to apply peelable paint to the body of a vehicle. Since such a paint film can be easily peeled off, the color of the body of the vehicle can be changed at any time. This allows, for example, the purchaser of a vehicle to choose a popular car body in the used car market. It is possible to choose a color, paint over it with your favorite color, and then restore the original color when you sell it. Also, applying a top coat of paint protects the original paint film, so the value of the used car can be increased compared to not applying a top coat of paint.

[0011] In this specification, "topcoat" refers to forming a peelable paint film on the original paint film of a vehicle after the fact. "(Paint) peeling" refers to removing the peelable paint film. "Topcoat painting" refers to a peelable paint that is applied over an existing paint film using a paint film that includes an easily peelable layer. In this specification, the term "painted film" refers to a paint film applied during the painting process, a peelable film, or a combination of these.

[0012] If such a system that allows easy repainting becomes widespread, it is expected that it will become difficult to estimate the history of a vehicle based on the appearance of the body alone. For example, immediately after the topcoat is peeled off, the vehicle will look like a new car, so the condition of the vehicle may not match its appearance. Furthermore, if a vehicle accident occurs that causes damage to the body paint, the accident history may be hidden by peeling off the topcoat. The vehicle according to the present disclosure solves such problems.

[0013] A vehicle according to a first aspect of the present disclosure is a vehicle having a first paint film and a second paint film formed on a vehicle body that can be peeled off afterwards. Specifically, the first paint film is formed on a first portion, the second paint film of the same color as the first paint film is formed on a second portion that cannot be seen from the outside of the vehicle, and the first paint film and the second paint film are not continuous at the boundary between the first portion and the second portion.

[0014] The later peelable paint film refers to a paint film that can be applied to a vehicle body and can be peeled off at any time. The paint film including an easily peelable layer may be, for example, a combination of a peelable film-like film and a normal paint film, or the paint film having a color may itself be peelable (hereinafter, easily peelable paint). By forming a paint film containing an easily peelable layer on top of the original paint film of a vehicle, the overcoat can be peeled off later (i.e., the vehicle body color can be restored). The overcoat can be easily peeled off by applying force from the outside.

[0015] In the vehicle according to the present disclosure, a paint film of the same color is formed on a first portion and a second portion. The second portion is a portion that is not visible from the outside of the vehicle in normal use. The first and second paint films are not continuous at the boundary between the first and second portions. In this configuration, when an attempt is made to remove the first paint film, the second paint film remains in a portion that cannot be seen from the outside of the vehicle, which makes it possible to leave evidence on the vehicle body that shows that the peelable paint film has been removed for some reason.

[0016] Hereinafter, specific embodiments of the present disclosure will be described with reference to the drawings. Unless otherwise specified, the configurations and the like described in each embodiment are not intended to limit the technical scope of the disclosure to those embodiments.

[0017] First Embodiment 1 is a perspective view showing a vehicle 1 according to this embodiment. The vehicle 1 has a plurality of exterior panels and exterior parts. The exterior panels are members that constitute the vehicle body, and include a bonnet hood 10, a roof panel 11, a front fender panel 12, a rear fender panel 13, front door outers 14, rear door outers 15, front pillars 16, center pillars 17, The exterior panels include a rear pillar 18. The exterior panels are typically steel panels, and are painted in a predetermined color when a new vehicle is manufactured. Moreover, the exterior parts are fitting parts that are attached to the vehicle body. The exterior parts are formed, for example, from resin. Examples of the exterior parts include a front bumper 20, a rear bumper 21, a rocker panel molding 22, and a side mirror 23. Like the outer panels, the exterior parts are also painted in a predetermined color when a new vehicle is manufactured. Note that some of the exterior parts may be painted in a color different from the above-mentioned color, or may be unpainted.

[0018] A paint film including an easily peelable layer is formed on the exterior panels and exterior parts. By overlaying a paint film including an easily peelable layer on the outer surface and side end face (or part of the back surface) of the exterior panels and exterior parts having a predetermined body color, the body color of the vehicle can be changed. Hereinafter, the exterior panels and exterior parts are referred to as body members.

[0019] Fig. 2 is a diagram explaining the location where such a coating film is formed. Fig. 2 is a diagram showing a cross section of a bonnet hood 10. The upper side of the drawing is the outer side of the vehicle, and the lower side is the engine room side. Reference numeral 10 denotes an outer panel, and the hatched area (reference numeral 10A) denotes a coating film including an easily peelable layer. The bonnet hood 10 is assumed to be painted in a specified color when the vehicle is manufactured. The dotted line indicates the front fender panel. As shown in the figure, the paint film including the easily peelable layer is formed at a position visible from the outside of the vehicle body.

