Description of the Related Art When a decorative board is fixed to a base material on a ceiling or a wall of a building, a method of attaching the decorative board to the base material with an adhesive is adopted. However, since the adhesive takes a long time to cure, it is necessary to temporarily fix the decorative board to the base material until this curing, and for that purpose, temporarily fix it with a double-sided adhesive tape with strong adhesive strength A new method is used in which a double-sided pressure-sensitive adhesive tape and an adhesive are simultaneously used and pressure-bonded, and the two-sided pressure-sensitive adhesive tape is temporarily bonded and the adhesive is permanently bonded. In this case, the base material has unevenness due to the warpage of the base building material itself, construction accuracy, traces of putting, and the like, and the decorative board also has unevenness and warpage. Therefore, in order to adhere the decorative board to the base material, the ability of the double-sided adhesive tape to follow the uneven surface of the adhered surface of the base material and the decorative board is extremely required. Conventionally, a double-sided pressure-sensitive adhesive tape having a foamed support having a cushioning property as a support has been used in order to provide the unevenness followability. This foam is compressed when pressed and pressed (compressed) with pressure, but it is restored to almost the original thickness of the double-sided adhesive tape when decompressed.

また貼り直しは大いに手間をとる問題があった。[0005] Therefore, when the above-mentioned temporary bonding is performed with the conventional double-sided pressure-sensitive adhesive tape 1 using such a foam, as shown in FIG. However, when the pressure is released as shown in (d), the thickness returns to the original thickness, and is separated from the concave surface, so that the adhesive area with the double-sided pressure-sensitive adhesive tape 1 is remarkably reduced, and the function of temporary adhesion cannot be performed. In addition, as shown in (c), the adhesive 5 spreads thinly by being pressed once, and then as shown in (d), when the pressure is released to restore the thickness of the tape, the base material 6 and the decorative plate 7 The adhesive layer is hardened in a state where the adhesive layer is roughened due to the widening of the clearance 8, and in some cases, the adhesive is separated from one of the adherends. Conventionally, in order to reduce this effect as much as possible, an adhesive is applied to a large number of eyes so as to be considerably higher than the thickness of the tape. Due to the above reasons, the decorative board, especially at the end, floats after a few days of construction, or, in extreme cases, the decorative board itself peels off and falls off. Forcibly peeling the floating veneer for this repair will damage the groundwork,
In addition, re-pasting had a problem of taking much time and effort.

According to the first aspect of the present invention, the thickness is 0.3 to 5 mm, preferably 0.5 to 3 mm, when the compression ratio is 50% or more and the return ratio after decompression is within 30% when pressed at 0.01 MPa. Double-sided adhesive tape having a conventional adhesive, for example, a well-known acrylic adhesive, a natural rubber-based adhesive or a synthetic rubber-based adhesive, on both sides of a support made of a foam of a high molecular compound Is adhered to an appropriate part of the adherend surface of one of the adherends in which two types of adherends, such as a decorative board and a base material, are uneven. Then, an adhesive is applied with a sufficient thickness to the adhered surface of the adherend other than where the double-sided adhesive tape is adhered. Next, the adherend surface of the adherend having the double-sided pressure-sensitive adhesive tape and the adhesive is superimposed on the adherend surface of the other adherend, and a pressing force is applied to press the adherends together. By this pressure bonding, the double-sided pressure-sensitive adhesive tape is compressed by 50% or more, and the double-sided pressure-sensitive adhesive tape is adhered to the entire surface of the adherend having irregularities. However, the double-sided pressure-sensitive adhesive tape of the present invention has a return rate after decompression of 5 minutes or less within 30%. During this time, the double-sided pressure-sensitive adhesive tape holds both adherends together without being restored to the original thickness. to continue. As a result, the adhesive pressure-bonded together with the double-sided adhesive tape is cured in the pressure-bonded state, and the cured adhesive between the adherends has no clearance or nest, and the two types of adherends A laminate having a double-sided pressure-sensitive adhesive tape and an adhesive layer cured at portions other than the double-sided pressure-sensitive adhesive tape over the entire surface is obtained.

Table 2 shows a comparative example. The composition of the foam as the support of the pressure-sensitive adhesive of the double-sided pressure-sensitive adhesive tape used in the present invention is described in Example No. 1 to No. 4
As shown in, is an emulsion or latex of a polymer compound having self-adhesion or contact properties, for example, an acrylic emulsion, an acrylic copolymer emulsion, a chloroprene latex, an SBR latex, a natural rubber latex, and the like. Used alone or as a mixture of two or more. Also,
Further, one or two of a tackifying resin emulsion or a polymer plasticizer for enhancing self-adhesiveness and contact properties are added. The foam cells 4 may be any of open cells, semi-open cells, and closed cells, but are preferably semi-open cells in terms of the compressibility, return rate, contact properties, and interlayer strength of the foam. Furthermore, the thickness of the support is 0.3-5 mm, but 0.5-3 mm
Are preferred. That is, if it is too thin, it is impossible to follow the unevenness of the adhered surface, and if it is too thick, the interlayer strength is reduced and there is a problem in design due to a step.
