【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 8 show an embodiment of the present invention. FIG. 1 is a front view of an automobile with a picture drawn on a hood, FIG. 2 is an enlarged view of the picture, and FIG. 3 is a front view of a masking jig. 4 and 5 are front views of an automobile in which a masking jig is magnetically attached to the bonnet, FIGS. 5 to 7 are explanatory views of the coating process, and FIG. 8 is an enlarged sectional view taken along line 8-8 of FIG.

As shown in FIG. 3, the masking jig J of the present embodiment is composed of a magnet sheet 1 that can be magnetically attached to the surface of a car body. The magnet sheet 1 is made by cutting a flexible sheet such as synthetic resin or rubber containing magnet powder into a rectangular shape, and has a thickness of 0.5 mm to 1.0 mm so as to closely adhere to a curved vehicle body surface without a gap. Have

The magnet sheet 1 is divided into an outer frame portion 2 and a picture portion 3 inside thereof, and the picture portion 3 is composed of a larger number of small pieces. That is, the pattern portion 3 includes a plurality of small pieces 4 (4a, 4b, 4c ...) corresponding to flowers, a plurality of small pieces 5 (5a, 5b, 5c ...) corresponding to leaves, and one piece corresponding to a stem. It is composed of a small piece 6 of No. 1, one small piece 7 corresponding to the calyx, and a plurality of small pieces 8 (8a, 8b, 8c ...) Corresponding to the bud. These small pieces 4, 5, 6, 7, 8 are cut from the magnet sheet 1 by die cutting, for example, and can be individually attached and detached. It should be noted that the respective parts in FIG. 2 showing the design are designated by the reference numerals corresponding to the respective small pieces 4, 5, 6, 7, 8 in FIG.

The boundaries of the small pieces 4, 5, 6, 7, 8 are determined as follows. For example, a real rose flower is photographed in a color photograph, first, parts with different colors are selected as boundaries, and even parts of the same color with distinct shadows are selected as boundaries. .

[0012] Explaining this in detail with reference to FIG. 2, the periphery of the red flower piece 4 (4a, 4b, 4c ...) And the green leaf piece 5 (5a, 5b, 5c ...) ), The outer circumference of the brown small piece 6 of the stem, the outer circumference of the green small piece 7 of the calyx, and the outer circumference of the red small piece of the bud 8 (8a, 8b, 8c ...) are selected as boundaries. It

Further, with respect to the plurality of small pieces 4 (4a, 4b, 4c ...) Of the flower, a portion having a difference in shade of red is selected as a boundary. For example, a petal 4a that is bright red due to strong light on the front side and a petal 4b that is dark red due to weak light on the other side are separated based on the shade of red. . Alternatively, even if the same petal has a dark red portion between the bright red portions 4h and 4i depending on the angle of light, both portions are separated based on the shade of red.

The plurality of small pieces 5 (5a, 5b, 5c ...) of green leaves and the plurality of small pieces 8 (8a, 8b, 8c ...) of red buds are colored in the same manner as the case of the flower described above. The boundary is determined based on the shading.

Next, a procedure for applying a rose flower pattern to the vehicle body of the automobile V using the above-mentioned masking jig J will be described. Note that, here, the paint color of the vehicle body of the automobile V is assumed to be a paint color other than white.

First, as shown in FIG. 4, only the frame portion 2 from which the pattern portion 3 of the masking jig J is removed is magnetically attached to a predetermined portion of the hood B of the automobile V. At this time, the shaded area in Fig. 5 is open and the vehicle body surface is exposed. To this exposed area, apply a white urethane base paint with an air brush to a thickness of 5 µm to 10 µm, and apply a white base coating. Form a film. After the base coating film is dried, the small pieces 5, 6, 7 and 8 are magnetically attached to the parts other than the flower of the pattern, that is, the leaves, the stems, the calyx and the buds. As a result, only the plurality of small flower pieces 4 (4a, 4b, 4c ...) Are removed as shown by the hatched lines in FIG. 6, and the white base coating film is exposed there.

Subsequently, a red urethane-based paint is applied to the shaded portion of FIG. 6 with an air brush to a film thickness of 5 μm to 10 μm to form a pattern coating film corresponding to the flower of the pattern. In this way, by forming the white base coating film before applying the red urethane coating material, it is possible to improve the coating quality by vividly coloring the pattern coating film of the red urethane coating material. .

After the pattern coating film is dried, for example, other small pieces 4 (4a, 4b, 4c ...) Except for the small piece 4e of a flower are magnetically adhered to the small piece 4e as shown by the diagonal lines in FIG. Open the corresponding part to expose the red urethane paint pattern coating. Next, apply a black urethane paint with an air brush to a part of the shaded area in Fig. 7 (A), and form a shaded coating so that the lightness and darkness gradually changes as shown in Fig. 7 (B). To do. In addition, when shading a dark-colored pattern paint film, use a paint in which a black paint is appropriately mixed with the dark-color paint, or use the black paint alone. When shading a light-colored paint film, use a paint in which a black paint is appropriately mixed with the light-colored paint.

When the shadow coating film is dried, the small piece 4e is magnetically attached to remove any one of the other small pieces 4 (4a, 4b, 4c ...), and the shadow coating film is formed on the portion with an air brush. To do. Then, the above work is sequentially repeated for all the small pieces 4 (4a, 4b, 4c ...) Of the flower to complete the flower portion of the pattern.

Subsequently, the green leaf portion, the brown stem portion, the green calyx portion and the red bud portion are painted in the same procedure as the above-mentioned flower portion. Prior to removing the frame portion 2 of the magnet sheet 1 from the vehicle body after the design is completed, spray a thinner on the design. This makes it possible to completely cut off the coating film of the pattern from the frame portion 2 and prevent the pattern from peeling when the frame portion 2 is removed from the vehicle body.

Next, a urethane clear paint is applied to the pattern and its periphery to form a clear coating film of 20 μm to 60 μm, thereby completing the rose flower pattern shown in FIG. By forming a clear coating film in this way, it is possible to prevent the peeling of the design and to give the design a deep luster and three-dimensional effect to improve the coating quality.

Then, as shown in FIG. 8, the pattern which is applied over the undercoat coating film, the intermediate coating film and the top coating film formed on the steel plate of the vehicle body is a white base coating film. It is composed of 4 layers: red, green or brown picture paint film, black paint film, and clear paint film.

As described above, it is possible to coat a multicolored pattern with one masking jig J, and since this masking jig J can be repeatedly used, the cost is extremely low. Further, since the frame portion 2 of the magnet sheet 1 does not need to be removed from the beginning to the end of painting the pattern, there is no risk of misalignment of each part of the pattern. Moreover, the pattern part is divided into a plurality of small pieces 4,5,6,7,8, and one of the small pieces 4,5,6,7,8 is removed and shaded. Not only is it possible to paint a three-dimensional pattern with a deep expression, but it is possible to reliably prevent unnecessary adhesion of paint to other parts.

The case of painting a design on a vehicle body of a coating color other than white has been described above. However, when painting a design on a vehicle body of a white color, a light blue type or a pale yellow type paint is applied to the base coating. By using it, it is possible to improve the coating quality by vividly coloring the pattern to be painted on it.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design changes can be made.