[0020] Here, a paint film including an easily peelable layer will be briefly described. Fig. 3(A) is a schematic cross-sectional view showing a body member (e.g., a steel plate) of a vehicle body and a paint film applied to the body member. As shown in the figure, the body member has a steel plate 100 that has been metal-processed and has an electrodeposition layer formed thereon, and an intermediate coat layer 200, a base layer 300, and a clear coat layer 400 that are formed in this order on the electrodeposition layer. These layers correspond to the first layer of paint (the original paint of the vehicle).

[0021] A peelable layer 500 is formed on the outer surface of the body member as a second layer of paint. The peelable layer 500 is a layer of paint with easy peelability (easy peelable paint), and has the property of being easily peeled off by applying force compared to normal paint films. The peelable layer 500 is the "easy peelable layer" in this disclosure, and the paint film illustrated as the second layer is the "paint film including an easy peelable layer". The peelable layer 500 is formed by applying the easy peelable paint to the body member by, for example, a spray method. Examples of the easy peelable paint include paints made of xylene, ethylbenzene, an antioxidant, methyl ethyl ketone, a silica reactant, titanium oxide (nanoparticles), and an organic solvent.

[0022] The topcoat painting of the vehicle with the easily peelable paint can be performed at a specified vehicle base. This allows the vehicle body color to be easily changed (i.e., from the first vehicle body color to the second vehicle body color). The same can be said for peeling off the peelable layer 500. By peeling off the peelable layer 500 at a specified vehicle base, the vehicle body color can be returned to the original (i.e., from the second vehicle body color to the first vehicle body color).

[0023] In this example, a steel plate is used as the body member, but the body member may be a resin member. In this case, the intermediate coating layer 200 serves as a primer layer. A clear layer may be further provided on the peeling layer 500. By providing a clear layer, it is possible to provide a glossy appearance and improve weather resistance. In the example of Fig. 3(A), the paint itself is given easy peelability, but normal painting may be applied on a layer having easy peelability. For example, as shown in Fig. 3(B), an uncolored peelable layer 600 may be formed from the same material as the peelable layer 500, and a base layer 300A and a clear layer 400A may be formed on the peelable layer 600. The base layer 300A is a base It is a layer of paint having a color different from that of base layer 300. Even in such a form, the paint layer can be removed by peeling off peel-off layer 600. In this case, peel-off layer 600 is the "easily peelable layer" in this disclosure, and the paint film illustrated as the second layer is the "paint film including the easily peelable layer."

[0024] In this example, one color is used as the vehicle body color and the topcoat color, but multiple colors may be used. For example, the vehicle body color may be a combination of multiple colors arranged in a predetermined pattern. In addition, the term "color" in this specification may refer not only to a single layer, but also to a color expressed by multiple layers of paint or material. The multiple layers may include, for example, a clear layer, a glass flake layer, a mica layer, a pearl layer, etc. The topcoat may be applied to at least a part of the original paint. In other words, the topcoat does not have to cover the entire original paint. For example, if the original body color is black, a blue topcoat can be applied to a part of the original paint to obtain a two-tone black and blue vehicle.

[0025] In this embodiment, the paint film formed on the first portion and the paint film formed on the second portion are independent of each other and are not continuous with each other. The first portion is a portion at least a part of which can be seen from the outside when an opening such as a bonnet hood, a trunk lid, or a door is closed. The first portion may include both an area located on the front side of the body member and an area that wraps around to the back side of the body member. The second portion is a portion that is not visible from the outside. For example, the second portion may be a portion that is not visible from the outside when the opening is closed.

[0026] The arrangement of the first portion and the second portion will be specifically described with reference to the drawings. FIG. 4 is an enlarged cross-sectional view of the end of the bonnet hood 10 and the end of the front fender panel 12. The direction into the paper is the front-rear direction of the vehicle. The hatched parts (reference numerals 10A and 12A) are the first parts, and the blackened parts (reference numerals 10B and 12B) are the second parts. A coating film including an easily peelable layer is formed in the first part and the second part. As shown in the figure, since the second part is located inside the engine room, it cannot be seen from the outside of the vehicle when the bonnet hood is closed. The arrow indicates the boundary between the first part and the second part. At the boundary between the first part and the second part, the coating film is not continuous. In this state, when an attempt is made to peel off the easily peelable layer by applying force from the outside of the vehicle body, only the coating film corresponding to the first part (10A, 12A) is peeled off, and the coating film corresponding to the second part (10B, 12B) remains. This is because the paint film is separated between the first and second regions, and therefore the force attempting to peel off the paint film does not reach the second region. As a result, the paint film remains in a portion that cannot be seen from the outside, as shown in Figure 5. In other words, a vehicle with paint film remaining in a specified portion can be regarded as a vehicle with a history of having had the paint film including the easily peelable layer removed.

