This welding sheet is of a two-layer type, and a welding resin 4 in which a metal derivative 2 is contained in a thermoplastic resin sheet base material 1 and a thermoplastic resin sheet base material 5 contains a derivative. And a resin layer 6 which does not exist.

The sheet base material 1 containing the above and the sheet base material 5 for the composite layer not containing the derivative are integrated by the calendar rolls 7 and 8 to form a welded sheet having a two-layer structure.

A sheet base material 1 containing a derivative 2 is fed by a feed roll 9 to a printing plate having a printing pad 10. The sheet base material 5 for the colored (ink) layer, that is, the composite layer is formed by feeding the resin-based ink from the ink supply unit 12 to the sheet 11 and printing it.

る。The welded sheet formed as described above is used for joining plastic parts A and B made of different materials, for example, as shown in FIG. At that time, the sheet base material 1 of the welded resin layer 4 is made of a resin similar to that of the component A to be welded, and the sheet base material 5 of the resin layer 6 for the composite layer is made of a resin similar to that of the other component B. . Thereby, sufficient welding strength of the welded joint portion can be obtained, and the welded resin layer 4
It is possible to hide the color of the sheet base material 1 and the derivative 2, and it is possible to eliminate the problem in appearance due to the retained color of the welding sheet.

も利用することができる。That is, the sheet base material 1 of the welding resin layer 4 does not include a coloring material, and the sheet base material 5 for the composite layer is colored as necessary. Therefore, as shown in FIG. 3, when the design side of the product completed by fusion-bonding the transparent plastic component B to the plastic component A is the transparent plastic component B side, the retained color of the welding sheet causes a problem in appearance. Even if it occurs, the appearance can be corrected by appropriately coloring the resin layer 6 for the composite layer. Further, by intentionally coloring the resin layer 6, the resin layer 6 can be used for a color arrangement design.

Even if the materials of B and B are different from each other, as shown in FIG. 4A, the welding resin layer 4 of the welding sheet X of the present embodiment is the same type of resin as the component A, and the resin layer 6 for the composite layer is By using the same type of resin as the component B, it is possible to increase the joint strength as a product after welding.

接合することができる。Further, even when the materials of the parts A and B are completely different resins which are mutually incompatible with each other, as shown in FIG. 4B, the welding resin layer 4 of the same kind of material as the part A and the same kind of the part B of the same kind as the part A are used. By using the welding sheet X in which the second resin layer 6b made of a material having a good compatibility with each other is interposed between the first resin layer 6a made of a material, the parts A and B have sufficient welding strength. Can be joined.

まうので、母材を色素等で着色するだけでは色味をカバ
ーすることができない。Here, because of the appearance problem of the above-mentioned welding sheet X, for example, it is conceivable that a single layer structure as in the past is obtained by mixing a dye into the welding resin layer 4 to change the retained color. In the case of this single layer, since the fibrous derivative 2 such as stainless steel contained in the welding sheet X also appears on the surface thereof, the tint cannot be covered only by coloring the base material with a pigment or the like.
【００１７】また、溶着シートＸの母材（樹脂）の選択

味をカバーすることができない。Also, depending on the selection of the base material (resin) of the welding sheet X, it is necessary to use a material having a strong intrinsic color of the resin, and in this case as well, just by coloring the base material with a dye or the like, the tint will be improved. Cannot be covered.
【００１８】また、図４の（ｂ）に示す例で複合層用の
樹脂層６ａ，６ｂを二層としているのは、次の理由によ

関係が得られる。That is, when it is desired to join the parts A and B having a relationship of A + B = 0 (not welded) with each other with as much strength as possible, a resin layer a made of a material close to the part A and a resin layer b made of a material close to the part B are used. A welding sheet X is used in which a resin layer C made of a material compatible with both resin layers a and b is interposed.
At this time, when the strength after welding is represented by 10 points, Table 1
If the relationship of A is obtained, the relationship of A + B = 8 is apparently obtained.

できる。As described above, when joining parts A + B which are not welded at all, it is necessary to use a welding sheet having a multi-layer structure of two or more layers even if a material (resin) having a good compatibility is not found. It is possible to obtain a welded joint having various strengths.

果がある。As described above, according to the present invention, a welding resin layer containing a derivative in a sheet base material and at least one resin layer containing no derivative are laminated to form a multilayer structure. There is an effect that the appearance problem due to the retained color can be eliminated, and sufficient joining strength of the welded joint can be obtained even when joining plastic parts made of different materials.
