BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the drawings, wherein A is a metal siding,
The metal siding A is formed by bending connecting portions 2 that can be fitted and connected to each other at both ends in the width direction. For example, a metal surface plate 1 made of a steel plate and a back surface of the metal surface plate 1 are foam-filled.
For example, a core material 3 made of a resin foam such as a phenolic resin or a polyurethane resin, and a back material 4 on the back surface of the core material 3 such as aluminum laminated kraft paper are provided.

At this time, the metal surface plate 1 of the metal siding A has a projecting pattern 11 protruded from the metal surface plate 1 by drawing and the lowermost layer of the metal surface plate 1 and its coating,
For example, a base layer 12 formed by painting the entire surface and the base layer 1
2, a multi-colored pattern layer 15 formed by a plurality of partial roll coatings and / or partial printings on the protruding pattern 11, a surface protective layer 16 as the uppermost layer of the metal surface plate 1, and The surface protective layer 16 is formed of a matte clear paint containing 5 to 30% by weight of beads 17, and in the present example, the projecting pattern 11 formed by the drawing is partially peeled off. ,
It is made into an aged brick shape in which chipping, deterioration unevenness and the like are exposed, and the multicolor pattern layer 15 is made into the aged brick color and has a multicolored color tone formed by multiple times of partial roll coating and / or partial printing. The base layer 12 has a base or joint color tone or, alternatively, the base or joint color portion of the base layer 12 is formed by the coating layer 13 of the color to the base layer 12.

In this embodiment, the metal surface plate 1 is a base layer 1
2 is roll-formed using a color steel plate provided in advance as a baked painted surface, and the above-described connecting portion 2 at the end is formed by roll-forming on the surface together with the forming of the connecting portion 2 at the end, for example, by a height of several mm. The above-mentioned aged brick shape is exposed and given a predetermined coating or printing to obtain the above-mentioned metal siding A. In this case, in this example, the drawn metal surface plate is applied. 1 is a siding structure having the core material 3 and the back surface material 4, and the metal siding A is configured by applying post-processing painting or printing to the siding structure.

In the present embodiment, the plurality of pattern layers 15, the respective paints or inks of the undercoat or joint color coating layer 13 or the matte clear paint of the surface protective layer 16 which are used as required, are weatherable as siding. In order to ensure the property and avoid the use of toxic solvents, these are each made of a paint or ink based on acrylic water, especially acrylic, acrylic emulsion or acrylic urethane.

At this time, the beads 17 contained in the matte clear coating of the surface protective layer 16 of the present embodiment are, for example, glass beads, urethane resin beads, acrylic resin beads, etc., which change yellowing due to deterioration thereof.