[0027] In addition, it is preferable that the end of the first portion and the end of the second portion are within a predetermined distance (preferably, about several centimeters to several millimeters) or are approximately adjacent to each other. By disposing both portions close to each other, it is possible to make the paint film look as if it is continuous. Further, in this example, the second portion is disposed inside the engine compartment, but the second portion may be disposed inside a luggage compartment (for example, a trunk room) or the like.

[0028] The location of the second portion will be described with reference to another example. 6 is a cross-sectional view showing the joint between the front door outer 14 and the rocker panel molding 22. As in FIG. 4, the hatched portion (reference numerals 14A and 22A) is the first portion, and the black portion (reference numeral 22B) is the second portion. The surface depth direction corresponds to the front-to-rear direction of the vehicle. As shown in the figure, the second portion is located at the bottom of the vehicle body, and therefore the second portion cannot be seen unless the vehicle is jacked up or the bottom of the body is looked into. Fig. 7 is a perspective view of the second portion as viewed from the bottom of the body. In this way, the second portion may be located at a position that cannot be seen from a normal viewpoint when using the vehicle.

[0029] The second portion may be a portion that cannot be seen by attaching an exterior part to the vehicle body. In other words, the second portion may be a portion that can be seen by removing the exterior part. Examples of such exterior parts include a front bumper, a rear bumper, a rocker panel molding, a roof rail, and a roof antenna. Such exterior parts are usually removed when a paint film is peeled off.

[0030] 8 is a perspective view showing an example in which a second portion is disposed on the joint surface between the roof rail and the vehicle body (roof panel). FIG 8 is an enlarged view of the dotted line portion in FIG 1. Reference numeral 81 denotes a roof rail, and reference numeral 82 denotes a joint surface between the roof rail and the roof panel. The joint surface 82 cannot be seen from the outside when the roof rail is attached. In the drawing, the hatched area (reference numeral 83) is the second portion. The boundary between the first portion and the second portion is concealed by the attached roof rail. That is, if the easily peelable layer is removed without removing the roof rail, the paint film remains in the hatched area 83. That is, a vehicle in which a paint film remains on the joint surface between the roof rail and the roof panel can be regarded as a vehicle that has a history of having had a paint film including the easily peelable layer removed. Although a roof rail is exemplified in this example, the second portion may be disposed in a location that is concealed by another exterior component.

[0031] FIG. 9 is a flowchart of a method for forming a paint film on a vehicle according to this embodiment. First, in step S11, a coating film is formed on a first portion. In this step, the coating film may be formed using an easily peelable paint, or a transparent peelable layer may be formed and then a coating may be applied. When the coating film is completely formed, the process proceeds to step S12. In step S12, a coating film is formed on the second portion. In this step, as in step S11, the coating film may be formed using an easily peelable paint, or a transparent peelable layer may be formed and then a coating may be applied over it. This results in a coating film that is not continuous with the first portion. Note that the order of steps S11 and S12 may be reversed.

[0032] As described above, in the vehicle according to the first embodiment, when forming a paint film including an easily peelable layer, the area to be painted is divided into a first area and a second area, and a paint film is formed independently for each area. Since the paint film is divided at a position that cannot be seen from the outside, when the easily peelable layer is removed by applying a force from the outside, the paint film remains inside. This makes it possible to determine after the fact whether or not there is a history of removing the easily peelable layer.

[0033] (Modification of the first embodiment) In the first embodiment, both the first and second regions are painted with an easily peelable paint. On the other hand, the second region may be painted with a normal paint that is not peelable. This embodiment also allows the paint to be checked after the fact for peeling of the paint film. Furthermore, in the first embodiment, a paint film of the same color is formed on both the first portion and the second portion, but as long as it is possible to determine that the paint has been peeled off, it is not necessary to paint both portions the same color.

[0034] In the first embodiment, the second portion is disposed in a location that is difficult to see during normal use, but the second portion may be disposed in a location that is difficult to reach from the outside. For example, the second portion may be disposed in a location in the engine compartment that cannot be accessed without removing a part. This makes it possible to prevent the paint film applied to the second portion from being removed.

[0035] In the first embodiment, the first and second parts are painted independently, but the painting process may be performed once, and the first and second parts may be separated by making a cut in the paint film that has been formed. For example, in the example of Fig. 4, a process of painting the hatched area and the black area together, and a process of cutting the paint film at the point indicated by the arrow may be performed.

[0036] (Other variations) The above-described embodiment is merely an example, and the present disclosure can be modified and implemented as appropriate without departing from the spirit and scope of the present disclosure. For example, the processes and means described in this disclosure can be freely combined and implemented as long as no technical contradiction occurs. [Explanation of symbols]
